Genetic relevance and determinants of mitral leaflet size in hypertrophic cardiomyopathy.

Whether mitral leaflet elongation is a primary phenotype of hypertrophic cardiomyopathy (HCM) is controversial. We investigated the genetic relevance and determinants of mitral leaflet size by performing extensive gene analyses in patients with HCM.

A Floating Stitch on the Anterior Mitral Leaflet Can Eliminate Systolic Anterior Motion in Hypertrophic Obstructive Cardiomyopathy.

Reducing the SAM is a key way of resolving LVOT obstruction in surgery for HOCM. We developed a new technique using a floating stitch on the anterior mitral leaflet (AML). It is applied just to the middle of the tip of the AML and fixed to the annuloplasty ring at the middle of the posterior annulus. The AML is prevented from touching the interventricular septum and SAM can theoretically be solved.

Sinus of Valsalva aneurysm protruding into the mitral anterior leaflet causing dyspnea: A CARE-compliant case report.

Sinus of Valsalva aneurysm (SVA) protruding into the mitral anterior leaflet is an extremely rare clinical condition; herein, we present a case of unruptured noncoronary SVA protruding into the mitral anterior leaflet.

Long-term results after reconstruction of a new annulus in heavily calcified mitral annulus.

In 2009 our group described a new surgical technique for patients with severe mitral valve calcification undergoing mitral valve surgery. This technique creates a new mitral annulus with plication of the mitral leaflet and the atrial wall. Our objective is to report the long-term results of the experience at our institution.

Left Ventricular Outflow Tract Obstruction from Preserved Leaflet after Mitral Valve Replacement.

Left ventricular outflow tract obstruction (LVOTO) can be caused by multiple factors. One of rare causes of LVOTO is preserved anterior mitral valve leaflet and chordal apparatus after mitral valve replacement. Here, we describe a case of a patient who presented with worsening chronic congestive heart failure secondary to LVOTO from systolic anterior motion of residual native anterior mitral leaflet. This was surgically corrected by excision of anterior leaflet and chordal apparatus through the aortic root.

Hypoplasia of the posterior mitral leaflet diagnosed in adulthood.

Percutaneous Approaches to the Treatment of Mitral Leaflet Perforation and to Residual Regurgitation After Transcatheter Edge-to-Edge Mitral Valve Repair.

Mitral valve disease becomes more prevalent as the population ages. As the number of percutaneous mitral valve interventions expands, obscure clinical scenarios may emerge and challenge conventional treatment algorithms. Strategies for dealing with complex repairs build on prior experience in mitral perivalvular leak repair. Cases using nitinol- and expanded polytetrafluoroethylene-based devices are used to treat mitral regurgitation in cases of focal mitral perforations and leaks between previously placed ...

Midterm results of Mitral Valve Repair with Pericardial leaflet augmentation: A Single center experience.

In certain pathologies, mitral valve repair is complicated by a paucity of tissue caused by fibrosis or destruction. Utilization of autologous pericardium for leaflet augmentation may be the only option to repair these valves. We present the midterm results of mitral valve leaflet augmentation with glutaraldehyde fixed autologous pericardium. 130 consecutive patients undergoing mitral valve repair with glutaraldehyde fixed pericardial augmentation of leaflets were followed up clinically and by echocardiogra...

Mitral valve repair for posterior leaflet prolapse: Long-term comparison of loop implantation vs resection.

Resection (triangular or quadrangular) is considered the gold standard for the treatment of posterior leaflet prolapse and loop implantation a more recent alternative. We aimed to compare the long-term outcomes of triangular or quadrangular resection vs loop implantation.

A challenging mitral valve anatomy for percutaneous repair with MitraClip: cleft posterior leaflet.

Papillary muscle intervention vs mitral ring annuloplasty in ischemic mitral regurgitation.

The main pathophysiological factor of chronic ischemic mitral regurgitation (MR) is the outward displacement of the papillary muscles (PMs) leading to leaflet tethering. For this reason, papillary muscle intervention (PMI) in combination with mitral ring annuloplasty (MRA) has recently been introduced into clinical practice to correct this displacement, and to reduce the recurrence of regurgitation.

Long Term Performance of Fresh Autologous Pericardium for Mitral Valve Leaflet Repair.

Glutaraldehyde-fixed autologous or bovine pericardial patches used for mitral valve leaflet reconstruction have been associated with late calcification. Fresh autologous pericardium (FAP) may be a durable alternative.

Functional and Degenerative Mitral Regurgitation: One Ring Fits All?

 Three-dimensional saddle-shaped annuloplasty rings have been shown to create a larger surface of leaflet coaptation in mitral valve repair (MVR) for functional mitral regurgitation (FMR) and degenerative mitral regurgitation (DMR) which may increase repair durability. For the first time, this study reports mid-term results after MVR for DMR and FMR using a rigid three-dimensional ring (Profile 3D, Medtronic).

Mechanical effects of MitraClip on leaflet stress and myocardial strain in functional mitral regurgitation - A finite element modeling study.

MitraClip is the sole percutaneous device approved for functional mitral regurgitation (MR; FMR) but MR recurs in over one third of patients. As device-induced mechanical effects are a potential cause for MR recurrence, we tested the hypothesis that MitraClip increases leaflet stress and procedure-related strain in sub-valvular left ventricular (LV) myocardium in FMR associated with coronary disease (FMR-CAD).

Echocardiography and Correction of Mitral Regurgitation: An Unbreakable Link.

Degenerative mitral valve (MV) disease causing mitral regurgitation (MR) is the most common organic valve pathology and is classified based on leaflet motion. MV repair is indicated as the preferred technique (Class I indication) when the results are expected to be durable. Therefore, a detailed and systematic evaluation of MV apparatus is pivotal in allowing the proper surgical planning, as well as the screening for trans catheter-based treatment when surgery is not indicated.

Mitral valve replacement with the 15-mm mechanical valve: a 20-year multi-center experience.

The aim of this study was to evaluate early and long-term outcomes (mortality and prosthetic valve replacement) after mitral valve replacement with the 15-mm St. Jude Medical prosthesis.

The REDUCE FMR Trial: A Randomized Sham-Controlled Study of Percutaneous Mitral Annuloplasty in Functional Mitral Regurgitation.

This study sought to evaluate the effects of the Carillon device on mitral regurgitation severity and left ventricular remodeling.

Minithoracotomy and Beating Heart Strategy for Mitral Surgery in Secondary Mitral Regurgitation.

 In patients with secondary mitral regurgitation (MR) associated with low ejection fraction or previous heart surgery, minimally invasive mitral valve surgery without aortic cross-clamp (MIMVS-WAC) has shown promising results. We report our experience for this strategy in our centers.

Operator Experience and Procedural Results of Transcatheter Mitral Valve Repair in the United States.

Transcatheter mitral valve repair (TMVr) for the treatment of mitral regurgitation (MR) is a complex procedure that requires development of a unique skillset.

Renal outcomes of neonates with early presentation of posterior urethral valves: a 10-year single center experience.

Evaluate renal outcomes and early predictive factors in infants with congenital posterior urethral valves who required catheter or surgical urinary tract decompression within the first 7 days of life.

Automated Implantation of Artificial Mitral Chords: Preliminary Results from the Feasibility Trial.

A novel chordal system enables automated implantation of artificial mitral chords to treat mitral regurgitation (MR). This paper summarizes the "first-in-man" initial clinical results.

Reduced Leaflet Motion after Transcatheter Aortic-Valve Replacement.

Subclinical leaflet thickening and reduced leaflet motion of bioprosthetic aortic valves have been documented by four-dimensional computed tomography (CT). Whether anticoagulation can reduce these phenomena after transcatheter aortic-valve replacement (TAVR) is not known.

Cardiolipin Preferentially Partitions to the Inner Leaflet of Mixed Lipid Large Unilamellar Vesicles.

Cardiolipin (CL), an anionic phospholipid constituting 20% of the inner mitochondrial membrane (IMM) of eukaryotes, stabilizes electron transport chain (ETC) complexes and is a signaling agent in the early stages of apoptosis. For apoptosis, CL moves from the inner to the outer leaflet of the IMM via a poorly understood mechanism. Relative to cylindrically-shaped lipids like dioleoylphosphatidylcholine (DOPC) and dioleoylphosphatidylglycerol (DOPG), cone-shaped CL should prefer concave surfaces of lipid bil...

Early and long-term results of surgery for secondary mitral regurgitation with a damaged heart.

Surgery for secondary mitral regurgitation is still controversial, especially when the left ventricle is damaged. The Mitra Clip has been shown to be safe and effective for certain patient groups but does not offer superior control of mitral regurgitation compared with the surgery. If performed safely, the surgery can provide greater benefits over the long-term. The objective of this study was to retrospectively investigate the early and long-term results of mitral valve surgery for secondary mitral valve r...

Utilization of intra-aortic balloon pump to allow MitraClip procedure in patients with non-coapting mitral valve leaflets: a case series.

The MitraClip (MC) procedure was designed for high-risk surgical patients with severe mitral regurgitation (MR). Some patients do not meet the required anatomical criteria due to advanced left ventricular remodelling and mitral annular dilatation leading to leaflet tethering and insufficient coaptation surface. Theoretically, 'temporary remodelling' of the mitral valve apparatus by pharmacological and/or mechanical support using intra-aortic balloon pump (IABP) could improve leaflets coaptation.
