Introduction: Mitral stenosis is a condition characterized by the narrowing of mitral valve, which regulates blood flow between left atrium and ventricle heart. Objectives: The main objective study to find mid-term clinical echocardiographic outcomes percutaneous transvenous commissurotomy in patients with rheumatic stenosis. Material Methods: present was retrospective observational conducted a...

Aims: The purpose of this study was to determine whether there is any association between the optimal increase in mitral valve area and mitral transvalvular gradient decrement and pulmonary arterial pressure decrement after balloon mitral valvuloplasty (BMV) in patients with mitral stenosis. Methods: The study population consisted of 49 patients (47 women, 2 men; mean age = 43.7±13.35 years) wi...

BACKGROUND Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. METHODS We simulated AF with different severity grades of left-sided va...

The treatment of mitral valve disease remains dynamic; surgeons and patients must now choose between many different surgical options when addressing mitral regurgitation and mitral stenosis. Notably, advances in imaging and surgical instrumentation allow surgeons to perform less invasive mitral valve surgery that spares the sternum. With favorable long-term data now emerging, we compare the ben...

Mitral stenosis usually occurs many years after an episode of rheumatic fever and it has an indolent course until its later stages, when it acutely worsens. The rates of mitral stenosis keep declining; nonetheless, the need for advanced and sophisticated treatment modalities still remains. Our group has been applying a novel modified antegrade approach for treating mitral valve stenosis and, al...

Mitral stenosis due to rheumatic heart disease is not common in the United States but is common in the developing world because rheumatic fever is still occurring frequently. Symptoms usually gradually occur in the young adult (most commonly female). Atrial fibrillation is a common accompanying rhythm in patients with proven mitral stenosis. The main physiologic event is a pressure gradient bet...

A 12-year-old child with no previous medical history was referred with a 4-day history of cough, shortness of breath, and peripheral blood eosinophilia. Transthoracic echocardiography showed a soft tissue infiltrating the left ventricular free wall, the lateral mitral annulus, and the mitral valve leaflets. A soft tissue strand connecting the lateral left atrial wall and mitral leaflets across ...

OBJECTIVES We sought to compare the maternal and fetal outcomes of patients with severe mitral stenosis submitted to percutaneous balloon dilation versus open mitral valve commissurotomy (MVC) during pregnancy. BACKGROUND Heart failure in patients with mitral stenosis complicating pregnancy is a common problem in developing countries. Since 1984, percutaneous dilation of the mitral valve usin...

OBJECTIVE The purpose of this study was to evaluate the tenascin-C levels in severe rheumatic mitral stenosis before and after percutaneous mitral balloon valvuloplasty (PMBV). SUBJECTS AND METHODS Forty patients with severe mitral stenosis requiring PMBV and 20 age-matched healthy subjects were included in the study. The mitral valve areas, mitral gradients and systolic pulmonary artery pres...
