A Step-Wise Approach to Preventing LVOT Obstruction in Patients Undergoing TMVR With High Risk Anatomy and Addressing Valve Popout in TAVR
Benjamin Galper, MD, MPH, FACC, Director of Structural Heart Disease Program Mid-Atlantic Permanente Medical Group (MAPMG), Assistant Chief of Cardiology at MAPMG Northern Virginia service area, Medical Director of Structural Heart Disease Program at Virginia Hospital Center, shares two cases detailing the intraprocedural steps of a LAMPOON procedure for a transcatheter mitral valve replacement (TMVR) procedure at a high risk of left ventricular outflow tract (LVOT) obstruction and a rescue procedure of a pop out transcatheter aortic valve replacement (TAVR) valve.
