1/275. Penetrating trauma to the tricuspid valve and ventricular septum: delayed repair.Penetrating cardiac trauma can result in a wide range of injuries to intracardiac structures. Missile injury, in particular, can cause damage in more than one cardiac chamber that may be difficult to identify at initial emergent operation. We report a case of late repair of traumatic ventricular septal defect and tricuspid valve perforation from gunshot wound. This case illustrates the importance of thorough examination of intracardiac anatomy during emergent and delayed repair for penetrating cardiac trauma.- - - - - - - - - - ranking = 1keywords = valve (Clic here for more details about this article) |
2/275. myocardial infarction caused by compression of anomalous circumflex coronary artery after mitral valve replacement.We report a case of myocardial infarction after mitral valve replacement occurring in a patient with the left cyrcumflex coronary artery arising from the right one. The patient underwent mitral valve replacement with a size 27 Carbomedics prosthesis and a tricuspidal annuloplasty was performed according to the De Vega technique. Patient died on the 20th postoperative day.- - - - - - - - - - ranking = 1.2keywords = valve (Clic here for more details about this article) |
3/275. Possibility of focal activation around the left upper pulmonary vein during chronic atrial fibrillation with mitral valve disease.Focal regular activations were sometimes observed during chronic atrial fibrillation (AF) associated with mitral valve disease. We present a 58 year-old male diagnosed with mitral valvular stenosis and regurgitation with chronic atrial fibrillation. Intraoperative mapping of both atria was performed during mitral valvular surgery. Regular and repetitive activations around the left superior pulmonary vein were observed, in contrast to irregular and chaotic activations of the right atrium. This regular activation was supposed to be the focus of chronic AF. Surgical ablation of the posterior left atrium was successfully performed and eliminated the chronic AF, concomitant with mitral valve replacement.- - - - - - - - - - ranking = 1.2keywords = valve (Clic here for more details about this article) |
4/275. Asymmetrically short tendinous cords causing congenital tricuspid regurgitation: improved understanding of tricuspid valvar dysplasia in the era of color flow echocardiography.BACKGROUND: Tricuspid regurgitation as a manifestation of an isolated congenital anomaly of the tricuspid valve is rare. Cross-sectional and color Doppler echocardiography allow improved evaluation of tricuspid valvar function. As a result, the heterogeneous category of congenital tricuspid valvar dysplasia may be better understood from a functional point of view. We are reporting a distinct entity in which tricuspid valvar regurgitation results from failure of coaptation due to short tendinous cords tethering the septal leaflet. patients AND RESULTS: Three children with significant primary tricuspid regurgitation were evaluated, treated, and followed. On echocardiographic evaluation, a central regurgitant jet of moderate or severe degree was directed toward the atrial septum through poorly coapting tricuspid valvar leaflets, which did not approximate due to tethering of the septal leaflet by abnormally short cords. In one patient, the tricuspid valve was otherwise normal; in the other two the leaflets and cords were also thickened. Two patients underwent surgery at 9 and 11 years of age. The cords tethering the septal leaflet were augmented by interposing appropriate lengths of expanded polytetrafluoroethylene suture and performing commissural annuloplasty. Both patients are asymptomatic 33 and 42 months postoperatively, with mild residual tricuspid regurgitation that has not changed since surgery. The other patient, an 8 month-old infant, has not yet undergone surgery. CONCLUSIONS: Asymmetric tendinous cords of the tricuspid valve causing tethering of the septal leaflet is a distinct cause of tricuspid regurgitation that can be recognized with echocardiography. Although rare, the importance of recognizing this lesion lies in its being readily amenable to surgical repair.- - - - - - - - - - ranking = 0.6keywords = valve (Clic here for more details about this article) |
5/275. Partial rupture of the tricuspid valve after extraction of permanent pacemaker leads: detection by transesophageal echocardiography.Traumatic lesions of the tricuspid valve complicating pacemaker lead extractions appear to be rare. We report two cases of partial rupture of the tricuspid valve, following apparently uneventful extraction of permanent ventricular leads, resulting in severe regurgitation and, in one case, chronic heart failure. TEE was useful to identify the traumatic mechanism of tricuspid regurgitation (TR) and the extent of valvular lesions in these patients. Such etiology should be suspected, and TEE performed, in patients developing TR or heart failure late after lead extraction.- - - - - - - - - - ranking = 1.2keywords = valve (Clic here for more details about this article) |
6/275. Combined mitral and tricuspid valve repair in acute infective endocarditis.Combined repair of the mitral and tricuspid valves involved with acute infective endocarditis was carried out in a 38-year-old drug addict. mitral valve repair included vegetectomy, closure of posterior leaflet perforation, and posterior annuloplasty with a patch and a strip of glutaraldehyde-tanned autologous pericardium, respectively, while the tricuspid valve was reconstructed with the use of artificial chordae and valve bicuspidalization. At five months follow up the patient is asymptomatic, with echocardiographic evidence of only trivial mitral and tricuspid incompetence, and no signs of recurrent infection. This case report supports the use of valve reconstruction as a valuable option in patients in whom there is simultaneous involvement of the mitral and tricuspid valves with infective endocarditis.- - - - - - - - - - ranking = 2keywords = valve (Clic here for more details about this article) |
7/275. Isolated tricuspid valve regurgitation resulting from severe annular dilatation: case report.A rare case of isolated tricuspid regurgitation (TR) in a 65-year-old man is presented. echocardiography revealed enlargement of the right atrium, dilatation of the tricuspid valve annulus without thickening or prolapse of the leaflets, and an intact atrial septum. No downward displacement of the tricuspid septal leaflet was observed by echocardiography. Mild mitral regurgitation and severe TR were detected on color flow Doppler studies. cardiac catheterization indicated elevated right atrial pressure, with a pronounced V-wave. No left-to-right shunt was detected at the right atrium. At surgery, severe annular dilatation of the tricuspid valve (without organically diseased or deformed tricuspid leaflets) was observed, and tricuspid annuloplasty with a prosthetic ring performed. Postoperative echocardiography and right ventriculography showed trivial TR.- - - - - - - - - - ranking = 1.2keywords = valve (Clic here for more details about this article) |
8/275. Video-assisted tricuspid valve surgery: a new surgical option in endocarditis on pacemaker.A patient presenting with a pacemaker lead infection and tricuspid regurgitation underwent a minimally invasive video-assisted tricuspid valve replacement. The valve was approached through a right anterior mini thoracotomy. Under thoracoscopic vision and peripheral cardiopulmonary bypass, a catheter was placed on the ascending aorta for antegrade cardioplegia delivery. A transthoracic aortic cross-clamp was introduced through the third right intercostal space. tricuspid valve replacement added to the pacemaker leads ablation was exclusively performed under thoracoscopic vision, providing an excellent video-image in this reduced operative field. After 22 months of follow up, the patient is asymptomatic, the echocardiography showing a normally functioning valve.- - - - - - - - - - ranking = 1.6keywords = valve (Clic here for more details about this article) |
9/275. Isolated tricuspid regurgitation due to atypical morphology of anterior-posterior leaflets in an adult: a case report and review of the literature.A 73-year-old woman with congenital isolated organic tricuspid regurgitation was reported. She had neither the history of chest trauma nor rheumatic fever nor the evidence of infective endocarditis. The patient was successfully treated with a bioprosthetic valve replacement in tricuspid position. Operative findings revealed hypoplastic anterior leaflet and relatively large posterior leaflet. Structural anomaly of the valve, coaptation disorder due to the thickened valve leaflets, as well as enlarged valve ring and the occurrence of atrial fibrillation was thought to be the causes of massive regurgitation.- - - - - - - - - - ranking = 0.8keywords = valve (Clic here for more details about this article) |
