title: [Hypertrophic myocardiopathy (I). The clinical and echocardiographic characteristics of a population of 72 patients].
abstract: The results of the echocardiographic evaluation of 72 patients with hypertrophic cardiomyopathy are presented. We have measured left ventricular wall thickness in 8 different segments and classified our patients in 6 types according to the hypertrophy extent. Moreover, we have evaluated by Doppler ultrasound the presence and severity of mitral regurgitation and the left ventricular inflow and outflow. The hypertrophy cardiomyopathy pattern was symmetric in 8 patients, apical in five, and asymmetric in 31. According to Maron classification, asymmetric cardiomyopathy was I type: 4 patients, II type: 16, III type: 11, and IV type: 0 patients. There were left ventricular outflow obstruction (greater than 25 mmHg) in 26 patients (36.1%). This obstruction was more frequent in II and III type hypertrophic cardiomyopathy and we found significative relationship between septal posterior segment hypertrophy and left ventricular outflow obstruction. Ventricular inflow showed bad distensibility pattern in 45 patients (62.5%). Mitral regurgitation was mild, moderate and severe in 25, 15, and 4 patients. Left ventricular outflow obstruction, bad distensibility pattern and mitral regurgitation were independent each other.
