Key result
Transcatheter closure using multimodality imaging successfully treated a rare and technically challenging left circumflex to coronary sinus fistula.
Why the study?
Coronary artery fistulae connecting the left circumflex to the coronary sinus are rare, and surgical closure is technically challenging due to location, particularly in high-risk surgical patients.
Case Report (n=1)
Transcatheter closure using multimodality imaging guidance is a feasible alternative to surgery for complex left circumflex to coronary sinus fistulae.
Transcatheter closure may be feasible for rare coronary fistulae in high-risk patients; leaves open need for prospective validation.
Coronary artery fistulae connecting the left circumflex to the coronary sinus are rare. Surgical closure of coronary sinus connections is technically challenging because of the location, especially in high-risk surgical patients. We used multimodality imaging to delineate the drainage site and successfully closed a left circumflex to coronary sinus fistula using a transcatheter closure technique. (Level of Difficulty: Advanced.)
