The study carried out on 35 patients (10 males and 25 females, 16 - 66 years old) who had diagnosis of mitral stenosis with insufficiency at Cardiovascular Hospital and Viet Duc Hospital from 8/1999 to 3/2004. Results: diagnosis of mitral stenosis with insufficiency level and evaluation condition of valve and under valve organizations injuries as pustule injury, pustule position, quantity of pustules through transeophageal echocardiography were more accurate than transthoracic echocardiography. There were 4 patients (11.4%) operated to repair mitral valve, 6 patients (17.1%) replaced mitral valve and 18 patients (51.4%) had bacterial endocarditis

Although several reports have showed the application of 3-dimensional (3D) echocardiography, it is hard to find a report regarding the intraoperative use of real time 3D transesophageal echocardiography (TEE) in mitral valve repair surgery. In the present case, real time 3D TEE the one from the one TEE probe position as well as their rotated and cropped images showed detailed spatial images enough for immediate assessment of the mitral valve deformity and the characteristics of mitral regurgitation flow. Under cardiopulmonary bypass (CPB) employing moderate hypothermia, the prolapsed mital leaflet was excised, the ruptured cord was repaired and an annuloplasty ring was inserted to reinforce the mitral valve and to close up the defect. The 2D and 3D TEE images after CPB showed effective repair providing complete closure of the mitral leaflets and absence of residual regurgitation flow. Considering that the conventional 2D TEE requires examiner's ability to gather the various 2D TEE images and experience essential for intergrating the 2D images for full understanding of spatial structure of valvular deformity and dysfunction, 3D TEE's ability for making a comprehensive spatial image from a limited number of 2D images seems to have an additional clinical efficacy in intraoperative TEE monitoring for cardiac value surgery.

A valvular perforation is a well-known, and common, complication of infective endocarditis that may adversely affect the clinical outcome. However, a 'windsock' deformity of the mitral valve, as a delayed presentation of infective endocarditis, affecting the mitral valve alone, is very rare. A 42-year-old man, who underwent a mitral valvuloplasty and annuloplasty six years previously, suddenly developed pulmonary edema. He had also had a previous history of infective endocarditis, dating back three years. A transthoracic echocardiogram revealed a 'windsock' deformity of the anterior mitral leaflet (AML), resulting in an acute severe mitral regurgitation. During the operation, the AML was found to have been damaged by the previous endocarditis, resulting in an aneurysmal change of the central scallop, and a rupture of the roof. A mitral valve replacement was successfully performed, and the patient recovered uneventfully. Here, we report a rare case of a 'windsock' deformity of the mitral valve, with two perforations as a delayed complication of a healed infective endocarditis.

Double-orifice mitral valve is a relatively rare congenital abnormality, usually discovered at autopsy or surgery. In most cases, the double-orifice mitral valve causes no hemodynamic effects, sometimes it is regurgitant, and rarely is stenotic. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is often associated with other congenital anomalies and this echocardiographic findings may be confused with other cardiac abnormalities. The authors report a case of isolated congenital double-orifice mitral valve in a 42-year-old woman. Data from the literature are reviewed and the echocardiographic images of the malformation are described.

Since the Inoue balloon was first introduced for percutaneous mitral valvuloplasty (PMV) in 1984, this procedure has come into widespread use because of its effectiveness, simplicity, and reduced exposure to X-ray radiation. It's the procedure's complications include cardiac tamponade, atrial septal defect, thromboembolism, ventricular perforation, mitral regurgitation, and rarely balloon rupture. We report a case of Inoue balloon deformity during PMV in 62-year old woman with rheumatic mitral stenosis. Echocardiography revealed severe rheumatic mitral stenosis with a valvular area of 0.95 cm2 (by pressure half-time method), and an Echo score of 10 points. The PMV with Inoue balloon 28 mm was performed. We inflated the balloon to 28 mm in diameter first, and to 29 mm second. A bulging deformity with asymmetrical overinflation of one side of both proximal and distal balloon was recognized. A bulging deformity at the proximal part of Inoue balloon after second inflation. Balloon was not ruptured. Following completion of the procedure, the mitral valve area increased to 1.8 cm2. Moderate mitral regurgitation (grade II) was newly developed. This may be the first case of asymmetrical one side inflation and focal bulging deformity reported in Korea.

Double-orifice mitral valve is a rare congenital anomaly. Most cases of double-orifice mitral valve are hemodynamically normal and remain symptomless, so that it is usually discovered incidentally in autopsy or during surgical correction of a cardiovascular abnormality. Recently, however, it is increasingly recognized as such, since the echocardiography has gained wide acceptance as a non-invasive diagnostic tool by the M-mode, two-dimensional and color Doppler echocardiogram. Two separate mitral valve apparatuses can be used on the M-mode echocardiogram. In the two-dimensional echocardiography, the parasternal and subcostal short-axis views can show two separate glass-like orifices in the left ventricle, and the parasternal long-axis view as well as the apical four-chamber view can show the anomaly. And the color Doppler echocardiogram can visualize two mosaic-pattern flows between the left atrium and ventricle. We present herewith two cases of double-orifice mitral valve, as diagnosed by means of echocardiography. The first case was an isolated one with mitral stenosis, showing two parachute mitral valves. The second was associated with perimembranous ventricular septal defect, and showed the accessory mitral valve directly attached to the ventricular septum, with the chordae crossing the ventricular outflow tract.

Robotically assisted mitral valve repair has proven its efficacy during the last decade. The most suitable approach for patients with difficult anatomies, such as morbid obesity, sternal deformities, cardiac rotation, or vascular anomalies, represents a current challenge in cardiac surgery. Herein, we present the case of a 71-year-old patient affected by severe degenerative mitral valve regurgitation with pectus excavatum and a right aortic arch with an anomalous course of the left subclavian artery who was successfully treated using a Da Vinci–assisted approach.

We report here on a case of double-orifice mitral valve with mitral regurgitation in a 75-year-old female who had complaints of mild dyspnea. Transthoracic and transesophageal echocardiography showed two orifices that were supplied by their own chordae from a different papillary muscle. Color Doppler echocardiography revealed moderate to severe mitral regurgitation due to the flail posterior leaflet of the anterolateral orifice. Except for the persistent left superior vena cava, no other congenital anomaly was demonstrated. The patient became asymptomatic with the administration of angiotensin-converting enzyme inhibitor and diuretics, and she has been scheduled for long term follow-up.

BACKGROUND: Before the development of an ideal artificial valve, repairing of native valves was considered the best choice and clinicians have been reported that valvuloplasty was much better than valve replacement, when possible with the respect to clinical outcomes. This study was conducted under the hypothesis that in some cases, the surgical and clinical outcomes could be better in patients with valve replacement and it may be influenced by left ventricular function. MATERIAL AND METHOD: This study included 40 patients who received pure mitral valve regurgitation. We divided the patients into three groups(Group I: classical valve replacement in 12 patients, Group II: preserving posterior leaflet in 18 patients, Group III: valvuloplasty in 10 patients) and compared the patient`s clinical findings, echocardiographical indexes obtained at admission and 4 weeks after operation. RESULT: After operation, Group II and III showed the better clinical condition changes than Group I but there was no statistical significance. According to NYHA classification, favorable results were achieved but there are no statistical significances in these three patient groups. The left ventricular function was worsened in Group I and in the Groups II and III, the left ventricular function showed no changes postoperatively. In Groups II and III, there were improvements in the postoperative clinical findings but the left ventricular ejection fraction revealed no statistical differences in these two groups. CONCLUSION: Due to different left ventricular functions, repair is considered a better method for the mitral regurgitation. If there the deformity is impossible to repair, preserving a portion of the leaflet is the preferred surgical method.
