Study Notes
Ventricular Septal Defect (VSD)
- Failure of the interventricular septum to close properly during fetal development
- Allows blood to shunt across the interventricular septum
- Usually between the ventricles
- Can be asymptomatic or cause heart failure
- May be associated with aortic valve prolapse and aortic regurgitation
Types of VSDs
- Trabecular or muscular septal VSD: Located between the bodies of the left ventricle and the right ventricle
- Inlet septal VSD: Bordered by the mitral valve, tricuspid valve, and muscle; often associated with an atrioventricular septal defect
- Outlet septal VSD: Located between the left ventricular outflow tract and right ventricular outflow tract
- Membranous septal or perimembranous septal VSD: Bordered by the tricuspid valve, aortic valve, and muscle; most common type
- Malalignment septal VSD: Occurs when the two portions of the interventricular septum have failed to align properly during development
VSD and Associated Conditions
- Pulmonary hypertension: Increased pulmonary vascular resistance
- Eisenmenger’s syndrome: Right-to-left shunt leading to systemic cyanosis
- Mitral regurgitation: Common in patients with VSD
VSD on Echocardiogram
- Echo-free space along the interventricular septum
- Turbulent color flow Doppler (CFD) travels through the VSD between the left ventricle and right ventricle
- Document VSD location, size, velocity, and direction
- Calculate the Qp/Qs shunt ratio
- Evaluate associated findings (left ventricular volume overload, pulmonary hypertension, aortic valve prolapse, aortic insufficiency)
Endocardial Cushion Defect (ECD)
- Involves a combination of congenital heart anomalies that create a butterfly appearance
- Hole in the center of the heart where the upper chambers meet the lower chambers
- Allows oxygenated blood to mix with deoxygenated blood
- Common valve in place of the mitral valve and tricuspid valve
- Frequently associated with Trisomy 21 (Down Syndrome)
- Typically presents in-utero or anytime from birth to several months
Cleft Mitral Valve
- Slit-like hole or division of the mitral valve leaflets
- Commonly affects the anterior mitral valve leaflet
- Isolated cleft posterior leaflet is extremely rare
- Evaluate the valve anatomy and degree of cleft edge fibrosis and retraction
- Regurgitation is common and should be addressed
- Surgical repair is typically required
- Associated cardiac lesions - Atrial Septal Defect (Primum)
