Abstract:
This is the first report of a resuscitated adult with left main coronary artery ostial atresia (LMCAOA), with long-term follow-up for 10 years. A 57-year-old woman with untreated Graves' disease presented with resuscitated cardiac arrest, and her computed tomography coronary angiography showed a string-like left main without significant atherosclerosis, which led to the diagnosis of LMCAOA. Noninvasive and invasive testing revealed extensive myocardial ischemia because of LMCAOA with concomitant coronary spasm. After successful revascularization with coronary artery bypass grafting, the patient has remained stable for 10 years, which highlights this treatment as being highly effective and durable in patients with LMCAOA and cardiac arrest.
