Transcatheter Valve (TCV) Certification Overview

Video Summary

Lesson 2 of ACC's Transcatheter Valve Certification Overview Course explains valvular heart disease. The heart has four chambers and four valves that control blood flow. Valvular heart disease occurs when a valve is damaged or diseased. The most commonly affected valve is the aortic valve. Valve stenosis is when the valve opening is narrowed, reducing the heart's ability to pump blood. Mitral valve prolapse occurs when the valve leaflets do not close smoothly. Mitral regurgitation is when blood leaks backward through the valve. Transcatheter valve therapies aim to treat valve stenosis and mitral valve regurgitation. Risk factors for heart valve disease include high cholesterol, hypertension, and diabetes. Symptoms include dizziness, fatigue, trouble breathing, chest pain, swollen legs, and decreased appetite. Many cases of valvular heart disease are underdiagnosed and diagnosed too late.
