Research and Scholarly Activity

Interventional Cardiology Fellowship at Newark Beth Israel Medical Center

• Described a different approach for brachiocephalic vessel cannulation during Carotid Stenting; now used commonly across the country
• First to demonstrate that the major aortic arch branches are crested along a line traversing the superior most and central most aspect of the aorta; a fact relevant to development of second-generation embolic prevention devices for TAVR
• First to describe the determinants of Aortic Arch Types in humans
• First to hypothesize and demonstrate in an animal model the pivotal role of the major aortic arch branches in subtending the mammalian heart in its normal anatomic position in the thorax
• First to describe age related downward deviation of the Inguinal Ligament
• First to challenge validity of time honored bony landmarks used for gaining Femoral access during cath lab procedures
• First to describe a new “Hybrid Closure for large bore Arteriotomy now in common use across the country
• First to report that hitherto unbeknownst the Axillary artery diameter approximates Common Femoral Artery diameter Paving the way for totally percutaneous Axillary Impella insertion and TAVR
• First on the Eastern Seaboard to perform a totally percutaneous Axillary Impella opening the door to a totally percutaneous TAVR
• First to describe the “Post Close” technique to salvage a failed large bore Arteriotomy during TAVR now a common practice across the country
• First to describe Bony Landmarks for safe Axillary artery access
• First to report safety and feasibility of Axillary approach for lower extremity peripheral interventions
• First to report that contrary to commonly held apriori belief crossing of the Aortic Valve in Aortic Stenosis is a diastolic phenomenon
• First to report the technique of using a covered stent to treat copious thrombus in a stent graft
• Based on some of the above work our graduate Dr Raj Tayal performed the first totally percutaneous Axillary TAVR in the United States at one of our sister hospitals
• First to demonsarate that CFA is alarmingly short in patients with high CFA bifurcation; a finding with obvious ramifications for LBA TAVR access
• First to demonstrate that presence of collaterals on Coronary angiography correlates with viability on Cardiac MR
• First to demonstrate RCA origin is in the plane of MAAB Takeoff plane
• First to demonstrate catheter course from L radial approach is totally different from a catheter course from CFA approach
• First to demonstrate catheter course from L radial approach is totally different from a catheter course from CFA approach
