Valvular heart disease is a significant cause of morbidity and mortality. Rates increase with age and the prevalence will increase as the population ages. Several factors have led to an interest in expanding percutaneous valve repair and replacement techniques to more lesions in more patients. This review explores current percutaneous valve repair and replacement techniques in mitral stenosis, ...

Echocardiographic studies of the mitral valve were performed in 57 patients with pure or predominant mitral stenosis who subsequently underwent surgery (30 commissurotomy, 27 valve replacement). Mitral valve calcification was graded heavy (thick, conglomerate echoes), light (multiple, discrete linear echoes) or none (thin, single or duplicate signals). Valve mobility, measured as the excursion ...

In complex, data-based prediction problems, such as medical diagnosis, the Elman Neural Net (ENN) has been applied for the automated detection of various diseases, such as mitral valve stenosis. This paper discusses the design and implementation of an automated classification system for heart diseases, based on ultrasonic devices. M-mode class images are applied to classify the degree of stenos...

Various cases of accessory leaflets of mitral valve or tissue around the opening have been reported in the past. In some cases they were the main etiological factor for sub aortic stenosis or regurgitation. Here we report a rare finding of accessory posterolateral cusp of mitral valve with accessory papillary muscle in left ventricle of an adult male cadaver. Such variation has not been reporte...

INTRODUCTION Several studies have shown a wide variability among different methods to determine the valve area in patients with rheumatic mitral stenosis. Our aim was to evaluate if 3D-echo planimetry is more accurate than the Gorlin method to measure the valve area. METHODS Twenty-six patients with mitral stenosis underwent 2D and 3D-echo echocardiographic examinations and catheterization. V...

As part of a follow-up investigation in mitral annuloplasty by reflected ultrasound, 39 studies have been carried out in I5 patients who underwent mitral valve reconstructive operations. The rate of diastolic toward closure movemeiit from point E (EF speed) and total amplitude did not correlate with the final valve orifice dimension obtained at operation. Mitral stenosis and incompetence were s...

Intraprocedural imaging continues to evolve in parallel with advances in percutaneous mitral valve interventions. This didactic review uses several illustrations and rich intraprocedural videos to further describe and demonstrate the role of the most up-to-date echocardiographic and advanced imaging technologies in the patient selection and intraprocedural guidance of percutaneous mitral valve ...

The most common cardiac cause of massive hemoptysis is mitral stenosis. Mitral regurgitation is rarely complicated by massive hemoptysis. A 48-year-old man with no significant medical history was admitted to our hospital with hemoptysis and production of 500 mL of blood within 24 hours. A pan-systolic murmur was found on chest examination. A chest computed tomography showed airspace consolidati...

The surgical strategy in infants with mitral valve stenosis or atresia without diminutive ascending aorta remains to be established, including the potential for biventricular repair as a definitive operation. Our surgical experience of six infants with mitral valve stenosis (4 patients) or atresia (2 patients) without diminutive ascending aorta was evaluated based on three important factors: le...
