Systemic Hypertension is persistently elevated arterial blood pressure in the systemic circulation. It is a cardiovascular condition defined and tracked using blood pressure measurements (systolic and diastolic). It is commonly discussed in primary care, emergency medicine, cardiology, nephrology, and perioperative medicine. It matters because it is both a disease entity and a major risk factor for atherosclerotic cardiovascular disease and end-organ damage.

Pulmonary Hypertension (PH) is abnormally elevated pressure in the pulmonary circulation. It is a cardiopulmonary disease concept that links lung vascular physiology to right heart function. It is most commonly discussed in cardiology, pulmonology, critical care, and perioperative medicine. It is identified through clinical evaluation and confirmed with hemodynamic testing.

Tricuspid Regurgitation is backward leakage of blood from the right ventricle into the right atrium during systole. It is a valvular heart disease concept grounded in cardiac anatomy and hemodynamics. It is most commonly discussed in echocardiography reports and bedside cardiovascular assessment. It is clinically relevant in right-sided heart failure, pulmonary hypertension, and perioperative cardiology.

Mitral Regurgitation is leakage of blood backward across the mitral valve from the left ventricle into the left atrium during systole. It is a valvular heart disease rooted in cardiac anatomy and hemodynamics. It is commonly identified on cardiac auscultation and confirmed with echocardiography. It is frequently discussed in heart failure, ischemic heart disease, and cardiothoracic surgery decision-making.

Mitral Stenosis is a narrowing of the mitral valve opening that limits blood flow from the left atrium to the left ventricle. It is a valvular heart disease rooted in cardiac anatomy and hemodynamics (blood-flow mechanics). It is commonly identified and graded using transthoracic echocardiography (TTE) with Doppler ultrasound. It is frequently discussed in cardiology, emergency medicine, anesthesia, and cardiothoracic surgery because it can drive symptoms, arrhythmias, and pulmonary complications.

Aortic Regurgitation is a heart valve disorder in which blood leaks backward from the aorta into the left ventricle during diastole. It is a problem of cardiac anatomy and valve function, centered on the aortic valve and the aortic root. Clinicians discuss it in bedside assessment (murmurs) and in cardiovascular imaging, especially echocardiography. It is commonly referenced when evaluating dyspnea, heart failure physiology, and aortic disease.

Aortic Stenosis is narrowing of the aortic valve opening that obstructs blood flow from the left ventricle to the aorta. It is a valvular heart disease discussed in cardiovascular anatomy, physiology, and pathology. It is commonly assessed with physical examination and echocardiography. It is a frequent reason for long-term follow-up and, in selected cases, valve intervention.

Coarctation of Aorta is a congenital narrowing of the aorta. It is an anatomic cardiovascular disease that alters normal blood flow and pressure. It is commonly discussed in pediatric cardiology, adult congenital heart disease, and emergency care. It is assessed with physical examination and cardiovascular imaging, and it may be treated with catheter-based or surgical approaches.

Tetralogy of Fallot is a cyanotic congenital heart disease defined by four related structural heart defects. It is primarily an anatomic and physiologic diagnosis discussed in pediatric cardiology, adult congenital heart disease, and cardiothoracic surgery. It commonly presents in infancy but has lifelong implications after repair. It is frequently evaluated with echocardiography, electrocardiography (ECG), and cross-sectional imaging.
