OBJECTIVES: To evaluate the morphological reconstruction as assessed by 3D transoesophageal echocardiography after triangular resection and neochordal replacement in the treatment of posterior leaflet prolapse. METHODS: We retrospectively selected 46 patients with isolated posterior leaflet prolapse who were undergoing mitral valve repair using triangular resection ( n  = 20) and neochordal replacement ( n  = 26) techniques. Sixty patients without valvular heart disease were also included as the control group...

OBJECTIVES: This study aimed to assess mitral valve function after repair of ventricular septal defect (VSD) combined with mitral regurgitation (MR) in the mid-term follow-up period, to evaluate the clinical utility of simultaneous mitral valve repair (MVR). METHODS: From June 2005 to March 2014, 60 patients with VSD and MR underwent surgical treatment. After performing propensity score analysis (1:1) for the entire sample, 46 patients were selected and divided into 2 groups: those with VSD closure and MVR (VSD + MVR, 23 patients) and those with VSD closure without mitral valve intervention (VSD only, 23 patients)...

OBJECTIVES: Many surgical and interventional methods are available to restore patency for patients with degenerative severe mitral valve regurgitation. Leaflet resection and neochordoplasty, which both include ring annuloplasty, are the most frequently performed techniques for the repair of posterior mitral leaflet flail. It is unclear which technique results in the best haemodynamics. In this study, we investigated the effect of different mitral valve reconstruction techniques on mitral valve haemodynamics and diastolic transvalvular pressure gradient in an ex vivo porcine model...

BACKGROUND: Mutations in LMNA gene, encoding Lamin A/C, cause a diverse array of phenotypes, collectively referred to as laminopathies. The most common manifestation is dilated cardiomyopathy (DCM), occurring in conjunction with variable skeletal muscle involvement but without involvement of the coronary arteries. Much less commonly, LMNA mutations cause progeroid syndromes, whereby an early-onset coronary artery disease (CAD) is the hallmark of the disease. We report a hitherto unreported compound cardiac phenotype, dubbed as "non-syndromic cardiac progeria", in a young patient who carried a rare pathogenic variant in the LMNA gene and developed progressive degeneration of various cardiac structures, as seen in the elderly...

BACKGROUND: Despite the paucity of data available, orally administered angiotensin-converting enzyme (ACE) inhibitors are empirically used in horses with valvular regurgitation. OBJECTIVE: Evaluate the echocardiographic and hormonal changes in response to oral benazepril in horses with left-sided valvular regurgitation. STUDY DESIGN: Prospective, randomised double-blind, placebo-controlled trial. METHODS: Horses with mitral valve (MR) and/or aortic valve regurgitation (AR) received oral benazepril (n = 6) at a dosage of 1 mg/kg q 12h or a placebo (n = 5) for 28 days...

BACKGROUND: Ischemic mitral regurgitation (MR) is classically ascribed to functional restriction of normal leaflets, but recent studies have suggested post-myocardial infarction (MI) mitral valve (MV) leaflet fibrosis and thickening, challenging valve normality. Progression of leaflet thickness post-MI has not been studied. We hypothesized that excessive MV remodeling post-MI contributes to MR. Our objectives are to characterize MV changes after MI and relate them to MR. METHODS AND RESULTS: Three groups of 40 patients with serial echocardiograms over a mean of 23...

BACKGROUND: Mitral regurgitation in people without prior cardiac disease is considered a degenerative disease with no established risk factors for its prevention. We aimed to test the hypothesis that elevated systolic blood pressure (SBP) across its usual spectrum is associated with higher risk of mitral regurgitation. METHODS AND FINDINGS: We used linked electronic health records from the United Kingdom Clinical Practice Research Datalink (CPRD) from 1 January 1990 to 31 December 2015...

Takotsubo syndrome (TTS) was first described in 1991 as a rare, spontaneous and completely reversible left ventricular regional systolic dysfunction. Today the incidence of TTS is estimated at 2% in patients with an initial diagnosis of acute coronary syndrome (ACS). Notably, the incidence can be as high as 5.9 to 7.5% in female patients. TTS occurs predominantly in postmenopausal women, but both sexes may be affected, at any age. Acute chest pain or dyspnoea is a characteristic symptom of TTS, but initial presentation can also include more severe disease manifestation such as acute heart failure with pulmonary oedema or haemodynamic instability, especially in an in-hospital setting...

Aims: Balloon cryoablation is an accepted method of achieving pulmonary vein isolation for the treatment of atrial fibrillation. The relationship between blood flow in the atrium and cryo energy delivery to the tissue remains poorly understood. Methods and results: Controlled cryoablations were performed in vitro using a pulmonary vein phantom constructed from bovine muscle, providing a 20 mm vein ostium. A temperature sensor was mounted within the 'vein wall' at a 1 mm tissue depth...

M Cameli, E Incampo, S Mondillo
In chronic mitral regurgitation (MR) left atrium is one of the first cardiac structures that is involved in remodeling and ultrastructural changes for a progressive volume overload. Severe left atrial (LA) dilation on echocardiography and new onset of atrial fibrillation in asymptomatic patients with preserved Left Ventricular (LV) function, appeared as a Class IIb recommendation for consideration for surgical mitral valve repair in the actual guidelines. However, before atrial dilatation and dysfunction, several ultrastructural changes appear in the atrial muscle tissue that are difficult to identify with the standard echocardiography...

Percutaneous mitral valve repair with the MitraClip is an established treatment for patients with mitral regurgitation (MR) who are inoperable or at high risk for surgery. Atrial Fibrillation (AF) frequently coincides with MR, but only scarce data of the influence of AF on outcome after MitraClip is available. The aim of the current study was to compare the clinical outcome after MitraClip treatment in patients with versus without atrial fibrillation. Between January 2009 and January 2016, all consecutive patients treated with a MitraClip in 5 Dutch centers were included...

Individualized estimation of prognosis after cardiac resynchronization therapy (CRT) remains challenging. Our aim was to develop a multiparametric prognostic risk score (CRT-SCORE) that could be used for patient-specific clinical shared decision making about CRT implantation. The CRT-SCORE was derived from an ongoing CRT registry, including 1,053 consecutive patients (age 67 ± 10 years, 76% male). Using preimplantation variables, 100 multiple imputed datasets were generated for model calibration. Based on multivariate Cox regression models, cross-validated linear prognostic scores were calculated, as well as survival fractions at 1 and 5 years...

Aims: Aortic stenosis (AS) is the most frequent valvular disease in developed countries. As society grows older, the prevalence of AS increases. However, the real burden, current aetiology, severity distribution, and echocardiographic patterns of AS are not fully clear. The aim of the present study is to provide an accurate overall picture of AS, focusing on its epidemiology, aetiology, and echocardiographic features. Methods and results: A total of 29 502 consecutive echocardiograpies were prospectively included in this multicentre study...

Mitral regurgitation (MR) is frequent and associated with increased mortality and morbidity when severe. It may be caused by intrinsic valvular disease (primary MR) or ventricular deformation (secondary MR). Imaging has a critical role to document the severity, mechanism, and impact of MR on heart function as selected patients with MR may benefit from surgery whereas other will not. In patients planned for a surgical intervention, imaging is also important to select candidates for mitral valve (MV) repair over replacement and to predict surgical success...

OBJECTIVES: The aim of this study was to assess feasibility and clinical effectiveness of the MitraClip device in octogenarians suffering from severe mitral valve regurgitation due to chordae rupture. BACKGROUND: The MitraClip procedure is a suitable technique in high-risk surgical patients to achieve safe and effective percutaneous repair of mitral valve regurgitation. Octogenarians show cumulative risk and social aspects hindering mitral valve surgery. No data exists regarding the use of the MitraClip device in high-risk octogenarians suffering from mitral valve chordae rupture...

A previously healthy 61-year-old man presented to the emergency department with chest pain and dyspnoea for 6 hours. Examination revealed distress with an apical pansystolic murmur. Initial electrocardiogram showed sinus tachycardia and ST elevation in leads II, III, and aVF compatible with an inferior ST-elevation myocardial infarction. Point-of-care echocardiography in the emergency department showed a flail anterior mitral leaflet and severe mitral regurgitation, leading to a provisional diagnosis of papillary muscle rupture...

BACKGROUND: Parachute tricuspid valve is a rare congenital malformations explained in the literature. In most cases, this malformation coexists with other congenital defects. The importance of this condition depends on its functional consequences. CASE REPORT: First case was a 52-year-old female patient presented with palpitation. She had a history of paroxysmal supraventricular tachycardia. Transthoracic echocardiography revealed large secundum type atrial septal defect and all the tricuspid valve leaflets appeared to be connected to a single calcified papillary muscle in right ventricle suggestive of parachute tricuspid valve...
