Closed transventricular pulmonary valvotomy in infants.
Journal of Thoracic and Cardiovascular Surgery 1982 August
In an effort to reassess the efficacy of closed transventricular valvotomy in infants with severe pulmonary stenosis, we reviewed 24 consecutive patients who underwent closed transventricular valvotomy. The age range was 1 day to 11 months (median 53 days), with 10 patients under 1 month and 21 under 6 months of age. The weight range was 2.6 to 9.4 kg (median 4.1 kg). The long-term results were assessed by comparing the postoperative to the preoperative clinical and hemodynamic data. The 20 survivors were followed up for 3 to 133 months (median 54 months). All were asymptomatic upon the last follow-up visit, and their electrocardiograms and chest x-ray films were normal or improved. In 12 patients who had cardiac catheterization 7 to 85 months (median 50 months) after operation, the range for the right ventricular-to-left ventricular, or systemic arterial, peak systolic pressure ratio (RV:LV) was 0.97 to 1.7 preoperatively (mean 1.31) and 0.22 to 0.94 postoperatively (mean 0.42) (p less than 0.001). In order to assess the significance of the RV size for the surgical survival, we measured the preoperative RV end-diastolic volume (RVEDV) in 17 patients. Twelve patients had a normal or enlarged RV and all survived the operation, whereas two of the five patients with an RVEDV more than 2 SD below the normal mean (RVEDV less than 23 ml/m2) died postoperatively (p = 0.075). We conclude that closed transventricular valvotomy can be done successfully in infants with severe pulmonary stenosis and an RV which is not small. The risk of cardiopulmonary bypass is avoided and good long-term results can be obtained. We also present evidence that a small RV (RVEDV less than 23 ml/m2) is a potentially important predictor of the surgical risk.
