Coronary Artery Tortuosity and Spontaneous Coronary Artery Dissection: Association With Echocardiography and Global Longitudinal Strain, Fibromuscular Dysplasia, and Outcomes.

ABSTRACT:

Background

The etiology and significance of coronary artery tortuosity (TCA) among patients with spontaneous coronary artery dissection (SCAD) are unknown. The aim of this prospective imaging cohort study was to report echocardiographic findings and evaluate whether TCA correlates with cardiac anatomy and function among patients with SCAD. Comorbidities including fibromuscular dysplasia (FMD) and outcomes were also assessed.

Methods

TCA was determined on coronary angiography performed during the diagnosis of SCAD, and cardiac structure and function were evaluated using prospective comprehensive echocardiography.

Results

Among 116 patients with SCAD, the mean age at echocardiography was 50.8 ± 8.8 years, a median of 10.9 months after SCAD. Sixty-two patients (53.4%) ha
