Comparison of Left Ventricular Functional Recovery and Remodeling After Total Thoracoscopic Mitral Valve Repair and Replacement in Patients With Mitral Regurgitation and Mildly to Moderately Reduced Left Ventricular Ejection Fraction.

Total thoracoscopic mitral valve surgery (TT-MVS) is a minimally invasive technique for mitral regurgitation (MR), but its impact on left ventricular (LV) function and remodeling in patients with reduced LV ejection fraction (LVEF) is unclear. We retrospectively compared 94 patients who underwent total thoracoscopic mitral valve repair (TT-MVr) or total thoracoscopic mitral valve replacement (TT-MVR) for MR and reduced LVEF at our center from January 1, 2017, to December 31, 2022. We assessed LV functional recovery and remodeling by echocardiography at baseline, 1 week, 3 months, and 6 months after surgery.

Clinical Outcomes and Left Ventricular Functional Remodeling after Extracorporeal Membrane Oxygenation Assisted Percutaneous Coronary Intervention in Patients with Ischemic Cardiomyopathy: A Single-Center Retrospective Observational Study of 76 Cases.

Background: Ischemic cardiomyopathy (ICM) is a common condition that leads to left ventricular (LV) functional remodeling and poor prognosis. Extracorporeal membrane oxygenation (ECMO) can provide temporary circulatory support and facilitate percutaneous coronary intervention (PCI) in patients with ICM and hemodynamic instability. However, the impact of ECMO-assisted PCI on LV functional remodeling and clinical outcomes in ICM patients is unclear.

Two-incision totally thoracoscopic mitral valve repair combined with radiofrequency atrial fibrillation ablation in rheumatic mitral valve disease: Early results of a case series of 43 consecutive patients.

Background: Few studies have reported the outcomes of two-incision total thoracoscopic mitral valve repair (MVr) and concomitant radiofrequency atrial fibrillation ablation (RAFA) in patients with rheumatic mitral valve disease and atrial fibrillation (AF).

Methods: We retrospectively analyzed 43 consecutive patients who underwent MVr and RAFA through two-incision total thoracoscopic technique from October 2018 to June 2022. We collected data on baseline characteristics, perioperative outcomes, and early-term results.

Impact of frailty status on clinical and functional outcomes after concomitant valve replacement and bipolar radiofrequency ablation in patients aged 65 years and older.

Background: To evaluate the prognostic value of frailty in older recipients of concomitant valve replacement (VR) and bipolar radiofrequency ablation (BRFA), we examined whether clinical and functional outcomes differed between frail and non-frail groups of older patients referred for concomitant VR and BRFA.

Methods: In a single-center retrospective observational cohort study, we compared the clinical and functional outcomes in frail versus non-frail patients. Frailty was assessed using the 5-item Cardiovascular Health Study (CHS) frailty scale.

A combination of transcriptome and methylation analyses reveals the role of lncRNA in the proliferation and metastasis of breast cancer.

Background: DNA methylation status is strongly associated with the prognosis of breast invasive carcinoma (BRCA). Elucidating the mechanisms underlying DNA methylation coupled with determining its biological function is imperative to the effective development of treatment and prevention strategies for breast cancer.

Methods: We retrieved transcriptome and DNA methylation profiles of BRCA patients from The Cancer Genome Atlas (TCGA) database, then applied the "limma" package in R software to identify differentially expressed genes (DEGs) and aberrantly methylated genes.

Efficacy, safety, and long-term survival of concomitant valve replacement and bipolar radiofrequency ablation in patients aged 70 years and older: a comparative study with propensity score matching from a single-Centre.

Background: Concomitant bipolar radiofrequency ablation and valve replacement in the elderly remains controversial. In the current study, we aimed to compare the outcomes of concomitant valve replacement and bipolar radiofrequency ablation with valve replacement alone in elderly patients with atrial fibrillation (AF).

Methods: This was a retrospective study of patients aged ≥70 years who underwent valve replacement with or without bipolar radiofrequency ablation in a single-centre between January 2006 and March 2015.

Thoracoscope-Assisted Mitral Valve Replacement with a Small Incision in the Right Chest: A Chinese Single Cardiac Center Experience.

BACKGROUND The aim of this study was to investigate the safety, feasibility, and clinical effectiveness of thoracoscopy-assisted mitral valve replacement via thoracic right-anterior minimal incision. MATERIAL AND METHODS A retrospective analysis was conducted of 225 patients with mitral valve lesions who were treated in our hospital from August 2012 to August 2015. Group A included 105 patients undergoing thoracoscopy-assisted mitral valve replacement via a thoracic right-anterior minimal incision, and group B included 120 patients undergoing conventional mitral valve replacement.

Transthoracic Balloon Pulmonary Valvuloplasty for Treatment of Congenial Pulmonary Atresia Patients with Intact Ventricular Septum.

BACKGROUND To summarize our clinical experience in performing transthoracic balloon pulmonary valvuloplasty for the treatment of patients suffering from congenial pulmonary atresia with intact ventricular septum (PA/IVS). MATERIAL AND METHODS Between April 2009 and April 2016, 38 patients with PA/IVS underwent transthoracic balloon pulmonary valvuloplasty in our hospital. All of them were combined with patent ductus arteriosus, tricuspid insufficiency, and atrial septal defect or patent foramen ovale.
