Echocardiographic Study of the Coronary Sinus in the Indeterminate Form of Chagas Disease

Abstract

Introduction: We investigated the occurrence of coronary sinus abnormalities in the indeterminate form of Chagas disease (CD). Methods: Differences between the maximum and minimum diameters of the coronary sinus (∆%) on echocardiography were evaluated in individuals with the indeterminate form of CD (n=14) and those without (n=16) CD. The association of the difference with abnormalities detected by echocardiography and myocardial scintigraphy was assessed. Results: The mean Δ% values did not differ significantly between the groups. There was no correlation of the measurements with echocardiographic and myocardial scintigraphy findings. Conclusions: The coronary sinus evaluation revealed no differences between the groups.

“…Considerado um método fácil e superior a ecocardiografia convencional na avaliação da função sistólica e diastólica, o Doppler tissular, especialmente no anel mitral demonstrou anormalidades precoces na contratilidade miocárdica, especialmente em pacientes com forma indeterminada. Apesar que não foram encontradas anormalidades no seio coronário e na contratilidade cardíaca de pacientes com a forma indeterminada (PEREIRA JUNIOR et al, 2014;LIMA et al, 2017;MACHADO et al, 2018).…”
