AI Article Synopsis
- The study investigates the outcomes of transcatheter aortic valve replacement (TAVR) in patients with aortic stenosis and unruptured thoracic aortic aneurysm (TAA), finding that TAA patients are generally younger and more likely to have bicuspid aortic valves.
- It reveals that patients with TAA face a higher risk of severe complications such as aortic dissection and cardiac tamponade after TAVR.
- The findings suggest that healthcare teams need to carefully evaluate the risks when considering TAVR for patients with unruptured TAA.
Article Abstract
Background: The use of transcatheter aortic valve replacement (TAVR) has expanded to patient populations of varying surgical risk in light of recent clinical trials, yet its role in patients with aortic stenosis and coexisting thoracic aortic aneurysm (TAA) is not well-delineated. We aimed to evaluate whether risk factors and in-hospital outcomes vary between TAVR patients with and without an unruptured TAA.
Methods: The Nationwide Readmissions Database was queried for patients hospitalized between January 2012 and December 2017 who underwent TAVR with and without an unruptured TAA. In-hospital outcomes were compared between cohorts after adjusting for sex, comorbidities, and TAVR approach, and in a subgroup analysis that excluded those with bicuspid aortic valves.
Results: Among 171,011 TAVR patients, 1,677 (1%) presented with TAA. Patients with TAA were younger (median age 80 vs. 82 years, p < .001) and more likely to have bicuspid aortic valves (9.3% vs. 0.9%, p < .001). Among patients with aneurysm, 2.6% died, 2.2% developed stroke, 1% developed aortic dissection, and 1.4% experienced cardiac tamponade while hospitalized. After adjusting for age, sex, bicuspid aortic valve, and all comorbidities, TAA was associated with significantly higher risk of post-TAVR aortic dissection (OR = 2.117, 95% CI [1.304-3.435], p = .002) and cardiac tamponade (OR = 1.682, 95% CI [1.1-2.572], p = .02).
Conclusions: While the overall incidence of post-TAVR complications is low, patients with an unruptured TAA should be carefully considered by the Heart Team in weighing the additional risks of aortic dissection and cardiac tamponade after TAVR with those associated with surgery.

Background: Abdominal aortic aneurysm (AAA) is more common in Non-small cell lung cancer (NSCLC) patients. Considering that ruptured AAA is potentially fatal, timely management of AAA would result in long-term survival benefits. We assess the prevalence and characteristics of AAA in resectable NSCLC patients who would benefit from AAA surveillance.

Importance: It remains unknown whether outcomes of the Placement of Aortic Transcatheter Valves 3 (PARTNER 3) and Evolut Low Risk trials are comparable with surgical outcomes in nontrial settings, considering the added risk of concomitant cardiac operations.
Objective: To compare 30-day mortality and stroke incidences of patients in the surgical aortic valve replacement (SAVR) arm of low-risk trials with those of similar patients in the US Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD).
Design, Setting, And Participants: A cross-sectional sampling study was conducted of adults in the STS ACSD with severe aortic stenosis at low surgical risk for AVR who underwent SAVR during the years low-risk AVR trials (PARTNER 3 and Evolut Low Risk) were enrolling (calendar years 2016-2018).
Fluid-structure-growth modeling in ascending aortic aneurysm: capability to reproduce a patient case.

Predicting the evolution of ascending aortic aneurysm (AscAA) growth is a challenge, complicated by the intricate interplay of aortic geometry, tissue behavior, and blood flow dynamics. We investigate a flow-structural growth and remodeling (FSG) model based on the homogenized constrained mixture theory to simulate realistic AscAA growth evolution. Our approach involves initiating a finite element model with an initial elastin insult, driven by the distribution of Time-Averaged Wall Shear Stress (TAWSS) derived from computational fluid dynamics simulations.

Heritable thoracic aortic disease is caused by dominantly inherited mutations in more than a dozen genes, including mutations that cause Loeys-Dietz syndrome. McGovern Medical School at UTHealth Houston convenes a regular conference that includes cardiothoracic and vascular surgeons, cardiologists, geneticists, radiologists, and pathologists to formulate multidisciplinary approaches for the management of complex heritable thoracic aortic disease cases. In this report, we highlight the unique management of individuals with distinct presentations of Loeys-Dietz syndrome owing to mutations.

In the past 15 years, fenestrated-branched endovascular aortic repair (F-BEVAR) has progressively become the first-line option for management of most complex abdominal aortic aneurysms (AAAs); with increasing experience, as well as persistent technological refinements, F-BEVAR indications have been expanded to include rescue of failures after prior EVAR. Despite the feasibility and effectiveness, F-BEVAR procedures in the presence of prior infrarenal endografts may come with higher technical complexity that should be properly anticipated, and several anatomical challenges can be expected. Among these, presence of suprarenal bare stents from prior EVAR device are certainly a frequent scenario and may sometimes make target vessel cannulation more difficult because of encroachment on the target vessel origins.
