BACKGROUND: The staging classification of aortic stenosis (AS) which characterises the extent of cardiac damage has been validated in patients undergoing transcatheter aortic valve implantation (TAVI). Short-term changes in cardiac damage after TAVI and their association with long-term prognosis remain unknown. AIMS: This study aims to investigate the early evolution of cardiac damage after TAVI and the association of residual cardiac damage with clinical outcomes in TAVI recipients...

BACKGROUND: Atrial fibrillation (AF) associated with postoperative pericardial effusion is the most commonly reported adverse event after cardiac surgery. AIMS: We aimed to determine the role of posterior pericardiotomy in preventing postoperative AF (POAF). METHODS: We searched PubMed, Scopus, Web of Science, Ovid, and EBSCO from inception until 30 June 2022. We included randomised clinical trials (RCTs) that compared posterior pericardiotomy (PP) versus control (no PP) in patients undergoing cardiac surgery...

BACKGROUND: The Navitor transcatheter heart valve (THV) is a self-expanding valve, with an intra-annular leaflet position and an outer cuff intended to reduce paravalvular leak (PVL). AIMS: The aim of the PORTICO NG Study is to assess the safety and performance of the Navitor THV in patients with symptomatic, severe aortic stenosis who are at high or extreme surgical risk. METHODS: PORTICO NG is a prospective, multicentre, global, single-arm, investigational study with follow-up at 30 days, 1 year, and annually up to 5 years...

BACKGROUND: Initial data about the performance of the new-generation SAPIEN 3 Ultra (S3U) valve are highly promising. However, evidence about the longer-term performance and safety of the S3U is scarce. AIMS: We aimed to investigate the 1-year clinical and echocardiographic outcomes of transcatheter aortic valve implantation (TAVI) using the S3U compared with its predecessor, the SAPIEN 3 valve (S3). METHODS: The SAPIEN 3 Ultra registry included consecutive patients who underwent transfemoral TAVI at 12 European centres with the S3U or S3 between October 2016 and December 2020...

BACKGROUND: Evidence of prognostic factors for stent failure after drug-eluting stent implantation for calcified nodules (CNs) is limited. AIMS: We aimed to clarify the prognostic risk factors associated with stent failure among patients who underwent drug-eluting stent implantation for CN lesions using optical coherence tomography (OCT). METHODS: This retrospective, multicentre, observational study included 108 consecutive patients with CNs who underwent OCT-guided percutaneous coronary intervention (PCI)...

Provisional stenting has become the default technique for the treatment of most coronary bifurcation lesions. However, the side branch (SB) can become compromised after main vessel (MV) stenting and restoring SB patency can be difficult in challenging anatomies. Angiographic and intracoronary imaging criteria can predict the risk of side branch closure and may encourage use of side branch protection strategies. These protective approaches provide strategies to avoid SB closure or overcome compromise following MV stenting, minimising periprocedural injury...

BACKGROUND: Early P2Y12 inhibitor monotherapy has emerged as a promising alternative to 12 months of dual antiplatelet therapy following percutaneous coronary intervention (PCI). AIMS: In this single-arm pilot study, we evaluated the feasibility and safety of ticagrelor or prasugrel monotherapy directly following PCI in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). METHODS: Patients received a loading dose of ticagrelor or prasugrel before undergoing platelet function testing and subsequent PCI using new-generation drug-eluting stents...

Despite significant advances in pharmacological, electrophysiological and valve therapies for heart failure with reduced ejection fraction (HFrEF), the associated morbidity, mortality and healthcare costs remain high. With a constantly growing heart failure population, the existing treatment gap between current and advanced heart failure therapies (e.g., left ventricular [LV] assist devices, heart transplantation) reflects a large unmet need, calling for novel therapeutic approaches. Left ventricular remodelling and dilatation, with or without scar formation, is the hallmark of cardiomyopathy and is associated with poor prognosis...
