Left and Right Ventricular Strain Mechanics in Fetal Tachyarrhythmia.

ABSTRACT:

Introduction

Assessment of myocardial function in fetuses with supraventricular tachyarrhythmia is challenging. Speckle-tracking echocardiography (STE) is a newer sensitive method to assess ventricular systolic function. We sought to assess left (LV) and right (RV) ventricular myocardial strain mechanics in fetuses with tachyarrhythmia and hypothesized that strain mechanics are impaired in this patient population even after conversion to sinus rhythm.

Methods

This was a single-center retrospective review. LV and RV strain parameters were assessed using STE in tachyarrhythmia and after conversion to sinus rhythm and, compared to gestational age (GA), matched control fetuses in sinus rhythm.

Results

Eighteen fetuses with tachyarrhythmia and 18 controls were analyzed at
