Mitral regurgitation due to bileaflet prolapse and ischemic causes can be difficult to repair. Midterm experience of the Alfieri edge-to-edge repair as an alternative to valve replacement is reported. Twenty-six patients with severe mitral regurgitation underwent the Alfieri repair between January 1998 and December 2000 (group 1); 15 cases were due to bileaflet prolapse and 7 were of ischemic origin. During the same period, valve replacement was performed in 36 patients (group 2), 20 of whom had similar indications. Follow-up was complete to a mean of 15 months (range, 1-28 months). There was no early death in either group. During follow-up, there was no reoperation in group 1, while 2 patients in group 2 required reoperations due to prosthetic valve endocarditis. There were 4 major thromboembolic or bleeding events in group 2, and none in group 1. All patients in group 1 had trivial to mild mitral regurgitation on follow-up echocardiography. The mean mitral valve gradient was significantly higher in group 2 compared to group 1 (7.2 versus 3.2 mm Hg, p = 0.001). The edge-to-edge repair is associated with good early and midterm results. Long-term follow-up is required to evaluate the durability of this technique.

Department of Cardiology, Xuzhou Central Hospital, No.199 Jiefang South Road, Quanshan District, Xuzhou, 221009, People's Republic of China.
Background: The aim of this study is to identify factors associated with the development of long-term severe tricuspid regurgitation (TR) following mitral valve replacement (MVR).
Methods: A retrospective analysis was conducted involving 308 patients who underwent single-valve MVR at Xuzhou Central Hospital between April 2017 and December 2022. Preoperative color Doppler ultrasound indicated that all patients had either no or mild to moderate tricuspid regurgitation.

Department of Anaesthesiology, West China Hospital, Sichuan University & The Research Units of West China (2018RU012), Chinese Academy of Medical Sciences, Chengdu, 610041, China.
Background: Given the prevalence of cardiovascular disease, encountering difficult airways in this patient population is quite common. The challenge for anesthesiologists lies not only in establishing the airway but also in managing the hemodynamic instability caused by sympathetic activation during intubation. The purpose of this report is to describe the anesthetic experience of this patient with severe mitral and tricuspid regurgitation, atrial fibrillation with rapid ventricular response, and moderate pulmonary hypertension with an anticipated difficult airway.

Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia, with ventricular rate control being a critical therapeutic target. However, the optimal range for ventricular rate control remains unclear. Additionally, the relationship between different levels of ventricular rate control and cardiac remodeling in patients with atrial fibrillation remains unclear.

Unlabelled: The Bland-White-Garland syndrome, or Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA) syndrome, is a rare congenital cardiac anomaly often associated with high mortality, if left untreated. We present a case of a 43-year-old female with undiagnosed ALCAPA who initially underwent mitral valve surgery for severe mitral regurgitation, only to require reoperation due to adult-type ALCAPA. Intraoperatively, the discovery of dilated right coronary artery and its branches and absence of the left coronary ostium prompted further investigation, leading to the diagnosis of adult-type ALCAPA.

Minimally invasive mitral valve surgery (MIMVS) is revolutionizing the field of cardiothoracic surgery by offering patients less invasive alternatives to conventional sternotomy. This article reviews recent research and studies on the outcomes, challenges, and considerations surrounding MIMVS. Comparative studies reveal that while MIMVS offers advantages such as shorter hospital stays and reduced recovery times, it shows no significant differences in mortality or long-term quality-of-life outcomes compared to traditional methods.
