Introduction 5-year survival of patients with ULM (Unprotected Left Main) stenosis according to the choice of revascularization (percutaneous vs. surgical) remains to be defined. Methods and results Randomized Controlled Trials (RTCs) comparing Percutaneous Coronary Intervention (PCI) vs. Coronary Artery Bypass Graft (CABG) with a follow-up of at least 5 years were included. All-cause death was the primary endpoint. MACCE (a composite endpoint of all-cause mortality, myocardial infarction [MI], stroke and repeat revascularization) along with its single components and cardiovascular (CV) death were the secondary ones. Analyses were stratified according to use of first vs. last generation coronary stents. Subgroup comparisons were performed according to Syntax Score (below or above 33) and to age (using cutoffs of each trial's subgroup analysis). 4 RCTs with 4394 patients were identified: 2197 were treated with CABG, 657 with first generation and 1540 with last generation stents. At 5 years rates of all-cause death did not differ (OR 0.93: 0.71–1.21), as those of CV death and stroke. CABG reduced rates of MACCE (OR 0.69: 0.60–0.79), mainly driven by MI (OR 0.48: 0.36–0.65) and revascularization (OR 0.53: 0.45–0.64). Benefit of CABG for MACCE was consistent, although with different extent, across values of Syntax Score (OR 0.76: 0.59–0.97 for values Conclusion For patients with ULM disease, PCI and CABG yielded same survival benefit at 5 years. CABG reduced risk of MI, revascularization and MACCE especially in older patients and in those with diffuse coronary disease. Funding Acknowledgement Type of funding source: None

Introduction Prognosis in pulmonary hypertension (PH) is strictly linked to right ventricle (RV) failure, which results from uncoupling between RV and the superimposed pressure load; in first phases, coupling between these two actors still be preserved, at the price of augmented right ventricle wall tension (RVWT). Purpose We sought to describe how to estimate RVWT with echocardiography, how it correlates with RV hemodynamics and if it may predict prognosis. Methods A total of 190 patients without overt RV failure, with suspected pulmonary hypertension (PH) to a previous echocardiography, underwent to right heart catheterization (RHC) and nearly-simultaneous echocardiography. We estimated RVWT according to Laplace law (RV length × tricuspid regurgitation peak gradient [TRPG]), in order to predict initial RV stress, and was correlated with RV hemodynamic profile; its potential prognostic impact was tested along with canonical RV function parameters. Results In patients enrolled in our study, RVWT correlated significantly with invasive estimation of right ventricle end diastolic pressure (R 0.343, p Correlation: RWVT and RV hemodynamic Hemodynamic variable R R2 p value Mean pulmonary artery pressure 0.742 0.550 Prognosis: different RV variables Discussion We identified a novel bedside echocardiographic predictor of altered RV hemodynamic, which results precociously altered in patients without overt RV failure, and able to predict all cause mortality at a long term follow up. Further studies are needed to confirm its role in PH patients.

Background The optimal antithrombotic therapy strategy in patients undergoing PCI who need OAC is currently debated. Purpose To determine the best regimen in terms of safety and efficacy. Methods We performed a meta-analysis of RCT and adjusted results reporting outcomes of patients who underwent PCI and were on TT or DAPT or DT. All-cause death was the primary end point, while MACE was the secondary outcome, along with its individual components, and major bleedings. Results 15 studies encompassing 27070 patients were included. After a follow up of 12 (11–14) months, TT reduced all-cause death compared to DAPT (OR 0.52, 0.35–0.78), mainly driven by a lower incidence of MI (OR 0.81, 0.69–0.85) and stroke (OR 0.76, 0.56–1.03) despite higher rates of major bleedings (OR 2.81, 1.54–5.12). Comparing TT vs. DT with warfarin, all-cause death was non-significantly different (OR 1.23, 0.60–2.53), nor MI (OR 0.77, 0.23–2.59) and stroke (OR 4.01, 0.80–20.07), while major bleeding was increased with TT (OR 2.40, 1.34–4.38). When compared to DT with NOACs, TT did not reduce risk of MI (OR 0.96, 0.67–1.36) or stroke (OR 0.82, 0.55–1.24), but increased major bleedings (OR 1.98, 1.43–2.73). The non-randomized comparison between DT with warfarin and DT with NOACs showed a neutral effect on death and major bleedings, with similar rates also of MI (OR 0.47, 0.20–1.11, all CI 95%). Conclusion Double therapy with warfarin or with NOAC plus a single antiplatelet agent reduces the risk of major bleeding compared to triple therapy, with a neutral impact of subsequent ischemic events.
