Left Ventricular Compression By a Thoracic Aortic Aneurysm

An 83-year-old man presented with a symptomatic contained rupture of a thoracoabdominal aortic aneurysm and type I endoleak of a previously repaired aneurysm.

The patient underwent deployment of an aortic stent graft but died on postoperative day 5 from surgical complications. Click the article link for full case details.
