The high recurrence rate of mitral regurgitation (MR) in patients with atrial functional mitral regurgitation (AFMR) who underwent mitral annuloplasty (MAP) is reported.

The use of thyroid hormone supplementation (THS) for donor optimization has not been standardized and remains an area of academic investigation and clinical interest. The purpose of this study is to investigate the impact of THS supplementation on heart transplant recipient outcomes. <i>Methods</i>. Adult heart transplant recipients in the UNOS database recorded from January 1, 2000 to June 30, 2022 formed the study cohort. Simple comparisons were made with <i>t</i>-tests or chi-squared tests.

The cohort consisted of 46,542 heart transplants, of which 28,911 (62%) received THS prior to organ procurement.

The 2018 Organ Procurement and Transplantation Network (OPTN) heart allocation policy change prioritizes patients bridged to transplant with mechanical circulatory support (MCS) devices, including extracorporeal membrane oxygenation (ECMO).

We reviewed the OPTN database for adult patients undergoing heart transplant after bridge with ECMO between January 1^st 2000 and October 18^th 2018.

Multivessel coronary artery disease (CAD) and left ventricular dysfunction (LVD) present challenges in CABG. We aimed to compare early outcomes of total arterial revascularization (TAR) versus conventional CABG in this high-risk population. <i>Methods</i>. This was a retrospective cohort study based on a single-center registry of patients who underwent isolated CABG for multivessel CAD and LVD between January 2014 and December 2022. Primary outcome was in-hospital mortality. Secondary outcomes were early complications, graft patency rate at 3 months, readmission rate within 6 months, and freedom from angina rate within 6 months. <i>Results</i>. A total of 112 cases were included in this study; 52 patients for TAR and 60 patients for conventional CABG. Both groups had comparable baselines and operative profiles. In-hospital mortality was similar between TAR and conventional CABG (2 deaths, 3.85% vs 4 deaths, 6.67%, <i>p</i> = 0.810).

This study aimed to compare the characteristics and outcomes of SLE patients compared to non-SLE patients undergoing CABG. <i>Methods</i>. We utilized the Nationwide Inpatient Sample (NIS) data from 2008–2018 for CABG patients ≥18 years old. Patients were divided into two groups based on SLE status (confirmed SLE diagnosis or no SLE present). Primary outcomes were in-hospital mortality, favorable discharge, and length of stay (LOS).

Minimally invasive mitral valve repair (MIMVR) has been demonstrated to be safe and effective, but technical difficulty, outcome variation, and lack of standardized protocols undermine the utility of artificial chordae. This study aims to analyze the midterm outcomes of repair using artificial chordae through right minithoracotomy. <i>Methods</i>. A retrospective cohort study was conducted on consecutive patients who underwent MIMVR using artificial chordae at a single center in Vietnam between April 2016 and April 2022. Valve repairs were separated into two groups based on a previously validated complexity score: simple repair (Group 1) and intermediate-to-complex repair (Group 2). Demographic variables, comorbidities, operative characteristics, surgical outcomes, and follow-up data on survival and mitral regurgitation (MR) grade were analyzed. The learning curve was assessed by comparing the number of procedures with operation time and aorta cross-clamp time. Primary endpoints included survival and freedom from recurrent MR at four years. <i>Results</i>. Ninety patients were identified, including 41 simple and 49 intermediate-to-complex repairs. The mean age was 50.5 ± 12.9 years. Both groups had similar preoperative characteristics. The perioperative and postoperative outcomes were favorable, with no cases requiring mitral valve replacement. The median follow-up time was 30.3 months (18.2–40.4), and there were two (2.2%) cardiac deaths, with one in each group. The Kaplan–Meier survival estimates for Groups 1 and 2 at 12 and 24 months were 97% vs. 100% and 97% vs. 96%, respectively (95% CI = 0.05–12.2, <i>P</i> = 0.850), and estimates for freedom from recurrent MR were 97% vs. 92% and 97% vs. 88%, respectively (95% CI = 0.49–12.0, <i>P</i> = 0.260). There was a negative association between the volume of operations and the duration of operation and aortic cross-clamp time, leading to shorter durations. <i>Conclusion.</i> Based on our single-center experience, MIMVR using artificial chordae via right mini-thoracotomy can be safely and effectively performed in resource-limited countries for patients with MR. This approach has been shown to be applicable for a range of MR complexities, from simple to intermediate-to-complex MV repairs, and has demonstrated promising results in terms of midterm freedom from MR recurrence.</p>\u0000 </div>","PeriodicalId":15367,"journal":{"name":"Journal of Cardiac Surgery","volume":"2023 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2023/5510950","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138595115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
