RESUMEN
Multivalvular heart disease (MVHD) is present in one-third of patients with valvular heart disease (VHD). Compared to single VHD patients, these patients have a more significant hemodynamic impact and are often left under medical treatment. Most importantly, when undergoing multiple valve interventions, they show worse rates of heart failure and mortality. The guidelines-supported interventions in patients with MVHD in combined aortic regurgitation and mitral stenosis include percutaneous mitral balloon commissurotomy, open mitral commissurotomy, or surgical mitral valve replacement followed by transcatheter or surgical aortic valve replacement, trying to minimize the increased mortality risk of double-valve replacement. Simultaneous transcatheter valve replacement (STVR) for native MVHD is still off-label and not yet considered in clinical guidelines since the evidence of its results is limited to a few cases reported worldwide. However, fully percutaneous transfemoral STVR seems promising for MVHD patients thanks to its minimal invasiveness, the continuous improvement of the transcatheter heart valve devices, the likely shorter length of stay and the fastest recovery. To our knowledge, this is the first case ever reported of fully percutaneous STVR for native MVHD in aortic regurgitation and mitral stenosis. Deep understanding of both pathologies and their interactions, not only from a pathological point of view but from the procedural planning and procedural steps point of view is mandatory. Hereby we present the specific STVR procedural planning considerations, a step-by-step guide on how to perform an aortic and mitral STVR and its critical considerations, as well as the procedural and follow-up results.
RESUMEN
AIMS: In low-risk patients with severe aortic stenosis (AS), sutureless surgical aortic valve replacement (SU-SAVR) may be an alternative to transcatheter aortic valve implantation (TAVI). The risk of heart failure hospitalization (HFH) after aortic valve replacement (AVR) in this population is incompletely characterized. This study aims to investigate the incidence, predictors, and outcomes of HFH in patients undergoing SU-SAVR versus TAVI. METHODS AND RESULTS: Patients referred for AVR between 2013 and 2020 at two centres were consecutively included. The decision for SU-SAVR or TAVI was determined by a multidisciplinary Heart Team. Cox regression and competing risk analysis were conducted to assess adverse events. Of 594 patients (mean age 77.5 ± 6.4, 59.8% male), 424 underwent SU-SAVR, while 170 underwent TAVI. Following a mean follow-up of 34.1 ± 23.1 months, HFH occurred in 112 (27.8%) SU-SAVR patients and in 8 (4.8%) TAVI patients (P < 0.001). The SU-SAVR cohort exhibited higher all-cause mortality (138 [32.5%] patients compared with 30 [17.6%] in the TAVI cohort [P < 0.001]). These differences remained significant after sensitivity analyses with 1:1 propensity score matching for baseline variables. SU-SAVR with HFH was associated with increased all-cause mortality (61.6% vs. 23.1%, P < 0.001). Independent associates of HFH in SU-SAVR patients included diabetes, atrial fibrillation, chronic obstructive pulmonary disease, lower glomerular filtration rate and lower left ventricular ejection fraction. SU-SAVR patients with HFH had a 12-month LVEF of 59.4 ± 12.7. CONCLUSIONS: In low-risk AS, SU-SAVR is associated with a higher risk of HFH and all-cause mortality compared to TAVI. In patients with severe AS candidate to SU-SAVR or TAVI, TAVI may be the preferred intervention.
RESUMEN
Background: A blood multimarker approach may be useful to enhance risk stratification in patients undergoing TAVI. Objectives: The objective of this study was to determine the prognostic value of multiple blood biomarkers in transcatheter aortic valve implantation (TAVI) patients. Methods: In this prospective study, several blood biomarkers of cardiovascular function, inflammation, and renal function were measured in 362 patients who underwent TAVI. The cohort was divided into 3 groups according to the number of elevated blood biomarkers (ie, ≥ median value for the whole cohort) for each patient before the procedure. Survival analyses were conducted to evaluate the association between blood biomarkers and risk of adverse event following TAVI. Results: During a median follow-up of 2.5 (IQR: 1.9-3.2) years, 34 (9.4%) patients were rehospitalized for heart failure, 99 (27%) patients died, and 113 (31.2%) met the composite endpoint of all-cause mortality or heart failure rehospitalization. Compared to patients with 0 to 3 elevated biomarkers (referent group), those with 4 to 7 and 8 to 9 elevated biomarkers had a higher risk of all-cause mortality (HR: 1.54 [95% CI: 0.84-2.80], P = 0.16, and HR: 2.81 [95% CI: 1.53-5.15], P < 0.001, respectively) and of the composite endpoint (HR: 1.65 [95% CI: 0.95-2.84], P = 0.07, and HR: 2.67 [95% CI: 1.52-4.70] P < 0.001, respectively). Moreover, adding the number of elevated blood biomarkers into the clinical multivariable model provided significant incremental predictive value for all-cause mortality (Net Reclassification Index = 0.71, P < 0.001). Conclusions: An increasing number of elevated blood biomarkers is associated with higher risks of adverse clinical outcomes following TAVI. The blood multimarker approach may be helpful to enhance risk stratification in TAVI patients.

OBJECTIVES: Valve oversizing has been associated with reduced paravalvular leaks (PVL) and valve migration risk. However, no optimal cut-off oversizing value has been defined for the Evolut system (Medtronic). The aim of this study was to assess the relationship between the degree of oversizing and moderate-to-severe PVL and determine the optimal oversizing cut-off value. METHODS: We conducted a multicenter study that included 740 consecutive patients with multidetector computed tomography (CT) data. Valve size was selected according to manufacturer recommendations, with oversizing ranging from 10% to 30%. The primary endpoint was moderate-to-severe PVL. RESULTS: The median age was 84 years (79-87 years), with 58.4% women, and a median EuroSCORE II of 4.1% (2.4-7.3%). Moderate-to-severe PVL was observed in 7.0% of the patients. An inverse relationship was found between oversizing and both PVL (11.3%, 8.6%, 5.4%, and 2.7% for quartiles Q1 to Q4; P = .007) and the need for post-dilation (P = .016). The multivariable analysis showed an association between oversizing and PVL (OR: 0.915 for each 1%-increase, P = .002). The optimal oversizing cut-off value to predict PVL was 20%, and PVL was significantly higher in patients with oversizing less than 20% (10.5% vs.4.2%, P less than .001). There were no differences in major clinical events according to the degree of oversizing, and a higher oversizing did not translate into an increased risk of permanent pacemaker (18.4% vs18.3%, P = .976). CONCLUSIONS: In TAVR with the Evolut valve, a higher oversizing was associated with lower rates of moderate-to-severe PVL and a lower need for post-dilation, with no negative impact on procedural and early clinical outcomes. A 20% oversizing threshold could be suggested to reduce PVLs. Further prospective studies are warranted to validate optimal oversizing for this valve system.

OBJECTIVES: The SavvyWire(OpSens Medical) is a support wire for transcatheter aortic valve replacement (TAVR) procedures that, in addition to its dedicated left ventricle (LV) pacing capabilities, has a distal pressure sensor that measures live transvalvular hemodynamics during the procedure. We aimed to determine the safety, efficacy, and functionality of the SavvyWire during TAVR procedures in an all-comer population. METHODS: We performed a multicentric, prospective, observational, single-arm, all-comers registry of patients with symptomatic, severe aortic stenosis undergoing TAVR in 3 Canadian centers. Data were collected in a dedicated database, and pre-specified questionnaires were fulfilled by the heart team implanters after each procedure. RESULTS: A total of 60 patients were included (mean age: 78.6 ± 7.2 years; 51% women; mean Society of Thoracic Surgeons score: 2.2 ± 1.6%). TAVR was performed through a transfemoral approach in 90% of cases, and balloon- and self-expandable valves were used in 73% and 27% of patients, respectively. There were no cases of LV perforation, guidewire deformation, significant loss of capture, or major software malfunction. The rate of successful delivery of the TAVR system was 100%, and effective LV pacing was achieved in 98% of patients. The pre-TAVR mean gradient was 39 ± 14 mm Hg while the final post-TAVR gradient was 8 ± 5 mm Hg; the mean aortic systolic pressure during rapid pacing was 54 ± 12 mm Hg. In 97% of the TAVR procedures, SavvyWire's functionality was reported to be better or similar to other TAVR workhorse support wires. CONCLUSIONS: SavvyWire was safe, effective, and functional for live transvalvular hemodynamic evaluation and rapid pacing during TAVR procedures. More studies with larger sample sizes and comparison against different wires and gradient measurement methods are warranted.

The growing number of candidates for transcatheter aortic valve replacement (TAVR) has increased the interest in the concomitant presence of coronary artery disease (CAD) and severe aortic stenosis (AS), prompting the need to define the appropriate revascularization strategy for each case. The reported prevalence of concurrent AS and CAD has varied over the years on the basis of the CAD definition and the population evaluated. Revascularization for treating CAD in patients with severe AS involves additional interventions that could impact outcomes. The addition of coronary artery bypass grafting (CABG) to surgical aortic valve replacement (SAVR) has demonstrated favourable effects on long-term prognosis, while the impact of adding percutaneous coronary intervention (PCI) to TAVR may depend on the CAD complexity and the feasibility of achieving complete or reasonably incomplete revascularization. Furthermore, the comparison between SAVR+CABG and TAVR+PCI in low-intermediate surgical risk and low-intermediate complex CAD patients did not reveal differences in all-cause mortality or stroke between the groups. However, there is some evidence showing a lower incidence of major cardiovascular events with the SAVR+CABG strategy for patients with complex CAD. Thus, SAVR+CABG seems to be the best option for patients with low-intermediate surgical risk and complex CAD, and TAVR+PCI for high surgical risk patients seeking complete and/or reasonable incomplete revascularization. After deciding between TAVR+PCI or SAVR+CABG, factors such as timing for PCI, low ejection fraction, coronary reaccess, and valve durability must be considered. Finally, alternative methods for assessing CAD severity are currently under evaluation to ascertain their real value for guiding revascularization in patients with severe AS with CAD.

Introducción y objetivos: Evaluar la prevalencia, las características clínicas y el impacto de la angina en pacientes con estenosis aórtica sometidos a implante percutáneo de válvula aórtica (TAVI). Métodos: Se analizó a 1.687 pacientes consecutivos con estenosis aórtica sometidos a TAVI, clasificados en función de la presencia o ausencia basal de angina. Los datos basales, del procedimiento y del seguimiento se recogieron en una base de datos local. Resultados: Un total de 497 pacientes (29%) presentaban angina antes del TAVI. Los pacientes con angina basal presentaban peor clase funcional (NYHA> II, el 69% frente al 63%; p=0,017) y una mayor prevalencia de enfermedad coronaria (el 74% frente al 56%; p <0,001). La angina basal no mostró impacto pronóstico a 1 año en mortalidad por cualquier causa (HR=1,02; IC95%, 0,71-1,48; p=0,898) ni en mortalidad cardiovascular (HR=1,2; IC95%, 0,69-2,11; p=0,517). Sin embargo, la persistencia de angina 30 días después del procedimiento se asoció con un incremento en la mortalidad a 1 año, tanto total (HR=4,86; IC95%, 1,71-13,8; p=0,003) como de causa cardiovascular (HR=20,7; IC95%, 3,50-122,6; p=0,001). Conclusiones: Más de un cuarto de los pacientes con estenosis aórtica sometidos a TAVI tenían angina antes del procedimiento. La angina basal no mostró impacto pronóstico alguno. Sin embargo, la persistencia de angina 30 días después del procedimiento se asoció con una mayor mortalidad al año.(AU)
Introduction and objectives: To evaluate the prevalence, clinical characteristics, and outcomes of patients with angina undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Methods: A total of 1687 consecutive patients with severe aortic stenosis undergoing TAVR at our center were included and classified according to patient-reported angina symptoms prior to the TAVR procedure. Baseline, procedural and follow-up data were collected in a dedicated database. Results: A total of 497 patients (29%) had angina prior to the TAVR procedure. Patients with angina at baseline showed a worse New York Heart Association (NYHA) functional class (NYHA class> II: 69% vs 63%; P=.017), a higher rate of coronary artery disease (74% vs 56%; P <.001), and a lower rate of complete revascularization (70% vs 79%; P <.001). Angina at baseline had no impact on all-cause mortality (HR, 1.02; 95%CI, 0.71-1.48; P=.898) and cardiovascular mortality (HR, 1.2; 95%CI, 0.69-2.11; P=.517) at 1 year. However, persistent angina at 30 days post-TAVR was associated with increased all-cause mortality (HR, 4.86; 95%CI, 1.71-13.8; P=.003) and cardiovascular mortality (HR, 20.7; 95%CI, 3.50-122.6; P=.001) at 1-year follow-up. Conclusions: More than one-fourth of patients with severe aortic stenosis undergoing TAVR had angina prior to the procedure. Angina at baseline did not appear to be a sign of a more advanced valvular disease and had no prognostic impact; however, persistent angina at 30 days post-TAVR was associated with worse clinical outcomes.(AU)

Patent foramen ovale (PFO) closure, along with medical therapy, has emerged as the therapeutic gold standard in younger (<60-year-old) patients with a PFO-related stroke for preventing recurrent events. However, PFO management guidelines lack definite recommendations for older (>60 years) patients with a PFO-related cerebrovascular event, a complex group of patients who were mostly excluded from PFO closure clinical trials. Nevertheless, several studies have shown a higher prevalence of PFO among older patients with cryptogenic stroke, and its presence has been associated with an increased risk of recurrent events. Furthermore, older patients exhibit a higher prevalence of high-risk PFO anatomical features, present inherent age-related risk factors that might increase the risk of paradoxical embolism through a PFO, and have a higher incidence of ischemic events after a PFO-related event. Additionally, observational studies have shown the safety and preliminary efficacy of PFO closure in older PFO-related stroke patients. Yet, higher rates of recurrent cerebrovascular events and new-onset atrial fibrillation were observed in some studies among older patients compared to their younger counterparts. After careful case-by-case evaluation, including the assessment of hidden potential cardioembolic sources of a cryptogenic stroke other than PFO, transcatheter PFO closure might be a safe and effective therapeutic option for preventing recurrent thromboembolic events in patients >60 years with a high-risk PFO-associated stroke. Ongoing trials will provide important insights into the role of PFO closure in the elderly population.
RESUMEN
BACKGROUND: The updated Valve Academic Research Consortium (VARC) definition for bleeding events after transcatheter aortic valve replacement (TAVR) lacks of clinical validation. OBJECTIVES: The aim of this study was to determine the incidence, predictors, and clinical impact of bleeding events following TAVR as defined by recent VARC-3 criteria. METHODS: A total of 2,384 consecutive patients with severe symptomatic aortic stenosis undergoing TAVR were included. Early (at index hospitalization) and late (after hospital discharge) bleeding complications were defined according to VARC-3 criteria as type 1, 2, 3, or 4. Baseline, procedural, and follow-up (24 [IQR: 12-43] months) data were prospectively collected. RESULTS: Bleeding events occurred in 761 patients (31.9%): types 1, 2, 3, and 4 in 169 (22.2%), 399 (52.4%), 149 (19.6%), and 44 (5.8%) patients, respectively. The primary vascular access site and gastrointestinal locations were the most common bleeding sources among early and late bleeding events, respectively. Female sex, thoracotomy access, larger (14-F) sheath use, and dual antiplatelet therapy determined an increased risk of early bleeding events (P < 0.02 for all). The use of the radial artery for secondary access was associated with a significant risk reduction of early bleeding (P < 0.001). Type 2 and type 3 events were associated with an increased mortality risk at 30-day (HR: 2.94 [95% CI: 1.43-6.03; P = 0.003] and HR: 4.91 [95% CI: 2.19-11.03; P < 0.001], respectively) and 1-year (HR: 1.86 [95% CI: 1.28-2.69; P = 0.001] and HR: 2.28 [95% CI: 1.41-3.66; P = 0.001], respectively) follow-up. A similar prognostic pattern was observed when applying VARC-2 criteria but with a much lower global incidence of early bleeding events (19% vs 27%; P < 0.001). CONCLUSIONS: Bleeding events after TAVR were associated with poorer short- and long-term survival. The magnitude of this correlation was proportional to bleeding severity defined according to VARC-3 criteria. Further studies on bleeding prevention following TAVR are warranted to improve procedural safety and patient prognosis.

Background Scarce data exist on sex differences in patients with cryptogenic cerebrovascular events undergoing patent foramen ovale (PFO) closure. This study aimed to determine the sex differences in clinical profile, procedural characteristics, and long-term outcomes of patients with cryptogenic cerebrovascular events undergoing PFO closure. Methods and Results A retrospective cohort was used, including 1076 consecutive patients undergoing PFO closure because of a cryptogenic cerebrovascular event. Patients were divided into 2 groups: 469 (43.6%) women and 607 (56.4%) men. The median follow-up was 3 years (interquartile range, 2-8 years). Women were younger (46±13 versus 50±12 years; P<0.01) and had a higher risk of paradoxical embolism score (6.9±1.7 versus 6.6±1.6; P<0.01). Procedural characteristics and postprocedural antithrombotic therapy were similar. At follow-up, there were no differences in atrial fibrillation (women versus men: 0.47 versus 0.97 per 100 patient-years; incidence rate ratio [IRR], 0.55 [95% CI, 0.27-1.11]; P=0.095; adjusted P=0.901), stroke (0.17 versus 0.07 per 100 patient-years; IRR, 2.58 [95% CI, 0.47-14.1]; P=0.274; adjusted P=0.201), or transient ischemic attack (0.43 versus 0.18 per 100 patient-years; IRR, 2.58 [95% CI, 0.88-7.54]; P=0.084; adjusted P=0.121); nevertheless, women exhibited a higher incidence of combined ischemic cerebrovascular events (0.61 versus 0.26 per 100 patient-years; IRR, 2.58 [95% CI, 1.04-6.39]; P=0.041; adjusted P=0.028) and bleeding events (1.04 versus 0.45 per 100 patient-years; IRR, 2.82 [95% CI, 1.41-5.65]; P=0.003; adjusted P=0.004). Conclusions Compared with men, women with cryptogenic cerebrovascular events undergoing PFO closure were younger and had a higher risk of paradoxical embolism score. After a median follow-up of 3 years, there were no differences in stroke events, but women exhibited a higher rate of combined (stroke and transient ischemic attack) cerebrovascular events and bleeding complications. Additional studies are warranted to clarify sex-related outcomes after PFO closure further.

BACKGROUND: Device-related thrombus (DRT) remains one of the main concerns after left atrial appendage occlusion (LAAO). Several risk factors have been proposed, but most cannot be modulated. A modifiable factor such as device implantation depth is a potential target to adjust the risk for DRT. OBJECTIVES: The aim of this study was to assess the impact of LAAO device implantation depth as a predisposing factor for DRT. METHODS: The study included patients who underwent successful LAAO at 9 centers in Europe and Canada. Patients were classified into 2 groups: proximal device implantation (covered pulmonary ridge [PR] in the lobe and disc cohort or <5 mm from the PR in the single-lobe cohort) and distal device implantation (uncovered PR in the disc and lobe cohort and ≥5 mm in the single-lobe cohort). RESULTS: A total of 1,317 patients were included. Among these, proximal and distal device implantation was achieved in 732 (55%) and 585 (45%) patients, respectively. No differences in procedural outcomes were observed between the groups. At follow-up, patients with proximal implantation had a lower incidence of DRT (2.3%) than those with distal implantation (12.2%) (P < 0.001). Deeper device implantation and a larger uncovered left atrial appendage area were associated with a higher incidence of DRT (P < 0.001), regardless of device type. In multivariable analysis, distal implant (HR: 5.92; 95% CI: 3.39-10.36) and no or single antiplatelet therapy (HR: 1.62; 95% CI: 0.99-2.62) emerged as independent predictors of DRT. CONCLUSIONS: LAAO device implantation depth is an independent risk factor for DRT. Deeper device implantation and larger uncovered left atrial appendage areas were associated with a higher incidence of DRT.

Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) is recommended in revascularization guidelines for intermediate lesions. However, recent studies comparing FFR-guided PCI with non-physiology-guided revascularization have reported conflicting results. PubMed and Embase were searched for studies comparing FFR-guided PCI with non-physiology-guided revascularization strategies (angiography-guided, intracoronary imaging-guided, coronary artery bypass grafting). Data were pooled by meta-analysis using random-effects model. 26 studies enrolling 78,897 patients were included. FFR-guided PCI as compared to non-physiology-guided coronary revascularization had lower risk of all-cause mortality (odds ratio [OR] 0.79 95% confidence interval [CI] 0.64-0.99, I2 = 53%) and myocardial infarction (MI) (OR 0.74 95% CI 0.59-0.93, I2 = 44.7%). However, no differences between groups were found in terms of major adverse cardiac events (MACEs) (OR 0.86 95% CI 0.72-1.03, I2 = 72.3%) and repeat revascularization (OR 1 95% CI 0.82-1.20, I2 = 43.2%). Among patients with coronary artery disease (CAD), FFR-guided PCI as compared to non-physiology-guided revascularization was associated with a lower risk of all-cause mortality and MI.
RESUMEN
BACKGROUND: The Valve Academic Research Consortium (VARC)-3 definition for myocardial injury after transcatheter aortic valve replacement (TAVR) lacks of clinical validation. OBJECTIVES: This study sought to determine the incidence, predictors, and clinical impact of periprocedural myocardial injury (PPMI) following TAVR as defined by recent VARC-3 criteria. METHODS: We included 1,394 consecutive patients who underwent TAVR with a new-generation transcatheter heart valve. High-sensitivity troponin levels were assessed at baseline and within 24 hours after the procedure. PPMI was defined according to VARC-3 criteria as an increase ≥70 times in troponin levels (vs ≥15 times according to the VARC-2 definition). Baseline, procedural, and follow-up data were prospectively collected. RESULTS: PPMI was diagnosed in 193 (14.0%) patients. Female sex and peripheral artery disease were independent predictors of PPMI (P < 0.01 for both). PPMI was associated with a higher risk of mortality at 30-day (HR: 2.69, 95% CI: 1.50-4.82; P = 0.001) and 1-year (for all-cause mortality, HR: 1.54; 95% CI: 1.04-2.27; P = 0.032; for cardiovascular mortality, HR: 3.04; 95% CI: 1.68-5.50; P < 0.001) follow-up. PPMI according to VARC-2 criteria had no impact on mortality. CONCLUSIONS: About 1 out of 10 patients undergoing TAVR in the contemporary era had PPMI as defined by recent VARC-3 criteria, and baseline factors like female sex and peripheral artery disease determined an increased risk. PPMI had a negative impact on early and late survival. Further studies on the prevention of PPMI post-TAVR and implementing measures to improve outcomes in PPMI patients are warranted.

METHODS: A total of 1687 consecutive patients with severe aortic stenosis undergoing TAVR at our center were included and classified according to patient-reported angina symptoms prior to the TAVR procedure. Baseline, procedural and follow-up data were collected in a dedicated database. RESULTS: A total of 497 patients (29%) had angina prior to the TAVR procedure. Patients with angina at baseline showed a worse New York Heart Association (NYHA) functional class (NYHA class> II: 69% vs 63%; P=.017), a higher rate of coronary artery disease (74% vs 56%; P <.001), and a lower rate of complete revascularization (70% vs 79%; P <.001). Angina at baseline had no impact on all-cause mortality (HR, 1.02; 95%CI, 0.71-1.48; P=.898) and cardiovascular mortality (HR, 1.2; 95%CI, 0.69-2.11; P=.517) at 1 year. However, persistent angina at 30 days post-TAVR was associated with increased all-cause mortality (HR, 4.86; 95%CI, 1.71-13.8; P=.003) and cardiovascular mortality (HR, 20.7; 95%CI, 3.50-122.6; P=.001) at 1-year follow-up. CONCLUSIONS: More than one-fourth of patients with severe aortic stenosis undergoing TAVR had angina prior to the procedure. Angina at baseline did not appear to be a sign of a more advanced valvular disease and had no prognostic impact; however, persistent angina at 30 days post-TAVR was associated with worse clinical outcomes.

AIMS: Temporary dual antiplatelet therapy (DAPT) is recommended following patent foramen ovale (PFO) percutaneous closure although its benefit, compared to single antiplatelet therapy (SAPT), has not been demonstrated in this setting. We aimed at assessing outcomes following PFO closure according to the antiplatelet strategy at discharge. METHODS AND RESULTS: The ambispective AIR-FORCE cohort included consecutive patients from seven centres in France and Canada undergoing PFO closure and discharged without anticoagulation. Patients treated in French and Canadian centres were mostly discharged with DAPT and SAPT, respectively. The primary endpoint was the composite of death, stroke, transient ischaemic attack, peripheral embolism, myocardial infarction, or BARC type ≥2 bleeding with up to 5 years of follow-up. The impact of the antiplatelet strategy on outcomes was evaluated with a marginal Cox model (cluster analyses per country) with inverse probability weighting according to propensity score. A total of 1532 patients (42.2% female, median age: 49 [40-57] years) were included from 2001 to 2022, of whom 599 (39.1%) were discharged with SAPT and 933 (60.9%) with DAPT, for ≤3 months in 894/923 (96.9%) cases. After a median follow-up of 2.4 [1.1-4.4] years, a total of 58 events were observed. In the weighted analysis, the rate of the primary endpoint up to 5 years was 7.8% in the SAPT strategy and 7.3% in the DAPT strategy (weighted hazard ratio 1.04, 95% confidence interval 0.59-1.83). CONCLUSION: The antiplatelet strategy following PFO closure did not seem to impact clinical outcomes, thus challenging the current recommendations of temporary DAPT.
