INTRODUCTION Right ventricular (RV) remodelling may be an important determinant of clinical outcome in patients undergoing mitral valve surgery for mitral regurgitation. In the present study we hypothesised that, compared to valve replacement, mitral valve repair for degenerative mitral regurgitation may result in better RV remodelling, as assessed by real-time, three-dimensional echocardiograp...

Congenital anomalies of the mitral valve apparatus are rare. Of such cases, congenital mitral stenosis, atresia, accessory valvular tissue, and cleft mitral valve are more common. Descriptions of unileaflet mitral valves (either partial or complete leaflet agenesis/hypoplasia) are extremely rare and largely limited to a few case reports. We report herein a 45-year-old nulliparous woman presenti...

Previously unreported echocardiographic findings are described of two cases with anterior mitral valve leaflet fenestration associated with infective endocarditis. M-mode echocardiograms demonstrated a periodic interruption in the echo tracing of the mitral valve ring area. Long axis real time two dimensional echocardiograms showed an echo defect in the body portion of the anterior mitral valve...

AIMS Deep clefts are a cause of early failure of mitral valve repair, but it is not known whether clefts represent normal morphology, or whether they occur more frequently in mitral valve prolapse (MVP). METHODS AND RESULTS Deep clefts were defined as indentations extending ≥ 50% of the depth of the mitral valve leaflet. Using trans-oesophageal echo (TOE), 3D zoom images were acquired of the ...

A 37-year-old male with acute complicated methicillin-sensitive Staphylococcus aureus mitral valve endocarditis underwent urgent valve replacement with a bileaflet prosthesis. The postoperative course was complicated with fever and heart failure. Echocardiography showed a large subannular false aneurysm of the left ventricle. Three weeks later resection and closure of the defect with a patch ma...

Real-time, phased-array, two-dimensional echocardiographic studies identified ruptured chordae tendineae in five patients: four patients had a flail mitral valve and one had flail mitral and tricuspid valves. The characteristic abnormality was a rapid systolic motion of the involved leaflet beyond the line of valve closure into the atrium. The maximal abnormal systolic motion was greatest at th...

OBJECTIVES This study sought to assess the use of real-time (RT) 3-dimensional (3D) transthoracic and transesophageal echocardiography (TEE) in the evaluation of post-operative mitral valve dehiscence. BACKGROUND Mitral valve replacement or repair may be complicated by post-operative dehiscence of the valve or annuloplasty ring resulting in clinically significant mitral regurgitation or hemol...

BACKGROUND Ischemic mitral regurgitation often complicates severe ischemic heart disease and adversely affects the prognosis in these patients. There is wide variation in the clinical spectrum of ischemic mitral regurgitation due to varying location and chronicity of ischemia and anomalies in annular and ventricular remodeling. As a result, there is lack of consensus in treating these patients....

Results of two-dimensional echocardiographic examinations were compared with angiographic, hemodynamic and surgical results in 44 patients with bioprosthetic valves in mitral and aortic positions who were undergoing elective or urgent reinvestigation 24 to 87 months (mean 34) after implantation. In these patients, there were 18 homograft aortic valves in the aortic position, 9 stent-mounted hom...
