Abstract
Aim. To present a clinical case of myocardial hypertrophy with intracavitary left ventricular obstruction in a premature newborn. Materials and Methods. The article describes a clinical case of myocardial hypertrophy with left intraventricular cardiac obstruction. Myocardial hypertrophy with left intraventricular cardiac obstruction in newborns is a life-threatening condition requiring timely diagnosis and therapy. Results. One of the means of diagnosing and monitoring this condition is target echocardiography, which allows it to be diagnosed, to correct hemodynamic components and to evaluate the effectiveness of therapy, including the use of beta-blockers. Myocardial hypertrophy with left intraventricular cardiac obstruction was diagnosed based on an ultrasound picture of thickening of the myocardial walls and the presence of an intraventricular gradient of 11 mmHg. The hemodynamic profile of this condition was characterized by a decrease in preload and postload, as well as an increase in myocardial contractility. Treatment included increased liquid load, the use of the vasopressor norepinephrine, and the administration of the beta-blocker atenolol. Against the background of the therapy, regression of the obstruction of the excretory tract of the left ventricle and clinical stabilization of the child were achieved. Conclusion. Target echocardiography has demonstrated its clinical effectiveness in the detection and control of therapy for myocardial hypertrophy with left intraventricular cardiac obstruction.
