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...

OBJECTIVES: We sought to determine the effects of experience on the Mitraclip(®) procedure steps as well as procedure safety and functional results. BACKGROUND: MR has proven deleterious in heart failure. Mitraclip(®) therapy evolved an important option in patients with severely reduced left ventricular function (LVEF). METHODS: Between 2011 and 2016, 126 consecutive patients were grouped in three groups and investigated in a prospective observational study...

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...

HISTORY AND ADMISSION FINDINGS: We report on a 48-year-old man presenting with progressive hepatopathy and encephalopathy for two weeks based on a chronic hepatitis C. He takes ledipasvir and sofosbuvir (Harvoni) and ribavirin for almost 24 weeks. After admission to hospital his state deteriorated rapidly. He is directly transferred to the medical intensive care unit, where he died on day 3. INVESTIGATIONS: During the physical examination, a pronounced jaundice and significant peripheral edema were found...

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: Mitral regurgitation represents a volume load on the left ventricle leading to congestion and symptoms of heart failure. The aim of this study was to characterize early hemodynamic adaptions after percutaneous mitral valve (MV) repair. METHODS: Forty-six consecutive patients with symptomatic high-grade MV insufficiency (mean age, 72 years; 54% men) were prospectively included in the study and examined before and after successful catheter-based clip implantation...

BACKGROUND: The goal of this study was to determine changes in left atrial (LA) function with two-dimensional speckle tracking echocardiography (2DSTE) and real-time full-volume three-dimensional echocardiography (RT3DE) after percutaneous mitral valve repair with the MitraClip system. Furthermore, we investigated whether baseline and/or changes in LA function after MitraClip repair had any impact on prognosis. METHODS: A total of 25 consecutive patients (age: 57±12 years, 76% male) with moderate-to-severe or severe mitral regurgitation (MR) were included...

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: Gender has been an important factor in outcomes after mitral valve surgery; however, its effect on percutaneous mitral valve repair is not well known. We aimed to report the effect of gender on outcomes in a large European prospective, multicentre, non-randomised post-approval study of percutaneous mitral valve repair. METHODS AND RESULTS: Two hundred and five female and 362 male patients with significant mitral regurgitation underwent percutaneous repair at 14 European sites from October 2008 to April 2011...

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...

MitraClip (Abbott Vascular) therapy has been reported to be an effective procedure for mitral regurgitation, especially in high-risk patients. Recently, the novel pushing maneuver technique has been described for approaching restricted and short posterior leaflets with a pigtail catheter in order to facilitate grasping of the clip. However, complications or unexpected situations may occur. We report the case of an 84-year-old patient who underwent MitraClip implantation wherein the pushing maneuver was complicated by the clip accidentally gripping the pigtail catheter along with the two leaflets...

Based on the principle of surgical edge-to-edge mitral valve repair (MVR), the MitraClip percutaneous MVR technique has emerged as a minimally invasive option for MVR. This catheter-based system has been widely demonstrated to be safe, although inferior to surgical MVR. Studies examining patients with ≥3+ mitral regurgitation (MR) show that, for all patients treated, freedom from death, surgery, or MR ≥3+ is in the 75%-80% range 1 year following MitraClip implantation. Despite its inferiority to surgical therapy, in high-risk surgical patients, data suggest that the MitraClip system can be employed safely and that it can result in symptomatic improvement in the majority of patients, while not precluding future surgical options...

AIMS: While severe tricuspid regurgitation contributes significantly to morbidity and a poor prognosis in heart failure patients, isolated surgical repair of the tricuspid valve is associated with a high mortality, especially in patients with prior surgery. Percutaneous tricuspid valve repair could contribute to the solution of this dilemma. A recently published report demonstrated the feasibility of tricuspid edge-to-edge repair with the MitraClip® system (Abbott Vascular, Santa Clara, CA, USA) using a transjugular route...

AIMS: The aim of this study was to investigate the feasibility, safety, and efficacy of Mitraclip therapy in patients with functional mitral regurgitation (MR) and missing leaflet coaptation (MLC). METHODS AND RESULTS: Out of 62 consecutive patients with functional MR undergoing Mitraclip implantation, 22 had MLC defined as the presence of a 'gap' between two mitral leaflets or insufficient coaptation length (<2 mm), according to the EVEREST II criterion. Compared with the control group, the MLC population had a significantly higher effective regurgitant orifice area (0...

BACKGROUND: Analyses emphasizing gender-related differences in acute and long-term outcomes following MitraClip therapy for significant mitral regurgitation (MR) are rare. METHODS: 592 consecutive patients (75 ± 8.7 years, 362 men, 230 women) underwent clinical and echocardiographic follow-up for a median of 2.13 (0.99-4.02) years. RESULTS: Significantly higher prevalence of cardiovascular comorbidities, renal failure, and adverse echocardiographic parameters in men resulted in longer device time (p = 0...
