Ebstein anomaly is an uncommon congenital cardiac anomaly, characterized by a variable developmental anomaly of the tricuspid valve. Epidemiology The anomaly accounts for only ~0.5% of congenital cardiac defects 6,7, although it is the most common cause of congenital tricuspid regurgitation. T...

The moderator band, also called the septomarginal trabecula, is a consistent structure in the morphologic right ventricle and can be helpful as a landmark in situations where the ventricles may be ambiguous (i.e. in some forms of congenital heart disease). The term "septomarginal" is descriptiv...

Mean pulmonary arterial pressure (mPAP or MPAP) can be estimated by echocardiography, although the gold standard remains measurements taken directly during right heart catheterization. It is calculated by the formula: (PASystolic pressure +2 PADiastolic pressure) / 3 The pulmonary arterial sys...

The McConnell's sign describes a regional pattern of acute right ventricular dysfunction on transthoracic echocardiography first observed in a cohort of patients with acute pulmonary thromboembolism. In contrast to the global wall motion abnormalities observed in chronic right ventricular dysfun...

The 60/60 sign in echocardiography refers to the coexistence of a truncated right ventricular outflow tract acceleration time (AT <60 ms) with a pulmonary arterial systolic pressure (PASP) of less than 60 mmHg (but more than 30 mmHg). In the presence of right ventricular failure, it is consisten...
