Percutaneous Coronary Sinus Catheterization With the ProPlege Catheter Under Transesophageal Echocardiography and Pressure Guidance.

Objectives: Percutaneous catheterization of the coronary sinus (CS) to enable the administration of retrograde cardioplegia may play an important role in minimally invasive cardiac surgery. A new specially designed device (ProPlege; Edwards Lifesciences, Irvine, CA) is described that can be placed under transesophageal echocardiography (TEE) and pressure guidance with a high rate of success and low rate of complications.

Design: Case series.
