Abstract:
Ventricular Septal Defect (VSD) is the most frequent cardiovascular anomaly. VSD causes pulmonary hypertension through stenotic changes in the pulmonary vasculature, and this progress depends on the size of defect and associated cardiovascular anomalies. Since surgical repair has been performed in childhood for patients without a tendency toward spontaneous closure of VSD, operations in elderly patients, especially those aged over 40, are rare. We report an elderly patient with VSD complicated with severe pulmonary hypertension who underwent surgical repair. A 66-year-old man was admitted to our hospital because of general fatigue, chest oppression and palpitations. The pulmonary to systemic pressure ratio was 0.66. The oxygen saturation stepped up at the right ventricle level. The pulmonary to systemic blood flow ratio was 2.9, shunt ratio was 71% and resistance ratio was 0.12. The VSD was 18mm in diameter at the perimembranous trabecula and was closed with a Dacron patch through a right atrium incision. The lung biopsy specimen revealed little occlusive pulmonary vascular disease, Grade I according to the Heath-Edwards criteria. The patient had an uneventful recovery.
