Clinically, metastatic involvement may affect the pericardium, myocardium, endocardium, valves, coronary arteries, or the cardiac conduction system. The consequences range from incidental imaging findings to life-threatening presentations such as pericardial effusion with cardiac tamponade, malignant arrhythmias, acute heart failure physiology, or obstructive intracardiac masses.<\/p>\n\n\n\n<p>From a diagnostic standpoint, Cardiac Metastasis forces careful differential diagnosis. Findings such as a new pericardial effusion, an unexplained elevation in right-sided pressures, or a new conduction block on electrocardiogram (ECG) can reflect metastatic infiltration, treatment-related cardiotoxicity, infection, thromboembolism, or primary cardiac tumors. The cardiology role is often to clarify anatomy and hemodynamics (e.g., via transthoracic echocardiography [TTE] or transesophageal echocardiography [TEE]), triage urgent complications, and coordinate with oncology on the likely etiology and next steps.<\/p>\n\n\n\n<p>For early-career clinicians, Cardiac Metastasis is also an exam-relevant concept because it connects core cardiac pathophysiology (tamponade physiology, restrictive physiology, arrhythmia mechanisms) with systemic disease. It illustrates why new cardiopulmonary symptoms in cancer patients deserve a broad, structured approach rather than assuming a single cause.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Indications \/ use cases<\/h2>\n\n\n\n<p>Cardiac Metastasis is typically considered in scenarios such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Known malignancy with <strong>new dyspnea<\/strong>, chest discomfort, orthopnea, or unexplained fatigue<\/li>\n<li><strong>New pericardial effusion<\/strong> on imaging, especially if recurrent or rapidly accumulating<\/li>\n<li>Clinical concern for <strong>cardiac tamponade<\/strong> (hypotension, tachycardia, elevated jugular venous pressure, pulsus paradoxus)<\/li>\n<li><strong>New arrhythmias<\/strong> (e.g., atrial fibrillation) or ventricular ectopy in a patient with cancer<\/li>\n<li><strong>New conduction abnormalities<\/strong> (e.g., atrioventricular [AV] block, bundle branch block) suggesting conduction system involvement<\/li>\n<li>Signs of <strong>right heart strain<\/strong> or obstruction (e.g., elevated right-sided pressures, tricuspid inflow obstruction)<\/li>\n<li><strong>Unexplained heart failure<\/strong> findings, especially with preserved ejection fraction and suspected infiltrative\/restrictive physiology<\/li>\n<li><strong>Incidental cardiac mass<\/strong> detected on CT, MRI, or PET performed for cancer staging<\/li>\n<li>Suspected <strong>tumor thrombus<\/strong> extension into the right atrium or inferior vena cava (classically in some renal or hepatic malignancies)<\/li>\n<li>Persistent <strong>pericarditis-like<\/strong> symptoms with systemic cancer features<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Contraindications \/ limitations<\/h2>\n\n\n\n<p>Cardiac Metastasis is a disease process rather than a procedure, so \u201ccontraindications\u201d apply most directly to diagnostic strategies and interventions used to evaluate or manage it.<\/p>\n\n\n\n<p>Key limitations and situations where alternative approaches may be preferred include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Non-specific symptoms:<\/strong> Dyspnea, chest pain, and tachycardia are common in cancer patients for many reasons (anemia, infection, pulmonary embolism, treatment effects), limiting clinical specificity.<\/li>\n<li><strong>Imaging constraints:<\/strong> Cardiac MRI quality can be limited by arrhythmia, inability to breath-hold, severe claustrophobia, or incompatible implanted devices (varies by device, material, and institution).<\/li>\n<li><strong>Contrast limitations:<\/strong> CT or MRI contrast may be avoided or modified in severe kidney dysfunction or prior contrast reactions (varies by clinician and case).<\/li>\n<li><strong>Biopsy feasibility and risk:<\/strong> Tissue confirmation may be difficult if the lesion is small, highly vascular, in a risky location, or if the patient is unstable; procedural risk-benefit varies by clinician and case.<\/li>\n<li><strong>Attribution challenges:<\/strong> Cardiac findings may reflect <strong>treatment-related cardiomyopathy<\/strong>, myocarditis, ischemia, or infection rather than metastasis; over-attribution can misdirect care.<\/li>\n<li><strong>Therapeutic limitations:<\/strong> Even when identified, definitive local therapy may not be feasible due to advanced systemic disease, frailty, coagulopathy, or limited expected benefit.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How it works (Mechanism \/ physiology)<\/h2>\n\n\n\n<p>Cardiac Metastasis occurs when malignant cells spread from a primary tumor site to cardiac structures. The main metastatic pathways include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lymphatic spread<\/strong> (commonly implicated in pericardial involvement)<\/li>\n<li><strong>Hematogenous spread<\/strong> through the bloodstream (often associated with myocardial deposits)<\/li>\n<li><strong>Direct extension<\/strong> from adjacent structures (e.g., mediastinal tumors)<\/li>\n<li><strong>Transvenous extension<\/strong> along large veins into the right heart (tumor thrombus phenomenon)<\/li>\n<\/ul>\n\n\n\n<p>The physiologic impact depends on the <strong>anatomic compartment<\/strong> involved:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pericardium:<\/strong> Metastases can cause pericardial inflammation and increased fluid production, leading to <strong>pericardial effusion<\/strong>. Rapid accumulation can impair ventricular filling and produce <strong>tamponade physiology<\/strong> (equalization of diastolic pressures, reduced stroke volume, compensatory tachycardia).<\/li>\n<li><strong>Myocardium:<\/strong> Infiltration can reduce compliance and contribute to <strong>diastolic dysfunction<\/strong> and restrictive-like filling patterns. It can also provoke arrhythmias by disrupting myocyte architecture.<\/li>\n<li><strong>Conduction system:<\/strong> Involvement of the sinoatrial (SA) node region, AV node, or His-Purkinje system can lead to bradyarrhythmias, AV block, or bundle branch block seen on ECG.<\/li>\n<li><strong>Endocardium\/valves and intracavitary masses:<\/strong> Lesions can obstruct inflow\/outflow (e.g., right ventricular outflow tract obstruction), mimic valvular disease, or act as a nidus for thrombus.<\/li>\n<li><strong>Coronary arteries:<\/strong> External compression or invasion is less common but can contribute to ischemia-like symptoms; distinguishing from atherosclerotic coronary artery disease may be challenging.<\/li>\n<\/ul>\n\n\n\n<p>\u201cOnset and duration\u201d are not properties of Cardiac Metastasis in the way they are for a drug. Instead, the clinical course is influenced by tumor biology, overall cancer burden, and whether the cardiac involvement is focal (mass effect) versus diffuse (infiltrative).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cardiac Metastasis Procedure or application overview<\/h2>\n\n\n\n<p>Cardiac Metastasis is assessed and managed through a coordinated evaluation rather than a single procedure. A typical high-level workflow is:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>\n<p><strong>Evaluation \/ exam<\/strong>\n   &#8211; Review cancer history (primary type, stage, treatments), symptom timeline, and hemodynamic stability.\n   &#8211; Focused cardiovascular exam for volume status and tamponade signs; review vitals and oxygenation.<\/p>\n<\/li>\n<li>\n<p><strong>Diagnostics<\/strong>\n   &#8211; <strong>ECG<\/strong> to assess rhythm, ischemia-like changes, and conduction disturbances.\n   &#8211; <strong>TTE<\/strong> as the first-line test for pericardial effusion, chamber compression, ventricular function, and visible masses.\n   &#8211; <strong>TEE<\/strong> when better definition is needed (e.g., atrial masses, valve-adjacent lesions) or when TTE windows are limited.\n   &#8211; <strong>Cardiac MRI<\/strong> for tissue characterization and extent (often helpful in differentiating tumor from thrombus).\n   &#8211; <strong>CT<\/strong> for anatomic detail, extracardiac extension, and surgical planning considerations.\n   &#8211; <strong>PET<\/strong> (when available\/appropriate) to assess metabolic activity and support staging context.\n   &#8211; Labs may include markers of inflammation or myocardial injury, but interpretation is context-dependent and non-specific.<\/p>\n<\/li>\n<li>\n<p><strong>Preparation (when intervention is considered)<\/strong>\n   &#8211; Multidisciplinary planning with oncology, cardiology, anesthesia, and cardiothoracic surgery as needed.\n   &#8211; Review anticoagulation status and bleeding risk if pericardiocentesis or biopsy is contemplated (varies by clinician and case).<\/p>\n<\/li>\n<li>\n<p><strong>Intervention \/ testing (case-dependent)<\/strong>\n   &#8211; <strong>Pericardiocentesis<\/strong> for symptomatic effusion or tamponade physiology; fluid may be sent for cytology and other studies.\n   &#8211; <strong>Surgical pericardial window<\/strong> in selected recurrent effusions (approach varies by institution).\n   &#8211; Selected patients may undergo <strong>biopsy<\/strong> (percutaneous or surgical) if tissue confirmation will change management.\n   &#8211; Treatment may include systemic therapy, radiotherapy, or surgery for obstruction, depending on tumor type and overall plan (varies by clinician and case).<\/p>\n<\/li>\n<li>\n<p><strong>Immediate checks<\/strong>\n   &#8211; Post-drainage echocardiography for residual effusion and hemodynamic response.\n   &#8211; Rhythm monitoring if arrhythmia risk is present.<\/p>\n<\/li>\n<li>\n<p><strong>Follow-up \/ monitoring<\/strong>\n   &#8211; Repeat imaging to track effusion recurrence or mass progression.\n   &#8211; Ongoing symptom and hemodynamic assessment integrated with oncology treatment cycles.<\/p>\n<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Types \/ variations<\/h2>\n\n\n\n<p>Cardiac Metastasis can be categorized by <strong>location<\/strong>, <strong>pattern<\/strong>, and <strong>route of spread<\/strong>.<\/p>\n\n\n\n<p><strong>By anatomic location<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pericardial metastasis:<\/strong> Often presents with pericardial effusion or pericarditis-like symptoms.<\/li>\n<li><strong>Myocardial metastasis:<\/strong> May be focal or diffuse; associated with arrhythmias, diastolic dysfunction, or heart failure symptoms.<\/li>\n<li><strong>Endocardial\/valvular involvement:<\/strong> Less common; may cause intracavitary masses or functional valve obstruction\/regurgitation.<\/li>\n<li><strong>Intracavitary tumor thrombus extension:<\/strong> Tumor growth along venous structures into cardiac chambers.<\/li>\n<\/ul>\n\n\n\n<p><strong>By pattern<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Focal mass lesion:<\/strong> Discrete tumor deposit with potential obstruction or embolic\/thrombotic complications.<\/li>\n<li><strong>Diffuse infiltrative disease:<\/strong> More likely to impair compliance and create restrictive physiology.<\/li>\n<\/ul>\n\n\n\n<p><strong>By metastatic pathway<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lymphatic<\/strong>, <strong>hematogenous<\/strong>, <strong>direct invasion<\/strong>, or <strong>transvenous extension<\/strong> (as above).<\/li>\n<\/ul>\n\n\n\n<p><strong>By primary tumor association (examples)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Frequently discussed primaries include <strong>lung cancer<\/strong>, <strong>breast cancer<\/strong>, <strong>melanoma<\/strong>, and hematologic malignancies such as <strong>lymphoma<\/strong> or <strong>leukemia<\/strong>.

Patients with prior malignant pericardial effusion are often monitored for recurrence using symptoms plus repeat echocardiography when clinically indicated. Those with myocardial or conduction system involvement may require rhythm surveillance (e.g., telemetry in acute settings, ambulatory monitoring in select cases) guided by clinical context.<\/p>\n\n\n\n<p>Outcomes vary widely and depend on factors such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Primary cancer type and responsiveness<\/strong> to systemic therapy<\/li>\n<li><strong>Extent of cardiac involvement<\/strong> (isolated pericardial disease vs diffuse myocardial infiltration)<\/li>\n<li>Presence of <strong>tamponade physiology<\/strong>, obstructive lesions, or refractory arrhythmias<\/li>\n<li>Baseline <strong>cardiovascular reserve<\/strong> and comorbidities (e.g., coronary artery disease, cardiomyopathy, chronic kidney disease)<\/li>\n<li>Treatment tolerance and feasibility; approach varies by clinician and case<\/li>\n<\/ul>\n\n\n\n<p>Because Cardiac Metastasis often occurs in advanced malignancy, outcome discussions typically emphasize realistic goals of care, symptom control, and prevention of acute decompensation. The specifics of monitoring intervals and escalation thresholds vary by clinician and case.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Alternatives \/ comparisons<\/h2>\n\n\n\n<p>In practice, the key \u201calternatives\u201d are competing diagnoses and different management pathways.<\/p>\n\n\n\n<p><strong>Compared with primary cardiac tumors<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Primary tumors (e.g., atrial myxoma) originate in the heart and may have different imaging features and surgical considerations.<\/li>\n<li>Cardiac Metastasis is more often associated with known systemic malignancy and may be multifocal or pericardial-predominant.<\/li>\n<\/ul>\n\n\n\n<p><strong>Compared with intracardiac thrombus<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Thrombus is common in low-flow states (e.g., severe left ventricular systolic dysfunction), atrial fibrillation, or hypercoagulable states (including malignancy).<\/li>\n<li>Cardiac MRI and contrast-enhanced imaging can help differentiate thrombus from tumor in some cases, but results are not always definitive.<\/li>\n<\/ul>\n\n\n\n<p><strong>Compared with infective endocarditis or nonbacterial thrombotic endocarditis<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Vegetations are typically valve-associated and accompanied by clinical context (fever, bacteremia, embolic events) or hypercoagulable malignancy contexts.<\/li>\n<li>Echo findings can overlap, so blood cultures, inflammatory markers, and systemic assessment remain important.<\/li>\n<\/ul>\n\n\n\n<p><strong>Management approach comparisons<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Observation\/monitoring<\/strong> may be appropriate for incidental, asymptomatic findings where immediate intervention would not change care (varies by clinician and case).<\/li>\n<li><strong>Medical therapy<\/strong> is generally supportive in cardiology terms (e.g., rate control for arrhythmias, diuretics for congestion) while oncology-directed therapy addresses the underlying driver.<\/li>\n<li><strong>Interventional procedures<\/strong> such as pericardiocentesis address acute physiology (tamponade\/effusion) rather than curing malignancy.<\/li>\n<li><strong>Surgical options<\/strong> (mass resection, pericardial window) may be considered for selected obstructive or recurrent effusion scenarios, balanced against systemic disease status and operative risk.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Cardiac Metastasis Common questions (FAQ)<\/h2>\n\n\n\n<p><strong>Q: Does Cardiac Metastasis cause chest pain?<\/strong><br\/>\nIt can, but chest pain is not specific. Pain may reflect pericardial irritation (pericarditis-like), myocardial involvement, or unrelated causes such as pulmonary embolism or coronary disease. Clinical context and testing are needed to interpret symptoms.<\/p>\n\n\n\n<p><strong>Q: Is Cardiac Metastasis usually an emergency?<\/strong><br\/>\nNot always. It becomes urgent when it causes hemodynamic compromise (for example, cardiac tamponade), significant arrhythmias, or obstructive physiology. Many cases are detected incidentally during cancer staging and are evaluated in a planned manner.<\/p>\n\n\n\n<p><strong>Q: What tests commonly detect Cardiac Metastasis?<\/strong><br\/>\nTransthoracic echocardiography (TTE) is often the first test to evaluate function and pericardial effusion. Cardiac MRI and CT can provide more detailed anatomy and tissue characterization, and PET may help in staging contexts. The optimal test sequence varies by clinician and case.<\/p>\n\n\n\n<p><strong>Q: Does diagnosing Cardiac Metastasis require a biopsy?<\/strong><br\/>\nNot always. Diagnosis is frequently made using imaging findings plus the overall cancer context, especially when tissue sampling would not change management or carries high risk. Biopsy or cytology is considered when confirmation would meaningfully alter treatment decisions.<\/p>\n\n\n\n<p><strong>Q: Are procedures like pericardiocentesis painful, and is anesthesia used?<\/strong><br\/>\nDiscomfort varies, and local anesthesia is commonly used; sedation practices vary by institution and patient stability. The main goal is safe relief of pressure and stabilization when tamponade physiology or symptomatic effusion is present. Details depend on urgency and setting.<\/p>\n\n\n\n<p><strong>Q: What is the typical cost range for evaluating or treating Cardiac Metastasis?<\/strong><br\/>\nCosts vary widely by country, insurance coverage, hospital setting, imaging modality (echo vs MRI vs PET), and whether a procedure or ICU-level care is required. There is no single typical number that applies across systems. Billing complexity also increases when multidisciplinary care is involved.<\/p>\n\n\n\n<p><strong>Q: How long do results \u201clast\u201d after draining a malignant pericardial effusion?<\/strong><br\/>\nDrainage can provide immediate hemodynamic improvement, but recurrence risk depends on the underlying malignancy and ongoing treatment response. Some patients have durable control, while others experience re-accumulation requiring repeat management. Timing is highly variable by clinician and case.<\/p>\n\n\n\n<p><strong>Q: Is Cardiac Metastasis considered \u201csafe\u201d to treat with heart procedures or surgery?<\/strong><br\/>\nSafety depends on the patient\u2019s hemodynamics, blood counts, anticoagulation status, tumor location, and overall cancer burden. Procedures can be lifesaving in specific scenarios (such as tamponade), but they also carry risks. Decisions are individualized and multidisciplinary.<\/p>\n\n\n\n<p><strong>Q: Are there activity restrictions after a diagnosis of Cardiac Metastasis?<\/strong><br\/>\nRestrictions depend on symptoms, hemodynamic status, arrhythmia burden, and whether a procedure was performed. Some patients maintain usual activity, while others require modified exertion due to dyspnea, dizziness, or treatment side effects. Guidance varies by clinician and case.<\/p>\n\n\n\n<p><strong>Q: How often is follow-up imaging needed?<\/strong><br\/>\nThere is no universal schedule. Follow-up is often driven by symptoms, prior effusion recurrence, and the oncology treatment plan, with echocardiography used when clinical changes occur or when monitoring known effusions. Monitoring intervals vary by clinician and case.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cardiac Metastasis means cancer spread to the heart or pericardium from a tumor that started elsewhere in the body.

It is commonly identified using echocardiography, cardiac magnetic resonance imaging (cardiac MRI), computed tomography (CT), or positron emission tomography (PET).","og_url":"https:\/\/www.bestheartsurgery.com\/blog\/cardiac-metastasis-definition-clinical-significance-and-overview\/","og_site_name":"Best Heart Surgery Hospitals","article_published_time":"2026-02-28T14:44:56+00:00","author":"drheartcare","twitter_card":"summary_large_image","twitter_misc":{"Written by":"drheartcare","Est. reading time":"12 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/www.bestheartsurgery.com\/blog\/cardiac-metastasis-definition-clinical-significance-and-overview\/","url":"https:\/\/www.bestheartsurgery.com\/blog\/cardiac-metastasis-definition-clinical-significance-and-overview\/","name":"Cardiac Metastasis: Definition, Clinical Significance, and Overview - Best Heart Surgery Hospitals","isPartOf":{"@id":"https:\/\/www.bestheartsurgery.com\/blog\/#website"},"datePublished":"2026-02-28T14:44:56+00:00","author":{"@id":"https:\/\/www.bestheartsurgery.com\/blog\/#\/schema\/person\/0065b6c91e674af8926b928d5d76df32"},"breadcrumb":{"@id":"https:\/\/www.bestheartsurgery.com\/blog\/cardiac-metastasis-definition-clinical-significance-and-overview\/#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.bestheartsurgery.com\/blog\/cardiac-metastasis-definition-clinical-significance-and-overview\/"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/www.bestheartsurgery.com\/blog\/cardiac-metastasis-definition-clinical-significance-and-overview\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/www.bestheartsurgery.com\/blog\/"},{"@type":"ListItem","position":2,"name":"Cardiac Metastasis: Definition, Clinical Significance, and Overview"}]},{"@type":"WebSite","@id":"https:\/\/www.bestheartsurgery.com\/blog\/#website","url":"https:\/\/www.bestheartsurgery.com\/blog\/","name":"My blog","description":"Explore the World\u2019s Leading Heart Surgery Centers","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/www.bestheartsurgery.com\/blog\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"},{"@type":"Person","@id":"https:\/\/www.bestheartsurgery.com\/blog\/#\/schema\/person\/0065b6c91e674af8926b928d5d76df32","name":"drheartcare","image":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/www.bestheartsurgery.com\/blog\/#\/schema\/person\/image\/","url":"https:\/\/secure.gravatar.com\/avatar\/69f139135385119c6994f2674e12c1e787be7319fe3ad3f5cf22c1cc47924732?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/69f139135385119c6994f2674e12c1e787be7319fe3ad3f5cf22c1cc47924732?s=96&d=mm&r=g","caption":"drheartcare"},"url":"https:\/\/www.bestheartsurgery.com\/blog\/author\/drheartcare\/"}]}},"_links":{"self":[{"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/posts\/2740","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/users\/10"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/comments?post=2740"}],"version-history":[{"count":0,"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/posts\/2740\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/media?parent=2740"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/categories?post=2740"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bestheartsurgery.com\/blog\/wp-json\/wp\/v2\/tags?post=2740"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
