Beating heart partial ventriculectomy in dogs

After valve endocardiosis, dilated cardiomyopathy is the most diagnosed cardiac affection in dogs. Sometimes this disease is unresponsible to medical therapy, in this way surgery becomes necessary to its correction. Unfortunately, dogs do not support cardiopulmonary bypass because its tendency in microtrombus formation in the capillary vessels of the lung circulation. Due to this condition, another surgical alternatives were developed, in order to correct the increase in ventricle size, as the ventricle plication or partial ventriculectomy with the inflow occlusion. However, this kind of technique has its complications, as well the ventricle plication. In plication, a part of necrotic heart tissue still remains, and if the necrosis does not happen, that portion of myocardium keeps its oxygen consumption, leading to heart failure. The partial ventriculectomy with the inflow occlusion is time dependent. For its execution it means that the surgeon gets only four minutes to perform the resection of the dilated ventricle and then suture the remaining defect after the inflow occlusion. The aim of this study is to develop a new technique of heart size reduction, called by the authors Beating Heart Partial Ventriculectomy

Ventriculectomia Parcial com Coração em Movimento em cães

A cardiomiopatia dilatada, depois da endocardiose valvar, é a afecção cardíaca mais diagnosticada em cães. Por vezes esta doença é irresponsível ao tratamento médico. Nestes casos a cirurgia torna-se necessária na correção da dilatação. Infelizmente, os cães não toleram bem a circulação extracorpórea, pois têm predisposição à formação de microtrombos na circulação pulmonar. Devido a esta condição, outras alternativas cirúrgicas foram desenvolvidas, de forma a corrigir o aumento ventricular, como a plicatura ventricular ou a ventriculectomia parcial com oclusão do afluxo. Contudo, esta técnica possui complicações, assim como a plicatura ventricular. Na plicatura ventricular, ocorre a permanência de uma porção necrótica de miocárdio e, quando isto não acontece, o tecido mantém o seu consumo de oxigênio, levando à falha cardíaca. A ventriculectomia com oclusão do afluxo sanguíneo é tempo-dependente. Para a sua execução o cirurgião precisa realizar a ressecção do ventrículo e a sutura do defeito remanescente em apenas quatro minutos. O objetivo deste estudo é desenvolver uma nova técnica de redução ventricular, denominada pelos autores como Ventriculectomia Parcial com Coração em Movimento.After valve endocardiosis, dilated cardiomyopathy is the most diagnosed cardiac affection in dogs.
