ECHOCARDIOGRAPHIC ASSESSMENT OF 537 DOGS WITH MITRAL VALVE PROLAPSE AND LEAFLET INVOLVEMENT
2009
In this work we investigated which mitral valve leaflet was most often involved in mitral valve prolapse with degenerative mitral valve disease and whether there was an association with breed, age, gender, or weight. Five hundred and thirty-seven dogs with mitral valve prolapse-degenerative mitral valve disease were assessed; the cross-breed dog was the most represented breed (248 dogs, 46.2%). Mitral valve prolapse was more common in male dogs, and the average age was 11.3 +/- 2.8 years. Prolapse of the anterior leaflet was present in 48.4% of dogs, prolapse of the the posterior leaflet in 7.1%, and bileaflet prolapse was present in 44.5%; this distribution is different than that typically…
Mitral Valve Repair Without Using Rings or Slings
1989
Reconstructive surgery of the mitral valve is still deemed superior to prosthetic replacement because of the lower operative risk as well as the fewer thromboembolic complications [1, 2]. Whereas closed or open commissurotomy of a stenosed mitral valve has been routine in the past and present [3], reconstructive measures for incompetent valves have been among those least often performed. The use of rigid or semi-flexible annular rings [4–9] has significantly contributed to progress in this field. However, these are not suitable for repair of all valvular lesions and undoubtedly have at least some of the negative features of prosthetic substitutes. We have therefore started a program of mitr…
Congenital mitral regurgitation caused by a perforation in the anterior leaflet: Perioperative evaluation by color-coded Doppler echocardiography
1990
Color-coded two-dimensional (2D) echocardiography confirmed the presence of severe congenital mitral regurgitation in an 8-month-old infant. Intraoperative inspection revealed an isolated perforation in the anterior leaflet.
