HEART HEALTHY BUT HYPERTENSIVE: A CASE OF PULMONARY HYPERTENSION CAUSED BY HIGH OUTPUT HEART FAILURE SECONDARY TO ARTERIAL VENOUS MALFORMATION

Background Arteriovenous malformations rarely cause congestive heart failure. Pregnancy may in theory trigger heart failure associated with congenital arteriovenous malformations leading to secondary pulmonary hypertension, but no cases have been reported proving that condition. Methods and results We report a 23-year-old pregnant woman at 36 + 5 weeks of gestation requiring urgent medical care because of shortness of breath. High-output heart failure was suspected, and a congenital arteriovenous malformation on the right scapular region was considered as the possible origin. The patient required urgent caesarean delivery because of ongoing cardiac failure, which improved soon after delivery. Postpartum angiography of the right subclavian artery revealed an arteriovenous malformation on the deltoid region with venous drainage through the subclavian vein and increased flow to the superior cava vein and right atrium. Conclusion A high index of suspicion of arteriovenous malformations should be maintained in pregnant women with cutaneous vascular malformation-like lesions, if symptoms of heart failure are present.

Abstract Background Infantile hepatic hemangioma (IHH) is a rare endothelial cell neoplasm, which may be concurrent with severe complications and result in poor outcomes. Moreover, the coexistence of IHH and congenial heart disease is even rarer. Case presentation We present a 10-day-old male born with IHH associated with patent ductus arteriosus (PDA), atrial septal defect (ASD) and pulmonary hypertension. Moreover, we reviewed a series of studies of IHH-associated high-output cardiac failure between 1974 and 2018, and summarized the treatment outcomes. Conclusions Infantile hepatic hemangioma (IHH) has been known to induce high-output heart failure. There is no literature to summarize the severity of its impact on heart, which can lead to a high mortality rate. When IHH is detected by ultrasound, the heart should be evaluated to facilitate treatment. The outcomes of IHH associated with heart failure are good.
