Efficacia e complicanze della “ross procedure”: importanza dell’esperienza dell’operatore

Lo studio presenta notevoli elementi di interesse. Da un lato la crescita degli interventi negli ultimi anni sottolinea i dati favorevoli di outcome associati alla procedura di Ross. La mortalità operatoria più bassa è stata osservata negli anni 2019/2020, quando i centri che effettuavano questo tipo di intervento erano meno di 30 (27 nel 2019 e 29 nel 2020) e la procedura di Ross rappresentava meno del 3% delle sostituzioni valvolari aortiche chirurgiche (112 procedure nel 2019, pari al 2.3% e 149 nel 2020, pari al 2.9%). A partire da quegli anni, un numero crescente di centri ha iniziato a effettuare tale intervento…

The year in cardiovascular medicine 2025: the top 10 papers in valvular heart disease

1. Poterucha TJ, Jing L, Ricart RP, et al. Detecting structural heart disease from electrocardiograms using AI. Nature 2025; 644:221–30. doi.org/10.1038/s41586-025-09227-0. We introduce a deep learning model, EchoNext, trained on more than 1 million heart rhythm and imaging records across a large and diverse health system to detect many forms of structural heart disease. These findings support the potential of artificial intelligence to expand access to heart disease screening at scale. To enable further development and transparency, we have publicly released model weights and a large, annotated dataset linking heart rhythm data to imaging-based diagnoses. 2. Long A, Finer J, Hartman H, et al. Deep learning for echocardiographic assessment and risk stratification of aortic, mitral, and tricuspid regurgitation: the DELINEATEregurgitation study. Eur Heart J 2025;46: 2780–91. Classification and risk stratification in aortic (AR), mitral (MR), and tricuspid regurgitation (TR) remains a significant clinical challenge. This study aimed to develop an artificial intelligence (AI) system to assess valvular regurgitation and stratify MR-progression risk. An AI system can accurately classify AR, MR, and TR and predict MR progression beyond currently known risk factors. 3. Généreux P, Banovic M, Kang D, et al. Aortic valve replacement vs clinical surveillance in asymptomatic severe aortic stenosis: a systematic review and meta-analysis. J Am Coll Cardiol 2025;85:912–22. doi.org/ 10.1016/j.jacc.2024.11.006.   Current guidelines recommend a strategy of clinical surveillance (CS) for patients with asymptomatic severe aortic stenosis (AS) and a normal left ventricular ejection fraction. In this meta-analysis of 4 randomized trials, early aortic valve replacement was associated with a significant reduction in unplanned cardiovascular or heart failure hospitalization and stroke and no differences in all-cause and cardiovascular mortality compared with CS. 4. Leon MB, Mack MJ, Pibarot P, et al. Transcatheter or surgical aortic-valve replacement in low-risk patients at 7 years. N Engl J Med 2025. doi.org/10.1056/NEJM oa2509766. Five-year data from the PARTNER 3 trial showed that among low-risk patients with severe, symptomatic aortic stenosis, outcomes were similar among patients who had undergone transcatheter aortic-valve replacement (TAVR) and those who had undergone surgical aortic-valve replacement. Longer-term assessments of clinical outcomes and valve durability are needed. Among low-risk patients with severe, symptomatic aortic stenosis, no significant differences with respect to two primary composite end points involving death, stroke, and rehospitalization were observed at 7 years between those who had undergone TAVR and those who had undergone surgery. 5. Jørgensen TH, Savontaus M, Willemen Y, et al. Three-year follow-up of the NOTION-2 trial: TAVR versus SAVR to treat younger low-risk patients with tricuspid or bicuspid aortic stenosis. Circulation 2025;152: 1326–37.   Transcatheter aortic valve replacement (TAVR) is increasingly performed in younger, low surgical risk patients. The NOTION-2 study (The Nordic Aortic Valve Intervention) reports midterm outcomes in low-risk patients age 60 to 75 years with severe tricuspid or bicuspid aortic stenosis undergoing TAVR or surgical valve replacement. For patients age 60 to 75 years with severe aortic stenosis who are at low surgical risk, 3-year clinical outcomes are similar between TAVR and surgery. Both procedures are associated with low rates of structural valve deterioration and need for reintervention. 6. Raposeiras-Roubin S, Amat-Santos IJ, Rossello X, et al. Dapagliflozin in patients undergoing transcatheter aortic-valve implantation. N Engl J Med 2025;392:1396–405. https://doi.org/10.1056/ NEJMoa2500366. Sodium–glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of heart-failure admission among high-risk patients. However, most patients with valvular heart disease, including those undergoing transcatheter aortic-valve implantation (TAVI), have been excluded from randomized trials. Among older adults with aortic stenosis undergoing TAVI who were at high risk for heart failure events, dapagliflozin resulted in a significantly lower incidence of death from any cause or worsening of heart failure than standard care alone.  7. Messika-Zeitoun D, Chu MWA, Bouchard D, et al. Clinical presentation and outcomes after surgery for mitral regurgitation: real- world insights from the MITRACURE international registry. Circulation 2025;152: 927–38.  Comprehensive knowledge of the clinical presentation, contemporary management, and outcomes on “all-comer” patients referred for mitral valve surgery (MVS) are critical to evaluate current practice and adherence to guidelines, understand selection biases, and inform key stakeholders on quality improvement. MITRACURE provides a contemporary, multicenter, “real-world” picture of the clinical presentation, management, and in-hospital outcomes of MVS for MR in two Western countries. Patients were often referred late in the disease process, with few patients undergoing early intervention. The higher mortality and lower repair rates reported may be more reflective of an unselected MR patient population but have room for improvement. Our results underline the need to develop strategies to improve management and outcomes of patients with MR.  8. Kaneko T, Kagiyama N, Okazaki S, et al.

Epub ahead of print. doi.org/10.1093/ eurheartj/ehaf511. Atrial functional mitral regurgitation (AFMR) commonly affects elderly and frail individuals. The prognostic impact of transcatheter edgeto-edge repair (TEER) for AFMR has not been. investigated. In real-world data, TEER for patients with moderate or severe AFMR were associated with a lower incidence of adverse events compared with medical treatment.  9.

Patients with severe mitral regurgitation are frequently not candidates for surgery or transcatheter edge-to-edge repair (TEER). We aimed to evaluate 1-year outcomes of a novel percutaneous transseptal transcatheter mitral valve replacement (TMVR) system in patients unsuitable for surgery or TEER. Percutaneous transseptal TMVR with the SAPIEN M3 system effectively reduced mitral regurgitation with low rates of complications and mortality. These findings support percutaneous TMVR with the SAPIEN M3 system as a therapeutic option for patients who are unsuitable for surgery or TEER. 10.

The year in cardiovascular medicine 2025: the top 10 papers in thrombosis and antithrombotic therapy

Inquadramento 1. Byrne RA, Valgimigli M, Bhatt DL, et al. Great debate: default duration of dual antiplatelet treatment after percutaneous coronary intervention in acute coronary syndrome should be 12 months. Eur Heart J 2025;46: 1965–78. doi.org/10.1093/ eurheartj/ehaf070. The evidence analysis summarized above provides a rationale as to why 12-month DAPT was maintained as the default strategy in preference to abbreviated durations of DAPT in patients with ACS.2 Given the conflicting evidence in the literature, Class II recommendations for DAPT abbreviation are appropriate. This approach is safer for patients than changing the default strategy to one that has not yet been adequately tested in higher-risk, more representative ACS populations. 2. Tarantini G, Honton B, Paradies V, et al. Early discontinuation of aspirin after PCI in low-risk acute myocardial infarction. N Engl J Med 2025;393:2083–94. An appropriate duration of dual antiplatelet therapy after percutaneous coronary intervention for acute myocardial infarction that has been treated with guidelinerecommended complete revascularization and a contemporary drug-eluting stent remains unclear. Among low-risk patients with acute myocardial infarction who had undergone early complete revascularization and had completed 1 month of dual antiplatelet therapy without complications, P2Y12-inhibitor monotherapy was noninferior to continued dual antiplatelet therapy with respect to the occurrence of adverse cardiovascular and cerebrovascular events and resulted in a lower incidence of bleeding events. 3. Guimaraes PO, Franken M, Tavares CAM, et al. Early withdrawal of aspirin after PCI in acute coronary syndromes. N Engl JMed 2025;393:2095–106. Whether potent P2Y12 inhibitor monotherapy without ASA initiated shortly after successful percutaneous coronary intervention (PCI) is effective and safe for patients with acute coronary syndromes is unclear. Among patients who had undergone successful PCI for acute coronary syndromes, potent P2Y12 inhibitor monotherapy was not found to be noninferior to dual antiplatelet therapy with respect to a composite of death or ischemic events at 12 months. 4. Jeppsson A, James S, Moller CH, Malm CJ, Dalén M, Vanky F, et al. Ticagrelor and aspirin or aspirin alone after coronary surgery for acute coronary syndrome. N Engl J Med 2025; 393:2313–23.   Patients benefit from antiplatelet therapy after coronary-artery bypass grafting (CABG) for an acute coronary syndrome. Whether the addition of ticagrelor to ASA, as compared with ASA alone, further reduces the risk of adverse cardiovascular outcomes is unclear. Among patients who underwent CABG for an acute coronary syndrome, ticagrelor plus ASA did not result in a lower incidence of death, myocardial infarction, stroke, or repeat coronary revascularization than ASA alone at 1 year. 5. Van’t Hof AWJ, Gibson CM, Rikken SAOF, et al. Zalunfiban at first medical contact for ST-elevation myocardial infarction. NEJM Evid 2025;5:EVIDoa2500268. Zalunfiban is a glycoprotein IIb/IIIa (integrin αIIbβ3) inhibitor designed for subcutaneous administration on first medical contact with patients with suspected ST-segment elevation myocardial infarction (STEMI). In patients with STEMI, zalunfiban administered at first medical contact significantly improved preintervention infarct-related patency and reduced the likelihood of a worse 30-day multicomponent hierarchical clinical end point. Zalunfiban was not associated with increased severe or life-threatening bleeding but was associated with increased mild to moderate bleeding. 6. Rashedi S, Keykhaei M, Sato A, et al. Anticoagulation and antiplatelet therapy for atrial fibrillation and stable coronary disease: meta-analysis of randomized trials. J Am Coll Cardiol 2025;85:1189–203.   The optimal long-term antithrombotic strategy in patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) remains uncertain. Individual randomized controlled trials (RCTs) had variations in their reported results and were not powered for effectiveness outcomes. In patients with AF and stable CAD, OAC monotherapy, compared with OAC plus SAPT, was not associated with a statistically significant increased risk of ischemic events but resulted in a significantly reduced risk of bleeding. 7. Lemesle G, Didier R, Steg PG, et al. Aspirin in patients with chronic coronary syndrome receiving oral anticoagulation. N Engl J Med 2025;393:1578–88. The appropriate antithrombotic regimen for patients with chronic coronary syndrome who are at high atherothrombotic risk and receiving long-term oral anticoagulation remains unknown. Among patients with chronic coronary syndrome at high atherothrombotic risk who were receiving an oral anticoagulant, the addition of ASA led to a higher risk of cardiovascular death, myocardial infarction, stroke, systemic embolism, coronary revascularization, or acute limb ischemia than placebo, as well as higher risks of death from any cause and major bleeding. 8. Lee SJ, Yu HT, Lee YJ, et al. Therapy for atrial fibrillation in patients with drug eluting stents. N Engl J Med 2025. https://doi.org/10.1056/NEJMoa2512091. Despite guideline recommendations, evidence for the use of non–vitamin K antagonist oral anticoagulant (NOAC) monotherapy in patients with atrial fibrillation after implantation of a drug-eluting stent remains limited. Among patients with atrial fibrillation who had undergone implantation of a drug-eluting stent at least 1 year earlier, NOAC monotherapy was noninferior to combination therapy for net adverse clinical events. 9. Joosten LPT, van Doorn S, van de Ven PM, et al. Safety of switching from a vitamin K antagonist to a non-vitamin K antagonist oral anticoagulant in frail older patients with atrial fibrillation: results of the FRAIL AF randomized controlled trial. Circulation 2024;149:279–89. https://doi.org/10.1161/ CIRCULATIONAHA.123.066485. There is ambiguity whether frail patients with atrial fibrillation managed with vitamin K antagonists (VKAs) should be switched to a non vitamin K oral anticoagulant (NOAC). Switching international normalized ratio–guided VKA treatment to an NOAC in frail older patients with atrial fibrillation was associated with more bleeding complications compared with continuing VKA treatment, without an associated reduction in thromboembolic complications. 10. Nicolau AM, Giugliano RP, Zimerman A, et al. Outcomes in older patients after switching to a newer anticoagulant or remaining on warfarin: the COMBINE-AF substudy. J Am Coll Cardiol 2025;86:426–39. Whether frail, elderly patients with atrial fibrillation (AF) on a vitamin K antagonist (VKA) should switch to a direct-acting oral anticoagulant (DOAC) was studied in the FRAIL-AF trial and remains controversial. Frail, elderly, VKA-experienced patients with AF switched to SD-DOAC experienced significant reductions in stroke or systemic embolism, fatal and intracranial bleeding, and death. Gastrointestinal bleeding was increased with SD-DOAC, while major bleeding and the primary net clinical outcome were similar.

Mortalità cardiovascolare e non cardiovascolare dopo sindrome coronarica acuta

Lo studio ha analizzato le cause di mortalità in 1.562.956 pazienti cinesi con una diagnosi di dimissione di ACS tra il gennaio 2018 e il dicembre 2021, i cui dati sono stati inseriti nel China Cardiovascular Association Database- Chest Pain Center. Oltre i due terzi erano di sesso maschile, l’età media era 63.8 anni, 39% erano STEMI, il 22% NSTEMI e il restante 39% rappresentato da angine instabili. Il 24% dei pazienti era diabetico, mentre i fumatori erano il 32%. L’analisi è stata effettuata utilizzando il  modello di Fine-Gray (Fine-Gray subdistribution hazard model) che tiene conto dei rischi competitivi nel computo della mortalità (cause CV versus cause non CV). Al termine del followup (dicembre 2021) 110.406 pazienti, pari al 7.1% della popolazione ACS era deceduto con una incidenza annua del 4.4%. Le cause CV rappresentavano il 73.5% dei decessi, mentre il restante 26.5% era costituito da…

 1. Tarantini G, Honton B, Paradies V, et al. Early discontinuation of aspirin after PCI in low-risk acute myocardial infarction. N Engl J Med 2025;393:2083–94. Among low-risk patients with acute myocardial infarction who had undergone early complete revascularization and had completed 1 month of dual antiplatelet therapy without complications, P2Y12-inhibitor monotherapy was noninferior to continued dual antiplatelet therapy with respect to the occurrence of adverse cardiovascular and cere- brovascular events and resulted in a lower incidence of bleeding events. 2. Guimarães PO, Franken M, Tavares CAM, et al. Early withdrawal of aspirin after PCI in acute coronary syndromes. N Engl J Med 2025;393:2095–106. Among patients who had undergone successful PCI for acute coronary syndromes, potent P2Y12 inhibitor monotherapy was not found to be noninferior to dual antiplatelet therapy with respect to a composite of death or ischemic events at 12 months. 3. Gould KL, Johnson NP, Roby AE, et al. Optimal medical care and coronary flow capacity-guided myocardial revascularization vs usual care for chronic coronary artery disease: the CENTURY trial. Eur Heart J 2025;46:3273–86. Erratum in: Eur Heart J. 2025 Sep 2;46(33):3286 . The randomized CENTURY trial demonstrates that comprehensive integrated lifestyle modification and medical management towards goals with revascularization reserved for severely reduced CFC, significantly reduced risk factor scores, death, death or MI, and revascularization. 4. Fearon WF, Zimmermann FM, Ding VY, et al. Outcomes after fractional flow reserve-guided percutaneous coronary intervention versus coronary artery bypass grafting (FAME 3): 5-year follow-up of a multicentre, open-label, randomised trial. Lancet 2025;405:1481–90. This prespecified 5-year follow-up of FAME 3 shows no significant differences in the composite outcome of death, stroke, or myocardial infarction in 1.500 patients with three-vessel CAD not involving the left main coronary artery, although rates of myocardial infarction and repeat revascularisation remained higher with PCI. In addition, this final analysis of the trial showed no longterm accrual of benefit after CABG on a composite outcome of death, stroke, or myocardial infarction, which contradicts previous studies. 5. Ali ZA, Shin D, Vijayvergiya R. et al. Optical coherence tomography -vs angiographyguided coronary stent implantation in calcified lesions: the ILUMIEN IV trial.  Eur Heart J 2025;46:3201–10. In the ILUMIEN IV trial, OCT-guided PCI in patients with angiographically determined moderately or severely calcified lesions reduced the 2-year rate of target vessel failure compared with angiography-guided PCI, an effect that was not seen in patients with lesions with no or mild angiographic calcium.  6.

Lancet 2025;406:1032–43. Among patients with STEMI and multivessel disease, immediate complete revascularisation was not shown to be noninferior to staged complete revascularisation during the index admission in terms of incidence of a composite of death from any cause, non-fatal myocardial infarction, or any unplanned revascularisation at 1 year. This finding might inform future clinical guidelines on the role and optimal use of immediate complete revascularisation during the index admission. 7. Nijveldt R, Maeng M, Beijnink CWH, et al.

Quale strategia antitrombotica utilizzare dopo impianto di dispositivo di chiusura dell’auricola?

La chiusura percutanea dell’auricola sinistra (left atrial appendage closure, LAAC) rappresenta una strategia consolidata per la prevenzione degli eventi tromboembolici nei pazienti con fibrillazione atriale non valvolare e controindicazione alla terapia anticoagulante orale a lungo termine. . Nonostante l’efficacia della procedura, la gestione antitrombotica nella fase precoce rimane uno dei problemi più complessi: il dispositivo non è ancora completamente endotelizzato e il rischio di trombosi correlata al device (device-related thrombosis, DRT) rimane clinicamente rilevante. La DRT è una complicanza infrequente ma non…
