Impact of Prosthesis‐Patient Mismatch on Left Ventricular Myocardial Mechanics After Transcatheter Aortic Valve Replacement
BACKGROUND The aim of this study was to compare left ventricular (LV) remodeling using myocardial strain between patients with severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR) with and without prosthesis-patient mismatch (PPM). METHODS AND RESULTS In a retrospective study, speckle-tracking echocardiography was used to measure global longitudinal strain (G...
متن کاملLeft Ventricular Outflow Tract Pseudoaneurysm after Aortic Valve Replacement.
Left ventricular outflow tract pseudoaneurysm is an uncommon complication following aortic valve replacement (AVR), occurring most frequently secondary to endocarditis. We present a case of a 47-year-old female with a history of intravenous drug abuse and a past surgical history of two AVRs (2001 and 2009 with aortic root replacement for endocarditis) who presented with symptoms of lower extrem...
متن کاملProsthesis-patient mismatch in the transcatheter aortic valve replacement era.
In an insightful report in 1978, Rahimtoola (1) pointed to the fact that “mismatch can be considered to be present when the effective prosthetic valve area, after insertion into the patient, is less than that of a normal human valve.” He recognized that most patients have some residual aortic stenosis after aortic valve replacement and suggested that moderate or severe residual aortic stenosis ...
متن کاملProsthesis-patient mismatch affects survival after aortic valve replacement.
BACKGROUND Surgeons traditionally avoid the use of "small" aortic prostheses because of the potential for residual left ventricular outflow tract obstruction and persistent transvalvular gradients. This study examines the ratio between prosthetic valve size and the body surface area (BSA) of patients undergoing aortic valve replacement (AVR). We sought to determine the effect of potential "pros...
متن کاملProsthesis-patient mismatch after "high-risk" aortic valve replacement.
S ince the initial description of prosthesispatient mismatch (PPM) more than 3 decades ago (1), the clinical import of PPM after surgical aortic valve replacement (SAVR) has been debated in the surgical published data. The phenotypic manifestation of PPM is an elevated aortic valve gradient after valve implantation. Although a number of indices have been used to characterize the frequency of PP...
