[Perioperative stroke after aortic valve replacement for aortic stenosis - incidence, risk factors and short-term outcome].

Introduction: One of the most serious complications of surgical aortic valve replacement (SAVR) is stroke that can result in increased rates of complications, morbidity and mortality postoperatively. The aim of this study was to investigate incidence, risk factors and short-term outcome in a well defined cohort of SAVR-patients.

Materials And Method: A retrospective study on 740 consecutive aortic stenosis patients who underwent SAVR in Iceland 2002-2019.

[Incidence and outcomes of perioperative myocardial infarction associated with coronary artery bypass surgery].

Introduction: Perioperative myocardial infarction (PMI) after CABG can contribute to in-hospital morbidity and mortality, however, its clinical significance on long-term outcome, remains inadequately addressed. We studied both 30-day mortality and long-term effects of PMI in Icelandic CABG-patients.

Materials And Methods: A retrospective nationwide-study on 1446 consecutive CABG-patients operated at Landspitali in Iceland 2002-2018 without evidence of preoperative myocardial infarction.

[The effect of obesity on the outcome of surgical aortic valve replacement for aortic stenosis].

Introduction: Our objective was to investigate the effect of obesity on short-term complications and long-term survival after surgical aortic valve replacement (SAVR) for aortic stenosis (AS).

Material And Methods: A retrospective study on 748 patients who underwent SAVR for AS in Iceland 2003-2020. Patients were divided into groups based on body mass index (BMI): normal (18.

[Incidence and predictors of prolonged intensive care unit stay after coronary artery bypass in Iceland].

Introduction: To maximize the use of intensive care unit (ICU) re--sources, it is important to estimate the prevalence and risk factors for prolonged ICU unit stay after coronary artery bypass grafting (CABG) surgery.

Material And Methods: This retrospective cohort study included all patients who underwent primary isolated CABG at Landspitali between 2001 and 2018. Patient information was collected from hospital charts and death registries.

[The use of Intra Aortic Balloon Pump in Coronary Artery Bypass Graft Surgery].

Introduction: Intra-aortic balloon pump (IABP) is a mechanical device that increases cardiac output by increasing diastolic blood flow to the coronary arteries and lowers the afterload of the left ventricle in systole. IABP is primarily used in acute heart failure, that includes patients that have to undergo coronary artery bypass grafting (CABG). Its usage, however, in cardiac surgery has been declining with ongoing controversy regarding its benefits.
