Increased Coronary Tortuosity Is Associated with Increased Left Ventricular Longitudinal Myocardial Shortening.

ABSTRACT:

Background

The mechanistic basis for tortuosity of the coronary arteries (TCA) is unclear. The aim of this study was to test the hypothesis that the relative degree of systolic longitudinal shortening of the left ventricle that deforms coaxially oriented coronary arteries is associated with TCA.

Methods

Adult subjects undergoing coronary angiography and comprehensive echocardiography within 3 months were classified dichotomously as with (n = 32) or without (n = 42) TCA defined on the basis of number and severity of coronary angles. Systolic left ventricular (LV) longitudinal deformation was determined by mitral annular plane systolic excursion (MAPSE) from both B-mode displacement and tissue Doppler time-velocity integral; data were indexed to LV diastolic long-axis length.<
