Assessment of right ventricular dysfunction in patients with mitral stenosis: A speckle tracking study.

Although it is affected at an early stage, there is a lack of studies investigating right ventricular (RV) function in patients with mitral stenosis (MS). We aimed to investigate the correlation between conventional echocardiographic variables and tricuspid annular plane systolic excursion (TAPSE), used as an indicator of RV dysfunction.

Hemodynamics and Prognostic Impact of Concomitant Mitral Stenosis in Patients Undergoing Surgical or Transcatheter Aortic Valve Replacement for Aortic Stenosis.

Mitral stenosis frequently coexists in patients with severe aortic stenosis. Mitral stenosis severity evaluation is challenging in the setting of combined aortic stenosis and mitral stenosis because of hemodynamic interactions between the 2 valve lesions. The impact of aortic valve replacement (AVR) for severe aortic stenosis on mitral stenosis is unknown. This study aimed to assess the effect of AVR on mitral stenosis hemodynamics and the clinical outcomes of patients with severe aortic stenosis with and w...

Predictors of Left Ventricular Dysfunction after Surgery for Degenerative Mitral Regurgitation.

This study was performed to determine if strain can supplement the ability of left ventricular ejection fraction (LVEF) to predict post-op ventricular dysfunction in patients undergoing mitral valve (MV) surgery for degenerative mitral regurgitation (DMR).

Rapid improvement in right ventricular free wall longitudinal strain measures after successful percutaneous mitral commissurotomy.

Percutaneous mitral commissurotomy (PMC) is currently the treatment of choice for patients with symptomatic mitral stenosis (MS) that have favorable valvular characteristics. We aimed to evaluate the effect of PMC on the longitudinal strain of the right ventricular (RV) free wall in patients with severe MS.

Degenerative mitral valve stenosis: Diagnosis and management.

Mitral stenosis (MS) is a common valvular disease characterized by narrowing of the mitral valve orifice and a reduction in mitral valve area (MVA). While rheumatic MS (RMS) is frequently encountered in young individuals in developing countries, degenerative MS (DMS) is seen in the elderly in developed countries and its prevalence is increasing. DMS is usually a late presentation of mitral annular calcification (MAC). Accurate assessment of MVA in patients with MAC is challenging due to the alterations in t...

Association between left ventricular diastolic function and right ventricular function and morphology in asymptomatic aortic stenosis.

Aortic stenosis (AS) is a progressive disease in which left ventricular (LV) diastolic dysfunction is common. However, the association between diastolic dysfunction and right ventricular (RV) loading conditions and function has not been investigated in asymptomatic AS patients.

Results of left ventricular reconstruction with and without mitral valve surgery.

This study aims to compare the mid-term outcomes of left ventricular reconstruction with those of left ventricular reconstruction plus mitral valve surgery in patients with left ventricular aneurysm due to anterior myocardial infarction and moderate mitral regurgitation.

Usefulness of 3-Tesla Cardiac Magnetic Resonance to Detect Mitral Annular Disjunction in Patients With Mitral Valve Prolapse.

Mitral annulus disjunction (MAD) is characterized by a separation between the atrial wall mitral junction and the left ventricular (LV) free wall. Little is known regarding cardiac magnetic resonance (CMR) performance to detect MAD and its prevalence in mitral valve prolapse (MVP). Based on 89 MVP patients (63 women; mean age 64 ± 13) referred for CMR assessment of MR, either from myxomatous mitral valve disease (MMVP) (n = 40; 45%) or fibroelastic disease (n = 49; 55%), we sought to assess the fre...

Measurement of mitral valve area in patients with mitral stenosis by 3D echocardiography: A comparison between direct planimetry on 3D zoom and 3D quantification.

Measurement of the mitral valve area (MVA) in patients with mitral stenosis (MS) by 3D echocardiography (3DE) is usually done via 3D quantification (3DQ). The present study on patients with severe MS sought to evaluate the agreement regarding the MVA measurement between 3DQ and direct planimetry on 3D zoom and also between 3DE and 2DE.

Echocardiographic assessment of mitral regurgitation.

Mitral regurgitation (MR) is one of the most frequent indications for valve surgery in developed countries, and echocardiographic assessment is an essential tool to evaluate its etiologies, severity, and therapeutic indications. The mitral valve apparatus is a complex structure composed of several parts: apart from the mitral valve leaflets and annulus, it also includes the chordae tendineae, papillary muscles, and left ventricular (LV) wall. MR can be caused not only by organic changes of the mitral valve ...

Surgical management of mitral annular calcification.

The aim of the article is to discuss different therapeutic options for patients with severe mitral valve dysfunction because of mitral annular calcification (MAC), including mitral valve repair, conventional mitral valve replacement, percutaneous transcatheter mitral valve replacement (TMVR), and hybrid procedures.

Effect of Pulmonary Hypertension on Clinical Outcomes in Patients with Rheumatic Mitral Stenosis.

Long-term outcomes of mitral valve replacement (MVR) recipients with pulmonary hypertension (PH) remain unclear. We determined the effect of concomitant PH on the clinical outcomes and late-onset progression of tricuspid regurgitation (TR) following MVR for rheumatic mitral stenosis.

Echocardiography vs cardiac magnetic resonance imaging assessment of the systemic right ventricle for patients with d-transposition of the great arteries status post atrial switch.

Patients with Dextro-transposition of the great arteries status post atrial switch (dTGA s/p atrial switch) are "at-risk" for systemic right ventricular (RV) dysfunction. Due to complex RV geometry, echocardiography (Echo) does not allow accurate determination of ejection fraction (EF), but cardiac magnetic resonance imaging (CMR) allows quantitative right ventricular assessment. Measures of ventricular deformation may be precursors to global ventricular dysfunction. The primary aim of this study was to cha...

Multimodality Imaging for the Assessment of Severe Aortic Stenosis.

Aortic stenosis is the most common type of valvular heart disease. Aortic stenosis is characterized both by progressive valve narrowing and the left ventricular remodeling response that ensues. In aortic stenosis, therapeutic decision essentially depends on symptomatic status, stenosis severity, and status of left ventricular systolic function. Imaging is fundamental for the initial diagnostic work-up, follow-up, and selection of the optimal timing and type of intervention. Noninvasive imaging has played a ...

Does isolated mitral annular calcification in the absence of mitral valve disease affect clinical outcomes after transcatheter aortic valve replacement?

Mitral annular calcification (MAC) has been associated with adverse outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) but has been investigated in isolation of co-existent mitral regurgitation or mitral stenosis, which may represent important confounders. This study sought to investigate the effect of MAC with and without concomitant mitral valve disease (MVD) on clinical outcomes in patients treated with TAVR.

The Choice of Treatment in Ischemic Mitral Regurgitation with Reduced Left Ventricular Function.

Ischemic mitral regurgitation is a condition characterized by mitral insufficiency secondary to an ischemic left ventricular.Primarily, the pathology is the result of perturbation of normal regional left ventricular geometry combined with adverse remodeling.We present a comprehensive review of contemporary surgical, medical, and percutaneous treatment options for ischemic mitral regurgitation, rigorously examined by current guidelines and literature.

Previously implanted mitral surgical prosthesis in patients undergoing transcatheter aortic valve implantation: Procedural outcome and morphologic assessment using multidetector computed tomography.

Transcatheter aortic valve implantation (TAVI) in the presence of a preexisting mitral prosthesis is challenging and its influence on the morphology of mitral prosthesis and the positioning of transcatheter heart valve (THV) is unknown. We assessed the feasibility of TAVI for patients with preexisting mitral prostheses, its influence on mitral prosthesis morphology, and the positional interaction between a newly implanted THV and mitral prosthesis using serial multidetector computed tomography (MDCT). Thirt...

Evaluation of Chronic Total Occlusion Recanalization: A Physiologic Assessment Perspective by Dynamic Exercise Tests.

Chronic total occlusion (CTO) recanalization and its effects on left ventricular function and patient outcomes has intrigued the interventional community over the last several years. Now that there is plenty of knowledge and experience on "how to treat" the lesion, another scientific effort should focus on "when to treat" the lesion. Physiologic assessment has altered the way we treat coronary artery stenosis to improve cardiovascular outcomes. We tend to assess the effects of CTO recanalization by evaluati...

Mitral Valve Surgery in the First Year of Life.

Data are limited on outcomes associated with mitral valve surgery in infants. Prior studies report high mortality and increased risk for late cardiac failure particularly for those with mitral stenosis. We sought to evaluate outcomes in patients with mitral stenosis (MS) or regurgitation (MR) who had mitral valvuloplasty or replacement in the first year of life. A retrospective analysis of all patients in a single institution who underwent mitral valvuloplasty or replacement in their first year of life from...

Impact of transcatheter mitral valve repair on ventricular arrhythmias.

Patients with heart failure and severe mitral regurgitation (MR) have a poor prognosis and carry an increased risk for ventricular arrhythmias. The present study evaluates the impact of transcatheter mitral valve repair using the MitraClip on the potential reduction of ventricular arrhythmias.

Circulating secretoneurin concentrations in patients with moderate to severe aortic stenosis.

Secretoneurin (SN) concentrations provide important prognostic information in patients with myocardial dysfunction. Whether preoperative SN concentrations improve risk assessment in patients with moderate to severe aortic stenosis (AS) is unknown.

Novel Multiphase Assessment for Predicting Left Ventricular Outflow Tract Obstruction Before Transcatheter Mitral Valve Replacement.

This study proposes a physiologic assessment of left ventricular outflow tract obstruction (LVOTO) that accommodates changes in systolic flow and accounts for the dynamic neo-left ventricular outflow tract (LVOT).

The role of stress echocardiography in cardiovascular disorders.

Stress echocardiography is a safe, low-cost, widely available, radiation-free versatile imaging modality that is becoming increasingly recognized as a valuable tool in the assessment of coronary heart disease. In recent years, there has also been an increasing use of stress echocardiography in the assessment of non-ischaemic cardiac disease given its unique ability for simultaneous assessment of both functional performance and exercise-related noninvasive hemodynamic changes which can help guide treatment a...

Left ventricular remodeling after mini-mitral repair-does the complexity of mitral disease matter?

Degenerative mitral valve (MV) regurgitation (MR) is associated with left ventricular (LV) dilatation. Surgical treatment of MR has been shown to favorably affect LV remodeling. We prospectively compared the long-term echocardiographic outcomes of LV remodeling following mini-mitral repair for simple versus complex MV disease.

Baseline left ventricular diastolic dysfunction affects midterm mortality after transcatheter aortic valve implantation.

To determine whether preprocedural left ventricular (LV) diastolic dysfunction impairs midterm mortality after transcatheter aortic valve implantation (TAVI) for patients with severe aortic stenosis (AS), we performed a meta-analysis of currently available evidence.
