Background: Recent reports on sex differences in long-term outcomes after surgery for acute type A aortic dissection (ATAAD) are conflicting. We aimed to aggregate updated data on long-term survival and reoperation stratified by sex. Methods: A literature search was conducted using Medline, Embase, and Cochrane Central. Studies reporting sex-stratified long-term survival and/or reoperation following surgery for ATAAD between January 1, 2000, to March 15, 2023 were included. Preoperative characteristics, intraoperative variables, and early perioperative outcomes were meta-analyzed using a random effects model and pooled risk ratio (RR) with men as the reference group. Individual patient-level data for long-term outcomes was reconstructed to generate sex-specific pooled Kaplan-Meier curves to assess long-term survival and freedom from reoperation. Results: A total of 15 studies with 7,608 male and 3,989 female patients were included in this analysis. Female patients were older, had higher rates of hypertension, and had less previous cardiac surgery. Intraoperatively, women received less extensive repairs with lower rates of aortic valve replacement and total arch replacement, and higher rates of hemiarch replacement. There were no sex differences for in-hospital/30-day mortality [risk ratio (RR), 1.18; 95% confidence interval (CI): 0.96, 1.45; P=0.12], stroke (RR, 1.07; 95% CI: 0.90, 1.28; P=0.46), and early reoperation (RR, 0.90; 95% CI: 0.75, 1.09; P=0.28). Female patients had lower long-term survival overall (P<0.001) and amongst survivors at 1-year (P=0.014). Overall survival at 5-year was 82.4% in men and 78.1% in women, and at 10-year was 68.1% for men and 63.4% in women. Male patients had higher rates of long-term reoperation (P<0.001). Freedom for reoperation at 5-year was 88.4% in men vs. 93.1% in women. Conclusions: Though perioperative early outcomes have equalized between the sexes following surgery for ATAAD, differences remain in long-term survival and reoperation.
RESUMEN
BACKGROUND: Randomized trials have compared percutaneous coronary intervention and coronary artery bypass grafting (CABG) in patients with left main coronary artery disease undergoing nonemergent revascularization. However, there is a paucity of real-world contemporary observational studies comparing percutaneous coronary intervention (PCI) and CABG. OBJECTIVES: The purpose of this study was to compare the long-term clinical outcomes of CABG versus PCI in patients with left main coronary disease. METHODS: Clinical and administrative databases for Ontario, Canada, were linked to obtain records of all patients with angiographic evidence of left main coronary artery disease (≥50% stenosis) treated with either isolated CABG or PCI from 2008 to 2020. Emergent, cardiogenic shock, and ST-segment elevation myocardial infarction patients were excluded. Baseline characteristics of patients were compared and 1:1 propensity score matching was performed. Late mortality and major adverse cardiac and cerebrovascular events were compared between the matched groups using a Cox proportional hazard model. RESULTS: After exclusions, 1,299 and 21,287 patients underwent PCI and CABG, respectively. Prior to matching, PCI patients were older (age 75.2 vs 68.0 years) and more likely to be women (34.6% vs 20.1%), although they had less CAD burden. Propensity score matching on 25 baseline covariates yielded 1,128 well-matched pairs. There was no difference in early mortality between PCI and CABG (5.5% vs 3.9%; P = 0.075). Over 7-year follow-up, all-cause mortality (53.6% vs 35.2%; HR: 1.63; 95% CI: 1.42-1.87; P < 0.001) and major adverse cardiac and cerebrovascular events (66.8% vs 48.6%; HR: 1.77; 95% CI: 1.57-2.00) were significantly higher with PCI than CABG. CONCLUSIONS: CABG was the most common revascularization strategy in this real-world registry. Patients undergoing PCI were much older and of higher risk at baseline. After matching, there was no difference in early mortality but improved late survival and freedom from major adverse cardiac and cerebrovascular events with CABG.

OBJECTIVE: We sought to compare the long-term outcomes of multiarterial graft (MAG) coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) with second-generation drug-eluting stents (DES) to treat stable multivessel coronary artery disease. METHODS: This study was a multicenter population-based retrospective analysis of all residents of Ontario, Canada, from January 1, 2011, to December 31, 2019. We identified 3600 cases of elective primary isolated CABG with MAG and 2187 cases of PCI with second-generation DES. RESULTS: After the application of propensity score-weighting using overlap weights, MAG was associated with better survival over 5 years compared with DES (96.8% vs 94.5%; hazard ratio [HR], 0.56; 95% CI, 0.37-0.85). MAG was also associated with better secondary outcomes including a composite of death, myocardial infarction, and stroke (94.3% vs 88.5%; HR, 0.49; 95% CI, 0.36-0.65). The rate of death, stroke, myocardial infarction, and repeat revascularization (91.2% vs 70.7%; HR, 0.24; 95% CI, 0.20-0.30), and the individual end points of myocardial infarction (1.4% vs 6.9%; HR, 0.22; 95% CI, 0.13-0.35), and repeat revascularization (4.1% vs 24.2%; HR, 0.14; 95% CI, 0.10-0.18) were lower with MAG. PCI with second-generation DES was associated with a lower rate of stroke up to 5 years (0.6% vs 1.8%; HR, 3.97; 95% CI, 1.45-10.88). CONCLUSIONS: CABG with MAG was associated with better survival and fewer major cardiac adverse events compared with second-generation DES and might be considered the treatment of choice for patients with stable multivessel coronary artery disease. Further randomized controlled trials are needed to confirm this hypothesis.

Background The degree of hospital-level variation in the ratio of percutaneous coronary interventions to coronary artery bypass grafting procedures (PCI:CABG) and the association of the PCI:CABG ratio with clinical outcome are unknown. Methods and Results In a multicenter population-based study conducted in Ontario, Canada, we identified 44 288 patients from 19 institutions who had nonemergent diagnostic angiograms indicating severe multivessel coronary artery disease (2013-2017) and underwent a coronary revascularization procedure within 90 days. Hospitals were divided into tertiles according to their adjusted PCI:CABG ratio into low (0.70-0.85, n=17 487), medium (1.01-1.17, n=15 275), and high (1.18-1.29, n=11 526) ratio institutions. Compared with low PCI:CABG ratio hospitals, hazard ratios (HRs) for major adverse cardiac and cerebrovascular events were higher at medium (HR, 1.19; 95% CI, 1.14-1.25) and high ratio (HR, 1.21; 95% CI, 1.15-1.27) hospitals during a median 3.3 (interquartile range 2.1-4.6) years follow-up. When interventional cardiologists performed the diagnostic angiogram, the odds of the patient receiving PCI was higher (odds ratio, 1.37; 95% CI, 1.23-1.52) than when it was performed by noninterventional cardiologists, after accounting for patient characteristics. Having the diagnostic angiogram at an institution without cardiac surgical capabilities was independently associated with a higher risk of major adverse cardiac and cerebrovascular events (HR, 1.07; 95% CI, 1.02-1.11), death (HR, 1.09; 95% CI, 1.02-1.18), and myocardial infarction (HR, 1.10; 95% CI, 1.03-1.17). Conclusions Patients undergoing diagnostic angiography in hospitals with higher PCI:CABG ratio had higher rates of adverse outcomes, including major adverse cardiac and cerebrovascular events, myocardial infarction, and repeat revascularization. Presence of on-site cardiac surgery was associated with better survival and lower major adverse cardiac and cerebrovascular events.

OBJECTIVE: We sought to determine the risk factors associated with late mortality or complications (thoracoabdominal aortic aneurysm [TAAA] life-altering events [TALE]: a composite of mortality, permanent paraplegia, permanent dialysis, and stroke) for patients who had undergone endovascular or open TAAA repair. METHODS: We performed a population-based study of patients who had undergone TAAA repair in Ontario, Canada, from 2006 to 2017. The association of baseline risk factors with mortality and complications after repair was examined using Cox hazards models with hospital-specific random effects. The survival of patients who had undergone TAAA repair was compared with that of controls without TAAAs. The two groups were matched by age, sex, area of residence, and average annual household income. The type of repair (endovascular vs open) was included in all models. RESULTS: We identified 664 adults (mean age, 69.3 ± 10.6 years; 71% men) who had undergone TAAA repair. At 5 and 8 years, survival was 55.0% (95% confidence interval [CI], 49.8%-60.1%) and 44.6% (95% CI, 40.4%-49.6%) for patients who had undergone TAAA repair vs 85.6% (95% CI, 83.9%-87.1%) and 76.3% (95% CI, 73.8%-78.8%) for the control population, respectively (hazard ratio [HR], 1.97; 95% CI, 1.67-2.32; P < .01). For the TAAA group, freedom from TALE was 49.2% (95% CI, 44.7%-53.7%) and 37.3% (95% CI, 33.1%-42.4%) at 5 and 8 years of follow-up, respectively. On multivariable analysis, the risk factors associated with mortality during follow-up included older age (HR, 1.21 per 5-year increase; 95% CI, 1.13-1.28), peripheral artery disease (HR, 1.46; 95% CI, 1.03-2.09), hypertension (HR, 1.58; 95% CI, 1.03-2.43), congestive heart failure (HR, 1.78; 95% CI, 1.34-2.36), and urgent procedures (HR, 2.27; 95% CI, 1.74-3.00). A lower rate of death was observed for those with previous coronary revascularization (HR, 0.63; 95% CI, 0.41-0.96) and those who had undergone repair at high-volume institutions (>60 TAAA repairs during the study period; HR, 0.71; 95% CI, 0.55-0.91). Older age, chronic kidney disease, congestive heart failure, and urgent procedures were associated with a higher rate of TALE. The type of repair (endovascular vs open) was not associated with mortality or TALE. CONCLUSIONS: TAAA repair was associated with reduced long-term survival compared with the general population, regardless of the mode of treatment. Urgent or emergent repair was the most profound risk factor for late adverse events. The type of repair (endovascular vs open) was not a predictor of long-term death or complications. Previous coronary revascularization and treatment performed at a high-volume institution were associated with improved late outcomes for patients undergoing TAAA repair.

OBJECTIVE: We sought to determine the early and late outcomes of endovascular versus open thoracoabdominal aortic aneurysm repair. METHODS: We performed a multicenter population-based study across the province of Ontario, Canada, from 2006 to 2017. The primary end point was mortality. Secondary end points were time to first event of a composite of mortality, permanent spinal cord injury, permanent dialysis, and stroke, the individual end points of the composite, patient disposition at discharge, hospital length of stay, myocardial infarction, and secondary procedures at follow-up. RESULTS: A total of 664 adults undergoing surgical repair of a thoracoabdominal aortic aneurysm (endovascular: n = 303 [45.5%] vs open: n = 361 [54.5%]) were identified using an algorithm of administrative codes validated against the operative records. Propensity score matching resulted in 241 patient pairs. Endovascular repairs increased during the study and currently comprise more than 50% of total repairs. In the matched sample, open repair was associated with a higher incidence of in-hospital death (17.4% vs 10.8%, P = .04), complications (26.1% vs 17.4%, P = .02), discharge to rehabilitation facilities (18.7% vs 10.0%, P = .02), and longer length of stay (12 [7-21] vs 6 [3-13] days, P < .01). Long-term mortality was not significantly different (hazard ratio, 1.09; 95% confidence interval, 0.78-1.50), nor were the other secondary end points, with the exception of secondary procedures, which were higher in the endovascular group (hazard ratio, 2.64; 95% confidence interval, 1.54-4.55). At 8 years, overall survival was 41.3% versus 44.6% after endovascular and open repair (P = .62). CONCLUSIONS: Endovascular repair was associated with improved early outcomes but higher rates of secondary procedures after discharge. Long-term survival after thoracoabdominal aortic aneurysm repair is poor and independent of repair technique.

OBJECTIVE: Multiple arterial grafting (MAG) in coronary artery bypass grafting (CABG) is associated with higher survival and freedom from major adverse cardiac and cerebrovascular events (MACCEs) in observational studies of mostly men. It is not known whether MAG is beneficial in women. Our objectives were to compare the long-term clinical outcomes of MAG versus single arterial grafting (SAG) in women undergoing CABG for multivessel disease. METHODS: Clinical and administrative databases for Ontario, Canada, were linked to obtain all women with angiographic evidence of left main, triple or double vessel disease undergoing isolated non-emergent primary CABG from 2008 to 2019. 1:1 propensity score matching was performed. Late mortality and MACCE (composite of stroke, myocardial infarction, repeat revascularisation and death) were compared between the matched groups with a stratified log-rank test and Cox proportional-hazards model. RESULTS: 2961 and 7954 women underwent CABG with MAG and SAG, respectively, for multivessel disease. Prior to propensity-score matching, compared with SAG, those who underwent MAG were younger (66.0 vs 68.9 years) and had less comorbidities. After propensity-score matching, in 2446 well-matched pairs, there was no significant difference in 30-day mortality (1.6% vs 1.8%, p=0.43) between MAG and SAG. Over a median and maximum follow-up of 5.0 and 11.0 years, respectively, MAG was associated with greater survival (HR 0.85, 95% CI 0.75 to 0.98) and freedom from MACCE (HR 0.85, 95% CI 0.76 to 0.95). CONCLUSIONS: MAG was associated with greater survival and freedom from MACCE and should be considered for women with good life expectancy requiring CABG.

OBJECTIVE: To compare 1-year health care costs between endovascular and open thoracoabdominal aortic aneurysm (TAAA). METHODS: Population-based administrative health databases were used to capture TAAA repairs performed in Ontario, Canada, between January 2006 and February 2017. All health care costs incurred by the Ministry of Health from a single-payer universal health care system were included. Costs of the aortic endografts and ancillary devices for the index procedure were estimated as C$44,000 per endovascular case vs C$1000 for open cases, based on previous reports. Costs (2017 Canadian dollars) were calculated in phases (1, 1-3, 3-6, and 6-12 months from surgery) with censoring for death. For each phase, propensity score matching of endovascular and open cases based on preoperative patient and hospital characteristics was used. The association between preoperative characteristics (including repair approach) and the first month postprocedure cost was characterized through multivariable analysis. RESULTS: Overall 664 TAAA repairs were identified (open, n = 361 [54.5%] and endovascular, n = 303 [45.6%]). At 1 month, the median cost was higher for endovascular TAAA repair in the prematching cohort (C$64,892 vs C$36,647; P < .01). Similarly, in 241 well-balanced endovascular/open patient pairs after propensity score matching, the median health care costs were higher in endovascular TAAA cases during the first month (C$62,802 vs C$33,605; P < .01). The 1- to 3-month median cost was not statistically different between endovascular and open TAAA cases either before matching (C$2781 vs C$2618; P = .71) or after matching (C$2762 vs C$2092; P = .58). Likewise, in the 3- to 6-month and 6- to 12-month postprocedure intervals, there were no significant differences in the median health care costs between groups. On multivariable analysis, older age (5-year increments) (relative change [RC] in mean cost, 1.05; 95% confidence interval [CI], 1.04-1.06; P = .01), urgent procedures (RC, 1.29; 95% CI, 1.10-1.52; P < .01), and history of stroke (RC, 1.34; 95% CI, 1.00-1.78; P = .05) were associated with higher costs in the first postoperative month, whereas open relative to endovascular TAAA repair was associated with a decreased 1-month cost (RC, 0.65; 95% CI, 0.56-0.74; P < .01). CONCLUSIONS: TAAA repair is expensive regardless of technique. Compared with open TAAA repair, endovascular repair was associated with a higher early cost, owing to the upfront cost of the endograft and aortic ancillary devices. There was no difference in cost from 1 to 12 months after repair. A decrease in the cost of endovascular devices might allow equivalent costs between endovascular and open TAAA repair.
