Totally thoracosopic mitral valve replacement (MVR) has been applied to mitral stenosis for many years. Three working ports are usually necessary, among which the longest port ranges from 6 to 8 cm. This study aimed to determine the safety and feasibility of the two-incision totally thoracoscopic approach for MVR, with the longest incision of 3 cm.From January 2014 to February 2016, 90 patients with mitral valve stenosis were retrospectively analyzed. Thirty-six (40%) patients were included in the two-incision group and 54 patients were operated on using the sternotomy approach...

BACKGROUND: Mitral valve replacement (MVR) in very young children is challenging. This study investigates the mechanisms for early bioprosthetic valve failure in very young patients through review of the macroscopic and microscopic findings in explanted bioprosthetic valves. METHODS: Patients who underwent MVR with a bioprosthetic valve at Boston Children's Hospital between January 2010 to April 2016 at <5 years of age were the subjects of this study. Valve failure was defined as prosthetic mitral valve explantation with mitral valve re-replacement...

BACKGROUND: Progression of tricuspid regurgitation (TR) may occur after mitral valve replacement (MVR). The study aim was to define the independent predictors for new severe TR after MVR to treat rheumatic heart disease. METHODS: A total of 413 patients (177 men, 236 women; mean age 40.9 ± 9.2 years) with rheumatic heart disease undergoing MVR without concomitant tricuspid valve repair at the authors' institute between 1995 and 2005, who did not have preoperative severe TR, were followed for at least one year postoperatively...

BACKGROUND: The native mitral lesion of active infective endocarditis implies a poor prognosis and is associated with adverse short- or long-term results without surgical treatment. Both mitral valvuloplasty (MVP) and mitral valve replacement (MVR) have been performed in the treatment of active native mitral infective endocarditis (ANMIE). However, the outcomes of the two approaches remain unclear. The aim of this study was to systematically review the two procedures with mortality and survival as the primary endpoints...

OBJECTIVES: This study aimed to assess mitral valve function after repair of ventricular septal defect (VSD) combined with mitral regurgitation (MR) in the mid-term follow-up period, to evaluate the clinical utility of simultaneous mitral valve repair (MVR). METHODS: From June 2005 to March 2014, 60 patients with VSD and MR underwent surgical treatment. After performing propensity score analysis (1:1) for the entire sample, 46 patients were selected and divided into 2 groups: those with VSD closure and MVR (VSD + MVR, 23 patients) and those with VSD closure without mitral valve intervention (VSD only, 23 patients)...

Urethane products that contain isocyanates are extensively used in the motor vehicle repair (MVR) industry and other industries such as furniture and cabinet-making as two-pack spray paints, clears, and adhesives. Attention has recently been refocussed on isocyanate-containing chemicals, particularly in paints. The spray painters in the MVR industry had a propensity to develop industrial asthma at a rate 80 times higher than the general public, which was previously reported in the UK. To track workers exposure to isocyanates, urine samples were collected from 196 spray painters who worked mainly in 78 MVR shops across 54 New South Wales (NSW) towns and suburbs...

BACKGROUND: Multivisceral resections combined with pancreatectomy have been proposed in selected patients with tumor invasion into adjacent organs, in order to allow complete tumor resection. Some authors have also reported multivisceral resection combined with metastasectomy in very selected cases. The utility of this practice is debated. The aim of the review is to compare the postoperative results and survival of pancreatectomies combined with multivisceral resections with those of standard pancreatectomies...

BACKGROUND: The prognosis and survival of patients with advanced gastric cancer is poor. Although completeness of resection (R0) is one of the most important factors affecting survival, multivisceral resection (MVR) for locally advanced (clinical T4b, cT4b) gastric cancer remains controversial. The aim of this study was to evaluate the factors affecting prognosis and survival after MVR in patients with cT4b gastric cancer. METHODS: Between 2005 and 2015, we retrospectively reviewed the medical records of 103 patients who underwent MVR for cT4b gastric cancer with suspected direct invasion to adjacent organs...

Prosthetic valve paravalvular leak (PVL) is a known and relatively common complication of surgical valve replacement, which may lead to significant morbidity. Patients with significant mitral valve replacement (MVR) PVL typically present with symptoms of heart failure and elevated filling pressures or with hemolytic anemia. Percutaneous closure of these leaks has become the preferred therapy. Percutaneous closure of MVR PVL can be technically challenging, given the anatomy of the approach (trans-septal, trans-apical), the level of associated comorbidities and the geographic location of the paravalvular defect...

Severe aortic valve stenosis (AVS) and mitral valve regurgitation (MVR) often coexist. Although a fully percutaneous treatment for the two conditions, by means of transcatheter aortic valve implantation (TAVI) followed by MitraClip, can be appealing in selected high-risk candidates, critical and strategical reasoning should be applied. In a 3-year period we have developed a single-centre experience of 14 patients who were managed with a staged percutaneous approach to treat severe AVS and MVR. The average interval from TAVI to MitraClip repair was 101 ± 12 days...

Several reports have described that the prognosis of patients with mitral valve regurgitation due to active infective endocarditis (IE) is better after mitral valve plasty (MVP) than replacement (MVR). However, extensive destruction of valve tissue might cause difficulties with MVP. We repaired a widely-affected anterior mitral leaflet (AML) using an autologous pericardial patch. A 44-year-old woman with mitral regurgitation presented with prolonged fever and backache. We made a diagnosis of active IE accompanied by mitral valve regurgitation...

BACKGROUND: Induction of insulin resistance is a key pathway through which obesity increases risk of type 2 diabetes, hypertension, dyslipidemia, and cardiovascular events. Although the detrimental effects of obesity on insulin sensitivity are incompletely understood, accumulation of visceral, subcutaneous, and liver fat and impairment of insulin-induced muscle microvascular recruitment (MVR) may be involved. As these phenotypic changes often coincide in obesity, we aimed to unravel whether they independently contribute to insulin resistance and thus constitute separate targets for intervention...
