Hereditary Hemorrhagic Telangiectasia with SMAD4 Mutations is Associated with Fatty Degeneration of the Left Ventricle, Coronary Artery Aneurysm, and Abdominal Aortic Aneurysm.

Hereditary Hemorrhagic Telangiectasia with SMAD4 Mutations is Associated with Fatty Degeneration of the Left Ventricle, Coronary Artery Aneurysm, and Abdominal Aortic Aneurysm. Intern Med. 2018 Sep 12;: Authors: Inoguchi Y, Kaku B, Kitagawa N, Katsuda S Abstract A 52-year-old man with recurrent epistaxis and palpebral conjunctival telangiectasia visited our hospital for a follow-up checkup for gastrointestinal polyposis. At 48 years of age, he underwent Y-graft replacement for an abdominal aortic aneurysm. Arteriovenous malformation (AVM) was detected in his lungs, and a genetic test revealed an SMAD4 mutation. Eventually, he was diagnosed with juvenile polyposis-hereditary hemorrhagic telangiectasia (JP-HHT) syndrome. In addition, fatty degeneration of the left ventricle (LV) and a coronary aneurysm were detected. This is the first report suggesting the possibility of an association between these manifestations and JP-HHT due to SMAD4 mutations. Examining cardiovascular disorders in JP-HHT patients is imperative. PMID: 30210120 [PubMed - as supplied by publisher]
