Immediate effect of Biosense guided percutaneous direct myocardial revascularization with holmium:yttrium aluminium garnet laser on myocardial contractility assessed by transesophageal echocardiography.

Abstract:

OBJECTIVE:To evaluate immediate changes in left ventricular wall motion in patients treated using Biosense direct myocardial revascularization laser system. METHODS:Regional wall motion in 10 patients undergoing catheter-based direct myocardial revascularization using a holmium:yttrium aluminium garnet laser was assessed by transesophageal echocardiography before and immediately after the procedure. RESULTS:Mild deterioration in wall-motion score occurred rarely for only three of 160 (1.9%) segments and did not induce clinical heart failure. CONCLUSION:With the current catheter-based laser myocardial revascularization strategy, mild deterioration in wall motion of treated segments was rarely observed and did not effect overall left ventricular function or induce clinical congestive heart failure.
