Percutaneous coronary sinus cannulation guided by transesophageal echocardiography

We investigated whether percutaneous cannulation of the coronary sinus could be accomplished without fluoroscopy using transesophageal echocardiography in patients undergoing minimally invasive cardiac operations. The coronary sinus was cannulated without significant complications using transesophageal echocardiography in 10 of 11 patients (mean, 10.5 minutes). Percutaneous cannulation of the coronary sinus can be accomplished in a safe and efficient manner using transesophageal echocardiography without the need for fluoroscopy.
