Ten symptomatic dogs naturally infected by Leishmania infantum were examined by means of doppler echocardiography in order to identify the presence of pulmonary hypertension (HP). The presence of 2-dimensional features of PH and the presence of tricuspid and/or pulmonic valve regurgitation for pulmonary artery pressure quantification were investigated and standard echo-doppler variables (AT, AT/ET, Tei) were calculated. None of the examined dogs showed 2-dimensional features of PH. In only one dog, having also mitral endocardiosis, HP was diagnosed by tricuspid jet velocity. Echo-doppler variables resulted not indicative of HP in all dogs except one having a Tei index value predictive of HP, but normal AT and AT/ET. Our preliminary data do not support the presence of HP in canine leishmaniasis, anyway study population need to be enlarged to give conclusions.

Abstract
Ten symptomatic dogs naturally infected by Leishmania infantum were examined by means of doppler echocardiography in order to identify the presence of pulmonary hypertension (HP). The presence of 2-dimensional features of PH and the presence of tricuspid and/or pulmonic valve regurgitation for pulmonary artery pressure quantification were investigated and standard echo-doppler variables (AT, AT/ET, Tei) were calculated. None of the examined dogs showed 2-dimensional features of PH. In only one dog, having also mitral endocardiosis, HP was diagnosed by tricuspid jet velocity. Echo-doppler variables resulted not indicative of HP in all dogs except one having a Tei index value predictive of HP, but normal AT and AT/ET. Our preliminary data do not support the presence of HP in canine leishmaniasis, anyway study population need to be enlarged to give conclusions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
