Abstract/OtherAbstract:
BACKGROUND: Inferior wall myocardial infarction caused by obstruction of an anomalous-origin right coronary artery (RCA) is a rare angiographic finding; primary angioplasty to an anomalous-origin RCA has never been reported. METHODS: In 185 patients with acute inferior wall myocardial infarction resulting from RCA occlusion who underwent primary angioplasty, eight patients (4.3%) had anomalous-origin RCAs. RESULTS: Coronary angiography showed that all 8 patients had a dominant RCA. Six patients (75%) had an anomalous-origin RCA arising from the anterior aspect of the ascending aorta above the sinotubular line and the other 2 patients (25%) had an anomalous-origin RCA arising from the left sinus of Valsalva with a separate ostium from the left main coronary artery. The standard Judkins right guiding catheter did not offer adequate support in these patients. In the group of 6 patients, an Amplatz guiding catheter offered good support, while a standard Judkins left guiding catheter was adequate in the other 2 patients. Obstruction of the proximal RCA occurred in 6 patients (75%). Successful reperfusion was achieved in 6 patients (75%), resulting in an uneventful clinical course and long-term survival (mean follow-up, 24.9 +/- 16.5 months). Two patients (25%) had unsuccessful reperfusion and died from cardiogenic shock. CONCLUSIONS: In this small series, anomalous-origin RCAs were the dominant artery and predisposed to atherosclerosis at the proximal portions. We suggest that appropriate guide catheter selection and careful manipulation are essential for the success of revascularization. Complete reperfusion results in an excellent clinical and long-term outcome in patients with anomalous-origin RCAs.
