General Complications

▪ Residual stenosis or regurgitation.

▪ Right ventricular dysfunction: both systolic and diastolic. The latter is more common due to the right ventricle hypertrophy and its poor compliance, particularly if a right ventriculotomy is performed.

Specific Complications

▪ Repair of Fallot’s tetralogy and its variants

-Right ventricular dysfunction.

-Arrhythmias: JET, CHB.

-Pulmonary regurgitation.

-Residual pulmonary stenosis.

-Residual ventricular septal defect.

▪ Repair of absent pulmonary valve syndrome


▪ Repair of pulmonary atresia with intact ventricular septum

-Right ventricular dysfunction.

-Myocardial ischemia (in case of right ventricular dependent coronary circulation).

-Circular shunt: if it is used both systemic to pulmonary fistula type modified Blalock-Taussig shunt and a patch on the right ventricular outflow tract.

-Hypoxia (particularly in the first postoperative hours)
