Left atrial and ventricular impairment of asymptomatic pediatric myocarditis survivors: analysis by speckle tracking and exercise stress echocardiography.

ABSTRACT:

Background

The study of mid- and long-term myocardial function in myocarditis survivors was limited, which cannot fully reflect their clinical prognosis. The present study was carried out to prospectively evaluate the left atrial (LA) and ventricular (LV) function of pediatric myocarditis survivors by speckle tracking echocardiography (STE) combined with stress echocardiography and to uncover its potential risk factors regarding myocardial impairment during follow-up.

Methods

Fifteen consecutive asymptomatic pediatric myocarditis survivors and fifteen age- and sex-matched healthy controls were prospectively enrolled. LA and LV deformations at rest and after stress tests were evaluated by conventional echocardiography and STE. The cardiac function reserve reflected as the dif
