DOES PRESERVATION OF PULMONARY VALVE THROUGH TRANSATRIAL AND TRANSVENTRICULAR APPROACH IN PRIMARY REPAIR OF TETROLOGY OF FALLOT IMPROVES CLINICAL OUTCOMES: A PILOT STUDY AT AFIC/NIHD

Abstract

Objective: This study evaluates the effect of preserving pulmonary valve in total correction repair for Tetrology of
Fallot in terms of early clinical outcomes.
Study Design: Retrospective observational study.
Place and Duration of Study: Armed Forces Institute of Cardiology and National Institute of Heart Disease, from
Oct 2016 to Jan 2017.
Material and Methods: All 15 cases of classic Tetrology of Fallot (TOF) undergoing total correction by a single
operator were studied for early post operative outcomes.
A total of 15 patients with classic TOF were included in this study. There were 10 (66.7%) males and 5 (33.3%)
females. The age ranged from 2-15 years with a mean age of 6.73 ± 4.2 years.
Total correction for tetrology of Fallot was done through primary repair securing the integrity of the pulmonary
valve. Two of the patients (13.32%) had repair through mono cusp valve made from native pericardium while 2
(13.32%) had Donhl patch to main pulmonary artery and right ventricular outflow tract. Six of all patients
(39.69%) had normal pulmonary valve while 5 patients (33.30%) had open pulmonary valvotomy.
Results: One patient (6.66%) died due to septicemia after having pulmonary valvotomy and MAPCA coiling in
total correction procedure. Bilateral pleural effusion was reported in 4 (26.64%) and 2 patients (13.32%) had
ascites. Superficial wound infection occurred in 4 (26.64%) of the patients.
Conclusion: Pulmonary valve securing approach is a significant factor for total correction complete repair for
tetrology of Fallot.
