A posterior pericardial chest tube is associated with reduced incidence of postoperative atrial fibrillation after cardiac surgery: A propensity score-matched study.

Objective: Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery that is associated with other adverse outcomes. Recent studies have shown that drainage of pericardial effusion by a posterior pericardial incision reduces the incidence of POAF. An alternative approach is a chest tube placed posteriorly in the pericardium.

A mediastinal angiomatoid fibrous histiocytoma radically resected with the use of cardiopulmonary bypass and transection of the ascending aorta.

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumour that rarely behaves malignant. We report a radical resection of a mediastinal angiomatoid fibrous histiocytoma, which grew invasively into the pulmonary artery wall, was adherent to the posterior aorta and close to the main stem of the left coronary artery. A transection of the aorta was performed using cardiopulmonary bypass and cardioplegic arrest for a safe and radical removal that resulted in symptom relief.

Bleeding is associated with severely impaired outcomes in surgery for acute type a aortic dissection.

. Surgery for acute type A aortic dissection confers a risk for significant bleeding. We analyzed the impact of massive bleeding on complications after surgery for acute type A aortic dissection.

An epidemiological and clinicopathological study of type 1 vs. type 2 morphological subtypes of papillary renal cell carcinoma- results from a nation-wide study covering 50 years in Iceland.

Introduction: Papillary renal cell carcinoma (pRCC) is the second most common histology of renal cell carcinoma (RCC), accounting for 10-15% of cases. Traditionally, pRCC is divided into type 1 and type 2, although this division is currently debated as a prognostic factor of survival. Our aim was to investigate the epidemiology and survival of the pRCC subtypes in a whole nation cohort of patients during a 50-year period.

[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.

Methods: A population-based retrospective study on 68 consecutive patients (mean age 58 years, 58.

A successful shift from thoracotomy to video-assisted thoracoscopic lobectomy for non-small cell lung cancer in a low-volume center.

Objectives: Although video-assisted thoracoscopic surgery (VATS) lobectomy has become the gold standard for pulmonary resections of non-small-cell lung cancer (NSCLC), lobectomy is still performed via thoracotomy in many European and North American centres. VATS lobectomy was implemented overnight from thoracotomy in our low-volume centre in early 2019, after 1 senior surgeon undertook observership VATS-training overseas, and immediately became the mainstay of surgical treatment for NSCLC in Iceland. We aimed to investigate our short-term outcomes of VATS lobectomy.

[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.

Associations between new-onset postoperative atrial fibrillation and long-term outcome in patients undergoing surgical aortic valve replacement.

Objectives: Data on prognostic implications of new-onset postoperative atrial fibrillation (POAF) after surgical aortic valve replacement (SAVR) is limited. We sought to explore associations between POAF, early initiated oral anticoagulation (OAC) and long-term outcome after SAVR and combined SAVR + coronary artery bypass grafting (CABG).

Methods: This is a retrospective, population-based study including all isolated SAVR (n = 7038) and combined SAVR and CABG patients (n = 3854) without a history of preoperative atrial fibrillation (AF) in Sweden 2007-2017.

Dual or single antiplatelet therapy after coronary surgery for acute coronary syndrome (TACSI trial): Rationale and design of an investigator-initiated, prospective, multinational, registry-based randomized clinical trial.

The TACSI trial (ClinicalTrials.gov Identifier: NCT03560310) tests the hypothesis that 1-year treatment with dual antiplatelet therapy with acetylsalicylic acid (ASA) and ticagrelor is superior to only ASA after isolated coronary artery bypass grafting (CABG) in patients with acute coronary syndrome. The TACSI trial is an investigator-initiated pragmatic, prospective, multinational, multicenter, open-label, registry-based randomized trial with 1:1 randomization to dual antiplatelet therapy with ASA and ticagrelor or ASA only, in patients undergoing first isolated CABG, with a planned enrollment of 2200 patients at Nordic cardiac surgery centers.

Civilian vascular trauma, treatment and outcome at a level 1-trauma centre.

Background: Outcomes after vascular injuries in wartime are well documented, but studies on vascular injuries in a civilian European populations are scarce.

Methods: A retrospective study on all adults admitted to a North-European level 1-trauma centre 2009-2018 with The Abbreviated Injury Scale-codes for non-iatrogenic vascular trauma (VT). Data were extracted from both national and regional trauma-registries, as well as patient charts.

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.

Material And Methods: A retrospective study on patients receiving heart transplantation from the first procedure in 1988 until March 2019. Clinical information was gathered from Landspitali Transplantation Clinic, patient charts, and information on donated hearts from the Icelandic Donation Registry.

Non-infectious sternal dehiscence after coronary artery bypass surgery.

Introduction: Non-infectious sternal dehiscence (NISD) is a known complication following coronary artery bypass grafting (CABG), with previous studies estimating an incidence of 0.4-1% of surgeries. We aimed to study the incidence of NISD together with short- and long-term outcomes in a whole-nation cohort of patients.

[Management of patients with left main stem stenosis in Iceland 2010-2020: PCI or CABG].

Introduction: Coronary artery bypass surgery (CABG) has been standard treatment for patients with left main coronary artery disease (LMCAD) but percutaneous coronary intervention (PCI) can be a good alternative. Our aim was to evaluate revascularization of LMCAD-patients in Iceland and treatment changes in recent years. We also assessed the impact of patient background factors on treatment choice and long-term survival.

[Management and revascularization of diabetics with coronary artery disease in Iceland].

Background: The incidence of diabetes is growing, and diabetics have increased risk of atherosclerosis and diffuse coronary artery disease (CAD). Our aim was to assess the revascularization treatment of diabetics with CAD in Iceland from 2010-2020, changes in management and long-term survival of patients.

Methods: All patients in Iceland with diabetes and CAD on cardiac catheterization 2010-2020 were included in this retrospective, population-based study.

Utilization and outcomes of tracheostomies in the intensive care unit in Iceland in 2007-2020: A descriptive study.

Background: Tracheostomies are commonly utilized in ICU patients due to prolonged mechanical ventilation, upper airway obstruction, or surgery in the face/neck region. However, practices regarding the timing of placement and utilization vary. This study provides a nationwide overview of tracheostomy utilization and outcomes in the ICU over a 14-year period.

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.

[Short- and long-term outcomes following surgery for primary spontaneous pneumothorax in Iceland].

Background: Primary spontaneous pneumothorax (PSP) is a common disease where surgery is indicated for persistant air leak or recurrent pneumothorax. We studied the outcomes of PSP-surgery over a 28 year period in a whole nation.

Materials And Methods: A retrospective study on 386 patients (median age 24 years, 78% males) that underwent 430 PSP surgeries at Landspitali University Hospital 1991-2018.

Pituitary MRI Features in Acromegaly Resulting From Ectopic GHRH Secretion From a Neuroendocrine Tumor: Analysis of 30 Cases.

Context: Ectopic acromegaly is a consequence of rare neuroendocrine tumors (NETs) that secrete GHRH. This abnormal GHRH secretion drives GH and IGF-1 excess, with a clinical presentation similar to classical pituitary acromegaly. Identifying the underlying cause for the GH hypersecretion in the setting of ectopic GHRH excess is, however, essential for proper management both of acromegaly and the NET.
