Prosthesis-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 کاملTranscatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کاملPatient-prosthesis mismatch in patients with aortic valve replacement
OBJECTIVE Patient-prosthesis mismatch (PPM) may affect clinical outcomes in patients with aortic valve replacement (AVR). We retrospectively examined the PPM in patients with isolated AVR in the Japan Adult Cardiovascular Surgery Database (JACVSD). METHODS We examined all patients with isolated AVR between January 1, 2008 and December 31, 2009. The JACVSD data collection form has a total of 2...
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...
