- Dark side of the heart: echocardiographic assessment of the right heart chambers and its clinical applicationsPublication . Neves, Tiago José Loureiro; Vieira, Maria João Nobre de Matos Pereira; Oliveira, João Manuel Pimenta FerreiraRight ventricular dysfunction is under-recognized in veterinary medicine, and has relied more on qualitative signs of right-sided congestive failure, rather than on quantitative cardiac indices (Visser, Scansen, Schober, & Bonagura, 2015b). Haddad, Doyle, Murphy, and Hunt (2008a), and more recently Lang, Badano, Mor-Avi, Afilalo, Armstrong, Ernande et al. (2015) published studies that highlight the prognostic value of right heart assessment, not only in right heart diseases but also for diseases affecting the left heart diseases. According to de Madron, Chetboul, and Bussadori (2015), there are several diseases that affect the canine right heart, such as arrhythmogenic right ventricular cardiomyopathy, dilated cardiomyopathy, pulmonary hypertension and congenital malformation of the pulmonic and tricuspid valves. It is therefore important to use echocardiographic parameters with high feasibility and repeatability and low intra- and interobserver variability that efficiently quantify right ventricular function. With the evolution in echocardiographic examination and technology, new parameters have been studied and reference values become increasingly accessible for the veterinarian cardiologist. The aim of this thesis was to review the state of knowledge on the clinical applicability of echocardiography to assess right ventricular function, emphasizing the methodology for image acquisition, evaluated parameters, advantages and limitations of each technique, their prognostic value and applicability to the different clinical scenarios.
