| dc.description.abstract | Echocardiography has become a very important diagnostic exam in veterinary cardiology, being consider as the exam of choice in many of the small animals cardiopathies. Recently, new echocardiographic techniques have been studied with the intent of improving diagnostic accuracy, introducing new parameters on the routine echocardiographic exam. These techniques, namely Tissue Doppler imaging and Specke Tracking, are already well established in human medicine cardiology and many studies have proven their value and effectiveness. During the last decade, these techniques have also been studied in veterinary medicine. Tissue Doppler imaging and Bi-dimensional Speckle Tracking deliver new parameters in evaluating the myocardium performance, as the evaluation of the deformation indices (Strain and Strain Rate), ventricular torsion and synchrony. In this review, relevance will be given to these parameters and how they affect changes on the left ventricle. This will be achieved by gathering studies recently made in various cardiopathies, as well as the normal values for myocardial deformation in healthy animals. This review will also focus on these techniquesā ability to detect early changes, allowing the clinicians to use proper and timely therapeutic decisions. This is a very important factor, since it could have impact on definitive diagnosis and future prognosis of several diseases. | pt_PT |
| dc.description.abstract | Em Medicina VeterinĆ”ria, a ecocardiografia tornou-se um exame complementar de extrema importĆ¢ncia no diagnĆ³stico definitivo de vĆ”rias cardiopatias, sendo considerada como o mĆ©todo diagnĆ³stico de eleiĆ§Ć£o. Recentemente, novas modalidades ecocardiogrĆ”ficas tĆŖm sido estudadas com o intuito de melhorar a capacidade de diagnĆ³stico e introduzir novos parĆ¢metros no exame ecocardiogrĆ”fico de rotina. Em Medicina Humana, as referidas tĆ©nicas de ecocardiografia mais avanƧadas, como o Doppler tecidular e o Speckle Tracking sĆ£o jĆ” utilizadas na rotina da prĆ”tica clĆnica, existindo diversos estudos que comprovam o seu valor e eficĆ”cia. Durante a Ćŗltima dĆ©cada estas tĆ©nicas tĆŖm vindo tambĆ©m a ser estudadas em Medicina VeterinĆ”ria, sendo o Speckle tracking bi-dimensional considerado o mais recente. Tanto o Doppler Tecidular como o Speckle Tracking fornecem novos parĆ¢metros de avaliaĆ§Ć£o da performance do miocĆ”rdio, como a avaliaĆ§Ć£o dos parĆ¢metros de deformaĆ§Ć£o (Strain e Strain Rate), torsĆ£o ventricular e sincronia mecĆ¢nica do miocĆ”rdio. Nesta revisĆ£o serĆ” dada relevĆ¢ncia Ć s alteraƧƵes destes parĆ¢metros no estudo do ventrĆculo esquerdo. Desta forma, esta revisĆ£o tem como objectivo reunir os estudos feitos recentemente em diversas cardiopatias, assim como em animais saudĆ”veis, podendo estes servir como referĆŖncia na validaĆ§Ć£o futura dos parĆ¢metros de deformaĆ§Ć£o. SerĆ” dado maior relevo Ć capacidade destas tĆ©cnicas detectarem alteraƧƵes precocemente, possibilitanto ao clĆnico uma conduta terapĆŖutica adequada, antes dos parĆ¢metros obtidos na ecocardiografia convencional se apresentarem alterados. Este factor Ć© de extrema importĆ¢ncia para o desenvolvimento da abordagem terapĆŖutica quer no prognĆ³stico quer no diagnĆ³stico definitivo das cardiopatias em Medicina VeterinĆ”ria. | pt_PT |
