Background: Left ventricular global longitudinal strain (LVGLS) has been shown to improve risk stratification in patients with LV systolic dysfunction and subsequent recovery of LV ejection fraction (LVEF) in the acquired heart disease population. The purpose of this study was to assess the relationship between LVGLS and cardiovascular events (heart failure hospitalization, sustained ventricular tachycardia/appropriate shock, heart transplant, or cardiovascular death) and deterioration in LVEF (absolute decrease in LVEF ≥10% to LVEF <50%) in adults with congenital heart disease. Methods: Retrospective cohort study of congenital heart disease patients with previous diagnosis of LV systolic dysfunction (LVEF <50%) and subsequent recovery of LVEF (absolute increase in LVEF of ≥10% to LVEF ≥50%) on subsequent echocardiogram (index echocardiogram). Based on the index echocardiogram, patients were divided into normal LVGLS (absolute LVGLS >18%) versus abnormal LVGLS (absolute LVGLS ≤18%) groups. Results: Of 193 patients with recovered LVEF, 86 (45%) had normalization of LVGLS at index echocardiogram. A higher absolute LVGLS and use of renin angiotensin aldosterone system antagonist was associated with a lower risk of cardiovascular events and subsequent deterioration in LVEF, while hypertension was associated with higher risk of cardiovascular events and deterioration in LVEF. Conclusions: These results suggest that patients with congenital heart disease with recovered LVEF remained at risk for adverse outcomes, and LVGLS can be used to identify patients at risk for adverse outcomes. Medical therapy for heart failure and treatment of hypertension may reduce the risk of adverse outcome, but these findings require empirical validation, hence the need for a clinical trial.
