ANGIO QUIZ Aberrant Right Coronary Artery arising from Left Coronary Sinus of Valsalva:Confirmation by 64-Slice Computed Tomographic Coronaiy Angiography.

摘要

A middle aged hypertensive male of 65 years admitted for unstable angina, who was found to have significant 75% atherosclerotic stenosis of his aberrant right coronary artery arising from the opposite left coronary sinus of Valsalva (ARCAOS) (Figure 1) and an 80% block of alarge second diagonal branch (D2) emerging from anormalanatomicalleftanteriordescendingcoronary artery (Figure 2). The angina could have been because of the course of anomalous right coronary artery between the aorta and the pulmonary artery (PA) making it vulnerable to the scissoring effect or it could have been because of the atherosclerotic lesion. If the angina is because of scissoring effect, angioplasty will be useless, rather counterproductive because of possibility of stent damage due to its course between pulsating vessels. Keeping In view the recent onset of symptoms, it was felt that angina was due to atherosclerotic lesions.
