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...
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.
We compared and analyzed differences between repair vs. replacement of mitral valves on severe rheumatic mitral stenosis by looking at mid-term clinical outcomes.
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
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.
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.
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.
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.
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...
We explored the potential of tissue velocity imaging (TVI) for prognosis of nonischemic left ventricular (LV) dysfunction (LVD).
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...
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...
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.
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.
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...
The purpose of this article is to provide an overview of revascularization in patients with coronary artery disease (CAD) and left ventricular dysfunction (LVD).
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.
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).
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, ...
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...
This study sought to evaluate the effects of the Carillon device on mitral regurgitation severity and left ventricular remodeling.
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...
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.
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.
