1 Angioclub Case Series: Aortic Pathology Candace L. White MA, MD Mount Sinai Medical Center of Florida

2 Patient Presentation 79 y male, retired urologist CC: acute onset of substernal chest pain HPI: patient was watching the superbowl when he experienced acute onset and progressive substernal chest pain with radiation to back MHx: CAD, severe HTN, noted medication non-compliance

3 Workup/Clinical Integration ER EKG Cardiac Enzymes CT Chest w +w/o Cardiology ICU admission for BP control TEE Cardiothoracic Surgery Interdisciplinary discussion of treatment options with patient/family Interventional Radiology Intervention

4 Non-Invasive Imaging Intramural Hematoma of the Ascending Thoracic Aorta and Arch (Type A) *no dissection flap identified

5 Non-Invasive Imaging Penetrating Ulcer of the Descending Thoracic Aorta

6 Diagnosis CT demonstrates Type A intramural hematoma involving the ascending aorta and aortic arch with suspect point of origin at a penetrating ulcer immediately distal to the L subclavian artery origin TEE confirmed intramural hematoma without distinct dissection flap, lack of involvement of the coronary arteries or cardiac sinuses, and absence of pericardial effusion

7 Management Options  Medical Management strict BP control  Surgical Management immediate vs delayed repair of ascending aorta +/- repair of transverse aortic arch  Endovascular Management endovascular stent graft

8 Review of Literature  Vast majority of studies report: significantly high rate of progression of Type A IMH to aortic dissection, aneurysm, or rupture significantly increased mortality with medical management compared to surgical management  Few studies report: resolution of IMH without progression to more malignant processes, in a select population  TWO studies report: successful management of Type A IMH with endovascular approach studies consist of 4 and 8 patients

9 Definitive Treatment Patient refused open repair Interdisciplinary decision was made to intervene with endovascular approach to prevent progression of disease process TEVAR using 40mm x 40mm x 15cm endograft placed just distal to the L subclavian artery origin to cover the penetrating ulcer, thought to be the origin of the IMH

10 Follow-up Imaging at 3 months post TEVAR demonstrates complete resolution of Type A IMH without evidence of progression to dissection flap, aneurysm, or rupture
