Transcatheter mitral valve implantation (TMVI) has been performed in high-risk and inoperable patients for degenerated mitral bioprostheses (TMVIinV) and failed annuloplasty rings (TMVIinR). TMVIinR is more challenging compared to TMVIinV because of the differences in dimensions, shapes, and contours between rings and valves. In this report, we present two clinical cases of TMVIinR that were treated by trans-septal implantation of a balloon-expandable prosthesis. In TMVI cases with an incomplete ring, the ring will be stretched out toward its anterior and commissural side, and the open side of the ring will increase in width...

The natural history of mitral regurgitation (MR) results in significant morbidity and mortality. Innovations in non-invasive imaging have provided new insights into the pathophysiology and quantification of MR, in addition to early detection of left ventricular (LV) dysfunction and prognostic assessment in asymptomatic patients. Transthoracic (TTE) and transesophageal (TOE) echocardiography are the mainstay for diagnosis, assessment and serial surveillance. However, the advance from 2D to 3D imaging leads to improved assessment and characterization of mitral valve (MV) disease...

PURPOSE OF REVIEW: Analyze the current state of the art and the future perspectives of mitral interventions in clinical setting. RECENT FINDINGS: A systematic and critical review of the new mitral percutaneous therapies and imaging technologies is the basis to adopt the right treatment for each patient according to specific valve dysfunction and clinical presentation, waiting for definitive guidelines. While surgical mitral repair will remain the gold standard for low-risk healthy patients with degenerative mitral regurgitation (DMR), transcatheter mitral valve repair is becoming first line therapy in high risk patients with functional mitral regurgitation (FMR)...

Functional ischemic mitral regurgitation is strongly associated with poor outcomes in patient with coronary artery disease. The best management for mitral regurgitation at the time of coronary revascularization remains controversial. We report, a case of 58 years-old men admitted to GKNM hospital, Coimbatore, Tamil Nadu, India with chest pain and respiratory distress for last 6 hours during my fellowship training in that hospital. ECG showed acute antero-septal MI. The transthoracic echocardiogram revealed severe left ventricular dysfunction with moderate mitral regurgitation...

A 36-year-old pregnant woman with a history of rheumatic heart disease and prior aortic valve replacement and mitral valve repair presented to an outside hospital with severe aortic stenosis. The patient had a cardiac arrest upon labor induction and underwent a transcatheter aortic valve replacement (TAVR), which dislodged two days later. Five months later, the patient underwent removal of the dislodged TAVR and a Ross procedure at the authors' institution. The patient was stable upon discharge, with minimal aortic and pulmonary regurgitation...

The case is described of a successful MitraClip procedure performed on an 88-year-old patient with severe mitral regurgitation (MR), five years after she had undergone mitral valve repair using the Alfieri surgical procedure. It is suggested that the MitraClip procedure is an option in patients with severe MR persisting after the Alfieri procedure. Video 1: Transesophageal echocardiography before the MitraClip procedure. Severe mitral regurgitation with preserved left ventricular systolic function. The main regurgitant jet originates from the medial commissure...

A 79-year-old woman with a history of ischemic dilated cardiomyopathy, severely depressed left ventricular ejection fraction and significant mitral regurgitation (MR) was admitted to the authors´ institution for percutaneous mitral valve repair. Transesophageal echocardiography (TEE) revealed the presence of a posterior mitral cleft at the P2 level, causing a trileaflet mitral valve that contributed significantly to the regurgitant jet. The procedure was performed under general anesthesia and guided by real-time three-dimensional TEE...

BACKGROUND: Segmental analysis of diseased mitral valves is important to predict a successful surgical valve repair. An assessment was made of the comparative accuracy of intraoperative three-dimensional (3D) and two-dimensional (2D) transesophageal echocardiography (TEE) in the evaluation of mitral valve lesions when compared with intraoperative surgical segmental analysis. METHODS: A total of 42 consecutive patients (12 females, 30 males; mean age 70.5 ± 14 years) with severe mitral valve regurgitation due to degenerative disease and who underwent mitral valve repair was enrolled in the study...

Bartonella spp. are emerging pathogens that are reported as the cause of blood culture-negative endocarditis ( BCNE). However, echocardiographic features and assessment of this endocarditis remains unclear. Four patients with B. henselae endocarditis were identified. All patients had underlying cardiac conditions: rheumatic heart disease in three, congenital heart disease in one. Evidence of vegetations was found on the aortic valve in all patients with large, highly mobile vegetations and severely destroyed valves demonstrated by the transthoracic echocardiogram leading to severe aortic regurgitation and heart failure...

A rare case of mitral stenosis after mitral valve repair for non-rheumatic mitral regurgitation is presented. An 81-year-old woman who had undergone mitral valve repair using an annuloplasty ring 12 years earlier, was referred to our hospital because of dyspnea during exertion. As echocardiography revealed severe mitral stenosis, and redo surgery was carried out. During the surgery, fibrous tissue covered the annuloplasty ring and extended onto both leaflets of the mitral valve, which narrowed its orifice, by rendering the leaflets stiff and immobile...

Generally, anticoagulation therapy is not essential for patients who maintain sinus rhythm after mitral valvuloplasty. A 66-year-old woman who had undergone mitral valvuloplasty and maze procedure for treatment of mitral valve regurgitation and atrial fibrillation 4 years ago was diagnosed as having left atrial thrombosis despite maintenance of sinus rhythm on electrocardiography. Echocardiography showed narrow mitral valvular area(1.5 cm2), loss of A wave and a huge left atrium. Repeat surgery was performed to replace the mitral valve and to remove the thrombus...

A 72-year-old man was admitted to our hospital because of dyspnea. He had a history of cardiac resynchronization therapy for congestive heart failure due to dilated cardiomyopathy 6 months previously. Echocardiography revealed severe functional mitral regurgitation which had been mild 6 months before. Because medical treatment was ineffective, on-pump beating mitral valve replacement using a bioprosthesis was performed to prevent reperfusion injury. The patient was easily weaned from cardiopulmonary bypass with low-dose inotropic support and scheduled intra-aortic balloon pump...

BACKGROUND: Septal myectomy has been the mainstay of the surgical treatment of obstructive hypertrophic cardiomyopathy (HCM), however recently there is growing appreciation for associated mitral valve abnormalities that contribute to left ventricular outflow tract (LVOT) obstruction. In this study, we describe our experience with combined papillary muscle realignment (PMR) and septal myectomy for the treatment of obstructive HCM. METHODS: We identified 44 patients undergoing surgery for obstructive HCM whose anatomy was amenable to combined PMR and septal myectomy at our institution over a 20-month period...

BACKGROUND: Complex mitral valve disease can require surgical repair techniques that are challenging in a minimally invasive context and may expose patients to prolonged cardiopulmonary bypass and cross clamp times. Here, we review our simplified stepwise operative approach for the treatment of complex bileaflet mitral disease, on early outcomes and mid-term follow-up. METHODS: One hundred and forty consecutive patients with bileaflet disease underwent video-assisted right minimally invasive mitral valve repair at our surgical center between 2008 and 2016...

We demonstrate the technical aspects of a novel adjustable mitral ring. This new ring was implanted in a female landrace pig, for training and educational purposes. It can be adjusted independently in the P1, P2 and P3 segments, if required, to treat  recurrent mitral regurgitation, and this is a key difference to comparable devices. The first-in-man implantation is anticipated in the near future.

Annuloplasty ring repair is a common procedure for the correction of mitral valve regurgitation. Commercially available rings vary in dimensions and material properties. Annuloplasty ring suture dehiscence from the native annulus is a catastrophic yet poorly understood phenomenon that has been reported across ring types. Recognizing that sutures typically dehisce from the structurally weaker posterior annulus, our group is conducting a multi-part study in search of ring design parameters that influence forces acting on posterior annular sutures in the beating heart...

BACKGROUND: Mitral regurgitation in ischemic heart disease (IMR) is a strong predictor of outcome but until now, pathophysiology is not sufficiently understood and treatment is not satisfying. We aimed to systematically evaluate structural and functional mitral valve leaflet and annular characteristics in patients with IMR to determine the differences in geometric and dynamic changes of the MV between significant and mild IMR. METHODS: Thirty-seven patients with IMR (18 mild (m)MR, 19 significant (moderate+severe) (s)MR) and 33 controls underwent TEE...

OBJECTIVES: To assess the clinical characteristics, management, and outcomes of patients diagnosed with infective endocarditis (IE) after edge-to-edge mitral valve repair with the MitraClip device. BACKGROUND: Transcatheter edge-to-edge mitral valve repair has emerged as an alternative to surgery in high-risk patients. However, few data exist on IE following transcatheter mitral procedures. METHODS: Four electronic databases (PubMed, Google Scholar, Embase, and Cochrane Library) were searched for original published studies on IE after edge-to-edge transcatheter mitral valve repair from 2003 to 2017...

Transcatheter mitral valve replacement (TMVR) is a novel approach for treatment of severe mitral regurgitation. A number of TMVR devices are currently undergoing feasibility trials using both transseptal and transapical routes for device delivery. Overall experience worldwide is limited to fewer than 200 cases. At present, the 30-day mortality exceeds 30% and is attributable to both patient- and device-related factors. TMVR has been successfully used to treat patients with degenerative mitral stenosis (DMS) as well as failed mitral bioprosthesis and mitral repair using transcatheter mitral valve-in-valve (TMViV)/valve-in-ring (ViR) repair...
