Mitral valve prolapse (MVP) is a common condition that affects 2%-3% of the general population. MVP is thought to include syndromic forms such as Marfan syndrome and non-syndromic MVP, which is the most frequent form. Myxomatous degeneration and fibroelastic deficiency (FED) are regarded as two different forms of non-syndromic MVP. While FED is still considered a degenerative disease associated with ageing, frequent familial clustering has been demonstrated for myxomatous MVP. Familial and genetic studies led to the recognition of reduced penetrance and large phenotypic variability, and to the identification of prodromal or atypical forms as a part of the complex spectrum of the disease...

OBJECTIVE: To assess stroke/systemic embolism, major bleeding and other outcomes, and treatment effect of apixaban versus warfarin, in patients with atrial fibrillation (AF) and different types of valvular heart disease (VHD), using data from the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial. METHODS: There were 14 793 patients with known VHD status, categorised as having moderate or severe mitral regurgitation (MR) (n=3382), aortic regurgitation (AR) (n=842) or aortic stenosis (AS) (n=324); patients with moderate or severe mitral stenosis were excluded from the trial...

OBJECTIVES: This study evaluates the impact of untreated preoperative severe mitral valve regurgitation (MR) on outcomes after left ventricular assist device (LVAD) implantation. METHODS: Of the 234 patients who received LVAD therapy in our centre during a 6-year period, we selected those who had echocardiographic images of good quality and excluded those who underwent mitral valve replacement prior to or mitral valve repair during LVAD placement. The 128 patients selected were divided into 2 groups: Group A with severe MR (n = 65) and Group B with none to moderate MR (n = 63, 28 with moderate MR)...

AIM: To study the changes of mitral valve (MV) in patients with nonvalvular atrial fibrillation (NVAF)-related mitral regurgitation (MR) and the relationship between MV parameters and the enlarged left atrium (LA). MATERIALS AND METHODS: A total of 43 patients with NVAF were divided into two groups: (1) the MR1 group with mild MR and (2) the MR2 group with moderate-to-severe MR. Real time 3D transesophageal echocardiography (TEE) was performed to detect the structure of MV...

OBJECTIVE: Hematopoietic-derived cells have been reported in heart valves but remain poorly characterized. Interestingly, recent studies reveal infiltration of leukocytes and increased macrophages in human myxomatous mitral valves. Nevertheless, timing and contribution of macrophages in normal valves and myxomatous valve disease are still unknown. The objective is to characterize leukocytes during postnatal heart valve maturation and identify macrophage subsets in myxomatous valve disease...

Caseous calcification of the mitral annulus (CCMA) is considered a rare variant of mitral annular calcification (MAC) due to caseous transformation of the inner material and prevalence of CCMA, about 0.63% of all MAC cases and 0.06%-0.07% of the population. The precise pathophysiology of CCMA is still unknown. It is a chronic degenerative disorder common in the elderly, particularly in women. Caseous calcification of the mitral annulus (CCMA) is a soft peri-annular extensive calcification, resembling cardiac tumors, abscesses, vegetation, or calcified thrombus, which is composed of an admixture of calcium, fatty acids, and cholesterol with a toothpaste-like texture...

We report a case of catheter-based edge-to-edge mitral valve repair in a teenage male patient with non-ischaemic cardiomyopathy to improve pulmonary hypertension secondary to severe functional mitral regurgitation (FMR) to defer anticipated heart transplantation. A 19-year-old patient with previous history of fulminant myocarditis followed by markedly left ventricular dysfunction presented with severe mitral regurgitation 3 years after initial recovery. Slightly over time, deterioration of FMR was associated with gradual increase in pulmonary artery pressures despite optimal medical therapy...

BACKGROUND: We assessed the mitral annular motion after mitral valve repair with the Sorin Memo 3D® (Sorin Group Italia S.r.L., Saluggia, Italy), which is a unique complete semirigid annuloplasty ring intended to restore the systolic profile of the mitral annulus while adapting to the physiologic dynamism of the annulus, using transesophageal real-time three-dimensional echocardiography. METHODS: 17 patients (12 male; mean age 60.4 ± 14.9 years) who underwent mitral annuloplasty using the Memo 3D ring were investigated...

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.

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...

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...
