- OBJECTIVES: Degenerative mitral valve disease is the most common indication for mitral valve repair in the Western world. The aim of this study was to study the long term outcome of mitral valve repair for degenerative mitral valve regurgitation in Iceland. MATERIAL AND METHODS: A retrospective study of 101 consecutive mitral valve repair patients (average age 57.7 years, 80.2% male) operated in Iceland 2004-2018 for degenerative mitral valve regurgitation. Long term survival and MACCE (major adverse cardiac and cerebrovascular event) free survival was estimated using the Kaplan-Meier method and compared to age and gender matched reference population. Median follow-up time was 83 months. RESULTS: On average there were 6,7 (range 1-14) mitral valve repairs performed annually with 99% of the patients receiving ring annuloplasty. A total of 82 (82,2%) underwent resection of the posterior leaflet and 64.4% recieved Gore-TexR-chordae. Major early complications occured in 28.7% of cases, most commonly perioperative myocardial infarction (11.9%) and reoperation for bleeding (8.9%). Mortality within 30 days was 2%, the median duration of intensive care unit stay was one day and the median hospital length of stay was 8 days. One patient needed reoperation later for recurrent mitral regurgitation. Five and ten year MACCEfree survival was 91.1% (95%-CI: 85.3-97.2) and 81.0 (95%-CI: 71.6-91.6), respectively. Five year survival was 93.5% (95-CI: 88.6-98.7) and 10 year survival 85.3% (95%-CI: 76.6-94.9), which was not different from an age and gender matched reference population (p=0.135, log-rank test). CONCLUSION: Outcomes of mitral valve repair due to degenerative mitral regurgitation is good in Iceland and results are comparable to larger institutions overseas. Long term prognosis is generally good although early postoperative complications often occur.

- 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. Information was gathered from medical records, including pre-and postoperative results of echocardiography and complications. Overall survival was estimated (Kaplan-Meier) and logistic regression used to identify predictors of operative mortality. The median follow-up time was 8.8 years (0-16.5 years).Results: Of the 428 patients, 151 were female (35.3%), that were on average 2 years older than men (72.6 ± 9.4 vs. 70.4 ± 9.8 yrs., p=0.020). Preoperative symptoms were similar, but women had significantly higher EurosSCORE II than men (5.2 ± 8.8 vs. 3.2 ± 4.6, p=0.002). Maximal pressure-gradient across the aortic valve was higher for women (74.4 ± 29.3 mmHg vs. 68.0 ± 23.4 mmHg, p=0,013) but postoperative complications, operative mortality (8.6% vs. 4.0%, p=0.068) and 5-year survival (78.6% vs. 83.1%, p=0.245) were comparable for women and men. Logistic regression analysis showed that female gender was not an independent predictor of 30-day mortality (OR 1.54, 95% CI 0.63-3.77).Conclusions: Females constitute one third of patients that undergo AVR for AS in Iceland. At the time of surgery females are two years older than men and appear to have a more significant aortic stenosis at the time of surgery. However, complication rates, operative mortality and long-term survival were comparable for both genders.

- Objectives: We studied the incidence and risk factors of reoperation for bleeding following CABG in a nationwide cohort with focus on long-term complications and survival.Design: A retrospective study on 2060 consecutive, isolated CABG patients operated 2001-2016. Outcome of reoperated patients (n = 130) were compared to non-reoperated ones (n = 1930), including major adverse cardiac and cerebrovascular events (MACCE) and overall survival. Risk factors for reoperation were determined using multivariate logistic regression and a Cox proportional hazards model to assess prognostic factors of long-term survival. Median follow-up was 7.6 years.Results: One hundred thirty patients (6.3%) were reoperated with an annual decrease of 4.1% per year over the study period (p=.04). Major complications (18.5 vs. 9.6%) and 30-day mortality (8.5 vs. 1.9%,) were higher in the reoperation group (p<.001). The use of clopidogrel preoperatively (OR 3.62, 95% CI: 1.90-6.57) and reduced left ventricular ejection fraction (OR 2.23, 95% CI: 1.25-3.77) were the strongest predictors of reoperation, whereas off-pump surgery was associated with a lower reoperation risk (OR 0.44, 95% CI: 0.22-0.85). After exluding patients that died within 30 days postoperatively, no difference in long-term survival or freedom from MACCE was found between groups, and reoperation was not an independent risk factor for long-term mortality in multivariate analysis.Conclusions: The reoperation rate in this study was relatively high but decreased significantly over time. Reoperation was associated with twofold increased risk for major complications and fourfold 30-day mortality, but comparable long-term MACCE and survival rates. This implies that if patients survive the first 30 days following reoperation, their long-term outcome is comparable to non-reoperated patients.

- Background: Perioperative management in autologous breast reconstruction has gained focus in recent years. This study compares two pain management protocols in patients undergoing abdominal-based free flap breast reconstruction: a past protocol (PP) and a current protocol (CP)-both intended to reduce opioid consumption postoperatively. The PP entails use of a pain catheter in the abdominal wound and the CP consists of an intraoperative nerve block in addition to refinements in the oral pain management. We hypothesize that the CP reduces opioid consumption compared to PP.Methods: From December 2017 to January 2020, 102 patients underwent breast reconstruction with an abdominal-based free flap. Two postoperative pain management strategies were used during the period; from December 2017 to September 2018, the PP was used which entailed the use of a pain catheter with ropivacaine applied in the abdominal wound with continuous distribution postoperatively in addition to paracetamol orally and oxycodone orally pro re nata (PRN). From October 2018 to January 2020, the CP was used. This protocol included a combination of intraoperative subfascial nerve block and a postoperative oral pain management regime that consisted of paracetamol, celecoxib, and gabapentin as well as oxycodone PRN.Results: The CP group ( n = 63) had lower opioid consumption compared to the PP group ( n = 39) when examining all aspects of opioid consumption, including daily opioid usage in morphine milligram equivalents and total opioid usage during the stay ( p < 0.001). The CP group had shorter length of hospital stay (LOS).Conclusion: Introduction of the CP reduced opioid use and LOS was shorter.
