Severe aortic insufficiency may accelerate mitral valve closure. We noted this echocardiographic finding in several patients with the acute onset of severe aortic insufficiency. Accordingly, we examined our total echocardiographic series retrospectively for early closure of the mitral valve (ECMV) in the setting of aortic insufficiency and found it in 11 of 53 patients with confirmed aortic ins...
OBJECTIVE This study investigated the use of a new concept of mitral valve reconstruction using a novel device to stent the posterior mitral leaflet in combination with semicircular annuloplasty. Modern mitral valve repair is an accepted modality and a routine procedure for treatment of degenerative mitral valve insufficiency. One of the most common mechanisms of mitral valve insufficiency is l...
In recent years mitral valve repair has gained increasing acceptance as the preferred treatment for mitral insufficiency. Mitral valve repair has many advantages. The surgical risk is lower than prosthetic valve replacement. Improved preservation of left ventricular function due to maintenance of the papillary muscle - mitral annular continuity - has been demonstrated. Thromboembolism is rare a...
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...
evidence of reduced venous return and alternating end-diastolic fiber length as causative factors. To the Editor: Attie et al.' reported their experience with valve replacement in children with mitral insufficiency. They divided their patients in three groups, depending on the type of prosthesis: mechanical valves, porcine xenografts and dura mater valves. Follow up times were 6.3, 3.3 and 1.9 ...
BACKGROUND Concomitant mitral regurgitation (MR) is frequently seen in patients undergoing aortic valve replacement (AVR) for aortic stenosis. This study was undertaken to characterize the magnitude of MR in these patients and identify factors associated with significant postoperative change. METHODS Between 2002 and 2006, 391 patients with stenotic AV disease but no structural mitral valve d...
Value of transesophageal echocardiography (TEE) guidance in minimally invasive mitral valve surgery.
The role of intraoperative transesophageal echocardiography (TEE) has increased tremendously since its first use in 1979. Today intraoperative TEE is a class I indication for surgical mitral valve reconstruction for evaluation of mitral valve pathology, graduation of mitral regurgitation and detection of potential risk factors as well as post-repair assessment. Real-time three-dimensional TEE o...
Diastolic murmurs associated with the Starr-Edwards mitral prosthesis have not been described previously. In this report, five patients with mitral prostheses are described in whom apical mid-diastolic and presystolic murmurs resulted from two different causes. Three patients had clots obstructing the prosthetic orifice. The other two had normally functioning protheses and moderately severe aor...
The electrocardiograms in 32 patients with mitral valve disease have been compared with the pulmonary resistances, the pulmonary artery pressures, and the size of the mitral valve orifice. In patients with pure stenosis if the electrocardiogram showed the pattern of right ventricular hyper-trophy the total pulmonary resistance was usually 1000 dynes seconds cm.-5 or greater. If mitral insuffici...
Methods This data is part of multi-center, nonrandomized, prospective Transapical Artificial Chordae Tendinae [TACT] trial. 13 patients with severe mitral regurgitation caused by isolated posterior mitral valve leaflet prolapse, were included in the study. The operation was done through left anterolateral thoracotomy on a beating heart. With TEE guidance, the NeoChord DS1000 was introduced into...
