BACKGROUND: It is believed that most of thrombi form in the left atrial appendage (LAA)before they emboli. Different surgical and percutaneouse approaches were suggested to manage the LAA. In this study we are evaluating the safety of clipping the LAA via minithoractotomy approach. METHOD: All consecutive patients who had minimally invasive mitral valve surgery with concomitant LAA clipping between December 2012 and February 2014 were included in the study. LAA exclusion was performed using AtriClip® LAA Exclusion System (Cincinnati, Ohio, AtriCure®)...

Takahiro Shiota
Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures...

Mitraclip(®) implantation is widely used as a valid alternative to conventional open-chest surgery in high-risk patients with severe mitral valve (MV) regurgitation. Although effective in reducing mitral regurgitation (MR) in the majority of cases, the clip implantation produces a double-orifice area that can result in altered MV biomechanics, particularly in term of hemodynamics and mechanical stress distribution on the leaflets. In this scenario, we combined the consistency of in vitro experimental platforms with the versatility of numerical simulations to investigate clip impact on MV functioning...

Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus...

Advancements in surgical technique and understanding of the pathophysiology of mitral valve (MV) dysfunction have led to improved outcomes. Seen as a development beyond measures of morbidity and mortality, health-related quality-of-life (HRQOL) outcome measures are becoming increasingly popular. These measures are important because complications following routine (i.e. low-risk) operations on the MV are uncommon and further markers of outcome are needed. Surgeons are increasingly operating earlier on asymptomatic patients and will need to prove that HRQOL is not impacted...

OBJECTIVE: Mitral valve regurgitation (MR) is the second most common heart valve disease in Europe. Without intervention, prognosis of severe symptomatic MR is poor. Percutaneous edge-to-edge mitral valve repair with MitraClip is a promising mitral regurgitation treatment technique in select, high-surgical-risk patients. The present objective was to describe the experience of a single center with MitraClip use in a high-risk series in Turkey. METHODS: Between May 2013 and September 2014, 28 high-surgical-risk patients with MR of at least grade 3+ and mean EuroSCORE of 26% underwent MitraClip implantation at our institution...

BACKGROUND: Mitral regurgitation (MR) is the second leading cause of valvular heart disease in the United States behind aortic stenosis. The percutaneous repair of the mitral valve (MitraClip, Abbott, Inc.) has been approved in the United States since 2013 as an alternative to traditional mitral valve surgery. However, many questions are left unanswered about when to perform this procedure and whom to perform it on. METHODS: We reviewed major published literature on the MitraClip from 2003-2016 to help guide clinical decision-making...

The MitraClip procedure has shown promising results in patients with high surgical risk. However, data concerning outcomes of open mitral valve surgery for failed MitraClip procedures are sparse. In a retrospective clinical investigation, baseline characteristics, intraoperative and histopathological findings, surgical indications and results of patients who required surgery after a failed MitraClip procedure were collected. Between March 2010 and May 2016, 25 patients presented at our department with severe mitral valve regurgitation following a failed MitraClip procedure...

BACKGROUND: Although associated with left heart pathologies, functional tricuspid regurgitation (FTR) is often left untreated during left heart surgery. Hence, owing to its degenerative character, reoperation is often needed, encompassing an impressive (25% to 35%) mortality rate. Thus transcatheter approaches to FTR are raising great interest. OBJECTIVES: The authors evaluated the post-treatment effectiveness of the edge-to-edge technique using the percutaneous mitral valve repair device in an ex vivo pulsatile model of FTR...

To date, S. alactolyticus endocarditis complicated by middle cerebral artery aneurysm has not been reported. We describe the case of a 65-year-old female with a history of hypertrophic cardiomyopathy with left ventricular outflow tract obstruction presenting with confusion and a apical holosystolic murmur. Angiography of the brain identified new bilobed left middle cerebral artery aneurysm. Serial blood cultures grew S. alactolyticus, and aortic and mitral valve vegetation were discovered on transesophageal echocardiography...

BACKGROUND: Percutaneous mitral valve repair using MitraClip® (MC) is a well-established method for a subset of patients with severe mitral regurgitation (MR) and high risk for surgical intervention. Amplatzer® Cardiac Plug (ACP) occludes left atrial appendage and allows the discontinuation of oral anticoagulation and prevention of thromboembolic stroke. Due to the need for femoral and transseptal access in both procedures, a single approach could lead to minor risk of further complications and shorter cumulative intervention time...

BACKGROUND: Few therapeutic options exist for patients with severe heart failure due to obstructive hypertrophic cardiomyopathy (HCM) who are at unacceptable surgical risk. We hypothesized that percutaneous plication of the mitral valve could reduce left ventricular outflow tract (LVOT) obstruction and associated mitral regurgitation, thereby leading to amelioration of heart failure symptoms. OBJECTIVES: This study sought to evaluate the potential effectiveness of percutaneous mitral valve plication as a therapy for patients with symptomatic, obstructive HCM...

AIMS: Transcatheter mitral valve implantation (TMVI) is a novel approach that may enable a less invasive effective reduction of mitral regurgitation (MR). A limitation of the MitraClip is that definitive implantation of a clip precludes future therapy with TMVI. The purpose of this paper is to describe contemporary treatment considerations in patients with mitral valve regurgitation. METHODS AND RESULTS: In this report we describe an attempted MitraClip implantation which resulted in no reduction of MR severity...
