A 47-year-old male with arterial hypertension and with unroofed coronary sinus syndrome diagnosed two years before the surgery on transesophageal echocardiography (TEE) (Figures 1, 2) and cardiac computed tomography (Figures 3A,B) was referred to our clinic for repair. In agreement with the TEE findings, the unroofed CS was spotted in proximity to the posterior leaflet section (P3) of the mitral valve, circular with an area of about 15 mm x 15 mm (Figures 4A,B and Supplementary Video 1).
Preoperative transesophageal echocardiography. Preoperative transesophageal echocardiography images of the unroofed coronary sinus. Direct communication between the coronary sinus and left atrium. CS, coronary sinus; LA, left atrium; RA, right atrium; URCS, unroofed coronary sinus.

Preoperative cardiac computed tomography. Computed tomography showed extensive communication between the coronary sinus and left atrium caused by partial absence of the roof of the coronary sinus. The absence of the coronary sinus roof and communication between CS and the left atrium. (A) Modified four-chamber projection. (B) Modified short-axis projection. CS, coronary sinus; LA, left atrium; RA, right atrium; URCS, unroofed coronary sinus.

Intraoperative findings of the unroofed coronary sinus. Intraoperative findings showed (A) the unroofed portion of the coronary sinus at the left atrial side close to segment P3 of the posterior mitral leaflet. (B) Repair of the coronary sinus with direct continuous suture. A2, A2 segment of anterior mitral leaflet; A3, A3 segment of anterior mitral leaflet; P2, P2 segment of posterior mitral leaflet; CS, coronary sinus.
