Objectives: Our objective was to examine intermediate-term survival and reinterventions in unselected patients, stratified according to indication, who received a Freestyle (Medtronic Inc, Minneapolis, Minn) bioprosthesis as a full aortic root replacement.
Methods: Data from medical records were retrospectively collected for patients who had aortic root replacement using Freestyle bioprostheses between 1999 and 2018 at 6 North-Atlantic centers. Survival status was extracted from national registries and results stratified according to indication for surgery.
Atrioventricular (AV) node conduction disturbances are common following surgical aortic valve replacement (SAVR), and in some cases the patient needs a permanent pacemaker (PPM) implantation before discharge from hospital. Little is known about the long-term need for PPM and the PPM dependency of these individuals. We determined the incidence of PPM implantation before and after discharge in SAVR patients.

Methods: We included 587 patients who underwent SAVR for AS in Iceland during the period 2002-2016, with a total follow-up of 3245 patient-years. Short-term and long-term outcomes, 30-day mortality, and long-term survival (Kaplan-Meier) were analyzed.
Introduction: Aortic valve replacement (AVR) for aortic stenosis (AS) is the second most common open-heart procedure performed in Iceland. The aim of this study was to analyze the early outcome of AVR among females in Iceland.
Materials And Methods: This was a retrospective study including 428 patients who underwent surgical AVR due to AS in Iceland from 2002-2013.
