RESUMEN
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.

OBJECTIVES: To identify a simple echocardiographic predictor of procedural success to select patient for percutaneous suture-mediated patent fossa ovalis (PFO) closure. BACKGROUND: Percutaneous suture-mediated PFO closure has been shown as a safe and advantageous alternative to device-based PFO closure, yet its overall success is slightly lower in unselected patients. METHODS: Preprocedural transesophageal echocardiogram (TEE) of 302 patients (113 men, 45 ± 12 years) who underwent percutaneous suture-mediated PFO closure were reviewed. RESULTS: At echocardiographic follow-up (3-6 months), residual right-to-left shunt (RLS) ≥2 was found in 60 (19.9%) patients. At multivariable analysis, only two anatomical variables measured at preprocedural TEE were found as independent predictors of residual RLS ≥ 2 at follow-up: PFO maximum width (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.16-3.40, p = 0.02) and PFO minimal septa overlapping (OR 0.58, 95% CI 0.35-0.88, p = 0.02). An index based on the ratio of PFO maximum width to PFO minimum septal overlapping (W/SO) proved to be the most powerful predictor of RLS ≥ 2 at follow-up (OR 48.1, 95% CI 9.3-352.2, p < 0.01). The ROC curve for the W/SO ratio was found to have an AUC of 0.84 (95% CI 0.75-0.93) and a cut-off value of 0.61 yielding a sensitivity of 80% and specificity of 78% with a negative predictive value of 94%. A decision tree methodology's AUC was 0.75 (95% CI 0.67-0.83). CONCLUSIONS: The results of this study indicate that the ratio between the maximum amplitude of the PFO and the minimum overlap of the septa is the best predictive index of a favorable result by using one stitch only.

AIMS: Pulmonary vein (PV) antrum isolation proved to be effective for treating persistent atrial fibrillation (PeAF). We sought to investigate the results of a personalized approach aimed at adapting the ablation index (AI) to the local left atrial wall thickness (LAWT) in a cohort of consecutive patients with PeAF. METHODS AND RESULTS: Consecutive patients referred for PeAF first ablation were prospectively enrolled. The LAWT three-dimensional maps were obtained from pre-procedure multidetector computed tomography and integrated into the navigation system. Ablation index was titrated according to the local LAWT, and the ablation line was personalized to avoid the thickest regions while encircling the PV antrum. A total of 121 patients (69.4% male, age 64.5 ± 9.5 years) were included. Procedure time was 57â min (IQR 50-67), fluoroscopy time was 43â s (IQR 20-71), and radiofrequency (RF) time was 16.5â min (IQR 14.3-18.4). The median AI tailored to the local LAWT was 387 (IQR 360-410) for the anterior wall and 335 (IQR 300-375) for the posterior wall. First-pass PV antrum isolation was obtained in 103 (85%) of the right PVs and 103 (85%) of the left PVs. Median LAWT values were higher for PVs without first-pass isolation as compared to the whole cohort (P = 0.02 for left PVs and P = 0.03 for right PVs). Recurrence-free survival was 79% at 12 month follow-up. CONCLUSION: In this prospective study, LAWT-guided PV antrum isolation for PeAF was effective and efficient, requiring low procedure, fluoroscopy, and RF time. A randomized trial comparing the LAWT-guided ablation with the standard of practice is in progress (ClinicalTrials.gov, NCT05396534).

Renal denervation (RDN) is a therapeutic strategy for patients with uncontrolled arterial hypertension characterized by considerable fluctuations during its progression. After initial strong enthusiasm, the procedure came to an abrupt halt following the publication of the Symplicity HTN-3 study results. The results of recently published studies highlight the reduction in blood pressure values after RDN and justify the inclusion in the Guidelines of new recommendations for the use of RDN in clinical practice, in selected patients. Additionally, RDN findings are summarized in view of other potential indications such as atrial fibrillation. Six prospective, randomized studies are presented that evaluated RDN as an adjunct therapy to pulmonary vein isolation for the treatment of atrial fibrillation. In five studies, patients had uncontrolled hypertension despite therapy with three antihypertensive drugs. The analysis of these studies showed that RDN reduced the recurrence of atrial fibrillation (AF) by 57% compared to patients with pulmonary vein isolation (PVI) only. Modulation of the autonomic nervous system by RDN has been shown not only to reduce blood pressure but also to have an antiarrhythmic effect in symptomatic AF patients when the strategy is combined with PVI, thus opening up new therapeutic scenarios.
RESUMEN
OBJECTIVES: Coronavirus disease 2019 (COVID-19) is a viral illness caused by severe acute respiratory syndrome coronavirus 2. With the increasing number of improved and discharged patients with COVID-19, the definition of an adequate follow-up strategy is needed. The purpose of this study was to assess whether lung ultrasound (LUS) is an effective indicator of subclinical residual lung damage in patients with COVID-19 who meet discharge criteria. METHODS: We prospectively enrolled 70 consecutive patients with COVID-19 who had a prolonged hospitalization with inpatient rehabilitation between April 6 and May 22, 2020. All of the patients underwent an LUS evaluation at discharge. Data of patients with more severe disease during the acute phase (ie, required ventilatory support) were compared to those of patients with milder disease. RESULTS: Among the 70 patients with COVID-19 (22 women and 48 men; mean age ± SD, 68 ± 13 years), the LUS score before discharge was still frankly pathologic and higher in patients who had more severe disease during the acute phase compared to patients with milder disease (median [interquartile range], 8.0 [5.5-13.5] versus 2.0 [1.0-7.0]; P < .001), even when both categories met internationally defined discharge criteria. CONCLUSIONS: Lung ultrasound can identify the persistence of subclinical residual lung damage in patients with severe COVID-19 even if they meet discharge criteria. Considering the low cost, easy application, and lack of radiation exposure, LUS seems the ideal tool to be adopted in outpatient and primary care settings for the follow-up of patients with COVID-19.

Aims: Suture-mediated patent fossa ovalis (PFO) closure is a recent technique, achieving closure by means of a simple suture. The differences between traditional occluders and suture might have different impacts on atrial function. The aim of this study was to evaluate atrial function after PFO closure by direct suture and traditional occluders. Methods and results: We prospectively studied 40 patients, 20 undergoing PFO closure by occluder and 20 by suture. Trans-thoracic echocardiography was carried out the day before and 1 year after the procedure. Left atrial (LA) and right atrial (RA) function was evaluated by using speckle-tracking analysis assessing the strain values of the reservoir (st-RES), conduit (st-CD), and contraction phase (st-CT). Compared with values baseline PFO closure, at 1-year follow-up, patients with occluder implantation had significantly worse indices of LA and RA reservoir (LA st-RES P < 0.001; RA st-RES P < 0.001), conduit (LA st-CD P < 0.001; RA st-CD P < 0.001), and contraction function (LA st-CT P < 0.05; RA st-CT P < 0.05). In patients with suture-mediated PFO closure, no significant differences were observed in the same indices of reservoir (LA st-RES P = 0.848; RA st-RES P = 0.183), conduit (LA st-CD P = 0.156; RA st-CD P = 0.419), and contraction function (LA st-CT P = 0.193; RA st-CT P = 0.375). Conclusion: Suture-mediated PFO closure does not alter atrial function. Conversely, PFO closure by metallic occluders is associated with a deterioration of atrial function. This detrimental effect on atrial function could favour the development of atrial arrhythmias.
RESUMEN
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.

BACKGROUND: In patients with atrial fibrillation (AF) on vitamin K antagonist (VKA) therapy and therapeutic international normalized ratio (INR) range, the incidence of cardiac thromboembolism is not negligible, and the subgroup of patients who have a mechanical prosthetic mitral valve (PMV) has the highest risk. We aimed to assess the long-term effects of left atrial appendage closure (LAAC) in AF patients with a mechanical PMV who experienced a failure of VKA therapy. METHODS: In this retrospective, multicentre study, patients underwent LAAC because of thrombotic events including transient ischemic attack and/or stroke, systemic embolism, and evidence of left atrial appendage thrombosis and/or sludge, despite VKA therapy, were enrolled. Patients with a mechanical PMV were included and compared with those affected by nonvalvular AF. The primary endpoint was the composite of all-cause death, major cardiovascular events, and major bleedings at follow-up. The feasibility and safety of LAAC also were assessed. RESULTS: A total of 55 patients (42% female; mean age, 70 ± 9 years), including 12 with a mechanical PMV, were enrolled. The most-frequent indication to LAAC (71%) was LAA thrombosis or sludge. Procedural success was achieved in 96% of overall cases, and in 100% of patients with a PMV. In 35 patients, a cerebral protection device was used. During a median follow-up of 6.1 ± 4.3 years, 4 patients with a PMV, and 20 patients without a PMV, reported adverse events (hazard ratio 0.73 [95% confidence interval 0.25-2.16, P = 0.564]). CONCLUSIONS: LAAC seems to be a valuable alternative in patients with AF who have a mechanical PMV, with failure of VKA therapy. This off-label, real-world clinical practice indication deserves validation in further studies.
RESUMEN
BACKGROUND: Atrial fibrillation is an undesirable event following percutaneous patent fossa ovalis (PFO) closure with metallic occluders, suggesting that implanting a rigid closure device could alter atrial function. Suture-mediated PFO closure is a new technique, achieving closure of the PFO by means of a simple suture. Aim of this study was to evaluate left atrial function after closure of PFO by direct suture and traditional occluders. METHODS: We studied 40 age and sex homogeneous patients, 20 undergoing PFO closure by device (OCL) and 20 by suturing (NS). Twenty healthy sex-age matched subjects made up the control group (CT). Left atrial function was evaluated by using volumetric and speckle-tracking analysis assessing the following parameters: total emptying fraction (EF), Expansion Index (EI), active emptying fraction (AEF), strain values of the reservoir (r-ED), conduit (cd-ED) and contraction phase (ct-ED). RESULTS: Compared to CT and NS, OCL patients had significantly worst indices of left atrial reservoir function (EF P=0.001, EI P=0.003, r-ED P<0.001), conduit function (cd-ED P=0.018) and contraction function (AEF P=0.010; ct-ED P<0.001). No significant differences were observed in left atrial function indices between CT and NS patients. CONCLUSIONS: Suture-mediated PFO closure does not alter left atrial function. Conversely, metallic occluder is associated with worse left atrium function. This detrimental effect on atrial function could favor the development of atrial arrhythmias.

BACKGROUND: Contrast-enhanced computed tomography is the reference-standard imaging technique to assess left atrial appendage (LAA) morphology. The aim of this study was to evaluate the accuracy and reliability of two-dimensional and new three-dimensional (3D) transesophageal echocardiographic rendering modalities in assessing LAA morphology. METHODS: Seventy consecutive patients who underwent both computed tomography and transesophageal echocardiography (TEE) were retrospectively enrolled. The traditional LAA morphology classification system (LAAcs; chicken wing, cauliflower, cactus, and windsock) and a new simplified LAAcs based on the LAA bend angle were used for the analysis. LAA morphology was independently assessed by two trained readers using three different modalities: two-dimensional TEE, 3D TEE with multiplanar reconstruction, and a new 3D transesophageal echocardiographic rendering modality with improved transparency (Glass). The new LAAcs and traditional LAAcs were compared in terms of intra- and interrater reliability. RESULTS: With the new LAAcs, two-dimensional TEE was fairly accurate in identifying LAA morphology (κ = 0.43, P < .05), with moderate interrater (κ = 0.50, P < .05) and substantial intrarater (κ = 0.65, P < .005) agreement. Three-dimensional TEE showed higher accuracy and reliability: 3D TEE with multiplanar reconstruction had almost perfect accuracy (κ = 0.85, P < .001) and substantial (κ = 0.79, P < .001) interrater reliability, while 3D TEE with Glass had substantial accuracy (κ = 0.70, P < .001) and almost perfect (κ = 0.84, P < .001) interrater reliability. Intrarater agreement was almost perfect for both 3D transesophageal echocardiographic modalities (κ = 0.85, P < .001). Accuracy was considerably lower when the traditional LAAcs was used, with 3D TEE with Glass being the most reliable technique (κ = 0.75, P < .05). The new LAAcs showed higher inter- and intrarater reliability compared with the traditional LAAcs (interrater, κ = 0.85 vs κ = 0.49; intrarater, κ = 0.94 vs κ = 0.68; P < .05). CONCLUSIONS: Three-dimensional TEE is an accurate, reliable, and feasible alternative to computed tomography in assessing LAA morphology with the new LAAcs. The new LAAcs shows higher reliability rates than the traditional one.

In patients with mild to moderate dementia, acetylcholinesterase inhibitors (AChE-I) are used to improve cognitive functions, but bradycardia, conduction abnormalities, and hypotension are possible side effects because of the peripheral muscarinic M2 receptor stimulation. This study aimed to evaluate the main cardiologic clinical outcomes in patients with dementia who are on AChE-I. In this retrospective, monocentric, observational cohort study, 2 groups were considered: (1) patients with dementia because of the typical and atypical forms of Alzheimer disease treated with AChE-I and (2) cognitively unimpaired, matched control group. The primary end point was a composite of cardiovascular death, nonfatal acute myocardial infarction, myocardial revascularization, occurrence of stroke and/or transient ischemic attacks, and hospitalization for heart failure occurring during a mean of 3.1 years of follow-up. The secondary end points were each individual component of the primary end point, total mortality, noncardiovascular death, and incidence of pacemaker implant. Each group included 221 patients who were homogeneous in terms of age, gender, and main cardiovascular risk factors. Major adverse cardiovascular events occurred in 24 patients with dementia (2.1 per 100 patient-years) compared with 56 in control group (5.0 per 100 patient-years), p = 0.036. Even if not significant, the difference was mainly driven by myocardial revascularization (3.2% vs 6.8%) and hospitalization for heart failure (4.5% vs 14.5%). As expected, noncardiovascular mortality was significantly higher in the treatment group (13.6% vs 2.7% p = 0.006). No significant difference between the groups was observed in terms of other secondary outcomes. In conclusion, in patients with dementia, the use of AChE-I may be protective for cardiovascular outcomes, especially in reducing heart failure hospitalization and myocardial revascularization.

BACKGROUND AND AIM: Measurement of cardiac index (CI) is crucial in the hemodynamic assessment of critically ill patients in the intensive care unit (ICU). The most reliable trans-thoracic echocardiography (TTE) technique for CI estimation is the left ventricular outflow tract (LVOT) Doppler method that requires, among other parameters, the LVOT cross-sectional area (CSA) measurement. However, inherent and practical disadvantages, mostly related to the ICU setting, hamper LVOT-CSA assessment. In this study, we aimed to validate a simplified formula, leveraging on LVOT-velocity time integral (VTI) and heart rate (HR) only, for non-invasive estimation of CI in ICU patients. METHODS AND RESULTS: We prospectively enrolled 50 consecutive patients admitted to our ICU requiring pulmonary artery catheterization (PAC) over a one-year period. For each patient we measured the CI by PAC (CIPAC) and TTE. The latter was obtained both with the "traditional formula" (traditional CITTE), requiring LVOT-CSA assessment, and our new "simplified formula" (simplified CITTE). The correlation between the simplified CITTE and CIPAC was strong (r = 0.81) and resulted significantly greater than the traditional CITTE and CIPAC correlation (r = 0.70; p < 0.05 for Pearson r coefficients comparison). Both TTE-based CI showed an acceptable agreement (+0.19 ± 0.48 L/min/m2 for simplified CITTE and - 0.18 ± 0.58 L/min/m2 for traditional CITTE) with the reference CIPAC. CONCLUSION: In this study, we validated a practical approach, leveraging on TTE LVOT-VTI and HR only, for non-invasive estimation of CI in ICU patients.

BACKGROUND AND IMPORTANCE: Chest pain is a frequent cause of patient admissions in emergency departments (EDs). Clinical scores can help in the management of chest pain patients with an undefined impact on the appropriateness of hospitalization or discharge when compared to usual care. OBJECTIVES: The aim of this study was to assess the performances of the HEART score to predict the 6-month prognostic of patients presenting to the ED of a tertiary referral university hospital with non-traumatic chest pain. DESIGN, SETTINGS, AND PARTICIPANTS: From 7040 patients presenting with chest pain from 1 January 2015 to 31 December 2017, after applying exclusion criteria (ST-segment elevation >1â mm, shock, absence of telephone number) we selected a sample of 20% chosen randomly. We retrospectively assessed the clinical course, definitive diagnosis, and HEART score according to ED final report. Follow-up was made by telephone interview with discharged patients. In hospitalized patients, clinical records were analyzed to evaluate major adverse cardiac events (MACE) incidence. OUTCOME MEASURE AND ANALYSIS: The primary endpoint was MACE, comprising cardiovascular death, myocardial infarction, or unscheduled revascularization at 6â months. We assessed the diagnostic performance of the HEART score in ruling out MACE at 6â months. We also assessed the performance of ED usual care in the management of chest pain patients. RESULTS: Of 1119 screened, 1099 were included for analysis after excluding patients lost to follow-up; 788 patients (71.70%) had been discharged and 311 (28.30%) were hospitalized. Incident MACE was 18.3% ( n â =â 205). The HEART score was retrospectively calculated in 1047 patients showing increasing MACE incidence according to risk category (0.98% for low risk, 38.02% for intermediate risk, and 62.21% for high risk). Low-risk category allowed to safely exclude MACE at 6â months with a negative predictive value (NPV) of 99%. Usual care diagnostic performance showed 97.38% sensitivity, 98.24% specificity, 95.5% positive predictive value, and 99% NPV, with an overall accuracy of 98.00%. CONCLUSIONS: In ED patients with chest pain, a low HEART score is associated with a very low risk of MACE at 6â months.

BACKGROUND: Percutaneous suture-mediated patent foramen ovale (PFO) closure has been recently introduced in clinical practice showing a favorable efficacy and safety profile in most PFO cases. The aim of this study was to assess the long-term outcomes of PFO closure by direct suture in a large consecutive series of patients. METHODS: We extracted all consecutive patients who underwent percutaneous closure of the PFO by suture technique (HeartStitch, Fountain Valley, CA, USA) from June 2016 with a follow-up of at least 2 years. After PFO closure, patients were followed-up clinically at 1, 6 and up to 12 months and microbubble transthoracic echocardiography (TTE) scheduled between 3 and 6 months, and at 12-month follow-up. After 12 months, patients were clinically checked every 6 months. RESULTS: As of September 1, 2020, 187 patients had undergone PFO closure with suture for at least two years and, of these, 181 (121 women and 60 men, mean age 45±13 years, range 15-75 years) had complete clinical and instrumental follow-up (97%). There were no peri-procedural complications. Mean follow-up was 1076±251 days (range 727-1574). At 12-month TTE, a significant residual atrial shunt was found in 39 patients (21%). At follow-up no recurrent thromboembolic or cerebral event occurred, no instrumental evidence of suture dehiscence detected and, 18 months after the procedure, one patient had an episode of transient atrial fibrillation lasting less than 24 hours and resolved spontaneously. CONCLUSIONS: Long-term follow-up data indicate that PFO closure by direct suturing is safe and effective. Two years after the procedure, there were no significant complications, no permanent arrhythmic complications and evidence of suture dehiscence.

Direct oral anticoagulants (DOACs) represent the cornerstone therapy for cardioembolic events prevention in patients with nonvalvular atrial fibrillation (NVAF). In practice, the choice of one DOAC over another is guided by the decision-making process of the physician, which considers specific patient and drug characteristics. This study aimed to evaluate the clinical features and long-term outcomes of a real-world population treated with DOACs, where the use of the 4 different DOACs is quite equal. We conducted a retrospective observational, single-center, multidisciplinary study enrolling consecutive NVAF patients treated with one of the 4 DOACs. From an initial number of 753 patients, we excluded 72 patients because of loss to follow-up, at the end we enrolled 681:174 (23%) treated with dabigatran, 175 (23%) with apixaban, 190 (25%) with rivaroxaban, and 214 (29%) with edoxaban. Patients treated with apixaban were significantly older, more women represented (p <0.001), and with a higher cardioembolic and bleeding risk (p <0.001). Dabigatran was preferred in patients with liver failure (p = 0.008), whereas Apixaban and Edoxaban were chosen in chronic kidney disease (p = 0.002). At 3-year follow-up, 20 patients (2.7%) experienced a systemic thromboembolic event without significant differences in the 4 DOACs. In the same period, an International Society of Thrombosis and Hemostasis classification major bleeding event occurred in 26 patients (3.6%), more statistically correlated to edoxaban (6.1%) (p = 0.038). Thromboembolic events or major bleeding were higher in the edoxaban group (10%) compared with the others (p = 0.014). In our single-center real-world experience, the choice of the DOAC for a patient with NVAF was tailored to specific clinical features and drug pharmacokinetics of the patient. As a result, a small number of adverse events were observed.

BACKGROUND: Patients with non-valvular atrial fibrillation (nvAF) who experienced a cardioembolic (CE) event despite adequate oral anticoagulation (OAC) are at high risk of recurrence, and further prevention strategies are deemed necessary. The present study aimed to evaluate the safety and efficacy of off-label use of left atrial appendage closure (LAAC) in this subset of patients. METHODS: Seventy-five consecutive patients with nvAF who experienced a CE event despite adequate OAC therapy were retrospectively enrolled from two Italian centers. Patients were divided according to the treatment strategy following the index event: DOAC group (49 patients who continued OAC therapy with DOACs) and LAAC group (26 patients who underwent LAAC procedure). 1:1 propensity-score matching between the two groups was performed. LAAC group was made up of two subgroups according to the post-procedural pharmacological regimen: 1) dual antiplatelet therapy (DAPT) for 3 months followed by indefinite single antiplatelet therapy (LAAC+SAPT); or 2) aspirin plus DOAC for 3 months followed by indefinite DOAC therapy (LAAC+DOAC). The primary endpoint was a composite of CE event, major bleeding, or procedure-related major complication. RESULTS: During a median follow-up of 3.4 years (IQR: 2.0-5.3), LAAC was a predictor of primary endpoint-free survival (HR=0.28, 95% CI: 0.08-0.97; P=0.044); within LAAC group, no procedure-related major complication occurred. Moreover, a trend toward a lower rate of both CE events and major bleedings was observed in LAAC group, particularly in the subgroup LAAC+DOAC. CONCLUSIONS: LAAC is a reasonable therapeutic option in nvAF patients who suffered a CE event despite adequate OAC therapy.

BACKGROUND: LAAO is an emerging option for thromboembolic event prevention in patients with NVAF. We previously reported data on comparison between LAAO and DOAC at two-year follow-up in NVAF patients at HBR (HAS-BLED ≥3). AIMS: Limited data are available on long term follow-up. We aimed to evaluate the efficacy and safety of DOACs versus LAAO indication after 5 years. METHODS: We enrolled 193 HBR treated with LAAO and 189 HBR patients with DOACs. At baseline, LAAO group had higher HAS-BLED (4.2 vs 3.3, p < 0.001) and lower CHADS-VASc (4.3 vs. 4.7, p = 0.005). After 1:1 PSM, 192 patients were included (LAAO n = 96; DOACs n = 96). RESULTS: At 5-year follow-up the rate of the combined safety and effectiveness endpoint (ISTH major bleeding and thromboembolic events) was significantly higher in LAAO group (p = 0.042), driven by a higher number of thromboembolic events (p = 0.047). The rate of ISTH-major bleeding events was similar (p = 0.221). After PSM no significant difference in the primary effectiveness (LAAO 13.3% vs DOACs 9.5%, p = 0.357) and safety endpoint (LAAO 7.5% vs DOACs 7.5%; p = 0.918) were evident. Overall bleeding rate was significantly higher in DOACs group (25.0% vs 13.7%, p = 0.048), while a non-significant higher number of TIA was reported in LAAO group (5.4% vs 1.1%, p = 0.098). All-cause and cardiovascular mortality were higher in LAAO group at both unmatched and matched analysis. CONCLUSION: We confirmed safety and effectiveness of both DOAC and LAAO in NVAF patients at HBR, with no significant differences in thromboembolic events or major bleeding were at 5-year follow-up. The observed increased mortality after LAAO warrants further investigations in RCTs.

Type 2 diabetes mellitus (DM) is constantly increasing worldwide and its most critical determinant of morbidity and mortality is still represented by cardiovascular (CV) complications. For years, cardiologists' approach to diabetic patients has been focused on risk factors optimization, with positive results. However, the management of DM per se was never truly considered in order to obtain prevention from major CV events, because medications used for glycemic control were not expected to gain CV benefit. Early trials concerning intensive versus conventional glycemia control did not prove useful in reducing the number of CV events. The introduction of new molecules led to a game change in DM treatment, as some new glucose-lowering drugs (GLDs), such as sodium-glucose linked transporter-2 inhibitors (SGLT-2i) and glucagon-like peptide 1 receptor agonists (GLP-1 RA), showed not only to be safe but also to ensure CV benefit. A combination of anti-atherogenic effects and hemodynamic improvements are likely explanations of the observed reduction of CV events and mortality. These evidence opened a completely new era in the field of GLDs and of DM treatment. Nonetheless, the presence of residual cardiovascular risk despite optimal medical therapy remains an issue and an aggressive strategy against multiple risk factors is suggested. A paradigm shift toward a new approach to DM management should be made with no further delay with the use of medications that may prevent CV events in an integrated strategy of CV risk reduction.

OBJECTIVES: This study sought to assess patent fossa ovalis (PFO) anatomy by transesophageal echocardiography (TEE) in patients undergoing percutaneous suture-mediated PFO closure to identify predictors of post-procedural residual atrial right-to-left shunt (RLS). BACKGROUND: Percutaneous suture-mediated PFO closure has been proven to be a safe and effective technique in most PFO patients. METHODS: From June 2016 to October 2019, 247 consecutive patients underwent percutaneous suture-mediated PFO closure at our institution. Of them, 230 (46 ± 13 years of age, 146 women) had complete and technically evaluable pre-procedural TEE. The following parameters in short-axis view were assessed: presence and grade of spontaneous RLS, PFO length and width, presence of atrial septal aneurysm and its maximal bulge, and presence of an embryonic or fetal remnant (Chiari network or Eustachian valve). RESULTS: At the first follow-up transthoracic echocardiography performed between 3 and 6 months from the closure procedure, a residual RLS ≥2 grade was found in 37 (16%) patients. Grade of pre-procedural spontaneous RLS (hazard ratio: 1.99; 95% confidence interval: 1.14 to 3.48; p = 0.016) shunt and PFO width (hazard ratio: 2.52; 95% confidence interval: 1.85 to 3.43; p < 0.001) were both found to be significantly associated with significant residual RLS at multivariable analysis. The presence of atrial septal aneurysm and its maximal bulge and of congenital remnants was not associated with significant residual RLS. CONCLUSIONS: Percutaneous suture-mediated PFO closure is feasible in the majority of septal anatomies; however, PFO >5 mm in width and spontaneous large RLS are less likely to be closed with 1 stitch only.
