Hi Brian,

Hope this finds you well, I am working on the grant application for PCORI as I mentioned to you earlier. So more information will be coming in the next week.

“Also, I recently published these manuscripts recently that you may find to be of interest to your readership’

Association of variant arch anatomy with type B aortic dissection and hemodynamic mechanisms


· Type of Research: Retrospective cohort study

· Take Home Message: Compared with 367 controls, variant arch anatomy was observed on computed tomography scans of 40.5% of 185 patients with type B aortic dissection. On four-dimensional flow magnetic resonance imaging, patients with bovine arch had higher systolic wall shear stress compared with those with normal arch anatomy.

· Recommendation: This study suggests that aortic arch anatomy variants are more common in patients with type B aortic dissections, which might be explained by higher wall sheer shear stress.

Endovascular thoracic aortic repair in confirmed or suspected genetically triggered thoracic aortic dissection


· Type of Research: Retrospective analysis of prospectively collected National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) data

· Take Home Message: In 31 patients with descending thoracic aorta dissection treated with thoracic endovascular aortic repair, 13 (42%) required reintervention at a median of 7 months, 3 for retrograde ascending aorta dissection and 7 for thoracoabdominal aortic aneurysm repairs with stent graft explantation.

· Recommendation: This study suggests that patients with genetically triggered descending thoracic aorta dissection, treated with thoracic endovascular aortic repair, have a high risk of retrograde aortic dissection and reintervention.

Testing patterns for genetically triggered aortic and arterial aneurysms and dissections at an academic center


· Type of Research: Retrospective cohort study

· Take Home Message: In 36% of 75 patients suspected of having heritable mutations related to aortic or arterial aneurysms or dissections, genetic testing results were positive. Pathogenic mutation was confirmed in 57% of patients with a family history of diagnosed mutation and in 42% of those with a personal history of ascending aortic disease.

· Recommendation: The authors suggest appropriate genetic consultation and selective testing in patients suspected of having genetically triggered vascular disease and suggest the need for novel gene discovery.
