Patients with aneurysms 7 cm or greater demonstrated a higher probability of survival when treated immediately, compared to delayed repair, for patients under 80 years of age.

An interesting attempt to construct a decision tool for aortic aneurysms.

This original article retrospectively analyzes the outcome of 359 patients after TEVAR at seven centers. All patients were stratified regarding the modified arch landing nomenclatur (MALAN). The rate of proximal endograft failure was significantly lower in patients with favorable landing area (MALAN 2/III and 3/III). Regarding these results, the MALAN classification can be used to guide decisions in pre-TEVAR planning.

This succinct article reviews the contemporary literature regarding sex differences in thoracic aortic disease including the epidemiology, biology, natural history, surgical management and outcomes. Furthermore, the authors propose explanations for the observed differences and puts out a call to action to close the gender gap in sex differences in thoracic aortic disease.

The present study reports on the multicenter cohort of patients from the Sutureless and Rapid-Deployment Aortic Valve Replacement International Registry who underwent minimally invasive reoperative aortic valve replacement with a sutureless or rapid-deployment prosthesis. This study demonstrates the safety and feasiblitity of minimally invasive reoperative aortic valve replacement with a sutureless or rapid-deployment prosthesis.

The authors created 612 matched pairs of patients with a history of hematologic malignancy and controls. They compared operative details, early postoperative complications, and late survival.

Patients with prior diagnosis of malignancy had lower hemoglobin levels and were at greater risk of receiving postoperative blood transfusions (47.4% vs. 35.6%, P<0.0001).
Reoperations for postoperative bleeding (4.7% vs. 3.3%, P=0.253) and stroke (1.3% vs. 1.3%, P>0.999) were similar. Thirty-day mortality in patients with hematologic malignancy was 3.3%, and 1.5% in matched controls (P=0.061).
Overall survival among patients with cancer was reduced (P<.0001).

The authors concluded that while late survival is reduced in patients with hematologic malignancies, early outcomes are generally similar to matched controls. As such, these patients should be offered surgery.

The authors comducted a comparative analysis of the Trifecta and Perimount Magna Ease bioprosthetic valves, using data from a national Finnish database between 2008 and 2017.

They included 2216 patients, with a mean follow-up 3.8±2.1 years. 851 patients received the Trifecta valve and 1365 received the Perimount Magna Ease bioprosthesis. The rates of late mortality and prosthetic valve endocarditis were comparable in the study cohorts. At 7-year, the Trifecta cohort had significantly higher risk of repeat aortic valve replacement for structural valve failure (3.3% vs. 0%), repeat aortic valve replacement for any cause (3.6% vs. 0.4%) and repeat aortic valve replacement and/or prosthetic valve endocarditis (4.1% vs. 0.9%) compared to the Perimount Magna Ease cohort.
Among 772 propensity score matched pairs, at 7-year, the Trifecta cohort had a higher risk of repeat aortic valve replacement for structural valve failure (5.7% vs. 0%).

The authors report that the Trifecta aortic bioprosthesis is associated with a higher occurrence of repeat aortic valve replacement for structural valve failure compared to the Perimount Magna Ease bioprosthesis.
