Abstract
Pregnancy complicated with hereditary haemorrhagic telangiectasia (HHT) is a rare
condition. This case report presents an extremely rare case with the
co-occurrence of HHT and congenital heart disease. In this report, a 43-year-old
woman at 36 + 4 weeks of gestation experienced haemoptysis with a volume of
approximately 300 ml for the first time. Uncommonly, her transthoracic
echocardiogram revealed a previously unrecognized atrial septal defect (ASD) and
pulmonary hypertension (PH) for the first time at 36 + 1 weeks of gestation.
Chest computed tomography revealed an arteriovenous malformation (AVM) in the
right lower lobe of the lung. Due to concerns of rebleeding of ruptured
pulmonary arteriovenous malformations (PAVMs), the patient underwent a caesarean
section at 36 + 6 weeks of gestation. A healthy male infant weighing 2800 g was
delivered. To the best of our knowledge, there have been few reports about HHT
with ASDs and PH during advanced pregnancy. This current case report highlights
the necessity for clinicians to pay considerable attention to cardiac structural
abnormalities, which can worsen PAVM in patients with HHT during pregnancy, for
whom terminating the pregnancy in time may reduce the risk of PAVM rupture.
