Coarctation of the aorta (CoA) is a relatively common congenital heart anomaly, and bicuspid aortic valve (BAV) is a common congenital heart disease that coexists with CoA. In larger children and adults with CoA, transcatheter intervention has gained acceptance, but for surgical high-risk patients with aortic stenosis, the use of transcatheter aortic valve implantation (TAVI) has been established. Recently, although favorable data have been reported for TAVI when treating BAV, simultaneous transcatheter intervention for CoA and BAV will prove to be a challenge because of the unique anatomy involved requires multiple procedural steps and also has problems of site access...

Aortobronchial fistula (ABF) is a rare condition which can be lethal if left untreated. Open surgical treatment carries high morbidity and mortality. Recent advances in endovascular technology have made thoracic endovascular aortic repair (TEVAR) the treatment of choice. We present a successful endovascular repair of aortobronchial fistula due to a saccular aneurysm of descending thoracic aorta.

Massive hemoptysis caused by bronchiectasis threatens life, so early bronchial arterial embolization (BAE) is needed. In case 1, a 80-year-old female complained of hemoptysis and back pain caused by bronchiectasis and Stanford type B aortic dissection. In case 2, a 78-year-old male had history of the surgery of descending thoracic aortic aneurysm and bronchiectasis combined with aortopulmonary fistula. Both cases in bronchiectasis with massive hemoptysis were difficult to perform BAE due to complicated with acute aortic dissection and aortopulmonary fistula...

An 83-year-old man with aortic arch aneurysm underwent zone 0 thoracic endovascular aortic repair (TEVAR) by the chimney graft technique with two supra-aortic arch debranching grafts and developed subacute type A ascending aortic dissection. We performed emergency open conversion with circulatory arrest under deep hypothermia. The tip of the chimney graft (around the sino-tubular junction in the ascending aorta) was stiff, making it difficult to inspect the lumen and perform anastomosis. Deep hypothermic circulatory arrest and cutting the endograft stents to mobilize the graft were necessary for secure anastomosis...

PURPOSE: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment of descending thoracic aorta pathology. However, TEVAR in the aortic arch remains challenging. Customized fenestrated TEVAR (fTEVAR) allows extension of the proximal seal zone, while preserving the involved supra-aortic vessels. There is a paucity of information on fTEVAR; hence, we aim to evaluate our early experience and lessons learnt with fTEVAR in the aortic arch. METHODS: This is a retrospective single-centre review of fTEVAR endografts for aortic arch pathology over 24 months...

Thoracic endovascular repair (TEVAR) is an effective treatment for type B aortic dissection (TBAD). Here, we evaluated the early-midterm effectiveness and safety of TEVAR for treating TBAD patients after renal transplantation. Six patients with TBAD treated with TEVAR after renal transplantation were recruited between February 2012 and December 2016. They were then followed up with clinical examinations and computed tomography angiography (CTA). TEVAR was successfully performed in all patients (100%), and the primary tear sites were well covered by stents with or without coverage of the left subclavian artery...
