Atrial and Ventricular Functional and Structural Adaptations of the Heart in Elite Triathletes Assessed with Cardiac MR Imaging

Abstract

Changes in cardiac morphologic characteristics and function in elite triathletes, as measured with cardiac MR imaging, reflect a combination of eccentric and concentric remodeling with regulative enlargement of atrial and ventricular chambers. These findings are different from what has been observed in previous studies in other types of elite athletes.
