Mitral valve repair in dogs

Myxomatous Mitral Valve Disease in Dogs - an Update and Perspectives

“…In the case of prosthetic valves, matching the size of the valve and conquering thrombosis is essential for long-term prognosis (36). Recently, successful techniques for mitral valve repair with annuloplasty and chordal replacement have been utilized, which enables long-term survival for severe MMVD patients (37). Costs and availability are the major drawbacks of this option.…”

Mitral Valve Replacement with a Mechanical Valve for Severe Mitral Regurgitation in a Small Dog

“…In human [2,3] and veterinary medicine [13][14][15][16][17], MVP is currently preferred over MVR for providing good QOL. However, it is difficult to completely repair severely damaged valves with MVP in a terminal stage case.…”

Treatment of severe mitral regurgitation caused by lesions in both leaflets using multiple mitral valve plasty techniques in a small dog

“…Mitral valve plasty (MVP) is the preferred surgical treatment over mitral valve replacement (MVR) for MR in humans because of its positive effect on quality of life (Carpentier et al, 2010). Recently, there have been increased reports of using MVP to treat MR in dogs (Kanemoto et al, 1990(Kanemoto et al, , 2004Boggs et al, 1996;Griffiths et al, 2004;Uechi, 2012). However, there have been few reports of the application of MVP to treat severe MR involving the posterior leaflet (PL) in small dogs (Boggs et al, 1996;Uechi, 2012;Kanemoto et al, 2017), in whom MVR was previously indicated (Orton et al, 2005;Taguchi et al, 2014).…”

Herein, we describe a case of severe MR caused by multiple lesions in the PL in a mixed Chihuahua, who was treated with a combination of the following three MVP techniques: artificial chordal reconstruction (CR) for the anterior leaflet (AL) and the PL, semicircular suture annuloplasty (AP) for a dilated mitral annulus, and valvuloplasty (VP) using newly devised direct scallop sutures for the PL.…”
