Eligibility to COAPT trial in the daily practice: A real-world experience.

BACKGROUND: The COAPT Trial was the first ever to demonstrate a survival benefit in treating functional mitral regurgitation (FMR). That was achieved through transcatheter mitral repair in selected patients. The exact proportion of patients fulfilling COAPT selection criteria in the real-world is unknown. AIMS: To assess the applicability of COAPT criteria in real world and its impact on patients' survival. METHODS: We assessed the clinical data and follow-up results of all consecutive patients admitted for FMR at our Department between January 2016 and May 2021 according to COAPT eligibility. COAPT eligibility was retrospectively assessed by a cardiac surgeon and a cardiologist. RESULTS: Among 394 patients, 56 (14%) were COAPT eligible. The most frequent reasons for exclusion were MR ≤ 2 (22%), LVEF < 20% or >50% (19%), and non-optimized GDMT (21.3%). Among Non-COAPT patients, weighted 4-year survival was higher in patients who received MitraClip compared to those who were left in optimized medical therapy (91.5% confidence interval [CI: 0.864, 0.96] vs. 71.8% [CI: 0.509, 0.926], respectively, p = 0.027). CONCLUSIONS: Only a minority (14%) of real-world patients with FMR referred to a tertiary hospital fulfilled the COAPT selection criteria. Among Non-COAPT patients, weighted 4-year survival was higher in patients who received MitraClip compared to those who were left in optimized medical therapy (91.5% [0.864, 0.96] vs. 71.8% [0.509, 0.926], respectively, p = 0.027).

A comprehensive and easy-to-use ECG algorithm to predict the coronary occlusion site in ST-segment elevation myocardial infarction.

BACKGROUND: Several electrocardiogram (ECG) criteria have been proposed to predict the location of the culprit occlusion in specific subsets of patients presenting with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to develop, through an independent validation of currently available criteria, a comprehensive and easy-to-use ECG algorithm, and to test its diagnostic performance in real-world clinical practice. METHODS: We analyzed ECG and angiographic data from 419 consecutive STEMI patients submitted to primary percutaneous coronary intervention over a one-year period, dividing the overall population into derivation (314 patients) and validation (105 patients) cohorts. In the derivation cohort, we tested >60 previously published ECG criteria, using the decision-tree analysis to develop the algorithm that would best predict the infarct-related artery (IRA) and its occlusion level. We further assessed the new algorithm diagnostic performance in the validation cohort. RESULTS: In the derivation cohort, the algorithm correctly predicted the IRA in 88% of cases and both the IRA and its occlusion level (proximal vs mid-distal) in 71% of cases. When applied to the validation cohort, the algorithm resulted in 88% and 67% diagnostic accuracies, respectively. In a real-world comparative test, the algorithm performed significantly better than expert physicians in identifying the site of the culprit occlusion (P = .026 vs best cardiologist and P < .001 vs best emergency medicine doctor). CONCLUSIONS: Derived from an extensive literature review, this comprehensive and easy-to-use ECG algorithm can accurately predict the IRA and its occlusion level in all-comers STEMI patients.

Evolution of interventional imaging in structural heart disease.

Treatments for structural heart diseases (SHD) have been considerably evolved by the widespread of transcatheter approach in the last decades. The progression of transcatheter treatments for SHD was feasible due to the improvement of devices and the advances in imaging techniques. In this setting, the cardiovascular imaging is pivotal not only for the diagnosis but even for the treatment of SHD. With the aim of fulfilling these tasks, a multimodality imaging approach with new imaging tools for pre-procedural planning, intra-procedural guidance, and follow-up of SHD was developed. This review will describe the current state-of-the-art imaging techniques for the most common percutaneous interventions as well as the new imaging tools. The imaging approaches will be addressed describing the use in pre-procedural planning, intra-procedural guidance, and follow-up.

Myocardial injury in patients with SARS-CoV-2 pneumonia: Pivotal role of inflammation in COVID-19.

AIMS: Infection by SARS-CoV-2 may result in a systemic disease and a proportion of patients ranging 15%-44% experienced cardiac injury (CI) diagnosed by abnormal troponin levels. The aim of the present study was to analyse the clinical characteristics of a large series of hospitalized patients for COVID-19 in order to identify predisposing and/or protective factors of CI and the outcome. METHODS AND RESULTS: This is an observational, retrospective study on patients hospitalized in two Italian centres (San Raffaele Hospital and Cremona Hospital) for COVID-19 and at least one high-sensitivity cardiac troponin (hs-cTnt) measurement during hospitalization. CI was defined if at least one hs-cTnt value was above the 99th percentile. The primary end-point was the occurrence of CI during hospitalization. We included 750 patients (median age 67, IQR 56-77 years; 69% males), of whom 46.9% had history of hypertension, 14.7% of chronic coronary disease and 22.3% of chronic kidney disease (CKD). Abnormal troponin levels (median troponin 74, IQR 34-147 ng/l) were detected in 390 patients (52%) during the hospitalization. At multivariable analysis age, CKD, cancer, C-reactive protein (CRP) levels were independently associated with CI. Independent predictors of very high troponin levels were chronic kidney disease and CRP levels. Patients with CI showed higher rate of all-cause mortality (40.0% vs. 9.1%, p = 0.001) compared to those without CI. CONCLUSION: This large, multicentre Italian study confirmed the high prevalence of CI and its prognostic role in hospitalized patients with COVID-19, highlighting the leading role of systemic inflammation for the occurrence of CI.

Outcome of left atrial appendage closure using cerebral protection system for thrombosis: no patient left behind.

BACKGROUND: Left atrial appendage (LAA) thrombosis increases the risk of stroke and its management has to be assessed. The aim of the present study is to evaluate short and long-term safety and efficacy of a standardized approach of percutaneous LAA closure (LAAC) routinely using a cerebral protection device (CPD) in patients with LAA thrombosis or sludge (LAAT). METHODS: We prospectively enrolled 14 consecutive patients with atrial fibrillation complicated by LAAT presenting in a high-volume tertiary center. In seven patients (50%) LAAT was found after anticoagulant withdrawal for severe bleedings and in the remaining half LAAT was found despite appropriate anticoagulant therapy. All patients were treated with a standardized interventional approach of LAAC routinely using a CPD and guided by transoesophageal echocardiography. RESULTS: Mean age was 68 ± 14 years and nine patients (64%) were male. Mean CHA2 DS2 -VASc and HAS-BLED scores were 3.3 ± 1.6 and 2.3 ± 1.1, respectively. Six patients (42.8%) presented organized thrombi while eight LAA sludge (57.1%). In 13 patients (92.8%) CPD was positioned through a right radial arterial access. Procedural success was achieved in all patients. In one patient we assisted to embolization of the thrombus during deployment of the device in the absence of neurological consequences. During a mean follow up of 426 ± 307 days, one patient died for non-cardiac cause while no embolic event or major bleeding were reported. CONCLUSION: In an unselected cohort, LAAC with the systematic use of CPD was a feasible, safe and effective therapeutic option for LAAT both acutely and after long-term follow-up.

Use of edge-to-edge percutaneous mitral valve repair for severe mitral regurgitation in cardiogenic shock: A multicenter observational experience (MITRA-SHOCK study).

OBJECTIVES: The aim of this study was to evaluate the impact of edge-to-edge PMVR on short and mid-term clinical outcomes in patients with CS and severe MR. BACKGROUND: Severe mitral regurgitation (MR) in the setting of cardiogenic shock (CS) is associated with three times higher risk of 1-year mortality. In refractory CS, edge-to-edge percutaneous mitral valve repair (PMVR) can be a potential therapeutic option. METHODS: We retrospectively included consecutive patients with refractory CS and concomitant severe MR treated with MitraClip® system. CS was defined according to the criteria used in the SHOCK trial and procedural success according to Mitral Valve Academic Research Consortium (MVARC) criteria. The 30-day and 6-month mortality were the primary and secondary endpoints respectively. RESULTS: Thirty-one patients (median age 73 years [interquartile range, IQR 66-78], 25.8% female), STS mortality score 37.9 [IQR 30.4-42.4]), with CS and concomitant severe MR treated with edge-to-edge PMVR were retrospectively enrolled. Procedural success was 87.1%. Thirty-day and 6-month survival rates were 78.4 and 45.2% respectively. Univariate Cox Regression Model analysis showed that procedural success was a predictor of both 30-day (HR = 0.12, 95% CI 0.03-0.55, p < .01) and 6-month survival (HR = 0.22, 95% CI 0.06-0.84, p = .027). CONCLUSIONS: Edge-to-edge PMVR in patients with CS and concomitant severe MR was associated with good procedural safety and success with acceptable short and mid-term survival rates. It could be considered a bailout option in this setting of patients.

Subclinical myocardial dysfunction in patients recovered from COVID-19.

BACKGROUND: Myocardial injury (MI) can be detected during the acute phase of Coronavirus disease 19 (COVID-19) and is associated with a dismal prognosis. Recent imaging studies described the persistence of cardiac abnormalities after the recovery. The aim of the study was to investigate the spectrum of cardiac abnormalities at mid-term follow-up in patients recovered from COVID-19 using clinical assessment, laboratory tests, and imaging evaluation with comprehensive echocardiography. METHODS: This is an observational, cross-sectional study assessing an unselected cohort of consecutive patients recovered from COVID-19. MI was defined by elevated plasma levels of high sensitive troponin T (hsTnT). At the follow-up, a complete examination including echocardiography was performed. RESULTS: The 123 patients included were divided into two groups according to the presence of MI during hospitalization: group A (without MI) and group B (with MI). After a median of 85 days, group B patients were more frequently symptomatic for dyspnea and had significantly higher values of hsTnT and N-Terminal prohormone of Brain Natriuretic Peptide (NT-proBNP), compared to Group A. No differences between the two groups in left nor right ventricle dimension and ejection fraction were found. However, in group B a significant reduction of mean left ventricle global longitudinal strain was observed (-15.7±.7 vs -18.1± .3 in group A, p < 0.001), together with higher frequency of impaired diastolic function and higher values of pulmonary pressure. CONCLUSIONS: In patients recovered from COVID-19, echocardiography with speckle-tracking analysis may be an useful imaging tool to identify subclinical myocardial dysfunction and potentially guide management strategies.

Aortic valve area calculation using 3D transesophageal echocardiography: Implications for aortic stenosis severity grading.

AIMS: Aortic stenosis (AS) grading by 2D-transthoracic echocardiography (2D-TTE) aortic valve area (AVA) calculation is limited by left ventricular outflow tract (LVOT) area underestimation. The combination of Doppler parameters with 3D LVOT area obtained by multidetector computed tomography (MDCT) can improve AS grading, reconciling discordant 2D-TTE findings. This study aimed to systematically evaluate the role of 3D-transesophageal echocardiography (3D-TEE) in AS grading using MDCT as reference standard. METHODS AND RESULTS: 288 patients (81 ± 6.3 years, 52.4% female) with symptomatic AS underwent 2D-TTE, 3D-TEE, and MDCT for transcatheter aortic valve implantation. Doppler parameters were combined with 3D LVOT areas measured by manual and semi-automated software 3D-TEE and by MDCT to calculate AVA, reassessing AS severity. Both 3D-TEE modalities demonstrated good correlation with MDCT, with excellent intra-observer and inter-observer variability. Compared to MDCT, 3D-TEE measurements significantly underestimated AVA (PANOVA  < .0001), although the difference was clinically acceptable. Compared to 2D-TTE, 3D-TEE manual and semi-automated software reclassified severe AS in 21.9% and 25.2% of cases, respectively (P < .0001), overcame grading parameters discordance in more than 40% of cases in patients with low-gradient AS (P < .0001) and reduced the proportion of low-flow states in nearly 75% of cases when combined to stroke volume index assessment (P < .0001). 3D-TEE imaging modalities showed a reduction in the proportion of patients with low-gradient and pathological AVA as defined by 2D-TTE, and improved AVA and mean pressure gradient agreement with current guidelines cutoff values. CONCLUSION: 3D-TEE AVA calculation is a reliable tool for AS grading with excellent reproducibility and good correlation with MDCT measurements.

Right ventricular function after cardiac surgery: the diagnostic and prognostic role of echocardiography.

Cardiac surgical techniques and circulatory supports have strongly evolved in the last years. Right ventricular (RV) function during the post-operatory period is still subject of study, although its relevant prognostic impact has been variably described in different papers. RV post-surgical dysfunction's underlying mechanisms are still not clear and include a different hypothesis. Echocardiography, with both first and second level parameters, offers the possibility to accurately analyze the right ventricle and optimize these patients' management. This paper describes the pathophysiology of the right ventricle, the most used echo indexes of RV function, whether they alter after surgery, the different supposed mechanisms of RV dysfunction and its role in the prognosis of patients undergoing cardiac surgery.

Echocardiographic features of post-transcatheter aortic valve implantation thrombosis and endocarditis.

BACKGROUND: Transcatheter heart valve thrombosis (THV-t) and endocarditis (THV-e) are relevant complications after transcatheter aortic valve implantation (TAVI). Transcatheter heart valve (THV) dysfunction definition is mostly based on Doppler (stenosis/regurgitation) without considering leaflets characteristics. PURPOSE: To evaluate the additional diagnostic value of leaflets echocardiographic features over Doppler when prosthetic valve complication is suspected. METHODS: Among 621 post-TAVI patients, 128 cases with probable valve complication were identified. THV-t was finally diagnosed in 13 patients (10%) and THV-e in 8 (6%), while the remaining 107 (84%) had no definitive diagnosis of thrombosis/endocarditis (THV-no). We analyzed at 2 time points (baseline and follow-up) both traditional Doppler parameters and leaflets morpho-functional features. RESULTS: Both Doppler and leaflets parameters showed high sensitivity (sensitivity 92%) and low specificity (ranging from specificity 32% to 74%) in detecting THV-t. Interestingly, the combination of mean aortic pressure gradient ≥20 mm Hg and leaflet thickening significantly improved the specificity of echocardiography for diagnosis of THV thrombosis (specificity 94%). On the other hand, echocardiographic diagnosis of THV endocarditis remained limited by very low sensitivity despite showing high specificity. CONCLUSIONS: The combination of Doppler and leaflets parameters can improve the echocardiographic diagnosis of THV thrombosis in post-TAVI patients with suspicious symptoms, via a significant increase in the overall test specificity. This would potentially allow more rational gatekeeping to more expensive/invasive diagnostic examinations (eg, CT scan) or therapeutic trials (eg, unnecessary anticoagulation).

Speckle tracking analysis in intensive care unit: A toy or a tool?

The use of conventional echocardiography in the intensive care unit (ICU) is today established to assess left and right ventricular systolic function, for preload determination and procedural guidance. Next step in ICU echocardiography could be the use of novel ultrasound techniques such as strain echocardiography to assist in the management of patients with acute coronary syndrome, heart failure, or pulmonary embolism. This review has gathered the available evidence supporting the incremental value of strain in the diagnostic workup of cardiac diseases treated in ICU.

Left atrial appendage closure: A single center experience and comparison of two contemporary devices.

OBJECTIVES: To compare indications and clinical outcomes of two contemporary left atrial appendage (LAA) percutaneous closure systems in a "real-world" population. BACKGROUND: Percutaneous LAA occlusion is an emerging therapeutic option for stroke prevention in atrial fibrillation. Some questions however remain unanswered, such as the applicability of results of randomized trials to current clinical practice. Moreover, currently available devices have never been directly compared. METHODS: We retrospectively analyzed consecutive patients who underwent LAA closure at San Raffaele Hospital, Milan, Italy between 2009 and 2015. Clinical indications and device selection were left to operators' decision; routine clinical and transesophageal echocardiography (TEE) follow-up was performed. RESULTS: One-hundred and sixty-five patients were included in the study, of which 99 were treated with the Amplatzer Cardiac Plug (ACP) and 66 with the Watchman system. During the follow-up period (median 15 months, interquartile range 6-26 months) five patients died. The incidence of ischemic events was low, with one patient suffering a transient ischemic attack and no episodes recorded of definitive strokes. Twenty-six leaks ≥1 mm were detected (23%); leaks were less common with the ACP and with periprocedural three-dimensional TEE evaluation, but were not found to correlate with clinical events. Clinical outcomes were comparable between the two devices. CONCLUSIONS: Our data show excellent safety and efficacy of LAA closure, irrespectively of the device utilized, in a population at high ischemic and hemorrhagic risk. The use of ACP and 3D-TEE minimized the incidence of residual leaks; however, the clinical relevance of small peri-device flow warrants further investigation. © 2016 Wiley Periodicals, Inc.

Takotsubo cardiomyopathy and neurogenic stunned myocardium: similar albeit different.

We demonstrate that in patients with stress cardiomyopathy the type of triggering event is associated with different clinical, instrumental, and laboratory features that characterize the phenotype at presentation.

Mycobacterium abscessus hand-and-foot disease in children: rare or emerging disease?

Mycobacterium abscessus is emerging as an important cause of cutaneous infections in sporadic cases and outbreak settings. Although immunosuppressed or elderly patients are most commonly affected, in 2006 an outbreak of clinically distinct cutaneous lesions on the hands and feet caused by M. abscessus in a population of healthy children using a public swimming pool was reported. This article describes an outbreak of skin infection in a population of healthy Italian children attending the same school and using the same swimming pool. In January 2010 we identified three children with multiple, painful nodules on the palms and soles. M. abscessus was isolated from one child's lesions. A public health investigation was conducted and a team of dermatologists and public health officers visited all of the children; 514 children were screened and 29 cases were identified overall. All of the affected children had used the school's swimming pool. These children were treated with oral clarithromycin for 4 to 8 weeks. Because of the long period of time between the presentation and diagnosis of the first cases, the possibility that the number of cases may have been underestimated cannot be excluded. To our knowledge, this is the second largest reported cluster of M. abscessus skin infection suspected to be related to swimming pool exposure in a population of otherwise healthy children. It is unclear whether this disease is rare or should be considered as an emerging clinical entity.

Multimodality imaging of caseous mitral annular calcification complicated by possible systemic embolizations.

We demonstrate the case of a man presenting with chest pain in which an initial assessment with echocardiography and, subsequently, with cardiac computed tomography led to a final diagnosis of caseous mitral annular calcification complicated by multiple embolizations.

Quantification of Mitral Regurgitation in Mitral Valve Prolapse by Three-Dimensional Vena Contracta Area: Derived Cutoff Values and Comparison With Two-Dimensional Multiparametric Approach.

BACKGROUND: Echocardiographic grading of mitral regurgitation (MR) in mitral valve prolapse (MVP) is challenging. Three-dimensional (3D) vena contracta area (VCA) has been proposed as a valuable method. However, data defining the cutoff values of severity and validation in the subset of patients with MVP are scarce. The aim of this study was to validate the 3D VCA by 3D color-Doppler transesophageal echocardiography (TEE) in patients with MVP and to define the cutoff values of severity grading. The secondary aim was to compare 3D VCA to the effective regurgitant orifice area estimation by proximal isovelocity surface area (EROA-PISA) method. METHODS: A total of 1,138 patients with at least moderate MR who underwent TEE were included. Three-dimensional VCA was measured, and the cutoff value and area under the curve (AUC) for the prediction of severe MR were estimated by receiver operating characteristic curve using a guideline-suggested multiparametric approach as the reference standard. In a subgroup of patients, 3D regurgitant volume (RV) and 3D fraction were calculated from mitral and left ventricular outflow tract stroke volumes to further validate 3D VCA against a 3D volumetric reference standard. RESULTS: The optimal 3D VCA cutoff value for predicting severe MR was 0.45 cm2 (specificity, 0.87; sensitivity, 0.90) with an AUC of 0.95 using a multiparametric approach as reference. Three-dimensional VCA had a good linear correlation with EROA-PISA (r = 0.62, P < .05) with larger values compared to EROA-PISA (0.63 cm2 vs 0.44 cm2, P < .05). A cutoff of 0.50 cm2 (AUC of 0.84; sensitivity, 0.78; specificity, 0.78) predicts an EROA-PISA of 0.40 cm2. Three-dimensional VCA had a good linear correlation with 3D RV (r = 0.56, P < .01), with an AUC of 0.86 to predict a 3D fraction >50%. CONCLUSIONS: The present study suggests 0.45 cm2 as the best cutoff value of 3D VCA to define severe MR in patients with MVP, showing an optimal agreement with the reference standard multiparametric approach and 3D RV.

Long-term Results of Clover and Edge-to-Edge Leaflet Repair for Complex Tricuspid Regurgitation.

BACKGROUND: The aim of this study was to report the long-term results of the clover and edge-to-edge repair techniques for complex tricuspid regurgitation (TR). METHODS: This was a single-center observational study. A competing risks proportional-hazards regression model, using the Fine and Gray model, was performed to analyze the time to TR ≥2+, considering death as a competing risk. RESULTS: A total of 145 consecutive patients (57% female) with severe or moderately severe TR secondary to leaflet prolapse or flail (115 patients), tethering (27 patients), or mixed (3 patients) lesions underwent clover (110 patients) or edge-to-edge repair(35 patients). The TR origin was degenerative in 75% of cases, posttraumatic in 8%, and secondary to dilated cardiomyopathy in 17%. Ring (64%) or suture (31%) annuloplasty was performed in 95% of patients. Concomitant procedures (mainly mitral surgery) were performed in 80% of cases. Hospital death was 5.5%. Follow-up was 98% complete, and median was 15 years (interquartile range, 14-17 years). The 16-year overall survival was 56% ± 5%. Previous cardiac surgery (hazard ratio [HR], 2.83; 95% CI, 1.15-6.93; P = .023) and right ventricular dysfunction (HR, 2.24; 95% CI, 1.01-4.95; P = .046) were identified as predictors of death. The 16-year cumulative incidence function (CIF) of cardiac death with noncardiac death as a competing risk was 19.6%, and previous cardiac surgery (HR, 3.44; 95% CI, 1.23-9.65; P = .019) was detected as the only predictor of the event. At 16 years, the CIF of TR ≥2+ with death as a competing risk was 23.8%. In particular, TR ≥3+ was detected in 4 patients (3%). CONCLUSIONS: When TR could not be treated by annuloplasty alone, concomitant leaflet repair with the clover or edge-to-edge technique effectively restored valve competence with very satisfactory long-term results and a low rate of moderate or greater TR recurrence.

Impact on Outcome of Different Mechanisms, Baseline Degree and Changes of Mitral Regurgitation in Patients With Aortic Stenosis Who Underwent Transcatheter Aortic Valve Replacement.

BACKGROUND: Mitral regurgitation (MR) is frequent in patients with aortic stenosis (AS). Although primary MR is an established negative prognostic factor, whether different mechanisms of MR have different effects on outcome is currently unknown. The aim of this study was to evaluate the impact of the MR mechanism in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: This is a retrospective observational study of patients who underwent TAVR for severe aortic stenosis in a high-volume tertiary care center. Echocardiographic comprehensive MR assessment was performed at baseline and within 3 months post TAVR. The study population was divided into 4 groups according to MR mechanism: Group I: fibro-calcific leaflet degeneration; Group II: prolapse/flail; Group III: ventricular secondary MR (functional MR); and Group IV: atrial functional MR. The study end point was a combination of death from cardiovascular cause and heart failure-related hospitalization. The study population included 427 patients (mean age 81.7±6.5 years; 71% primary MR; 62% ≥moderate MR). At 3-year follow-up, survival free from the composite end point significantly differs according to MR mechanism: it was higher in group IV (atrial functional MR, 96.6%) compared with group I (80.4%, P=0.002) and group II patients (60.7%, P=0.001), and group III (84.8%, P=0.037); patients with MR due to leaflet prolapse showed poorer prognosis compared with patients with functional MR (group III, P=0.023 and group IV, P=0.001) and with group I (P=0.040). Overall, severe MR after TAVR identified patients with poorer prognosis and was significantly more frequent in group II (46.4%, P=0.001). CONCLUSIONS: In patients undergoing TAVR, preprocedural identification of MR mechanism and mechanism provides prognostic insights.

Left atrial appendage occlusion after thromboembolic events or left atrial appendage sludge during anticoagulation therapy: Is two better than one? Real-world experience from a tertiary care hospital.

Background: The role of left atrial appendage occlusion (LAAO) for atrial fibrillation patients that during oral anticoagulant therapy (OAC) suffer from ischemic events or present LAA sludge, and the best postinterventional anticoagulant regimen, need to be defined. We present our experience with a hybrid approach of LAAO+ lifelong OAC therapy in this cohort of patients. Methods: Out of 425 patients treated with LAAO, 102 underwent LAAO because, despite OAC, suffered from ischemic events or presented with LAA sludge. Patients without high bleeding risk were discharged with the aim of maintaining lifelong OAC. This cohort was then matched to a population who underwent LAAO in primary ischemic events prevention. The primary endpoint was the composite of all-cause death and major adverse cardiovascular events consisting of ischemic stroke, systemic embolism (SE), and major bleeding. Results: Procedural success was 98%, and 70% of patients were discharged with anticoagulant therapy. After a median follow-up of 47.2 months, the primary endpoint occurred in 27 patients (26%). At multivariate analyses, coronary artery disease (OR 5.1, CI 1.89-14.27, p = .003) and OAC at discharge (OR 0.29, CI 0.11-0.80, p = .017) were associated with the primary endpoint. After propensity score matching, no significant difference was found in the survival free from the primary endpoint according to the indication for LAAO (p = .19). Conclusions: In this high-ischemic risk cohort, LAAO + OAC seem a long-term safe and effective therapeutical approach, with no difference in the survival free from the primary endpoint according to the indication for LAAO in a matched cohort.
