Background: Sutureless-surgical aortic valve replacement (SU-SAVR) has been proposed as a surgical alternative for treating aortic stenosis, which facilitates a minimally invasive approach. While some studies have compared the early outcomes of SU-SAVR versus transcatheter aortic valve replacement (TAVR), most data were obtained in high-risk patients and/or limited to in-hospital outcomes. This study aimed to compare in-hospital and midterm clinical outcomes following SU-SAVR and TAVR in low-risk patients with aortic stenosis. Methods: A total of 806 consecutive low-risk (EuroSCORE II <4%) patients underwent TAVR or SU-SAVR between 2011 and 2020 in 2 centers. A 1:1 propensity score matching was performed and identified 171 pairs with similar characteristics that were included in the analysis. Baseline characteristics, in-hospital and follow-up events (defined according to Valve Academic Research Consortium-2) were collected. Results: Baseline characteristics were well balanced between groups, with a median EuroSCORE II of 1.9% (1.3%–2.5%) in both SU-SAVR and TAVR groups ( P =0.85). There were no statistically significant differences regarding in-hospital mortality (SU-SAVR: 4.1%, TAVR: 1.8%, P =0.199) and stroke (SU-SAVR: 2.3%, TAVR: 2.9%, P =0.736), but SU-SAVR recipients exhibited higher rates of bleeding and new-onset atrial fibrillation, higher residual transvalvular gradients ( P <0.001), and a lower rate of pacemaker implantation ( P =0.011). After a median follow-up of 2 (1–3) years, there were no differences between groups in all-cause mortality (hazard ratio, 0.97 [95% CI, 0.52–1.82], P =0.936) and stroke (hazard ratio, 0.83 [95% CI, 0.32–2.15], P =0.708), but SU-SAVR was associated with a higher risk of heart failure hospitalization (hazard ratio, 5.38 [95% CI, 1.88–15.38], P =0.002). Conclusions: In low-risk patients with aortic stenosis, TAVR was associated with improved in-hospital outcomes (except for conduction disturbances) and valve hemodynamics, compared with SU-SAVR. Although similar mortality and stroke rates were observed at 2-year follow-up, the risk of heart failure hospitalization was higher among SU-SAVR patients. These results may contribute to reinforce TAVR over SU-SAVR for the majority of such patients.
OBJECTIVES Obesity may increase the risk of vascular complications in transfemoral (TF) transcatheter aortic valve replacement (TAVR) procedures. The transcarotid (TC) approach has recently emerged as an alternative access in TAVR. We sought to compare vascular complications and early clinical outcomes in obese patients undergoing TAVR either by TF or TC vascular access. METHODS Multicentre registry including obese patients undergoing TF- or TC-TAVR in 15 tertiary centres. All patients received newer-generation transcatheter heart valves. For patients exhibiting unfavourable ileo-femoral anatomic characteristics, the TC approach was favoured in 3 centres with experience with it. A propensity score analysis was performed for overcoming unbalanced baseline covariates. The primary end point was the occurrence of in-hospital vascular complications (Valve Academic Research Consortium-2 criteria). RESULTS A total of 539 patients were included, 454 (84.2%) and 85 (15.8%) had a TF and TC access, respectively. In the propensity-adjusted cohort (TF: 442 patients; TC: 85 patients), both baseline and procedural valve-related characteristics were well-balanced between groups. A significant decrease in vascular complications was observed in the TC group (3.5% vs 12% in the TF group, odds ratio: 0.26, 95% CI: 0.07–0.95, P = 0.037). There were no statistically significant differences between groups regarding in-hospital mortality (TC: 2.8%, TF: 1.5%), stroke (TC: 1.2%, TF: 0.4%) and life-threatening/major bleeding events (TC: 2.8%, TF: 3.8%). CONCLUSIONS In patients with obesity undergoing TAVR with newer-generation devices, the TC access was associated with a lower rate of vascular complications. Larger randomized studies are warranted to further assess the better approach for TAVR in obese patients.
Introduction: Mortality caused by ST elevation myocardial infarction (STEMI) has declined because of greater use of primary percutaneous coronary intervention (PCI). It is unknown if patients >75 have similar survival as peers. We aim to know it stratifying by sex and assessing how the sex may impact the survival. Methods: We retrospectively selected all patients >75 who suffered a STEMI treated with primary PCI at our institution. We compared their survival with that of the reference population (general population matched by age, sex, and geographical region). A Cox-regression analysis controlling for clinical factors was performed to know if sex was a risk factor. Results: Total of 450 patients were studied. Survival at 1, 3, and 5 years of follow-up for patients who survived the first 30 days was 91.22% (CI95% 87.80–93.72), 79.71% (CI95% 74.58–83.92), and 68.02% (CI95% 60.66–74.3), whereas in the reference population it was 93.11%, 79.10%, and 65.01%, respectively. Sex was not a risk factor, Hazard Ratio = 1.02 (CI95% 0.67-1.53; p = 0.92). Conclusions: Life expectancy of patients suffering a STEMI is nowadays intimately linked to survival in the first 30 days. After one year, the risk of death for both men and women seems similar to that of the general population.
Background: The main randomized trials evaluating patent foramen ovale (PFO) closure after a presumed PFO-associated stroke excluded patients older than 60 years. We aimed to evaluate the early- and long-term clinical outcomes of transcatheter PFO closure in older (>60 years) patients with a cryptogenic ischemic event. Methods: This is a multicenter study including consecutive patients older than 60 years (mean age, 67±5 years) who had a PFO closure following a presumed PFO-related ischemic event. Patients ≤60 years old (mean age, 44±10 years) served as the control group. The primary end point was the occurrence of stroke, transient ischemic attack, or peripheral embolism over the follow-up period. New-onset atrial fibrillation was a secondary end point. Results: A total of 388 and 883 patients >60 and ≤60 years old were included, respectively. Procedural success rate was high (99.9%), and procedural-related complications low (<2%) in both groups. After a median follow-up of 3 (1–8) years, older patients exhibited an incidence of stroke/transient ischemic attack/peripheral embolism of 1.6 events per 100 patient-years (stroke: 0.6 events per 100 patient-years), lower than that expected according to the risk of paradoxical embolism score (observed-to-expected ratio, 0.31 [95% CI, 0.11–0.91]). However, the event rate in older patients was higher than that observed in their younger counterparts (incidence rate ratio, 4.7 [95% CI, 2.36–9.8]). De novo atrial fibrillation after the procedure was more frequent in older patients (2.66 per 100 patient-years versus 0.49 per 100 patient-years, P <0.001). Conclusions: In patients older than 60 years with a presumed PFO-related ischemic event, PFO closure was safe and associated with a relatively low incidence of recurrent ischemic events after a median follow-up of 3 years compared with historical cohorts of patients who did not undergo PFO closure. However, a higher risk of recurrent cerebrovascular events was observed in older patients compared to their younger counterparts. Randomized trials are warranted in this population.
