Indirect Pulmonary Artery Pulse Diagnostic Significance in Transposition of Great Vessels

The indirect pulmonary artery pulse in the second right intercostal space, hitherto undescribed, was reported in a case of complex congenital heart disease with transposition of great vessels, atrial septal defect, tricuspid atresia, ventricular septal defect and pulmonary hypertension. It was illustrated that the indirect pulmonary artery pulse in the second right intercostal space indicates the existence of the transposed great vessels. In addition, the significance of the precordial impulse in the third left sternal border was discussed.
