Mitral stenosis is a uncommon valvular lesion in the developed countries. Noninvasive evaluation is the first-line modality for assessment of mitral stenosis, however the noninvasive methods may have limitations in certain cases. Invasive hemodynamics can be used as adjunct tool for assessment of mitral stenosis in such difficult cases. Mitral valve using three-dimensional planimetry is a promising technique for assessment of mitral stenosis.

BACKGROUND: The aim of this retrospective study was to identify clinical, humoral and echocardiographic variables predicting rehospitalization and poor quality of life (QOL) in patients with reduced or mid-range ejection fraction heart failure. METHODS: From 2009 to 2012, 310 patients were admitted having signs and symptoms of heart failure with reduced ejection fraction. All the patients were followed by phone, calling the patients or the referring general practitioner...

BACKGROUND: Post ablation reentrant ATs depend upon conducting isthmuses bordered by scar. Bipolar voltage maps highlight scar as sites of low voltage, but the voltage amplitude of an electrogram depends upon the myocardial activation sequence. Furthermore, a voltage threshold that defines atrial scar is unknown. We used Ripple Mapping (RM) to test whether these isthmuses were anatomically fixed between different activation vectors and atrial rates. METHODS: We studied post-AF ablation ATs where > 1 rhythm was mapped...

OBJECTIVES: Following mitral valve repair for Barlow's disease, recurrent mitral regurgitation (MR) is believed to occur frequently and is mainly attributed to disease progression. METHODS: Between January 2000 and December 2015, 180 patients (40% women, mean age 58.7 ± 13.5 years) with Barlow's disease underwent mitral valve repair. To provide a longitudinal assessment of mitral valve repair durability, a multistate model for interval-censored observations (4 states: 1, Grade 0/1+ MR; 2, Grade 2+ MR; 3, Grade 3+/4+ MR; 4, reintervention/death) was developed...

Dextrocardia with situs solitus and severe mitral regurgitation is a rare clinical presentation which posse a surgical challenge and requires specific preoperative planning. A 54-year-old women with this anatomy, multiple thoracic procedures, and severe mitral valve regurgitation underwent successful mitral valve replacement with a 27-mm mechanical prosthesis through a left thoracotomy under ventricular fibrillation, on the basis of computed tomography findings. We emphasize the importance of preoperative planning and a surgical approach through a left thoracotomy and under ventricular fibrillation...

The majority of cardiac left ventricular aneurysms involve the anterior and/or apical wall. We present a case of a 50-year-old man with heart failure caused by a large inferolateral left ventricular aneurysm and associated mitral regurgitation, managed by aneurysmectomy, mitral valvuloplasty, and surgical revascularization.

A supramitral ring is a rare cause of mitral stenosis, while an isolated mitral valve cleft is a rare cause of congenital mitral regurgitation. Fortunately, both the lesions are known to have good outcomes after surgical correction. Although each is known to be associated with a variety of other structural heart defects, their coexistence has not been reported previously. We report a case of a three- and half-year-old boy detected to have a rare combination of supramitral ring producing severe mitral stenosis with a coexisting cleft in the anterior leaflet of mitral valve causing severe mitral regurgitation...

PURPOSE OF REVIEW: As ventricular assist device (VAD) therapy in patients with advanced heart failure continues to grow, experience with concomitant valvular diseases present either before or after VAD implantation continues to accrue. In this review, we discuss recent data and current practice as it pertains to the subject of concomitant valvular disease in patients requiring VADs. RECENT FINDINGS: Persistent aortic valve closure has been identified as a potential contributor to aortic valve 'disuse atrophy' resulting in valve degeneration...

We report the case of a 38-year-old woman who was admitted for acute cerebral infarction linked to a cardiac calcified amorphous tumor (CAT) and related mitral annular calcification (MAC). The cardiac mass was removed, and mitral valve replacement surgery was performed. Pathological examination revealed an amorphous accumulation of degenerating material within both lesions, indicating that build-up of calcium along the mitral annulus and subsequent rupture of the fibrotic tissue may be involved in the initiation and progression of CAT...

Interferon gamma (IFN-γ) is a multifunctional cytokine that plays an important role in modulating almost all phases of the immune response and may be responsible for the increased valvular fibrosis and calcification in the pathogenesis of rheumatic heart disease (RHD). The aim of this study was to investigate the possible relationship between the IFN-γ +874 T/A polymorphism and the severity of valvular damage in the Turkish population. The IFN-γ genotypes were determined in 152 RHD patients and 151 healthy controls by ARMS-PCR...

BACKGROUND: Mitral regurgitation is a heterogeneous disease. Determining which patients derive optimal outcomes from transcatheter edge-to-edge mitral valve repair (TMVR) remains challenging. We sought to determine whether baseline mitral valve anatomic characteristics are predictive of left atrial pressure (LAP) changes during TMVR with MitraClip. METHODS AND RESULTS: Consecutive patients with severe mitral regurgitation undergoing TMVR (n=112) underwent continuous intraprocedural LAP monitoring and retrospective echocardiographic analysis for specific mitral anatomic characteristics...

Contemporary data on complications and resource utilization after atrial fibrillation (AF) ablation are limited. We evaluated rates and risk factors for procedural complication, rehospitalization, and emergency department visits after AF ablation. We identified all adult patients who underwent isolated AF ablation between 2010 and June 2014 in 2 large integrated health-care delivery systems and evaluated rates of acute inpatient complication, 30-day, and 1-year readmission and emergency evaluation. We used multivariable logistic regression to identify predictors of procedural complications, 30-day readmission, or 30-day emergency department evaluation...

BACKGROUND: This study aimed to investigate the mechanisms of acute changes in functional mitral regurgitation (FMR) by preload alterations. METHODS: Twenty-two consecutive patients with left ventricular ejection fraction <40% and at least mild FMR underwent transthoracic echocardiography. Passive leg lifting and sublingual administration of nitroglycerin were performed to alter preload. Mitral regurgitant volume (MRV) was assessed using the Doppler method. RESULTS: MRV changed in parallel with preload alterations...

Mitral paravalvular leak (PVL) remains a well-known complication after mitral valve replacement. Since the first report over 25 years ago, several catheter-based PVL closure techniques have been described. Most of these comprise of either an antegrade transseptal approach, or a retrograde transaortic or transapical approach. We herein report a novel percutaneous mitral PVL closure technique that was safely and successfully performed after failed attempt using a conventional antegrade approach.

INTRODUCTION: Rheumatoid arthritis (RA) represents a risk of non-fatal and cardiovascular events. The aim of the present study was to evaluate simultaneously left and right atrial and ventricular function, as well as arterial stiffness, in RA patients. METHODS: This cross-sectional study included 55 consecutive RA patients and 55 healthy age and gender-matched controls. Blood pressure and arterial stiffness were assessed in all participants, who also underwent a complete echocardiographic examination...
