Introduction Endovascular fenestration is used to manage complicated aortic dissection in a manner analogous to open surgical septectomy. The intent to create a large communication between the aortic true and false lumina providing free interluminal flow and equalization of pressure…
Introduction Since its inception in 1992, thoracic endovascular aortic repair (TEVAR) was introduced as an alternative treatment option to conventional open surgery for patients with complicated Type B aortic dissection (TBAD), i.e., end-organ malperfusion, refractory hypertension or hypotension, and unrelenting…
Transcatheter Aortic Valve Replacement Introduction Aortic stenosis (AS) affects morbidity and mortality as populations continue to age. Recent studies have estimated the prevalence of calcific AS between 2% and 4% among adults over 65 years of age and, for many…
Introduction Over the last two decades, endovascular aortic repair (EVAR) has become the preferred treatment with regard to aortic pathologies and is an alternative treatment for patients who do not qualify for open surgery. Although EVAR has been shown to…
Introduction and Background The introduction of thoracic stent grafts into clinical practice over the past two decades and the ability to image the thoracic aorta in high definition have offered a paradigm shift in the way we have been able…
Introduction Bolton Medical (Sunrise, Florida), now owned by Terumo (Tokyo, Japan), introduced the Relay thoracic endovascular aortic repair (TEVAR) endograft in 2005, with Phase II trials for approval in the United States beginning in 2007. In 2009, RelayPlus was introduced,…
Introduction Since the advent of endovascular abdominal aortic aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA), the rate of technical proficiency has reached impressive levels, with modern reports reaching 99%–100% of endografts successfully placed during initial treatment. However, despite technical…
Introduction The Conformable TAG (CTAG) endoprosthesis (WL Gore and Associates, Flagstaff, Arizona) is the third-generation thoracic endograft approved for treatment of aneurysm, traumatic transection, and Type B dissection in the descending thoracic aorta. The second-generation TAG endoprosthesis was the first…
Introduction Thoracic endovascular aortic repair (TEVAR), first performed in 1992, has become the treatment of choice for the majority of thoracic aortic pathologies, including thoracic aortic aneurysms (TAAs) and complicated Type B aortic dissections (TADs). Presence of an endoleak is…
Endovascular repair of thoracoabdominal aortic aneurysms requires long segment stent graft coverage with concomitant revascularization of the renovisceral and potentially supraaortic arch segments. Such procedures represent the highest extent of complex endovascular therapy and are associated with increased technical demand,…
