The right ventricular outflow tract (RVOT), also known as the infundibulum or conus arteriosus, is a distinct anatomical and functional entity of the right ventricle. It acts as
Fetal circulation is a highly specialized system designed to optimize oxygen delivery to the developing brain and myocardium while bypassing the non-functional fetal lungs and immature liver. It
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
