Mid-term impact of patient-prosthesis mismatch on young and middle-aged patients undergoing surgery due to severe aortic stenosis

چکیده
Methods All patients younger than 70 years of age undergoing isolated aortic valve replacement from October 2005 to October 2011 were analyzed. Patient-prosthesis mismatch was defined as the indexed effective orifice area ≤ 0,85cm2/m2. We studied the impact of patient-prosthesis mismatch on mid-term overall mortality, cardiac events and New York Heart Association functional class using an analysis stratified for propensity score. Cardiac events were defined as cardiac death, sudden death, hospital readmission due to angina, syncope or heart failure or reoperation on aortic prosthesis.

Impact of patient-prosthesis mismatch on 30-day outcomes in young and middle-aged patients undergoing aortic valve replacement
BACKGROUND The impact of patient-prosthesis mismatch (PPM) on early outcomes in young and middle-aged patients undergoing conventional aortic valve replacement for severe aortic stenosis remains unknown. Our objective was to evaluate the incidence of some degree of PPM and its influence on early mortality and morbidity. METHODS We analyzed our single center experience in all patients <70 year...

متن کاملClinical predictors of prosthesis-patient mismatch after aortic valve replacement for aortic stenosis
OBJECTIVE We sought to ascertain predictors of Patient Prosthesis Mismatch, an independent predictor of mortality, in patients with aortic stenosis using bioprosthetic valves. METHOD We analyzed 2,107 sequential surgeries. Patient Prosthesis Mismatch was calculated using the effective orifice area of the prosthesis divided by the patient's body surface area. We defined nonsignificant, moderat...

BACKGROUND Patient-prosthesis mismatch (PPM) after aortic valve replacement (AVR) is the subject of continuing debate in the cardiac surgery field. OBJECTIVES The aim of this study was to evaluate the frequency and severity of patient-prosthesis mismatch (PPM) and the functional status of patients undergoing aortic valve replacement (AVR) using a CarboMedics prosthesis in the mid-term follow ...

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...
