RESUMO
INTRODUCTION AND OBJECTIVES: Impact of gender on long-term outcomes after transcatheter aortic valve implantation (TAVI) remains uncertain. We aimed to investigate gender-specific differences in TAVI and its impact on outcomes. METHODS: This analysis used data from the prospective Spanish TAVI registry, which included consecutive TAVI patients treated in 46 Spanish centers from 2009 to 2021. The primary endpoint was all-cause mortality at 12 months. Secondary endpoints included in-hospital and 30-day mortality and TAVI-related complications. Adjusted logistic and Cox regression analyses were performed. RESULTS: The study included 12 253 consecutive TAVI patients with a mean age of 81.2 ± 6.4 years. Women (53.9%) were older, and had a higher STS-PROM score (7.0 ± 7.0 vs 6.2 ± 6.7; P < .001) than men. Overall, the TAVI-related complication rate was similar between women and men, with specific gender-related complications. While women more frequently developed in-hospital vascular complications (13.6% vs 9.8%; P < .001) and cardiac tamponade (1.5% vs 0.6%; P = .009), men showed a higher incidence of permanent pacemaker implantation (14.5% vs 17.4%; P = .009). There was no difference in all-cause mortality either in hospital (3.6% vs 3.6%, adjusted odds ratio [OR], 1.01; 95% confidence interval [95%CI], 0.83-1.23; P = .902), at 30 days (4.2% vs 4.2%, adjusted OR, 0.90; 95%CI, 0.65-1.25; P = .564) or at 1 year (11% vs 13%, adjusted HR, 0.94; [0.80-1.11]; P = .60). CONCLUSIONS: women treated with TAVI are older and have more comorbidities than men, leading to distinct complications between genders. Nevertheless, all-cause mortality in the short-term and at 1-year was similar between men and women.
RESUMO
INTRODUCTION AND OBJECTIVES: Transcatheter edge-to-edge repair (TEER) should be considered in patients with heart failure and secondary mitral regurgitation (MR). Angiotensin receptor-neprilysin inhibitors (ARNIs) have been demonstrated to improve prognosis in heart failure. We aimed to evaluate the impact ARNIs on patient selection and outcomes. METHODS: The population of the Spanish TEER prospective registry (March 2012 to January 2021) was divided into 2 groups: a) TEER before the ARNI era (n=450) and b) TEER after the recommendation of ARNIs by European Guidelines (n=639), with further analysis according to intake (n=52) or not (n=587) of ARNIs. RESULTS: A total of 1089 consecutive patients underwent TEER for secondary MR. In the ARNI era, there was a reduction in left ventricle dilation (82mL vs 100mL, P=.025), and better function (35% vs 38%, P=.011). At 2 years of follow-up, mortality (10.6% vs 17.3%, P <.001) and heart failure readmissions (16.6% vs 27.8%, P <.001) were lower in the ARNI era, but not recurrent MR. In the ARNI era, 1- and 2-year mortality were similar irrespective of ARNI intake but patients on ARNIs had a lower risk of readmission+mortality at 2 years (OR, 0.369; 95%CI, 0.137-0.992; P=.048), better NYHA class, and lower recurrence of MR III-IV (1.9% vs 14.3%, P=.011). CONCLUSIONS: Better patient selection for TEER has been achieved in the last few years with a parallel improvement in outcomes. The use of ARNIs was associated with a significant reduction in overall events, better NYHA class, and lower MR recurrence.

BACKGROUND: Both balloon-expandable (BE) and self-expandable (SE) valves for transcatheter aortic valve implantation (TAVI) are broadly used in clinical practice. However, adequately powered randomized controlled trials comparing these two valve designs are lacking. METHODS: The CENTER-study included 12,381 patients undergoing transfemoral TAVI. Patients undergoing TAVI with a BE-valve (n = 4096) were compared to patients undergoing TAVI with an SE-valve (n = 4096) after propensity score matching. Clinical outcomes including one-year mortality and stroke rates were assessed. RESULTS: In the matched population of n = 5410 patients, the mean age was 81 ± 3 years, 60% was female, and the STS-PROM predicted 30-day mortality was 6.2% (IQR 4.0-12.4). One-year mortality was not different between patients treated with BE- or SE-valves (BE: 16.4% vs. SE: 17.0%, Relative Risk 1.04, 95%CI 0.02-1.21, p = 0.57). One-year stroke rates were also comparable (BE: 4.9% vs. SE: 5.3%, RR 1.09, 95%CI 0.86-1.37, p = 0.48). CONCLUSION: This study suggests that one-year mortality and stroke rates were comparable in patients with severe aortic valve stenosis undergoing TAVI with either BE or SE-valves.
RESUMO
BACKGROUND AND AIM: Recent randomized data comparing percutaneous mitral valve repair (PMVR) versus optimal medical treatment in patients with functional MR (FMR) seemed to highlight the importance of the learning curve not only for procedural outcomes but also for patient selection. The aim of the study was to compare a contemporary series of patients undergoing PMVR using a second-generation Mitraclip device (Mitraclip NT) with previous cohorts treated with a first-generation system. METHODS: This multicenter study collected individual data from 18 centers between 2012 and 2017. The cohort was divided into three groups according to the use of the first-generation Mitraclip during the first (control-1) or second half (control-2) or the Mitraclip NT system. RESULTS: A total of 545 consecutive patients were included in the study. Among all, 182 (33.3%), 183 (33.3%), and 180 (33.3%) patients underwent mitral repair in the control-1, control-2, and NT cohorts, respectively. Procedural success was achieved in 93.3% of patients without differences between groups. Major adverse events did not statistically differ among groups, but there was a higher rate of pericardial effusion in the control-1 group (4.3%, 0.6%, and 2.6%, respectively; p = 0.025). The composite endpoint of death, surgery, and admission for congestive heart failure (CHF) at 12 months was lower in the NT group (23.5% in control-1, 22.5% in control-2, and 8.3% in the NT group; p = 0.032). CONCLUSIONS: The present paper shows that contemporary clinical outcomes of patients undergoing PMVR with the Mitraclip system have improved over time.
RESUMO
BACKGROUND: Isolated atrial fibrillation can cause mitral regurgitation (MR) in patients with normal left ventricular systolic function and no organic disease of the mitral valve. Little information is available regarding outcomes of Mitraclip in patients with atrial functional mitral regurgitation (AFMR). We aimed to evaluate 12-month clinical and echocardiographic outcomes of transcatheter mitral valve repair (TMVR) with MitraClip in patients with AFMR compared to those with ventricular functional or degenerative/mixed MR. METHODS: Registry-based analysis of all consecutive patients who underwent TMVR and were included in the Spanish Registry of Mitraclip. Changes in MR and NYHA functional class, and a combined endpoint including all-cause mortality and hospitalizations due to heart failure were the main outcomes. RESULTS: Overall, 1074 (69.1% male, 73.3 ± 10.2 years-old) patients were analyzed in this report. 48 patients (4.5%) presented AFMR. AFMR was significantly reduced after TMVR, with a procedural success rate of 91.7%, and this reduction persisted at 12-month (p < 0.001). Patients with AFMR showed a significant functional improvement at 6- and 12-month follow-up in our series (baseline: NYHA III 70.8% IV 18.8% vs. 1-year: NYHA III 21.7% IV 0%; p < 0.001). The probability of survival free of readmission for heart failure and all-cause mortality within the first year after TMVR was 74.9%. Procedural and clinical outcomes, as well as recurrent rates of MR were similar acutely and at 1-year compared to other etiologies. CONCLUSION: TMVR in patients with AFMR showed no significant differences compared to ventricular functional or degenerative/mixed MR regarding MR reduction or clinical outcomes.

BACKGROUND: In catheter-based procedures, acute kidney injury (AKI) is a frequent, serious complication ranging from 10% to 30%. In MitraClip (Abbott Vascular, Santa Clara, California), a usually contrast-free procedure, there is scarce data about its real incidence and impact. OBJECTIVES: This study aimed to evaluate incidence, predictive factors, and midterm outcomes of AKI in patients with significant mitral regurgitation (MR) undergoing transcatheter valve repair with MitraClip. METHODS: A total of 721 patients undergoing MitraClip were included. AKI was defined as an absolute or a relative increase in serum creatinine of >0.3 mg/dl or ≥50%, respectively, or the need for hemodialysis during index hospitalization. RESULTS: The mean age of the patients was 72 ± 11 years (28.3% women). Median estimated glomerular filtration rate (eGFR) was 43.7 ml/min/1.73 m2 (interquartile range: 30.9 to 60.1 ml/min/1.73 m2), and was <60 ml/min/1.73 m2 in 74.9% of the patients. AKI after MitraClip occurred in 106 patients (14.7%). Baseline hemoglobin (<11 g/dl) (odds ratio [OR]: 1.97; p = 0.003), urgent procedure (OR: 3.44; p = 0.003), and absence of device success (OR: 3.37; p < 0.001) were independent predictors of AKI. Patients with AKI had worse outcomes compared to those without AKI, including a higher proportion of in-hospital bleeding events (3.8% vs. 0.8%; p = 0.011), 2-year all-cause mortality (40.5% vs. 18.7%; p <0.001), and major adverse cardiac events (63.6% vs. 23.5%; p <0.001). Combination of AKI with significant residual MR after the procedure conferred even worst outcomes (2-year all-cause mortality 50.0% vs. 19.6%; p = 0.001, and major adverse cardiac events 70.0% vs. 18.9%; p < 0.001). CONCLUSIONS: Despite being a "zero-contrast" procedure, one-sixth of patients undergoing transcatheter mitral valve repair had AKI, linked to device failure or other severe conditions. The occurrence of AKI was associated with worse outcomes, highlighting the importance to detect and reduce this complication in high-risk population.

BACKGROUND AND OBJECTIVES: Patients older than 75 years with ST-segment elevation myocardial infarction undergoing primary angioplasty in cardiogenic shock have high mortality. Identification of preprocedural predictors of short- and long-term mortality could be useful to guide decision-making and further interventions. METHODS: We analyzed a nationwide registry of primary angioplasty in the elderly (ESTROFA MI+75) comprising 3576 patients. The characteristics and outcomes of the subgroup of patients in cardiogenic shock were analyzed to identify associated factors and prognostic predictors in order to derive a baseline risk prediction score for 1-year mortality. The score was validated in an independent cohort. RESULTS: A total of 332 patients were included. Baseline independent predictors of mortality were anterior myocardial infarction (HR 2.8, 95%CI, 1.4-6.0 P=.005), ejection fraction<40% (HR 2.3, 95%CI, 1.14-4.50 P=.018), and time from symptom onset to angioplasty >6hours (HR 3.2, 95%CI, 1.6-7.5; P=.001). A score was designed that included these predictive factors (score "6-ANT-40"). Survival at 1 year was 54.5% for patients with score 0, 32.3% for score 1, 27.4% for score 2 and 17% for score 3 (P=.004, c-statistic 0.70). The score was validated in an independent cohort of 124 patients, showing 1-year survival rates of 64.5%, 40.0%, 28.9%, and 22.2%, respectively (P=.008, c-statistic 0.68). CONCLUSIONS: A preprocedural score based on 3 simple clinical variables (anterior location, ejection fraction<40%, and delay time >6 hours) may be used to estimate survival after primary angioplasty in elderly patients with cardiogenic shock and to guide preinterventional decision-making.

BACKGROUND: In elderly patients with ST elevated myocardial infarction (STEMI) and multivessel disease (MVD the outcomes related with different revascularization strategies are not well known. METHODS: Subgroup-analysis of a nation-wide registry of primary angioplasty in the elderly (ESTROFA MI+75) with 3576 patients over 75years old from 31 centers. Patients with MVD were analyzed to describe treatment approaches and 2years outcomes. RESULTS: Of 1830 (51%) with MVD, 847 (46%) underwent multivessel revascularization either in acute (51%), staged (44%) or both procedures (5%). Patients with previous myocardial infarction and those receiving drug-eluting stents or IIb-IIIa inhibitors were more prone to be revascularized, whereas older patients, females and those with Killip III-IV, renal failure and higher ejection fraction were less likely. Survival free of cardiac death and infarction at 2years was better for those undergoing multivessel PCI (85.8% vs. 80.4%, p<0.0008), regardless of Killip class. Multivessel PCI was protective of cardiac death and infarction (HR 0.60, 95% CI 0.40-0.89; p=0.011). Complete revascularization made no difference in outcomes among those patients undergoing multivessel PCI. The best prognosis corresponded to those undergoing multivessel PCI in staged procedures (p<0.001). A propensity score matching analysis (514 patients in each group) yielded similar results. CONCLUSIONS: In elderly patients with STEMI and MVD, multivessel PCI was related with better outcomes especially after staged procedures. Among those undergoing multivessel PCI, anatomically defined completeness of revascularization had not prognostic influence. SUMMARY: We sought to investigate the revascularization strategies applied and their prognostic implications in patients aged over 75years with ST elevated myocardial infarction showing multivessel disease. Of 1830 patients, 847 (46%) underwent multivessel PCI either in acute (51%), staged (44%) or both procedures (5%). Multivessel PCI was independent predictor of cardiac death and infarction with the best prognosis corresponding to those undergoing staged procedures.

INTRODUCTION AND OBJECTIVES: The proportion of elderly patients undergoing primary angioplasty is growing. The present study describes the clinical profile, procedural characteristics, outcomes, and predictors of outcome. METHODS: A 31-center registry of consecutive patients older than 75 years treated with primary angioplasty. Clinical and procedural data were collected, and the patients underwent clinical follow-up. RESULTS: The study included 3576 patients (39.3% women, 48.5% with renal failure, 11.5% in Killip III or IV, and 29.8% with>6hours of chest pain). Multivessel disease was present in 55.4% and nonculprit lesions were additionally treated in 24.8%. Radial access was used in 56.4%, bivalirudin in 11.8%, thromboaspiration in 55.9%, and drug-eluting stents in 26.6%. The 1-month and 2-year incidences of cardiovascular death were 10.1% and 14.7%, respectively. The 2-year rates of definite or probable thrombosis, repeat revascularization, and BARC bleeding>2 were 3.1%, 2.3%, and 4.2%, respectively. Predictive factors were diabetes mellitus, renal failure, atrial fibrillation, delay to reperfusion>6hours, ejection fraction<45%, Killip class III-IV, radial access, bivalirudin, drug-eluting stents, final TIMI flow of III, and incomplete revascularization at discharge. CONCLUSIONS: Notable registry findings include frequently delayed presentation and a high prevalence of adverse factors such as renal failure and multivessel disease. Positive procedure-related predictors include shorter delay, use of radial access, bivalirudin, drug-eluting stents, and complete revascularization before discharge.

INTRODUCTION AND OBJECTIVES: The recommendation for dual antiplatelet therapy following drug-eluting stent implantation ranges from 6 months to 12 months or beyond. Recent trials have suggested the safety of a 6-month dual antiplatelet therapy regimen, yet certain caveats to these studies limit the applicability of this shorter duration dual antiplatelet therapy strategy in real world settings. METHODS: A registry was constructed with consecutive recruitment of patients undergoing new-generation drug-eluting stent implantation and prescribed 6 months of dual antiplatelet therapy. Propensity score matching was undertaken with a historical cohort of patients treated with second-generation drug-eluting stents who received 12 months of dual antiplatelet therapy from the ESTROFA-2 registry. The sample size was calculated using a noninferiority basis and the primary endpoint was the combination of cardiac death, myocardial infarction, revascularization, or major bleeding at 12 months. RESULTS: The analysis included 1286 patients in each group, with no significant differences in baseline characteristics. The primary endpoint occurred in 5.0% and 6.6% in the 6-month and 12-month groups, respectively (P = .001 for noninferiority). The incidence of definite or probable stent thrombosis was 0.5% and 0.7% in the 6-month and 12-month groups, respectively (P = .4). Major bleeding events were lower in the 6-month group than in the 12-month group (0.8% vs 1.4%; P = .2) CONCLUSIONS: In selected patients in this large multicenter study, the safety and efficacy of a 6-month dual antiplatelet therapy regimen after implantation of new-generation drug-eluting stents appeared to be noninferior to those of a 12-month dual antiplatelet therapy regimen.
