Complete Atrioventricular Canal and Tetralogy of Fallot: Surgical Considerations

Complete Atrioventricular Septal Defect Associated With Tetralogy of Fallot

“…The clinical and anatomical features of our cases did not significantly differ from those in other reports. 3,4,14,16 All the patients reported here had Down syndrome and a free-floating superior bridging leaflet (Rastelli Type C). On ECG, 8 patients revealed superior axis, and 2 patients showed inferior axis deviation.…”

Surgical Management of Complete Atrioventricular Septal Defect with Tetralogy of Fallot

“…As a result of this hemodynamic abnor mality, both the tricuspid and the pulmonary valve are affected, greatly increasing the risk of heart failure. 3,16) An overall evaluation of the cardiac anomaly is impor tant to surgical strategy. With respect to TOF, we are mainly concerned about the growth of the pulmonary artery and the distribution of the coronary artery.…”

Repair of complete atrioventricular septal defect with tetralogy of Fallot

“…Significant regurgitation of the LAVV can elevate the pulmonary artery pressure and increase the pulmonary valve insufficiency, particularly if a transannular patch is present. These factors in combination with technical challenges result in a greater risk for repair of CAVSD-TOF than the risk for either lesion alone (19).…”

“…The RVOTO in CAVSD-TOF should be relieved by employing a right ventriculotomy and RVOT patch enlargement, or when a small pulmonary valve is present, a transannular approach. Some authors have advocated the avoidance of a transannular incision preferring a valve conduit over a transannular patch (25) others have not found a transannular patch to be detrimental to short or long-term results (19). If a transannular patch is employed a complete relief of RVOTO would appear to be essential (13).…”
