WebbPatient-prosthesis mismatch (PPM) remains one out of many factors to be considered during decision-making for the treatment of aortic valve pathologies. The idea of adequate sizing of a prosthetic heart valve was established by Rahimtoola already in 1978. Webb5 mars 2007 · Background— We recently reported that valve prosthesis-patient mismatch (PPM) is associated with persisting pulmonary hypertension after mitral valve replacement. Thus, the objective of this study was to evaluate the impact of PPM on mortality in patients undergoing mitral valve replacement.

WebbPatient-prosthesis mismatch (PPM) is a controversial issue in current clinical practice. PPM has been reported to have a negative impact on patients' prognosis after aortic valve replacement in several studies, showing increased all-cause and. Webb1 apr. 2024 · CONCLUSIONS: In bileaflet mechanical valve prostheses, there is no clinically relevant increase in EOA during dynamic exercise. Transprosthetic gradients during exercise closely adhere to the fundamental pressure-flow relationship. Indexed EOA at rest is a strong predictor of exercise capacity in MVR patients. Webb23 sep. 2024 · Results: Severe and moderate PPM were present following TAVR in 12% and 25% of patients, respectively. Predictors of severe PPM included small (≤23 mm diameter) valve prosthesis, valve-in-valve procedure, larger body surface area, female sex, younger age, non-White/Hispanic race, lower ejection fraction, atrial fibrillation, and severe mitral ... flight tickets to venice
