ABSTRACT
Reconstruction of the aortic arch in type B interruption requires extensive mobilization of the descending aorta and the proximal branches of the arch to perform a tension-free anastomosis. The association of a coexistent type II aortopulmonary window and an aberrant subclavian artery reduces the degree of mobility that can be achieved by dissection alone, and it usually entails sacrifice of the aberrant artery to achieve satisfactory mobilization. We report a novel technique to use the aberrant subclavian artery as autologous tissue in the reconstruction of the aortic arch for repair of type B interruption associated with type II aortopulmonary window.

Exposure of the lateral and inferior surface of the heart during off-pump coronary artery bypass grafting is associated with some degree of cardiac instability during recovery with completion of grafting. Exposure of lateral and posterior surfaces by currently available equipment is difficult in minimally invasive coronary artery bypass grafting (MICABG) owing to limited exposure. We describe an effective variation of often-used technique of pericardial stitch in exposure of cardiac surfaces during MICABG. This technique was used in 24 patients undergoing multivessel MICABG. Deep pericardial sutures were used to manipulate the exposure of cardiac surfaces. Left anterior descending artery was grafted in all 24 cases. Obtuse marginal artery was grafted in 20 cases and posterior descending artery in 12 cases. Average grafts were 2.3 per patient. There was no conversion to median sternotomy. Use of deep pericardial suture is simple technique for exposure of lateral and inferior surface during multivessel MICABG. This offers adequate exposure and operating space for easy maneuverability.
