Vivek Reddy, MD, of Mount Sinai Hospital implanted the United States' first miniature-sized, leadless cardiac pacemaker directly inside a patient's heart without surgery. The leads-free pacemaker is implanted by a cardiac electrophysiologist directly inside the heart during a catheter-guided procedure through the groin via the femoral artery. The device, resembling a small, metal silver tube, is only a few centimeters in length, making it less than ten percent the size of a traditional pacemaker. Commenting on forthcoming clinical trials, "This clinical research trial will be testing the latest innovative, non-surgical pacemaker option for patients experiencing a slowed heart beat," says Vivek Reddy, MD, the study's co-investigator who is Director of Electrophysiology Services at The Mount Sinai Hospital and Chairman of the Steering Committee of the study.
