Background. OBSERVANT represents the first national observational study on the comparative effectiveness of transcatheter aortic valve implantation (TAVI) vs surgical aortic valve replacement (SAVR) at short, medium and long term, in a patient population with severe aortic stenosis (AS). The aim of this paper is to describe patient...

Background There is a paucity of prospective and controlled data on the comparative effectiveness of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in a real-world setting. Objectives This analysis aims to describe 1-year clinical outcomes of a large series of propensity-matched patients who...

Risk stratification tools used in patients with severe aortic stenosis have been mostly derived from surgical series. Although specific predictors of early mortality with transcatheter aortic valve replacement (TAVR) have been identified, the prognostic impact of their combination is unexplored. We sought to develop a simple score, using...

Objective Despite demonstration of the superior outcomes of transcatheter aortic valve implantation (TAVI) versus optimal medical therapy for severe left ventricular systolic dysfunction, studies comparing TAVI and surgical aortic valve replacement (AVR) in this high-risk group have been lacking. Methods We performed propensity matching for...

Background - The proven efficacy of transcatheter aortic valve implantation (TAVI) in high-risk patients is leading to the expansion of its indications toward lower-risk patients. However, this shift is not supported by meaningful evidence of its benefit over surgical aortic valve replacement (SAVR). This analysis aims to describe outcomes of...

Objective To evaluate outcomes of monitored anesthesia care (MAC) compared with general anesthesia (GA) in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR). Design Secondary analysis from the observational and prospective OBSERVANT (OBservational Study of Effectiveness of avR–taVi procedures for severe Aortic...

A few studies recently reported controversial results with transfemoral transcatheter aortic valve replacement (TF-TAVR) versus transapical transcatheter aortic valve replacement (TA-TAVR), often without adequate adjusted analysis for baseline differences. Data on patients who underwent TF-TAVR and TA-TAVR from the Observational Study of...

Background There are scarce data on outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in patients with renal failure. Methods We evaluated the impact of renal failure on outcomes after TAVI and SAVR and compared the results of these procedures in patients with chronic kidney disease...

The aim of this study was to analyze procedural and postprocedural outcomes of patients aged ≥80 years treated by transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) as enrolled in the OBservational Study of Effectiveness of SAVR-TAVR procedures for severe Aortic steNosis Treatment (OBSERVANT) Study. TAVI...

Background-—Multiple percutaneous coronary interventions (PCIs) are considered determinant of poor outcome in patients undergoing coronary artery bypass grafting (CABG), but scarce data exist to substantiate this. Methods and Results-—Patients who underwent CABG without history of prior PCI or with PCI performed >30 days before surgery were...

Background - The clinical impact of prior percutaneous coronary intervention (PCI) in patients requiring coronary artery bypass grafting (CABG) remains unsettled. We sought to determine whether prior PCI is associated with adverse outcome after CABG. Methods and Results - Data from the prospective E-CABG (European Multicenter Study on Coronary...

Severe perioperative bleeding after coronary artery bypass grafting (CABG) is associated with poor outcome. An additive score for prediction of severe bleeding was derived (n=2494) and validated (n=1250) in patients from the E-CABG registry. Severe bleeding was defined as E-CABG bleeding grades 2-3 (transfusion of >4 units of red blood cells or...

To develop a risk score for deep sternal wound infection (DSWI) after isolated coronary artery bypass grafting (CABG).

Aims No data exists on inter-institutional differences in terms of adherence to international guidelines regarding the discontinuation of antithrombotics and rates of severe bleeding in coronary artery bypass grafting (CABG). Methods and results This is an analysis of 7118 patients from the prospective multicentre European CABG (E-CABG)...

Objectives: The aim of this study was to evaluate the prognostic impact of untreated asymptomatic carotid artery stenosis (CS) in patients undergoing isolated coronary artery bypass grafting (CABG). Methods: This was a post hoc analysis of data from a prospective multicentre observational study. Patients without history of stroke or transient...

Perioperative bleeding is a determinant of poor outcome in patients undergoing coronary artery bypass grafting (CABG), but there is a lack of adequate stratification of its severity. The ability of the European registry of Coronary Artery Bypass Grafting (E-CABG), Universal Definition of Perioperative Bleeding (UDPB), Study of Platelet...
