Subclinical ventricular dysfunction by Speckle Tracking in adult patients with coarctation of the aorta. / Disfunción ventricular subclínica por Speckle Tracking en pacientes adultos con coartación de aorta.

Objective: The aim of this study was to investigate the presence of early left ventricular (LV) systolic dysfunction in adult patients with aortic coarctation (AoCo) and systemic arterial hypertension (SAH) compared to systemic hypertensive patients without coarctation and healthy controls by speckle tracking. Methods: Sixty-one subjects were studied, who attended consecutively to external consultation. All were submitted to clinical history, resting electrocardiogram, conventional echocardiogram and with Speckle Tracking. Results: 15 patients with AoCo and SAH were in functional class NYHA I, and five in functional class NYHA II. A significant inverse correlation was observed between the global longitudinal deformation and the left ventricular mass index in the AoCo and SAH group and in the hypertensive patients (r = 0.53, p = 0.02; r = 0.52, p < 0.0001, respectively). Conclusions: In patients with AoCo and SAH, global longitudinal deformation and left ventricular mass index are significantly related to subclinical LV dysfunction. These parameters are important and should be taken into account to regulate timely therapeutic behavior.
