Longstanding Coronary artery to coronary sinus bilateral fistulae can induce heart failure symptoms but can be surgically closed adequately with good clinical outcome. See Commentary page e205. A 58-year-old woman with a history of giant coronary artery to coronary sinus fistula, status after an attempted surgical closure 11 years ago, presented with worsening dyspnea and dilated cardiomyopathy. Diagnostic workup with cardiac catheterization and computed tomographic angiography revealed a high output circulation with persistent right and left coronary fistulae (Figure 1, Videos 1 and 2). Reoperation was undertaken with right axillary and femoral venous peripheral cannulation for cardiopulmonary bypass because of the retrosternal, massively dilated coronary fistulae. Cardioplegic arrest was achieved using antegrade cardioplegia that was delivered at very high flow with a finger placed on the coronary sinus to prevent it from flowing directly into the coronary sinus circulation as well as retrograde cardioplegia. Next, the fistula was addressed; the dilated right coronary artery was opened longitudinally near the fistulous connection and the right atrium was entered and a probe was inserted through the coronary sinus into the common opening to the right and left coronary fistulae. The opening was approached from the epicardial surface and was oversewn using 4-0 prolene. Furthermore, the terminal aspects of the right and left fistula near the coronary sinus were dissected, encircled, and tied off using number 4 silk suture. At the end of the procedure the mixed venous saturation of the patient came down to 82% from 99%. The patient recovered well and her heart failure symptoms resolved.Video 2LCx angiogram.

Commentary: The challenging management of coronary artery fistulasThe Journal of Thoracic and Cardiovascular SurgeryVol. 157Issue 4PreviewAsymptomatic small coronary artery fistulas are quite common malformations and can be considered normal.1 Large fistulas, however, create a significant shunt and can lead to heart failure if left untreated. The incidence of coronary artery to coronary sinus fistulas is very low, and publications on surgical treatment are limited to case reports.2,3 This particular subtype is also anatomically challenging, as these fistulas tend to have a very tortuous course and show significant enlargement of the affected vessels.
