DEXTROCARDIA

TYPES AND CLINICAL FEATURES

  1. TRUE DEXTROCARDIA (WITH SITUS INVERSUS)

Here there is mirror image transposition of the cardiac chambers, i.e., left atrium and ventricle on the right side and right atrium and ventricle on the side. This is usually associated with mirror-image transposition of the abdominal viscera. Symptoms are usually absent. In some of these cases there may be frontal sinusitis or absence of frontal sinuses and bronchiectasis (Kartagener’s syndrome).

  1. ISOLATED DEXTROCARDIA (WITHOUT SITUS INVERSUS):

There is mirror- image transposition of the cardiac chambers but no situs inversus. Various types of cardiac anomalies are present and hence patients usually have some symptoms.

  1. FALSE DEXTROCARDI OR DEXTROVERSION:

There is no mirror-image transposition of the cardiac chambers. Heart is merely displaced to the right side of the chest. Serious cardiac anomalies may be associated with it.

  1. SECONDARY DEXTROCARDI

Here the heart is displaced to the right side of the chest from various thoracic disease like fibrosis or collapse of right lung and increased intrapleural pressure on the left side.

INVESTIGATIONS

ECG and X-ray of chest and two dimensional Echocardiography will help in the diagnosis regarding position of ventricle and great vessels.
