Difficult case of right ventricular pathology diagnostics. Double-chamber right ventricle

Right ventricular pathology diagnostics often causes difficulties. The article presents a clinical case of difficulty in verifying a two-chamber right ventricle. A patient with a history of resection of aortic coarctation but uncorrected ventricular septal defect eventually developed high-velocity flows in the right ventricle cavity, diagnosed by transthoracic echocardiography, which were regarded as manifestations of intraventricular obstruction in hypertrophic cardiomyopathy of the right ventricle. During additional examination, discrepancies arose in establishing the final diagnosis. Differential diagnosis was made between hypertrophic cardiomyopathy of the right ventricle, non-compact cardiomyopathy of the right ventricle and a two-chamber right ventricle.
