Levoatrial cardinal vein (LACV) is anomalous connection between left atrium or pulmonary veins and systemic veins such as innominate vein or superior vena cava. This persistence of splanchnic circulation occurs when there is left-sided obstructive cardiac lesions such as hypoplastic left heart or mitral atresia. In this report we present three cases of LACV with well-developed left heart, without any obstructive lesions. All our cases presented with pulmonary arterial hypertension (PAH) and had associated intracardiac shunt such as ventricular/atrial septal defect and supracardiac partial anomalous pulmonary venous connection. Apart from the above shunts, LACV contributed to PAH in these cases. It is important to detect and report LACV as this may require surgical correction along with other defects. If LACV goes undetected during imaging workup, it may cause persistent PAH postoperatively.
