Prosthesis-Patient Mismatch
I n this issue of iJACC, Dayan et al. (1) published a meta-analysis of prosthesis-patient mismatch (PPM) after aortic valve replacement from 58 studies involving 40,381 patients, mostly after surgical aortic valve replacement (SAVR). Their major findings were as follows: 1) moderate or greater (indexed effective orifice area [iEOA] <0.85 cm/m) PPM was associated with increased perioperative mor...
متن کاملProsthesis-patient size: measurement and clinical implications.
T his is the definition of prosthesis-patient mismatch framed by Rahimtoola1 when he coined the term in 1978. Rahimtoola suggested that the degree of prosthesis-patient mismatch could be quantified and that such quantification might aid in identifying patients at risk of clinical sequelae caused by this condition. DeCarlo and colleagues2 seek to undertake these tasks in their report on small-si...
متن کاملOperative Management – Patient-Prosthesis Mismatch
The main objective of aortic valve replacement (AVR) is to relieve left ventricular (LV) burden and normalized LV mass (LVM). During AVR, many surgeons make final decision to select the size of the prosthetic valve based on intraoperative measurement. It is ideal to place an aortic prosthesis that is appropriately sized to the patient. However, this is not always possible owing to insufficient ...
متن کاملPatient-prosthesis mismatch: the Japanese experience.
The concept of patient-prosthesis mismatch (PPM) was defined as existing "when the effective prosthetic valve area, after insertion into the patient, is less than that of a normal valve". However, based on the correlation between the mean transvalvular pressure gradient and the corrected effective orifice area (EOA), PPM is currently defined as an EOA corrected by a body surface area (BSA) of <...
متن کاملThe problem of valve prosthesis-patient mismatch.
Valve prostheses have played an important part in the past two decades in the management of patients with valvular heart disease. However, many of the devices used in valve replacement have introduced new clinical problems. This paper deals with some of the problems associated with valve replacement, including one not previously emphasized--valve prosthesis-patient mismatch, which may cause obs...
