A Health Tracking Application Leads to an Avid Cyclist Being Diagnosed With ALCAPA at 52 Years Old, Warranting a...

We report a 52-year-old avid cyclist who presented with atrial fibrillation and severe mitral regurgitation, initially detected by a wearable health tracking device. Workup incidentally revealed anomalous left coronary artery from the pulmonary artery without ostial stenosis or pulmonary hypertension, leaving the mechanism of decades-long compensation unclear. He underwent a successful anomalous left coronary artery from the pulmonary artery repair using a modified Takeuchi procedure, concurrent mitral valve repair, maze procedure, and left atrial appendage clipping. At 9 months postoperatively, he has fully recovered and resumed cycling, with stable echocardiographic findings.
