Improving outcomes of surgery for acute type A aortic dissection.

It remains equivocal if acute type A aortic dissection (ATAAD) surgical outcomes are improving. We analyzed current outcome trends to evaluate improvements and to identify predicting variables. From 2015 to 2020, 204 patients underwent surgery for ATAAD and were divided into recent ( = 102) and earlier ( = 102) groups.

Impact of national holidays and weekends on incidence of acute type A aortic dissection repair.

Previous studies have demonstrated that environmental and temporal factors may affect the incidence of acute type A aortic dissection (ATAAD). Here, we aimed to investigate the hypothesis that national holidays and weekends influence the incidence of surgery for ATAAD. For the period 1st of January 2005 until 31st of December 2019, we investigated a hypothesised effect of (country-specific) national holidays and weekends on the frequency of 2995 surgical repairs for ATAAD at 10 Nordic cities included in the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) collaboration.

Type A Aortic Dissection Repair in Patients With Prior Cardiac Surgery.

Background: Emergency surgery for acute type A aortic dissection in patients with previous cardiac surgery is controversial. This study aimed to evaluate the association between previous cardiac surgery and outcomes after surgery for acute type A aortic dissection, to appreciate whether emergency surgery can be offered with acceptable risks.

Methods: All patients operated on for acute type A aortic dissection between 2005 and 2014 from the Nordic Consortium for Acute Type A Aortic Dissection database were eligible.

Once after a full moon: acute type A aortic dissection and lunar phases.

Objectives: Acute type A aortic dissection (ATAAD) is a rare but severe condition, routinely treated with emergent cardiac surgery. Many surgeons have the notion that patients with ATAAD tend to come in clusters, but no studies have examined these observations. This investigation was undertaken to study the potential association between the lunar cycle and the incidence of ATAAD.

A randomized prospective multicenter trial for stroke prevention by prophylactic surgical closure of the left atrial appendage in patients undergoing bioprosthetic aortic valve surgery--LAA-CLOSURE trial protocol.

Patients undergoing surgical aortic valve replacement (SAVR) are at high risk for atrial fibrillation (AF) and stroke after surgery. There is an unmet clinical need to improve stroke prevention in this patient population. The LAA-CLOSURE trial aims to assess the efficacy and safety of prophylactic surgical closure of the left atrial appendage for stroke and cardiovascular death prevention in patients undergoing bioprosthetic SAVR.

ABO blood group does not impact incidence or outcomes of surgery for acute type A aortic dissection.

To evaluate the distribution and impact of ABO blood groups on postoperative outcomes in patients undergoing surgery for acute type A aortic dissection (ATAAD). . A total of 1144 surgical ATAAD patients from eight Nordic centres constituting the Nordic consortium for acute type A aortic dissection (NORCAAD) were analysed.

Evolution of Left Ventricular Size in Late Survivors of Surgery for Hypoplastic Left Heart Syndrome.

Background: Aortic atresia and mitral atresia are predictors of adverse events in early life in patients with hypoplastic left heart syndrome, but it is unclear whether late outcomes are also affected, and whether this impact is related to a small hypertrophied left ventricle (LV) that impairs right ventricle (RV) function.

Methods: Thirty patients with hypoplastic left heart syndrome surviving with a Fontan procedure were identified. Follow-up echocardiograms were available at birth, before the Fontan procedure, and several years after.

Outcomes of aortic arch repair with extended (≥ 90 minutes) antegrade cerebral perfusion.

Objectives: To analyze outcomes with extended duration of antegrade cerebral perfusion (ACP) during hypothermic circulatory arrest (HCA) for total arch repair (TAR).

Design: Retrospective study of consecutive patients undergoing TAR with HCA and ACP. Patients were divided into group A (ACP ≥ 90 min, n = 12) and group B (ACP < 90 min, n = 17) and compared regarding in-hospital mortality and neurological complications (primary outcome measures) and major complications, biochemical markers of organ damage, and blood product use (secondary outcome measures).
