Transcatheter mitral valve replacement: current status.

After aortic valve stenosis, mitral regurgitation (MR) is the second most common valvular disease, particulary affecting older patients. Optimal medical treatment within the context of heart failure therapy is the favored first-line therapy for secondary MR. If symptoms persist despite optimal medical therapy, surgical or transcatheter mitral valve repair is indicated (recommendation class IIb). In contrast, surgical treatment is essential for patients with symptomatic primary MR and left-ventricular ejecti...


Successful mitral valve repair for isolated mitral regurgitation in a child with Williams syndrome.

Williams syndrome is a genetic disorder associated with various cardiovascular abnormalities, most commonly supravalvar aortic stenosis and peripheral pulmonary stenosis. However, isolated severe mitral regurgitation necessitating surgical intervention is extremely rare. Here, we present the case of a 14-year-old child with Williams syndrome and isolated severe mitral regurgitation who underwent successful mitral valve repair.

Repair versus replacement of mitral valves in cases of severe rheumatic mitral stenosis: mid-term clinical outcomes.

We compared and analyzed differences between repair vs. replacement of mitral valves on severe rheumatic mitral stenosis by looking at mid-term clinical outcomes.


Left Ventricular Stroke Work Index Associated with Outcome After Mitral Valve Surgery for Functional Regurgitation in Non-Ischemic Dilated Cardiomyopathy.

The indications for mitral valve surgery in patients with advanced non-ischemic dilated cardiomyopathy and functional mitral regurgitation are still unclear. We reviewed our experience of mitral valve surgery in such patients and explored factors that were predictive of outcomes. Fifty-three consecutive patients with non-ischemic dilated cardiomyopathy and an ejection fraction

Tp-e interval and Tp-e/QT ratio and their association with left ventricular diastolic dysfunction in Fabry disease without left ventricular hypertrophy.

In the early stage of the Fabry disease, diastolic dysfunction can occur before left ventricular hypertrophy (LVH). Cardiovascular complications, most of which are seen as malignant arrhythmias and heart failure, are the leading causes of death in these patients. The aim of the present study was to assess repolarization parameters of Fabry patients in early stage (without LVH) and to show the relationship between these parameters and left ventricular diastolic dysfunction.

Assessment of Prognostic Value of Left Ventricular Global Longitudinal Strain for Early Prediction of Chemotherapy-Induced Cardiotoxicity: A Systematic Review and Meta-analysis.

Echocardiographic left ventricular global longitudinal strain (GLS) detects early subclinical ventricular dysfunction and can be used in patients receiving potentially cardiotoxic chemotherapy. A meta-analysis of the prognostic value of GLS for cancer therapy-related cardiac dysfunction (CTRCD) has not been performed, to our knowledge.

Rapid progression of aortic and mitral stenosis in a patient with AA amyloidosis: a case report.

Aortic stenosis is a common finding in cardiac amyloidosis (CA). Younger patients often remain asymptomatic. If unrecognized, this can lead to serious complications such as heart failure. Progression of aortic stenosis can be accelerated in patients with chronic kidney disease and need for dialysis. Perioperative risk in these patients is often high due to the underlying systemic disease.

Prognostic role of diastolic dysfunction in patients undergoing transcatheter aortic valve replacement.

Prior studies have shown that left ventricular diastolic dysfunction (DD) is associated with increased mortality after surgical aortic valve replacement but studies on transcatheter aortic valve replacement (TAVR) are limited and have not taken into account mitral annular calcification (MAC), which limits the use of mitral valve annular tissue Doppler imaging. We performed a single-center retrospective analysis to better evaluate the role of baseline DD on outcomes after TAVR.

Atrial fibrillation and successful transcatheter mitral valve repair using MitraClip.

Ledwoch and colleagues demonstrated in their article entitled "Impact of transcatheter mitral valve repair using MitraClip on right ventricular remodeling" that right ventricular function improved in most of the patients following MitraClip implantation whereas 20% of them experienced worsening of right ventricular function which associated with worse prognosis, despite the latter cohort achieved comparable improvement in the mitral regurgitation. Given most of the latter cohort had atrial fibrillation, agg...

Clinical significance of early-diastolic tissue velocity imaging of lateral mitral annulus for prognosis of nonischemic left ventricular dysfunction.

We explored the potential of tissue velocity imaging (TVI) for prognosis of nonischemic left ventricular (LV) dysfunction (LVD).

Hemodynamics rounds: Hemodynamics of mitral valve interventions.

Mitral valvulopathy presents as regurgitation, stenosis, or mixed disease and can occur in both native and prosthetic valves. Such disease develops in conjunction with pathophysiologic changes in the left atrium (LA) and drives changes in LA compliance, pressure, and thus clinical syndromes. With advances in the understanding and treatment of structural heart disease and in the setting of higher-risk patient populations, less-invasive transcatheter approaches have become increasingly commonplace in the trea...

An Appraisal of the Association of Clinical Outcomes With the Severity of Regurgitant Volume Relative to End-Diastolic Volume in Patients With Secondary Mitral Regurgitation.

Two randomized clinical trials of transcatheter edge-to-edge mitral valve repair in patients with secondary mitral regurgitation (the Multicentre Randomized Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients With Severe Secondary Mitral Regurgitation [MITRA-FR] and the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation [COAPT]) report clinical outcome disparities that are largely unexplained. This appra...

Lithotripsy-Facilitated Mitral Balloon Valvuloplasty for Senile Degenerative Mitral Valve Stenosis.

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.

Cardiac inflammation and diastolic dysfunction in hypercholesterolemic rabbits.

Left ventricular diastolic dysfunction (LVDD) is present in more than 50% of patients suffering from heart failure. LVDD animal models are limited and its underlying mechanisms remain largely unknown. Aortic valve stenosis (AVS) may cause LVDD, and we recently reported LVDD in an AVS rabbit model. Here we aimed to develop a rabbit model of LVDD without AVS.

The strange case of congenital mitral stenosis in an adult man with cor triatriatum.

We report the case of a 74-year-old male, with a medical history of cor triatriatum, admitted with a 10-day history of intermittent fever. Three sets of blood cultures were positive for Providencia rettgeri. Transthoracic and transesophageal echocardiogram excluded infective endocarditis, but revealed a congenital accessory tissue adhering to the mitral valve, causing supravalvular mitral stenosis. Cor triatriatum sinistrum is a rare congenital cardiac anomaly, even more uncommon in adults, and quite except...

Revascularization in left ventricular dysfunction: an update.

The purpose of this article is to provide an overview of revascularization in patients with coronary artery disease (CAD) and left ventricular dysfunction (LVD).

Echocardiographic assessment of right heart size and function in dogs with pulmonary valve stenosis.

We sought to determine the prevalence and clinical significance of right heart remodeling and right ventricular (RV) dysfunction in dogs with pulmonary valve stenosis (PS). We also sought to evaluate repeatability of several measurements of severity of PS, right heart size, and RV function in dogs with PS.

Subclinical biventricular systolic dysfunction in patients with systemic sclerosis.

Silent myocardial involvement is associated with poor prognosis in patients with systemic sclerosis (SSc). Here we aimed to evaluate the subclinical left ventricular (LV) and right ventricular (RV) systolic dysfunction in patients with SSc without any cardiovascular diseases, by using both strain imaging methods, speckle tracking echocardiography (STE) and real-time 3D echocardiography (RT3DE).

Familial occurrence of mitral regurgitation in patients with mitral valve prolapse undergoing mitral valve surgery.

Initial studies have suggested the familial clustering of mitral valve prolapse, but most of them were either community based among unselected individuals or applied non-specific diagnostic criteria. Therefore little is known about the familial distribution of mitral regurgitation in a referral-type population with a more severe mitral valve prolapse phenotype. The objective of this study was to evaluate the presence of familial mitral regurgitation in patients undergoing surgery for mitral valve prolapse, ...

Urgent mechanical circulatory support and transcatheter mitral valve repair for refractory hemodynamic compromise.

Patients presenting with hemodynamic instability attributable to left ventricular systolic dysfunction and concomitant severe mitral regurgitation (MR) are increasingly recognized and pose complex management challenges. Surgical therapy is typically precluded owing to prohibitive mortality. The role of percutaneous mechanical circulatory support in such cases is well established; however, such interventions may be neither sufficient to achieve optimal stability nor prove definitive. The advent of novel cath...

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.

Mitral Valve Prolapse, Ventricular Arrhythmias, and Sudden Death.

Despite a 2% to 3% prevalence of echocardiographically defined mitral valve prolapse (MVP) in the general population, the actual burden, risk stratification, and treatment of the so-called arrhythmic MVP are unknown. The clinical profile is characterized by a patient, usually female, with mostly bileaflet myxomatous disease, mid-systolic click, repolarization abnormalities in the inferior leads, and complex ventricular arrhythmias with polymorphic/right bundle branch block morphology, without significant re...

Right ventricular diastolic dysfunction in patients with obstructive sleep apnea syndrome.

This study aimed to assess right ventricular (RV) diastolic dysfunction in patients with obstructive sleep apnea syndrome (OSAS) using velocity vector imaging (VVI) and to evaluate the application of VVI technology.

Left Ventricular Strain and Rotation in Patients with Dilated Cardiomyopathy and Severe Systolic Dysfunction.

In dilated cardiomyopathy (DCM) left ventricular (LV) strain and twist are significantly decreased. However, the rate of attenuation has not been investigated well in patients with varying degrees of systolic dysfunction.
