RESUMEN
Circumflex aortic arch is a rare vascular ring anomaly, which is often associated with tracheobronchomalacia. Aortic uncrossing is the definitive repair of this condition, which is a major high-risk operation; therefore, it is not suitable for small patients such as newborn infants or individuals who have severe comorbidities. We present a case of the circumflex aortic arch with tracheobronchomalacia in a 2.7-kg infant who underwent successful innovative combined surgery of the airway and the aorta.

We repaired secundum atrial septal defect in 135 consecutive patients from February 2003 to December 2010. There were 98 females and 37 males, with a mean age of 22.92 ± 17.46 years (range, 3-55 years). To prevent myocardial dysfunction and systemic embolism caused by the conventional technique, the operation was performed with a beating heart under cardiopulmonary bypass in 63 cases, and compared the data retrospectively with cases treated under aortic crossclamping, to determine the safety of the beating-heart technique and to evaluate risk factors for embolism in stroke patients. Patient age and size of defect were similar in both groups. There was no death and no residual shunt in either group. The mean cardiopulmonary bypass time was 36.84 ± 9.8 min in the beating-heart group and 43.13 ± 16.7 min in the crossclamp group. The ejection fraction and the incidence of postoperative arrhythmia were similar in both groups. There were no differences in blood products transfused, intensive care unit stay, hospital stay, or perioperative morbidity. In our experience, the results of the beating-heart technique were not different from the conventional technique.
