01
Overview
VSD permits communication between the ventricles and usually produces a left-to-right shunt after birth.
02
Clinical Features
Small VSDs may be asymptomatic with a loud murmur. Larger defects can produce tachypnea, poor feeding, recurrent respiratory symptoms, and heart failure.
A harsh pansystolic murmur is characteristic.
03
Investigation
Echocardiography establishes the anatomy and measures shunt effects on chamber size and pulmonary circulation.
04
Management
Small defects may close spontaneously and can be monitored. Significant symptomatic defects may require medical therapy and definitive closure.
05
Clinical Pearls
OSMOND PEARL
Large VSDs often become symptomatic when pulmonary vascular resistance falls after birth.
