The 3F Enable valve's retirement from the market leaves the Perceval and Intuity valves as the only two sutureless, rapid-deployment options for the global marketplace. Yet, a direct, comparative study of the functions of these two valves has proven challenging for researchers. This systematic review and meta-analysis compared the intraoperative performance and early clinical outcomes of the Perceval and Intuity valves, focusing on cases using sutureless and rapid-deployment methods for aortic valve replacement. Electronic databases, including PubMed/MEDLINE, OvidWeb, Web of Science, and the Cochrane Central Register of Controlled Trials, underwent a systematic search up to November 17, 2022, for publications (regardless of language) related to aortic valve replacement comparing the Perceval sutureless valve with the Intuity rapid-deployment valve. Our principal findings focused on early mortality and postoperative transvalvular pressure gradients. The following were deemed secondary outcomes for the study: aortic cross-clamp and cardiopulmonary bypass duration, paravalvular leak (any grade, encompassing moderate to severe), the need for pacemaker insertion, postoperative neurological complications (including stroke), and duration of the intensive care unit stay following aortic valve replacement. This meta-analysis involved ten non-randomized trials with 3526 patients (1772 in the sutureless group and 1754 in the rapid-deployment group) that were studied. Quality assessments, performed via the Newcastle-Ottawa Scale, averaged 690 (standard deviation = 0.99) out of 9 for the included studies. Following sutureless aortic valve replacement, mean and peak transvalvular pressure gradients were elevated compared to the outcomes seen after rapid-deployment aortic valve replacement. The necessity for aortic cross-clamping and cardiopulmonary bypass was, in contrast, lower in sutureless aortic valve replacement surgeries when contrasted with rapid-deployment aortic valve replacements. A lack of significant publication bias was evident from the funnel plot and Egger's test results. The postoperative hemodynamic profile for sutureless aortic valve replacement demonstrated elevated mean and peak transvalvular pressure gradients when measured against rapid-deployment aortic valve replacement. In contrast to conventional approaches, sutureless aortic valve replacement significantly minimized the time needed for the placement of the aortic cross-clamp and the cardiopulmonary bypass operation.

The objective of this study is to predict exercise tolerance in hypertrophic cardiomyopathy (HCM) patients by assessing left atrial strain (LAS) through treadmill exercise stress echocardiography using three-dimensional speckle tracking technology. In the period spanning January 2018 to January 2021, Sichuan Provincial People's Hospital prospectively enrolled 97 HCM patients who had undergone treadmill exercise stress echocardiography. This was complemented by 30 healthy control subjects. The HCM-1 group encompassed hypertrophic cardiomyopathy (HCM) patients whose metabolic equivalent task scores (METS) were 60 or lower, whereas the HCM-2 group was formed from those with METS scores greater than 60. An analysis of the LAS and exercise tolerance was performed. An analysis of ultrasound parameters was conducted to pinpoint those that might predict a worsening of exercise capacity, leading to the construction of a predictive model. Normal controls demonstrated significantly higher METS, Rest-LASr, Rest-LAScd, and Rest-LASct levels than HCM patients. The data revealed a considerable difference in parameters like age, target heart rate, LVMI, and LAVI. / '-Rest, / A s
