Abstract Background: The prosthesis selection in patients with small aortic annulus undergoing aortic valve replacement (AVR) has always been a challenge, especially in dual valve replacement (DVR, combined aortic and mitral valve replacement). The present study aimed to analyze early-term hemodynamic parameters of 19-mm St. Jude Medical Regent ( SJMR19 ) valve in patients with small aortic annulus undergoing DVR. Methods: Between January 2015 to December 2020, 54 patients with small aortic annulus who underwent DVR were divided into two groups: SJMR19 valve group (n=30) and 21-mm mechanical (M21) valve group (n=24). The perioperative and early-term hemodynamic data were collected and analyzed. Results: A significant difference in terms of maximum transaortic flow velocity (Vav max), maximum transaortic pressure gradient (PGav max), left ventricular mass index (LVMi) and left ventricular mass (LVM) was observed postoperatively in both groups. The postoperative left ventricular ejection fraction (LVEF) was significantly higher while the LVM and LVMi was evidently decreased in the SJMR19 group, compared with the M21 group. In order to confirm the influencing factors on postoperative LVEF, a multiple linear regression analysis model was established by including all candidate variables and the implanted valve type was identified in the multivariate analysis as an independent predictor for postoperative LVEF. Conclusions: The postoperative cardiac function and hemodynamic parameters was improved both in the SJMR19 and M21 groups. The postoperative LVEF, LVM and LVMi were better in the SJMR19 group compared with those of the M21 group. And the implanted valve type might possess the predictive value of postoperative LVEF in patients with small aortic annulus undergoing DVR.

Left ventricular hypertrophy in aortic stenosis is considered a compensatory response for the maintenance of systolic function but a risk factor for cardiac morbidity and death. We investigated the degree of left ventricular mass regression after implantation of the sutureless Medtronic 3f Enable® Aortic Bioprosthesis. We studied 19 patients who, from May 2010 through July 2011, underwent isolated aortic valve replacement with the 3f Enable bioprosthetic valve, with clinical and echocardiographic follow-up at 6 months. The mean age was 77.1 ± 5.1 years (range, 68–86 yr); 14 patients were women (73.7%); and the mean logistic EuroSCORE was 15.4% ± 11.8%. Echocardiography was performed preoperatively, at discharge, and at 6 months' follow-up. The left ventricular mass was calculated by means of the Devereux formula and indexed to body surface area. The left ventricular mass index decreased from 146.1 ± 47.6 g/m2 at baseline to 118.1 ± 39.8 g/m2 at follow-up (P=0.003). The left ventricular ejection fraction did not change significantly. The mean transaortic gradient decreased from 57.3 ± 14.2 mmHg at baseline to 12.3 ± 4.6 mmHg at discharge and 12.2 ± 5.3 mmHg at follow-up (P <0.001), and these decreases were accompanied by substantial clinical improvement. No moderate or severe paravalvular leakage was present at discharge or at follow-up. In isolated aortic stenosis, aortic valve replacement with the 3f Enable bioprosthesis results in significant regression of left ventricular mass at 6 months' follow-up. However, this regression needs to be verified by long-term echocardiographic follow-up.

Background: Alcohol drinking is cardio-protective; however its beneficial and harmful effects depend on the amount consumed. This work is designed to assess the impact of prolonged non-moderate drinking in left ventricular mass index and left ventricular ejection fraction and the correlation of their severity with total lifetime intake amount. Materials and methods: Fifty non-moderate drinkers (>25 g/day) for last 10 years and 50 non-drinker-volunteers were selected. Detail echocardiographic assessment was done and findings were compared and severity was correlated with lifetime amount. Results: Mean daily intake, duration and lifetime intake amount of alcohol were 64.1 g, 21.9 years and 501.9 Kg respectively. The mean ejection fraction and left ventricular mass index were 47.2% and 105.3 g/m2. There was significant difference when compared with controls. Eighty-two percent drinking subjects had abnormal echo, most common were regurgitations (52%), diastolic dysfunction (46%), raised ventricular mass (44%), systolic dysfunction (40%), and dilated left atrium and ventricle (38%). Thirty-four percent of subjects had echo features consistent with dilated cardiomyopathy. Palpitation and dyspnea in combination were the only symptoms associated with severity of echo changes. There was strong negative correlation of lifetime intake amount with ejection fraction (r = -0.91, p<0.001); however its relationship with ventricular mass index was not statistically significant (r = 0.23, p>0.05). Conclusions: Prolonged non-moderate drinking causes significant echocardiographic abnormalities mainly systolic dysfunction and increased left ventricular mass index. The total lifetime and daily amount of alcohol are well correlated with systolic dysfunction; however their relationships with the left ventricular mass index were non-conclusive.
