Current management guidelines for ascending thoracic aortic aneurysms (aTAA) recommend intervention once ascending or sinus diameter reaches 5-5.5 cm or shows a growth rate of >0.5 cm/year estimated from echo/CT/MRI. However, many aTAA dissections (aTAAD) occur in vessels with diameters below the surgical intervention threshold ofMoreover, during aTAA repair surgeons observe and experience considerable variations in tissue strength, thickness, and stiffness that appear not fully explained by patient risk factors. To improve the understanding of aTAA pathophysiology, we established a multi-disciplinary research infrastructure: The Maastricht acquisition platform for studying mechanisms of tissue-cell crosstalk (MAPEX). The explicit scientific focus of the …

Hybrid Repair Strategies For Acute Type B Aortic Dissection Complicating Prior Standard And Complex Endovascular Aortic Repair, Jesse Chait, Bernardo C Mendes, Lily E Johnston, Fahad Shuja, Gustavo S Oderich, Manju Kalra

Journal Articles

Type B aortic dissection (TBAD) in the presence of an existing aortic endograft is a rare, but potentially catastrophic, event. False lumen pressurization and propagation leads to several failure modes. Endograft collapse can lead to spinal cord, visceral, or lower extremity ischemia, and rupture of a previously sealed aneurysm sac is often fatal. A successful treatment strategy must incorporate the patient's symptoms, urgency of intervention, extent of dissection, and the location and status of the existing graft. In this series, we present three cases of TBAD complicating prior endovascular aortic repairs-infrarenal, iliac branched, and thoracoabdominal branched endografts-successfully treated with tailored, …

Usefulness Of Computed Tomography Parameters In Predicting The Clinical Outcomes Of Acute Aortic Dissection, Eleanor Wei Sze Lee, Kwok Hin Yiu, Willis Chun Wai Lam, Cyrus Yiu Kwan Ko, Sung Yee Wong, Kin Wing Chan

Journal of the Hong Kong College of Cardiology

Background

Acute aortic dissection is a potentially life-threatening condition among patients presenting with chest pain to emergency department. Without a prompt diagnosis and treatment, it carries high mortality and morbidity. Computed tomography (CT) of thorax and abdomen is one of the commonly used non-invasive investigation modalities for diagnosis of acute aortic dissection. Apart from making a diagnosis, there are a number of parameters in the CT images that may be helpful in providing prognostic information. In this study, prognostic values of these parameters in predicting both short term and intermediate term clinical outcomes of acute aortic dissection will be evaluated. …

Mechanism Of Rare Variant In Acta2, P.Arg149cys, Driving Diverse Vascular Disease, Kaveeta Kaw

Dissertations & Theses (Open Access)

Heterozygous variants in ACTA2 (smooth muscle (SM) α-actin) predispose to thoracic aortic aneurysms and dissections (TAAD) and early-onset coronary artery disease (CAD). The most common ACTA2 mutation is a genetic alteration of arginine 149 to a cysteine, ACTA2 p.Arg149Cys, which accounts for disease in 24% of all ACTA2 mutation carriers.(1) ACTA2 p.Arg149Cys mutation carriers present with either TAAD or CAD but rarely have both diseases. To identify the molecular mechanisms dictating whether an individual with ACTA2 p.Arg149Cys develops TAAD or CAD, CRISPR/Cas9 technology was used to generate the mutant mouse, Acta2^R149C/+, in a C57BL6 background. Acta2^R149C/+ mice …

West Florida Division GME Research Day 2020

Aortic dissection (AD) is part of a group of acute aortic syndromes consisting of intramural aortic hematoma, penetrating aortic ulcer, and aortic rupture. On its own, the incidence is ~3 to 8 cases per 100,000 per year, and up to 25% of cases are missed. The in-hospital mortality when treated is 27%, and with a 2% increase in mortality/hour. Imaging modalities like CT angiography, TEE, and MRA have made improved diagnosis of the disease, but are costly, potentially harmful, time consuming, and require patient stability when in use (1). The key question we have as emergency department providers is if …

Anticoagulation With Bivalirudin During Deep Hypothermic Circulatory Arrest In A Patient With Heparin-Induced Thrombocytopenia, Agamemnon Pericleous, Mostafa Sadek, Mary Fitzmaurice, Constance Caldwell, Kris Natividad, Konstadinos A Plestis

The Texas Heart Institute Journal

Heparin-induced thrombocytopenia is a well-recognized complication of anticoagulation with heparin. We present the case of a patient with recent heparin-induced thrombocytopenia who subsequently needed surgery on an emergency basis for acute type A aortic dissection. This article reports the successful use of bivalirudin, a direct thrombin inhibitor, as an alternative to heparin throughout cardiopulmonary bypass and deep hypothermic circulatory arrest. We contend that bivalirudin is a safe alternative to heparin when performing surgery for aortic dissection and should be considered as an option for use in patients who present with heparin-induced thrombocytopenia.
