Surgical repair for an anomalous left coronary artery from the pulmonary artery and mitral regurgitation in a symptomatic adult woman.

A 48-year-old woman, who had undergone surgery to treat a patent ductus arteriosus when she was 12 years old, was diagnosed with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and moderate mitral regurgitation during a routine exam. She underwent ALCAPA repair with an intrapulmonary tunnel using a vascular prosthesis and mitral valve repair. She experienced significant symptom improvement and has been free of heart failure symptoms after surgery. Anomalous origin of the left coronary artery from the pulmonary artery is rare but life-threatening, necessitating surgical intervention even in asymptomatic adults. Choosing an appropriate surgical approach is important, considering the patient's age and future intervention potential.
