Currently, the most common technique to restore valve com...

The absence of clinical response in 30% to 40% of patients receiving cardiac resynchronization therapy (CRT) poses a great challenge to heart failure clinicians and device implanters. It is well documented that positioning of the left ventricular (LV) lead in areas of myocardial scar in patients with ischemic cardiomyopathy is associated with a diminished response to CRT. Regions of slow conduc...
