Background: This study aims to present the mid-term results of the right ventricular outflow tract reconstruction with creation of pulmonary neosinus using pericardial patching.

Methods: Thirty three patients who underwent neosinus creation with pericardial patching due to the right ventricular outflow tract stenosis in our clinic between January 2000 and December 2012 were retrospectively analyzed. The mean follow-up was 4.7 years (range, 1 to 10 years) postoperatively for 28 patients as assessed by echocardiographic findings.

Results: The mean duration of cardiopulmonary bypass and cross-clamp were 112.8±23 and 66.9±9.4 min, respectively. Postoperatively three patients required inotropic support in the intensive care unit. One patient who was operated for Fallot’s tetralogy died due to pneumonia and sepsis following reintubation on postoperative day three. The remaining patients were discharged after an average duration of 8.1±1 days. No patients required reoperation during the follow-up. Twenty-five patients were in New York Heart Association (NYHA) Functional Classification class 1, while three were in NHYA class 2. Echocardiographic examination showed grade 2 pulmonary insufficiency in one patient and grade 1 in six patients with a mean gradient of 21±3 mmHg.

Conclusion: Our study findings suggest that creation of pulmonary neosinus with pericardial patching is a safe surgical technique with a lower perioperative mortality rate. The mid-term results of this technique are encouraging, which can be considered as an alternative treatment modality for the right ventricular outflow tract reconstruction.
