Resumo: The myxomatous mitral valve degeneration is the main cardiac disease in dogs which can lead to congestive heart failure (CHF), with low survival. This illness presents a chronic course, and it affects aging dogs mainly. The clinical treatment is palliative, aiming at only the improvement in the clinical signs caused by CHF. The only way to interrupt its progression is improving the valvar function, by surgical repair or valvar replacement. In this study the technique of mitral valvar annuloplasty by external plication for reduction of the mitral annulus was evaluated by both anatomical and clinical studies. For the anatomical study six corpses of dogs that had died due to causes unrelated to the cardiovascular system were included, and four dogs with myxomatous mitral valve degeneration were used for the clinical study. The surgical technique consists of a buttressed double row running suture in the left ventricular free wall, ventral and parallel to the atrioventricular groove. In the anatomical study, there was a significant reduction in the lateral and septo-parietal diameter of the mitral annulus, 12.35% and 23.45% respectively. In the clinical study, two dogs presented mitral regurgitation jets reduction, from severe to mild-to-moderate jets, evidenced by the echodopplercardiography. One of them improved clinically and the other died 48h after surgery due to acute renal failure, and the remained two dogs died during the procedure due to hemorrhage caused for the plication. In this way, the studied technique revealed efficient in mitral regurgitation reduction, however it seems to be more indicated in dogs with CHF degree II than in dogs with CHF degree III.

Esta doença apresenta curso crônico e acomete, principalmente, animais idosos. O tratamento clínico visa à melhora dos sinais clínicos provocados pela IC, sendo, portanto, paliativo. A única forma de interromper a progressão da doença é a melhora da função valvar, por meio de reparo cirúrgico ou substituição valvar. Neste trabalho foi utilizada a técnica de anuloplastia valvar mitral por plicatura externa, com o intuito de se avaliar a redução do diâmetro do anel mitral, por meio de estudos anatômico e clínico. No estudo anatômico utilizaram-se seis cadáveres de cães que foram a óbito devido a causas não relacionadas ao sistema cardiovascular e no estudo clínico utilizaram-se quatro cães acometidos pela degeneração mixomatosa da valva mitral. A técnica de anuloplastia valvar mitral por plicatura externa consistiu na realização de sutura em padrão de Lembert, em dois planos, na parede livre do ventrículo esquerdo, ventral e paralelamente ao sulco átrio-ventricular. No estudo anatômico, houve redução significativa nos diâmetros látero-lateral e septo-parietal do anel mitral, de 12,35% e 23,45%, respectivamente. No estudo clínico, dois cães apresentaram redução no jato de regurgitação mitral, de grau severo para leve a moderado, constatado pelo ecodopplercardiograma, sendo que um deles melhorou clinicamente e o outro foi a óbito 48 horas após o procedimento devido à insuficiência renal. Os demais foram a óbito durante o procedimento devido à hemorragia causada pela plicatura. Deste modo, a técnica estudada mostrou-se eficaz na redução da regurgitação mitral, porém parece ser mais indicada em cães com IC de grau II do que nos cães com IC grau III.Universidade de FrancaBrasilPós-GraduaçãoPrograma de Mestrado em Cirurgia e Anestesiologia VeterináriaUNIFRANAndrade, James Newton Bizetto Meira de8565405078972705http://lattes.cnpq.br/8565405078972705Guimarães, Gregório Corrêa2752876115859495http://lattes.cnpq.br/2752876115859495Nishimori, Celina Tie Duque9867050564803302http://lattes.cnpq.br/9867050564803302Olivaes, Cláudio Galvão de2020-05-21T19:53:02Z2020-05-21T19:53:02Z2010-02-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfOLIVAES, Cláudio Galvão de.
