Anomalous origin of right coronary artery causing myocardial ischemia in a young patient

Abstract

Anomalous right coronary artery from left coronary sinus can have dynamic narrowing and kinking causing symptoms of myocardial ischemia and sudden cardiac death. Surgical repair of the anomaly is required in the symptomatic patient because of risk of ischemia or ventricular arrhythmia. Asymptomatic incidentally diagnosed low-risk patients can be closely followed up with exercise restriction as per present guideline.

Transient numerical simulation of the right coronary artery originating from the left sinus and the effect of its acute take-off angle on hemodynamics

“…AORL is a rare congenital anomaly that can lead to myocardial ischemia and arrhythmia, increasing the risk of sudden cardiac death (41). Risk stratification and management can reduce the risk of ischemia in patients with AORL (41).…”

“…AORL is a rare congenital anomaly that can lead to myocardial ischemia and arrhythmia, increasing the risk of sudden cardiac death (41). Risk stratification and management can reduce the risk of ischemia in patients with AORL (41). The risk of sudden death depends on several anatomical features: an intramural course, a slit-like orifice, and an acute take-off angle (8,42).…”

Approaches to the treatment of the premature ventricular contractions in a young patient with anomalous origin of the right coronary artery from the left sinus of Valsalva

“…Описаны различные типы хирургических методов восстановления кровотока обедненного русла коронарной артерии, которые включают в себя шунтирование, а также прямую реимплантацию ПКА в правый коронарный синус. Исследования показывают, что методы являются безопасными и демонстрируют хорошие среднеи долгосрочные результаты в отношении продолжительности и качества жизни пациентов [7,8].…”

Origin of Right Coronary Artery (RCA): A Multidetector Computed Tomography (MDCT) Coronary Angiographic (CA) Study in North India

“…Anomalous artery should be surgically repaired in the symptomatic patients because of risk of ischemia or ventricular arrhythmia and a close follow up is required in asymptomatic patients with exercise restriction as per present guideline. [44] Targeted patients for treatment are those whose anomalous artery is dominant, whose anomalous artery is having proximal intramural course and those who become symptomatic before 35 years of age. [41] Cheatham JP, et al reported origin of RCA from descending thoracic aorta and found atypical and elastotic changes and wall thickening in this RCA.…”
