Anatomical and procedural features associated with aortic root rupture during balloon-expandable transcatheter aortic valve replacement.
BACKGROUND Aortic root rupture is a major concern with balloon-expandable transcatheter aortic valve replacement (TAVR). We sought to identify predictors of aortic root rupture during balloon-expandable TAVR by using multidetector computed tomography. METHODS AND RESULTS Thirty-one consecutive patients who experienced left ventricular outflow tract (LVOT)/annular/aortic contained/noncontained...
متن کاملComparison of balloon-expandable vs self-expandable valves in patients undergoing transcatheter aortic valve replacement: the CHOICE randomized clinical trial.
IMPORTANCE Transcatheter aortic valve replacement (TAVR) is an effective treatment option for high-risk patients with severe aortic stenosis. Different from surgery, transcatheter deployment of valves requires either a balloon-expandable or self-expandable system. A randomized comparison of these 2 systems has not been performed. OBJECTIVE To determine whether the balloon-expandable device is...
متن کاملOff-pump transapical balloon-expandable aortic valve endoprosthesis implantation.
OBJECTIVE The aortic valve replacement is a routine procedure, and involves replacement of the native valve/prosthesis. In most of the patients who undergo such procedure the risk is acceptable, but in some cases, such risk can justify contraindication. The minimally invasive transcatheter aortic valve implantation without cardiopulmonary bypass (CPB) has been shown to be viable, with lower mor...
متن کاملVery Late Migration of Balloon-Expandable Transcatheter Aortic Valve.
Color-flow Doppler transesophageal echocardiography during valve-in-valve TAVR illustrates the placement of a 23 mm Edwards Sapien 3 valve carefully positioned within a displaced 23 mm Edwards Sapien XT valve.
متن کاملAcquired Infrarenal Abdominal Aortic Coarctation: Treatment with Percutaneous Self Expandable Stent
Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...
