- Right ventricular dilatation
- Right ventricular dilatation (RVD)
Right ventricular enlargement (also known as right ventricular dilatation (RVD)) can be the result of a number of conditions, including:
- pulmonary valve stenosis
- pulmonary arterial hypertension
- atrial septal defect (ASD)
- ventricular septal defect (VSD)
- tricuspid regurgitation
- dilated cardiomyopathy
- anomalous pulmonary venous drainage
- tetralogy of Fallot
Clinical presentation
ECG
- right axis deviation
- secondary repolarization (ST-T) abnormalities (leads V1-3)
- deep S waves in lateral (I, aVL, V5-6) leads
- tall, prominent R waves in lead V1
- may be masked in the presence of COPD
Radiographic features
Plain radiograph
Frontal view demonstrates:
- rounded left heart border
- uplifted cardiac apex
Lateral view demonstrates:
- filling of the retrosternal space
- rotation of the heart posteriorly
Echocardiography
On transthoracic echocardiography the apical 4 chamber (A4C) view allows a qualitative assessment of the presence or absence of right ventricular enlargement, as well as the degree of severity 4:
- mild RV enlargement
- basal diameter increased (>4.2 cm)
- left ventricular size still exceeds that of the RV
- moderate RV enlargement
- the size of the RV approximates that of the left ventricle (LV)
- the left ventricle still forms apex
- severe RV enlargement
- the RV forms the apex and is larger than the LV
