Left Mammary Artery Bypass Grafting Rescued a Patient With Hypoplastic Left Heart Syndrome With Ascending Aorta Obstruction After Norwood Stage I Procedure
A three-month-old boy with hypoplastic left heart syndrome (mitral atresia, aortic atresia) and moderate tricuspid regurgitation developed ascending aorta obstruction two months after a Norwood stage I procedure. An emergent left mammary artery bypass grafting to the ascending aorta and extracorporeal membrane oxygenator support resulted in successful salvage. The patient subsequently underwent a bidirectional Glenn procedure and tricuspid valve repair at the age of five months. Follow-up at an outpatient clinic reveals no electrocardiographic evidence of ischemia, and echocardiography shows recovery of ventricular function.
