Idiopathic Isolated Right Ventricular Apical Hypertrophy.

A 50 year old male, asymptomatic, normotensive patient on routine medical evaluation was found to have inverted T-waves on the electrocardiogram (Figure 1). He had no history of angina or any other symptoms. However, despite complete lack of symptoms, because of the abnormality on the electrocardiography (ECG) an echocardiography was carried out for further evaluation. Echocardiography revealed focal hypertrophy of the right ventricular (RV) apex almost obliterating the apex (Figure 2A) but sparing the inter-ventricular septum. There was no concomitant left ventricular hypertrophy (wall thickness 1.1 cm) (Figure 2B) and there was no pulmonary valve stenosis (gradient across pulmonary valve: 2 mmHg). Tricuspid annular plane systolic excursion was measured (24 mm) and was normal. Pulsed tissue Doppler applied to the RV free wall at the tricuspid annular level and at the septal and lateral corners at the mitral annular level revealed normal velocities (10 cm/sec and 12 cm/sec respectively). There was no outflow obstruction or decreased RV compliance or RV dysfunction.
