Abstract

Between January 1984, and July, 1985, 26 consecutive symptomatic patients with tetralogy of Fallout underwent a primary radical repair at department of Thoracic and Cardiovascular Surgery, Chonnam Medical University Hospital in KwangJu, Korea. Eighteen of 26 patients were survived in hospital after radical correction. In the thirteen patients, we performed postoperative cardiac catheterization and angiography in survivor after 4 weeks period.
The results were compared with preoperative diagnostic studies. Three of patients who underwent non-transannular patch enlargement were still remained moderate to severe right ventricular outflow tract obstruction, but none of patients who underwent transannular patch enlargement. All of patients were postoperatively normal right ventricular end diastolic pressure except 2 patients a little increased (l0mmHg).
The postoperative right ventricular-left ventricular systolic pressure ratio (PRV/ LV) more than 0.75 was related to outflow tract reconstructive procedures. ; 3 of 8 patients (38%) in non-transannular patch enlargement were occurred, but one of 5 patients in transannular patch enlargement. Three of 13 patients were occurred moderate to severe pulmonary regurgitation and residual ventricular septal defect, especially pulmonary regurgitation was related to outflow tract reconstructive procedures. ; 3 of 5 patients who underwent transannular patch enlargement were occurred, but none of patients who underwent non-transannular patch enlargement.
We determined that surgeon should require accurate diagnosis and meticulous technique to overcome the surgical pitfalls, residual ventricular sepal defect, residual pulmonary stances, significant pulmonary regurgitation.
