Background: Left ventricular obstruction (LVO) is an infrequent complication following transcatheter aortic valve replacement (TAVR) that can lead to severe hemodynamic decompensation. Previous studies have analyzed the pathophysiology of this clinical entity; however, little is known about the anatomical characteristics as assessed by computational tomography (CT) of patients at risk.
Methods: Data from 349 patients were retrospectively analyzed from a single center registry of patients undergoing TAVR at San Raffaele Hospital, Milan, Italy, between January 2020 and December 2021.
Background: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve (BAV) disease is still burdened by a non-negligible rate of stroke and permanent pacemaker implantation (PPI). These suboptimal results, possibly related to the unique BAV anatomy, might suggest the use of a different sizing method in this setting. The aim of our study is to evaluate whether the application of the supra-annular LIRA method might improve clinical outcomes in this population.

In order to reduce waiting lists, provide to all patients referred to us equal access to care and to further improve the collaboration with spoke centers, we developed a specific Hub & Spoke specific protocol for TAVI. According to our protocol, a clinical selection (with echo and computed tomography scan) is done by Spoke centers, the case is discussed with a multidisciplinary team online and the procedure is planned (access, valve type size).

In some adults, PFO may result in a potential for shunting venous thromboembolism to the arterial circulation; less frequently it can cause interatrial, right-to-left shunting of deoxygenated blood. The pathogenesis of several medical conditions is related to the presence of PFO.

Aims: We sought to assess whether MRR is associated with adverse cardiac remodelling, a low-flow phenotype and extravalvular cardiac damage (EVCD) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI).
Methods: Invasive thermodilution-based assessment of the coronary microvascular function of the left anterior descending artery was performed in a prospective, multicentre cohort of patients undergoing TAVI.
Unlabelled: Hemoglobin (Hb) levels have emerged as a useful tool for risk stratification and the prediction of outcome after myocardial infarction. We aimed at evaluating the prognostic impact of this parameter among patients in advanced age, where the larger prevalence of anemia and the higher rate of comorbidities could directly impact on the cardiovascular risk.
Methods: All the patients in the ELDERLY-2 trial, were included in this analysis and stratified according to the values of hemoglobin at admission.
Aims: The aim of this study was to minimize the procedure, and reduce the length of hospital stay (LoS) is the future objective for transcatheter aortic valve replacement (TAVI).Aims of the study are to identify procedural and electrocardiographical predictors of fast-track discharge in patients who underwent TAVI.
Methods: Patients treated with TAVI included in the One Hospital ClinicalService project were categorized according to the LoS.
Background: prior statin treatment has been shown to have favourable effects on short- and long-term prognosis in patients with acute coronary syndrome (ACS). There are limited data in older patients. The aim of this study was to investigate the association of previous statin therapy and presentation characteristics, infarct size and clinical outcome in older patients, with or without atherosclerotic cardiovascular disease (ASCVD), included in the Elderly-ACS 2 trial.

Therefore, transcatheter bioprostheses durability appears of critical importance. Aim of the present study is to evaluate mid-term outcomes of TAVI in a high-volume single center cohort.
View Article and Find Full Text PDFIntroduction: Based on recent data, the indication for transcatheter aortic valve implantation (TAVI) is expanding to individuals at lower surgical risk, who are generally younger than subjects historically treated for severe aortic stenosis. Indeed, younger patients have traditionally been under-represented in current TAVI literature. The aim of the present study is to report about clinical features, procedural outcomes and mid-term outcomes of patients younger than 70 who underwent TAVI in a single high-volume center.

Whether this difference persists in elderly patients undergoing similar invasive treatment has not been studied. We investigated sex-related differences in 1-year outcome of elderly acute coronary syndrome patients treated by percutaneous coronary intervention (PCI).

Objectives: This report aims to provide a comprehensive overview of this complication focusing on predisposing factors, clinical presentation, diagnostic findings, treatment and clinical outcomes.
Background: The residual burden of coronary artery disease after percutaneous coronary intervention (PCI) has been associated with worse ischemic outcome. However, data are conflicting in elderly patients. The aim of our study was to verify the incremental value of the residual ergy Between Percutaneous Coronary Intervention With us and Cardiac Surgery (SYNTAX) score (rSS) over clinical variables and baseline SYNTAX score (bSS) in predicting 1-year mortality or cardiovascular events.

We aimed to assess the prevalence and independent prognostic impact of valvular heart disease (VHD) diagnosed during the index hospitalization on clinical outcomes among elderly patients with ACS. Included VHDs were moderate-to-severe mitral regurgitation (MR), moderate-to-severe aortic stenosis (AS), or both combined.

Therefore, the aim of this study was to compare the prognosis of patients aged ≥75 years admitted for an ACS with or without previous history of CABG. The primary outcome of the study was a composite of overall mortality, recurrent nonfatal myocardial infarction, nonfatal stroke, and rehospitalization for heart failure at 1-year follow-up.

Background: Limited data on BMS usage in current clinical practice are available.
Methods: All patients who underwent PCI with at least one BMS implantation in 18 Italian centers from January 1, 2013 to December 31, 2017, were included in our registry.
