    Abstract Objective: Myocardial management during on-pump coronary artery bypass grafting (CABG) surgery includes aortic cross-clamping followed by fibrillation (XCF) and aortic cross-clamping followed by diastolic cardioplegia (cardioplegia). The authors wished to compare in-hospital and survival outcomes between these procedures.
    Design: A retrospective observational study utilizing propensity matching.
    Setting: Tertiary Referral Centre for Heart Surgery.
    Participants: A total of 8,875 consecutive patients undergoing CABG surgery between August 1999 and February 2018.
    Interventions: After 1:1 matching, the authors had 3,340 patients in the cardioplegia group and 3,340 in the XCF group.
    Measurements and main results: Baseline characteristics were not significant between the matched cardioplegia and XCF groups. The XCF group had shorter pump times (61.8 minutes +/-26.8 v 74.7 minutes +/-29.5, p < 0.0001) and shorter cross-clamp times (27.80 minutes +/-10.5 v 44.44 minutes +/-18.0, p < 0.0001) compared with the cardioplegia group despite a similar median number of distal anastomoses (3 v 3, p = 0.08). After surgery, atrial arrhythmias (32% v 36%, p = 0.01) and inotropic requirement (25% v 28%, p = 0.006) were less in the XCF group compared with the cardioplegia group, respectively. Other postoperative outcomes (such as mortality and cerebrovascular events) were not statistically different. There was a mean survival advantage in using cardioplegia compared with XCF (15.4 years versus 14.7 years, log-rank, p = 0.014; 10-year survival 64% v 61% and 18-year survival 38% v 34%).
    Conclusion: This is the largest analysis of XCF. XCF does not adversely affect in-hospital outcomes. Long-term results demonstrate cardioplegic arrest may convey a survival advantage that would preclude routine XCF in the modern era.

    Abstract Objectives: The aim of this study was to assess variations in surgical stage distribution in 2 centres within the same UK region. One centre was covered by an active screening program started in November 2018 and the other was not covered by screening.
    Methods: Retrospective analysis of 1895 patients undergoing lung resections (2018-2022) in 2 centres. Temporal distribution was tested using Chi-squared for trends. A lowess curve was used to plot the proportion of stage 1A patients amongst those operated over the years.
    Results: The surgical populations in the 2 centres were similar. In the screening unit (SU), we observed a 18% increase in the proportion of patients with clinical stage IA in the recent phase compared to the early phase (59% vs 50%, P = 0.004), whilst this increase was not seen in the unit without screening. This difference was attributable to an increase of cT1aN0 patients in the SU (16% vs 11%, P = 0.035) which was not observed in the other unit (10% vs 8.2%, P = 0.41). In the SU, there was also a three-fold increase in the proportion of sublobar resections performed in the recent phase compared to the early one (35% vs 12%, P < 0.001). This finding was not evident in the unit without screening.
    Conclusions: Lung cancer screening is associated with a higher proportion of lung cancers being detected at an earlier stage with a consequent increased practice of sublobar resections.

    Abstract Background: Study objectives were to (1) report the clinical profile of and outcome for patients who experience a cardiorespiratory arrest after coronary artery bypass grafting or aortic valve replacement, and (2) identify factors associated with improved probability of survival.
    Methods: We identified 108 consecutive patients who had cardiorespiratory arrest after coronary artery bypass grafting or aortic valve replacement between April 1999 and June 2008. We studied the characteristics of arrests and survivors, and performed a multivariate logistic analysis to determine features associated with survival to hospital discharge.
    Results: Cardiac arrest (n = 86) was more common than respiratory arrest (n = 13; unknown cause, n = 9). Cardiorespiratory arrest occurred with decreasing frequency from the day of surgery. Ventricular fibrillation or tachycardia was the dominant mechanism of cardiac arrest (70% versus 17% for asystole versus 13% for pulseless electrical activity), and the principal causes were postoperative myocardial infarction (n = 46; 53%) and tamponade or bleeding (n = 21; 24%). Resternotomy was performed in 45 patients (52%), cardiopulmonary bypass reinstituted in 14 (16%), and additional grafts constructed in 5 (6%). The causes of respiratory arrest were mainly pulmonary (n = 8) and neurologic (n = 5). Survival to hospital discharge was better for respiratory arrest (69%) than for cardiac arrest (50%). Older age, ejection fraction less than 0.30, and postoperative myocardial infarction decreased the probability of survival.
    Conclusions: Ventricular fibrillation or tachycardia was the most common mechanism, and myocardial infarction, the predominant precipitating cause of cardiac arrest after coronary artery bypass grafting or aortic valve replacement. Despite aggressive resuscitation, outcome is poor. Young patients with good left ventricular function had a better probability of survival if they did not suffer a postoperative myocardial infarction.

    Abstract Objectives: With an ageing population, increasing numbers of octogenarians are undergoing high-risk cardiac surgery. We examine the changing characteristics and in-hospital outcomes for octogenarians over an 18-year period.
    Methods: Clinical data from our prospective database for all octogenarians who had cardiac surgery from March 1999 through May 2016 were reviewed. We examined trends, risk profiles and in-hospital outcomes over 3 eras, namely early (1999-2004), middle (2005-2010) and late (2011-2016). A multivariable analysis was performed to identify independent predictors for adverse outcomes.
    Results: There were 1022 patients aged 80-94 years in our study cohort. The octogenarian population increased progressively from early to late eras (4.5%, n = 255 vs 7.1%, n = 321 vs 9.3%, n = 446), as the average logistic EuroSCORE predicted mortality (9% vs 9.7% vs 10.1%, P < 0.01). On the contrary, observed mortality declined substantially (9.4% vs 7.8% vs 4.7%, P = 0.04) over this period. While cardiac morbidity and respiratory comorbidities were more prevalent in the late era, chronic renal failure was more frequent in the early era. Over time, more procedures were performed electively (P = 0.05). Common operations across all eras were coronary artery bypass grafting (CABG), aortic valve replacement and CABG + aortic valve replacement. Emergency operation [odds ratio (OR) 4.96, 95% confidence interval (CI) 1.51-16.35; P < 0.01], poor ejection fraction (OR 3.38, 95% CI 1.80-6.32; P < 0.01) and bypass time (OR 1.01, 95% CI 1.00-1.02; P < 0.01) were predictors of in-hospital mortality. The late era of surgery (OR 0.41, 95% CI 0.23-0.73; P < 0.01) was associated with reduced mortality risk.
    Conclusions: The operative outcome in this growing surgical population is steadily improving despite the increasing prevalence of comorbidities, and surgery should be performed electively as much as possible.

    Abstract Background: Surgery is the most important therapeutic modality for lung cancer. Surgical outcomes are normally reported as 30-day or 90-day mortality or 5-year survival; 10-year survival is rarely mentioned in national data or international studies.
    Methods: Three hundred and six patients (79% male) underwent pneumonectomy, mainly for lung cancer, from January 1998 to February 2013. Their short- and long-term outcomes up to September 2014 were analyzed retrospectively. The mean age was 64 years (range 22-82 years) and 24% were aged ≥70 years. Thoracoscore was used to calculate the risk of hospital mortality.
    Results: Operative mortality was 4.5% whereas predicted mortality was 8%. The operative mortality for cancer patients was 3.3%; the national mortality for lung cancer is 6.5%. Only 2 patients died in hospital after a pneumonectomy in the last 5 years. Half of the patients who died in hospital were ≥70 years old; 29% (4 patients) died after urgent operations for nonmalignant disease. Overall 5- and 10-year survival was 32% and 20%. Median and mean survival was 26 and 57 months, respectively. Long-term survival was better in females aged <70 years, in left pneumonectomy patients, and in those with squamous cell lung cancer.
    Conclusion: Our mortality for pneumonectomy was 50% less than the national mortality rate and significantly lower than that predicted by the Thoracoscore for lung cancer. This confirms that pneumonectomy is still an effective modality for the treatment of lung cancer, with low operative mortality and good long-term survival, especially in younger patients.
