ObjectiveTo study the in-hospital outcome of adult patients who had undergone surgical
repair for Tetralogy of Fallot.MethodsA retrospective descriptive study was conducted at the Punjab Institute of
Cardiology searching the hospital records. All those adult patients who had
undergone repair for Tetralogy of Fallot from January 2012 to December 2014
were included in the study. All the patients were operated by the same
surgical team. Patients who underwent primary repair as well as those with
previous palliative procedures were included in the study. Thirty days
outcome was studied by recording variables from the database. Data was
analysed using Statistical Package for Social Sciences version 16.ResultsA total of 80 patients was included in the study, in which there were 48
(60%) male patients and 32 (40%) female patients. Mean age was
21±0.21 years. Those with previous palliation were 15 (18.75%). The
associated problems observed were: atrial septal defect 27 (33.75%), right
aortic arch 30 (37.5%), patent ductus arteriosus 6 (7.5%) and double outlet
right ventricle 3 (3.75%). In-hospital mortality recorded was 7 (8%).
Postoperative complications encountered were low cardiac output syndrome 9
(11.25%), pleural effusion requiring tapping 3 (3.75%), reoperation for
bleeding 3 (3.8%), pulmonary regurgitation (moderate to severe) 20 (25%)
which occurred in the transannular patch group only and atrial arrhythmia 4
(5%).ConclusionA large number of adult patients are still operated for tetralogy of Fallot
in Pakistan. With increasing experience in the technique the mortality and
morbidity is comparable to international literature.
