European Journal of Cardio-Thoracic Surgery, 2020
OBJECTIVES There is no consensus regarding the use of biological or mechanical prostheses in patients 50–69 years of age. Previous studies have reported a survival advantage with mechanical valves. Our goal was to compare the long-term survival of patients in the intermediate age groups of 50–59 and 60–69 years receiving mechanical or biological aortic valve prostheses. METHODS We conducted a retrospective analysis of patients in the age groups 50–59 years (n = 329) and 60–69 years (n = 648) who had a first-time isolated aortic valve replacement between 2000 and 2019. Kaplan–Meier and competing risk analyses were performed to compare survival, incidence of aortic valve reoperation, haemorrhagic complications and thromboembolic events for mechanical versus biological prostheses. RESULTS Patients aged 50–59 years with a biological prosthesis had a higher probability of aortic valve reintervention (26.3%, biological vs 2.6% mechanical; P < 0.001 at 15 years). The incidence of haem...
Cardiac valve replacement with mechanical prostheses in patients aged 65 years and over
The Journal of heart valve disease, 2004
Recent data regarding the performance of mechanical prostheses in patients aged > or =65 years are scant. Hence, the outcome of mechanical prosthesis implantation in this age group has been retrospectively evaluated. Between January 1990 and October 2002, 253 patients (163 males, 90 females) aged > or =65 years (mean age 68.2 years) underwent aortic valve replacement (AVR) and/or mitral valve replacement (MVR) at the authors' institution. Among the patients, 94 (37.2%) had MVR, 137 (54.1%) had AVR, and 22 (8.7%) had MVR+AVR. In total, 99 patients (39.1%) had concomitant coronary artery bypass grafting (CABG). The early mortality rate was 11.1%; that for patients aged > or =70 years was greater than that for patients aged 65-69 years (14.5% versus 9.6%, p <0.001). The overall actuarial survival was 91.3 +/- 2.4% at 5 years, 81.1 +/- 4.1% at 8 years, and 73.8 +/- 6.3% at 10 years. Actuarial survival for patients with isolated AVR and MVR at 10 years was 84.7 +/- 6.0% a...

The aim of the present study is to report the early and mid-term clinical and haemodynamic results of the St Jude Medical Regent 19-mm aortic mechanical prothesis (SJMR-19). Between January 2002 and January 2012, 265 patients with aortic valve disease underwent AVR (Aortic Valve Replacement) with a SJMR-19 (St Jude Medical Regent Nr.19). There were 51 males. Mean age was 67.5±12.72years and mean body surface area (BSA) was 1.67±0.14m2. Thirty-six patients required annulus enlargement. The mean follow-up was 34.5±18.8months (range 6-60 months). All patients underwent echocardiographic examination at discharge and within one year after surgery. There were 14 (5.3%) hospital deaths. Six of the hospital deaths were identified in patients undergoing reoperation, significantly higher than patients undergoing first time operation (p=0.0001). Also the postoperative mortality was significantly higher in patients undergoing annulus enlargement versus patients not requiring annulus enlargement...

Methods. From January 1984 through July 1997, combined AVR ؉ CABG was performed in 750 consecutive patients; 469 received BAVR and 281 received MAVR. BAVR recipients were significantly older (mean age, 75 vs 65 years), and had more nonelective operations, congestive heart failure, peripheral vascular disease, preoperative intraaortic balloons, lower cardiac indices, more severe aortic stenosis, less aortic regurgitation, and more extensive coronary artery disease.
Surgical Aortic Valve Replacement—Age-Dependent Choice of Prosthesis Type
Journal of Clinical Medicine
Background: Recently, the use of surgically implanted aortic bioprostheses has been favoured in younger patients. We aimed to analyse the long-term survival and postoperative MACCE (Major Adverse Cardiovascular and Cerebral Event) rates in patients after isolated aortic valve replacement. Methods: We conducted a single-centre observational retrospective study, including all consecutive patients with isolated aortic valve replacement. 1:1 propensity score matching of the preoperative baseline characteristics was performed. Results: A total of 2172 patients were enrolled in the study. After propensity score matching the study included 428 patients: 214 biological vs. 214 mechanical prostheses, divided into two subgroups: group A < 60 years and group B > 60 years. The mean follow-up time was 7.6 ± 3.9 years. Estimated survival was 97 ± 1.9% and 89 ± 3.4% at 10 years for biological and mechanical prosthesis, respectively in group A (p = 0.06). In group B the survival at 10 years w...

Objective: Aortic valve replacement using a tissue valve is controversial for patients younger than 60 years old. The long-term survival in this age group, the expected event rates during long-term follow-up, and valve-related complications are not clearly determined. , overall survival, valve-related events, and echocardiographic outcomes were analyzed in all patients younger than 60 years of age, who underwent biologic aortic valve replacement. Patients who received a Perimount Carpentier-Edwards pericardial tissue valve (n ¼ 103) were selected and compared with a propensity matched group of 103 patients who received aortic valve replacement using a mechanical bileaflet valve. The mean follow-up was 33 AE 24 months (range, 2-120), and the mean age at implantation was 50.6 AE 8.8 years (bioprosthesis, 55 AE 8.9 years; mechanical valve, 50 AE 8.6 years; P ¼ .03).
