Abstract:
To analyze the mid-long-term outcomes of surgical balloon valvuloplasty (SBV) for right ventricular decompression in the treatment of pulmonary atresia with intact ventricular septum (PA/IVS). Methods Clinical data of consecutive 91 patients who were diagnosed with PA/IVS and underwent SBV in our institution from January 2005 to December 2017 were retrospectively analyzed, including 52 (57.1%) males and 39 (42.9%) females. The median age was 3 months (1 d, 24 months) and the median weight was 4.1 (2.5, 12.0) kg. Results The SBV was performed in all patients, and 62 of whom received other simultaneous surgeries, including ligation of patent ductus arteriosus (PDA, 33 patients), ligation of PDA with modified Blalock-Taussig shunt (23 patients), ligation of PDA with bidirectional Glenn shunt (6 patients). There was no early postoperative death. The median follow-up time was 8.8 (2.5, 13.4) years, 4 patients were lost. There were 7 (8.0%) deaths and 1 (1.1%) patient with a re-SBV for pulmonary stenosis. The one and a half ventricular repair was performed in 5 (5.7%) patients and Fontan procedure in 2 (2.3%) patients. In addition, the mean Z-value of tricuspid valve annulus was −1.7±1.5, which was significant bigger than that before the operation (t=5.587, P<0.001). Conclusion SBV via right ventricular outflow tract for right ventricular decompression in the treatment of PA/IVS is safe and reliable. The majority of patients can receive biventricular repair instead of single ventricular palliation by SBV with individually customized shunt.
