Ventricular Septal Defects (VSDs)

A VSD is a hole in the wall that separates the two lower chambers of the heart. There are many different kinds of VSDs; some require early surgical repair, while others only require follow-up observation. In rare cases, large uncorrected VSDs can lead to the development of pulmonary hypertension and low oxygen levels in the blood. Follow-up in adulthood is important to screen for residual defects and complications that can result from unrepaired defects.
