Transesophageal echocardiographic evaluation of perioperative coronary sinus trauma

Retrograde cardioplegia is relatively safe, with a rate of coronary sinus rupture of 0.6%. With the advent of perioperative transesophageal echocardiography, it is now possible to detect and evaluate the extent of damage consequent to the use of retrograde cardioplegia and better formulate an intraoperative course of action. The evolution of these lesions can also be monitored by transesophageal echocardiography during the postoperative period.
