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 |
-Tracheobronchomalacia. |
▪ 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) |
