“…Historically, TEE was complementary to classic left heart catheterization to assess coronary artery anomalies [5]. The coronary artery's anomalous origin prevalence depends on diagnostic modality: 0.05-0.1% in ICA [6], 0.15% in Echo, 0.82-1% in CT angiography, and 0.70% in MRA [7]. The prevalence of inter-arterial anomalous left coronary artery (ALCA) was 0.03%, and inter-arterial anomalous right coronary artery (ARCA) was 0.23%.…”

“…Tachyarrhythmia can lead to reversible cardiomyopathy caused by ventricular dilation and systolic dysfunction. The pathophysiology of tachycardia-induced cardiomyopathy is the depletion of ATP, decreased myocardial blood flow, and increased oxidative stress, causing loss of fibrillary function and leading to ventricular dysfunction [7]. Exaggerated ACE production in response to tachycardia increases angiotensin-2, causes myocyte elongation, left ventricular enlargement, and changes the wall stress [17].…”

“…Conservative medical/observation treatment includes beta-blockers and restriction of severe physical exertion. For surgical options, symptomatic patients with syncope, angina, ventricular arrhythmia, and evidence of ischemia on provocative testing are warranted [7]. In the case of inter-arterial anomalous aortic origin of the left coronary artery (AAOLCA), even if they are asymptomatic, it is often referred to for surgical intervention due to the increased risk of SCD with this anomaly.…”

The anomalous origin of the coronary artery is a relatively uncommon condition with a variant incidence depending on the modality of the imaging techniques such as transesophageal echocardiography (TEE), computed tomography angiography (CTA), magnetic resonance angiography (MRA), or invasive coronary angiography (ICA). The importance of diagnosing ectopic coronary artery origin comes from its possible relation to sudden cardiac death (SCD) cases in young populations. The anomalous origin of the coronary artery could cause myocardial ischemia and fibrosis; this would, in turn, increase the chances of fatal ventricular arrhythmias. In this report, we present a 40-year-old male, incidentally found to have persistent tachycardia and a gradually decreasing left ventricular ejection fraction (LVEF). He denied any symptoms or changes in his baseline, unlimited, functional capacity. However, his records were remarkable for persistent tachycardia over more than six months, raising concerns about tachyarrhythmia-induced cardiomyopathy related to his anatomical variations. We also discussed the guideline-directed therapeutic option for the abnormal origin of the coronary artery as per current guidelines.
