Which are the risks in a fallot correction surgery?

Tetralogy of Fallot: The answer depends on the type of operation. Typically tof surgery involves ventricular septal defect closure, right ventricular muscle bundle division/resection, and relief of any pulmonary valve stenosis (with a transannular patch or right ventricle to pulmonary artery conduit). Risks of the surgery include residual vsd, pulmonary stenosis, pulmonary insufficiency, and ventricular dysfunction.

Early and late: Potential early risks: arrhythmia, residula shunt across vsd, residual narrowing at the pulmonary valve or below it, bleeding and infection. Late risks involved arrhythmia, right ventricular conduction and dilatation causing right heart failure.
