Temporal trends in mortality of aortic dissection and rupture in the UK, Japan, the USA and Canada.

Objective: Aortic dissection and aortic aneurysm rupture are aortic emergencies and their clinical outcomes have improved over the past two decades; however, whether this has translated into lower mortality across countries remains an open question. The purpose of this study was to compare mortality trends from aortic dissection and rupture between the UK, Japan, the USA and Canada.

Methods: We analysed the WHO mortality database to determine trends in mortality from aortic dissection and rupture in four countries from 2000 to 2019.

Clinical impact of right ventricular pacing burden in patients with post-transcatheter aortic valve replacement permanent pacemaker implantation.

Aims: Patients who undergo permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement (TAVR) have a worse outcome. The aim of this study was to identify risk factors of worse outcomes in patients with post-TAVR PPM implantation.

Methods And Results: This is a single-centre, retrospective study of consecutive patients who underwent post-TAVR PPM implantation from 11 March 2011 to 9 November 2019.

Cor-Knot Use in SAVR Facilitates Coplanar Angle Adjustment During TAVR.

The Cor-Knot surgical tying device (LSI Solutions) is an automated suture fastener with a titanium-crimpable sleeve that facilitates a fast and secure knot. The device is an alternative to hand tying, minimizing operation time, and its increasing use is anticipated for minimally invasive cardiac surgeries or in patients with small surgical anatomy. As its use expands, the likelihood of encountering this knotting device during structural interventions may increase.

Risk Stratification of New Persistent Left Bundle Branch Block After Transcatheter Aortic Valve Implantation.

Previous studies reported that new-onset persistent left bundle branch block (NOP-LBBB) was related to worse outcomes after transcatheter aortic valve implantation (TAVI). However, these results can be confounded by the presence of permanent pacemaker (PPM) implantation before and after TAVI. Long-term outcomes and the risk stratification of NOP-LBBB not having PPM implantation before and after TAVI have not been fully investigated.

Outcomes of great vessel debranching to facilitate thoracic endovascular aortic repair.

Objective: With the expanding application of endovascular technology, the need to deploy into zone 0 has been encountered on occasion. In the present study, we evaluated the outcomes of great vessel debranching (GVD) as a method of extending the proximal landing zone to facilitate thoracic endovascular aortic repair (TEVAR).

Methods: We performed a single-center retrospective review of all patients who had undergone GVD followed by TEVAR between May 2013 and December 2020.
