AbstractPurposePatients with Ebstein anomaly (EA) have a variety of clinical manifestation. The assessment of structural and geometric characteristics of the heart is important for optimal management.MethodsWe retrospectively analyzed echocardiography database from 2009 to 2020. We evaluate patients in two groups: patients with EA were in Group 1 and children without cardiovascular pathology were in Group 2. All children in both groups underwent echocardiography according to American Society of Echocardiography recommendations. The shape of the heart chambers and their function were studied in both groups.ResultsThere were 153 in Group 1 and 2000 children without cardiovascular disease in Group 2. It was shown that in children with EA, the shape of the ventricle became less spherical, which was accompanied by a decrease in myocardial mass, and the ejection fraction was reduced 34% of patients. The functional volume (non‐atrialized part) of the right ventricle in patients with EA was reduced, and its contractility was preserved in 62% of cases. Preservation of the contractile properties of the right ventricle in most cases was associated with higher systolic pressure in its cavity.ConclusionTAPSE, TESV, and the velocity of the annulus fibrous ring movement according to tissue dopplerography in patients with EA do not allow us to assess the contractility of the right ventricle. The myocardial performance index (MPI) characterizes a decrease in the functional volume of the right ventricle.

This clinical case report describes surgical management of a giant left ventricular fibroma and postoperative venoarterial extracorporeal membrane oxygenation support in a newborn male. Transthoracic echocardiography performed at 9-month follow-up showed an ejection fraction of 33% and a cardiac index of 4.5 liters per minute per square meter.
