While Ebola Virus Disease (EVD) is primarily recognized for its profound hemorrhagic complications and systemic shock, direct and indirect cardiovascular involvement is a significant and often fatal component
Here is a comprehensive breakdown of the anatomy and physiology of coronary circulation. I. Anatomy of Coronary Circulation The coronary circulation consists of the blood vessels that supply
Extracorporeal Membrane Oxygenation (ECMO) is a critical, complex intervention in the management of refractory cardiogenic shock and severe respiratory failure. Key Cardiovascular Considerations in VA-ECMO Unlike VV-ECMO, which
Radiofrequency (RF) catheter ablation has evolved from a rescue therapy to a primary strategy in the management of recurrent ventricular tachycardia (VT), particularly for patients with structural heart
Cardiac tamponade is fundamentally a mechanical problem: the accumulation of pericardial fluid under high pressure restricts the heart’s ability to fill during diastole. This creates a state of
Localization of an accessory pathway (AP) relies on analyzing the initial 20–40 milliseconds of the QRS complex — the delta wave. Because this initial deflection represents purely pre-excited
Echocardiographic evaluation is the cornerstone for diagnosing constrictive pericarditis (CP). The fundamental pathophysiology of constriction involves a rigid, non-compliant pericardium that limits total cardiac volume, leading to exaggerated
When a patient presents with a regular or irregular tachycardia and a narrow QRS complex (less than 120 milliseconds), it tells us that ventricular depolarization is occurring via
Arrhythmias represent the leading cause of morbidity, unplanned hospitalization, and death in adults with congenital heart disease (ACHD). Managing them requires shifting focus from simple rate or rhythm
Secondary hypertension refers to an elevated blood pressure caused by an underlying, identifiable, and potentially reversible condition. While long thought to affect only 5% to 10% of patients,
