Abstract
BACKGROUND: An anomalous coronary artery from the opposite sinus of Valsalva may increase sudden death risk in children and young adults, and surgical intervention is often recommended. The impact of this lesion when recognized in the adult and its management are ill defined. METHODS AND RESULTS: We reviewed 210 700 cardiac catheterizations performed over a 35-year period at a single institution and identified 301 adults with an anomalous coronary artery from the opposite sinus of Valsalva, either anomalous right coronary artery from the left cusp or anomalous left main coronary artery from the right cusp. Patients were stratified by the pathway of the anomalous artery and the chosen treatment. Among the 301 patients with anomalous coronary artery from the opposite sinus of Valsalva (0.14% of the cohort), 79% had anomalous right coronary artery from the left cusp, and 18% had an interarterial course (IAC). Patients with IAC were younger (52±13 versus 59±13 years; P=0.001) and more likely to undergo surgical intervention (52% versus 27%; P<0.001), but mortality was not increased with IAC. Among the 54 patients with IAC, 28 underwent surgical repair with no perioperative deaths. Patients evaluated since 2000 were significantly more likely to be referred for surgery (P=0.004). Surgical patients were more likely to have abnormal stress tests (90% versus 43%; P=0.01) and had more extensive atherosclerosis but less diabetes mellitus (0% versus 23%; P=0.01). Long-term survival at 10 years appeared similar in both groups. CONCLUSIONS: In this single-center cohort study of patients with an anomalous coronary artery from the opposite sinus of Valsalva, surgical management appears to have been favored recently. Despite no perioperative mortality, a positive impact on long-term survival was not observed. The impact of surgery in older adults with anomalous coronary arteries arising from the opposite coronary sinus with IAC deserves further study.

Dr. Richard Krasuski is Director of the Adult Congenital Heart Center at Duke University Medical Center, the Director of Hemodynamic Research, and the Medical Director of the CTEPH Program. He is considered a thought leader in the fields of pulmonary hypertension and congenital heart disease. His research focus is in epidemiologic and clinical studies involving patients with pulmonary hypertension and patients with congenital heart disease. He is involved in multiple multicenter studies through the Alliance for Adult Research in Congenital Cardiology (AARCC). He has also helped to develop multiple research databases in these patient populations. He is Co-PI in the upcoming EPIPHANY Study examining the impact of medical and transcatheter interventions on RV-PA coupling in patients with chronic thromboembolic pulmonary hypertension. Over his career he has mentored over 80 students, residents and fellows and has published over 300 peer reviewed publications, book chapters and meeting abstracts. He is also the Chief Editor of Advances in Pulmonary Hypertension and on the editorial boards of several leading medical journals.
