P1827 Impact of coronary microcirculatory dysfunction in the impairment of left ventricular deformation parameters by 4D echocardiographic techniques in hypertrophic cardiomyopathy patients

Background Coronary microvascular dysfunction has been described as an important pathophysiologic feature in hypertrophic cardiomyopathy (HCM). Objective To analyse the impact of coronary microcirculatory dysfunction on left ventricular (LV) deformation parameters obtained by 4D echocardiography in HCM. Methods HCM patients (P) prospectively underwent dedicated transthoracic echocardiogram for microcirculation study. The evaluation of coronary...
