Figure 5 | TAVI with a self-expanding valve in a patient with severe left ventricular outflow tract (LVOT) calcification. a | Severe calcification of the noncoronary leaflet and the annulus at the aorto–mitral curtain is demonstrated on gated CT angiography. b | A pigtail catheter is positioned in the noncoronary cusp in a right anterior oblique projection and the 26 mm Evolut-R valve (Medtronic, USA) is positioned at the level of the aortic annulus. c | The valve is partially deployed then released, but the calcification continues to impair the lower portion of the valve scaffolding from fully expanding, d | leading to moderately severe paravalvular leak (PVL) by root aortography and by transthoracic echocardiography. e | Balloon postdilatation did not substantially reduce the PVL. f | Ultimately, a 12 mm Amplatzer Vascular Plug II (St. Jude Medical, USA), was placed across the area of the leak, g | reducing the severity of regurgitation to only trivial levels.
