BACKGROUND: The patho-etiology of mitral regurgitation (MR) has been suggested as a mediator of outcomes following mitral valve (MV) operations, particularly in ischemic functional mitral regurgitation (IMR). This study examined the independent association of MV etiology with mortality. METHODS: Using the Society of Thoracic Surgeons Database, all patients undergoing mitral valve replacement or repair from 2011-2014 were assessed. Patients who underwent concomitant surgical ablation, septal defect closure, tricuspid valve repair, or coronary artery bypass grafting were included...

Lithium metal anodes are considered to be the most promising anode material for next-generation advanced energy storage devices due to their high reversible capacity and extremely low anode potential. Nevertheless, the formation of dendritic Li, induced by the repeated breaking and repairing of solid electrolyte interphase layers, always causes poor cycling performance and low coulombic efficiency, as well as serious safety problems, which have hindered the practical application of Li anodes for a long time...

Adaptation and evolution of transcatheter aortic valve replacement (TAVR) technologies has led to approval of TAVR for consideration in patients at intermediate risk for surgical aortic valve intervention. As TAVR becomes more mainstream, attention is shifting toward percutaneous mitral valve (MV) repair and transcatheter MV replacement (TMVR) techniques. Transcatheter heart valves (both purpose-built and off-label-use TAVR valves) are being implanted during TMVR procedures to treat clinically significant MV disease (native disease, degenerated bioprosthetic valves, and dysfunctional surgical MV annuloplasty repairs) when the risk of open heart MV surgery is prohibitive...

Background: Mitral valve (MV) coaptation is very important in MV repair patients. But accurate quantitation of the degree of MV coaptation remains challenging. This study aimed to evaluate the utility of two-dimensional (2D) and three-dimensional (3D) transesophageal echocardiography (TEE) to assess MV coaptation before and after MV repair. Methods: Forty-eight patients [(age: 52.23±13.31 years; 26 men (54.17%)] undergoing MV repair for mitral regurgitation (MR) were studied...

Nephropathy is one of the most severe complications of diabetic patients. The therapeutic strategies for diabetic patients should not only focus on the control of blood glucose but also pay attention to the occurrence of diabetic nephropathy (DN). Coenzyme Q10 (CoQ10) has great therapeutic potential for DN. However, the clinical application of CoQ10 has been limited because of its low water-solubility and non-specific distribution. Liposomes were supposed to be an effective way for delivering CoQ10 to kidney...

OBJECTIVES: Mitral valve (MV) repair is the gold standard for treatment of degenerative mitral regurgitation. A variety of surgical techniques allow surgeons to achieve a high rate of MV repair even with MV diseases of other aetiologies. However, a certain number of repairs fail over time. The aim of this study was to review our single-centre experience of MV re-repair and analyse the mode of repair failure, re-repair safety and efficiency in relation to the initial aetiology. METHODS: Between 1997 and 2015, 91 patients underwent redo MV re-repair...

BACKGROUND: Ischemic mitral regurgitation (IMR) is a frequent complication of coronary artery heart disease and is associated with increased mortality. Controversies exists whether patients with moderate IMR may benefit from a combined procedure with coronary artery bypass grafting (CABG) and treatment of mitral regurgitation. METHODS: 451 patients with moderate IMR (grade 2) receiving either CABG alone (CABG only) or additional mitral valve repair or replacement (CABG+MV) were included in this observational single-centre study...

Background: Clinical decision-making in symptomatic patients after mitral valve (MV) repair remains challenging as echocardiographic reference values are lacking. In native MV disease intervention is recommended for mean transmitral pressure gradient (TPG) >15 mmHg or systolic pulmonary artery pressure (SPAP) >60 mmHg at peak exercise. Insight into standard stress echo parameters after MV repair may therefore aid to clinical decision-making during follow-up. Hypothesis: Stress echocardiography derived parameters in asymptomatic patients after successful MV repair differ from current guidelines for native valves...

PURPOSE: The aim of this study was to define a sutureless peripheral nerve repair technique with a vein graft and bone marrow-derived stem cells (BMSC) and compare it to epineural repair. MATERIALS AND METHODS: Thirty Wistar Albino rats were divided into five groups evenly. In the control group (C), epineural repair was performed. In the SV (suture + vein) and MSV (BMSC + suture + vein) groups, epineural repair was wrapped with a vein graft. In the V (vein) and MV (vein + BMSC) groups, sutureless repair using a vein graft was performed by taking sutures away from the regeneration site...

Successful mitral valve (MV) repair for degenerative mitral regurgitation (DMR) is mainly related to surgical expertise and MV anatomy. Although 2D echocardiography, specifically transoesophageal (TOE), provides precise information regarding MV anatomy, recent advancements in matrix technology meant a decisive step forward to the point where segmental MV analysis can be accurately performed from a noninvasive 3D transthoracic (TTE) approach. The aims of this study were: (a) to evaluate the feasibility and time required for real-time 3D TTE in a large consecutive cohort of patients with severe DMR in the assessment of MV anatomy; (b) to compare the accuracy of 3D TTE and 2D TOE versus surgical inspection in the recognition and localization of all components of the MV leaflets; (c) to establish the added diagnostic value of 3D colourDoppler examination to pure 3D morphologic evaluation...

Percutaneous intervention for mitral valve (MV) disease has been established as an alternative to open surgical MV repair in patients with prohibitive surgical risk. Multiple percutaneous approaches have been described and are in various stages of development. Edge-to-edge leaflet plication with the MitraClip (Abbott, Menlo Park, CA) is currently the only Food and Drug Administration-approved device specifically for primary or degenerative lesions. Use of the edge-to-edge clip for secondary mitral regurgitation is currently under investigation and may result in expanded indications...

BACKGROUND: Heart valve surgery guidelines suggest that tricuspid valve annuloplasty may be beneficial in patients with a tricuspid annulus (TA) ≥40 mm even in the absence of functional tricuspid regurgitation (TR) at the time of surgery for left-sided valve lesions (class 2a). Given the broad spectrum of degenerative diseases that affect the atrioventricular valves, we hypothesize that this measurement might not be predictive of TR after mitral valve (MV) repair. METHODS: The diameter of the TA was measured preoperatively in a cohort of 312 consecutive patients who had isolated MV repair for degenerative diseases...

Free flaps based on static slings principles cannot provide esthetic and functional outcomes at a desired level in total or close to total lip loss. Therefore, dynamic methods have become a current issue in recent years and especially the idea of functional gracilis free muscle flap has been suggested. In this study, we present a case of a successful total lower lip repair with this flap.In a 78-year-old female patient who was diagnosed with squamous cell carcinoma involving the entire lower lip, bilateral modified radical neck dissection and full-thickness total resection with 1 cm surgical margin so as to include both commissures of the tumor were performed and then a free gracilis muscle flap was transferred from the same side...
