Severe RV dilatation may occur with isolated incomplete RBBB; leaves open causal confirmation and management implications.
Because of an incomplete right bundle branch block, a severe right ventricular dilatation with no left ventricular cardiomyopathy was found in a 44-year-old man. Magnetic resonance and transesophageal echocardiography confirmed the finding and these tests also failed to find any potential cause. A pulmonary hemodynamic study and a coronary angiography were strictly normal. Lastly pulmonary function tests and a pulmonary angiography were performed, which did not find any lung disease causing the right ventricular dilatation. The patient was catalogued as an early stage of an idiopathic form of right ventricular dilated cardiomyopathy.

Figuero et al. (2015) conducted a case report in Idiopathic right ventricular dilated cardiomyopathy (n=1). Watchful waiting was evaluated on Symptom progression and right ventricular dilatation. After 2 years of follow-up, the patient with early-stage idiopathic right ventricular dilated cardiomyopathy remained asymptomatic with persistent right ventricular dilatation.
