Tetralogy of Fallot and absent pulmonary valve (T-APV) is associated with massively dilated pulmonary arteries that cause tracheobronchial compression in the newborn and heart failure and cyanosis in older patients. Corrective operations have been attended by high mortality rates due to pulmonary insufficiency causing right heart failure (RHF) and pulmonary complications. Pulmonic valve insertion (PVI) with complete repair has resulted in improved survival. During the last 5 years, 152 patients with tetralogy were corrected. Of these, 10 patients (ages 51 days to 34 years) had absent pulmonary valve. One patient (age 51 days) presented with severe RHF and pulmonary insufficiency and 9 patients presented with mild RHF and cyanosis. Chest roentgenograms showed increased cardiothoracic ratio and pulmonary prominence in all. Arteriography revealed massively enlarged pulmonary arteries with a mean ratio of 2:1 for size of pulmonary artery to aorta. Associated pulmonic stenosis and insufficiency was present in all. Seven patients underwent closure of ventricular septal defect (VSD) and PVI. Of these, 3 had PVI (2 tissue and 1 prosthetic) with outflow patch and 4 had right ventricle to pulmonary artery (RV-PA) tissue valved conduits. Two patients had repair without PVI, and 1 had repair with a monocusp pericardial valve patch. Nine patients have done well with no episodes of thromboembolism or infection. Death occurred in a 51-day-old infant who had VSD closure and relief of pulmonic stenosis. Pulmonary valve insertion seems to be indicated in these patients because it lowers peak pulmonary artery pressure and, thus, reduces compression effects on the trachea and bronchi. When PVI was used, RHF did not occur post-operatively.
