Introduction And Objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria.
Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR.
Background: Data comparing valve systems in the valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) field have been obtained from retrospective studies.
Objectives: The authors sought to compare the 1-year hemodynamic performance and clinical outcomes between balloon-expandable valves (BEV) SAPIEN 3/ULTRA (Edwards Lifesciences) and self-expanding valves (SEV) Evolut R/PRO/PRO+ (Medtronic) in ViV-TAVR.
Methods: Patients with a failed small (≤23 mm) surgical valve undergoing ViV-TAVR were randomized to receive a SEV or a BEV.
Background: The SavvyWire (OpSens Inc) is a 0.035-inch preshaped guidewire with dedicated pacing properties and a distal pressure sensor allowing for continuous hemodynamic pressure monitoring.
Objectives: This study sought to determine the efficacy and safety of the guidewire during transcatheter aortic valve replacement (TAVR) procedures.
Background: The optimal treatment in patients with severe aortic stenosis and small aortic annulus (SAA) remains to be determined. This study aimed to compare the hemodynamic and clinical outcomes between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in patients with a SAA.
Methods: This prospective multicenter international randomized trial was performed in 15 university hospitals.
Background: Data comparing valve systems in the valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) field have been obtained from retrospective studies.
Objectives: The purpose of this study was to compare the hemodynamic results between the balloon-expandable valve (BEV) SAPIEN (3/ULTRA, Edwards Lifesciences) and self-expanding valve (SEV) Evolut (R/PRO/PRO+, Medtronic) in ViV-TAVR.
Methods: Patients with a failed small (≤23 mm) surgical valve were randomized to receive a BEV or an SEV.
Background: The arrhythmic burden after discharge in patients with new-onset left bundle branch block (LBBB) undergoing transcatheter aortic valve replacement (TAVR) with the balloon-expandable SAPIEN 3 (S3) valve remains largely unknown.
Objective: The purpose of this study was to determine the incidence of late arrhythmias in patients with new-onset LBBB undergoing TAVR with the balloon-expandable S3 valve.
Methods: This was a multicenter, prospective study that included 104 consecutive TAVR patients with new-onset persistent LBBB following TAVR with the S3 valve.
Aims: We determined the incidence and type of arrhythmias at 2-year follow-up in patients with new-onset persistent left bundle branch block (LBBB) following transcatheter aortic valve replacement (TAVR).
Methods And Results: Multicentre prospective study including 103 consecutive patients with new-onset persistent LBBB post-TAVR (SAPIEN XT/3: 53; CoreValve/Evolut R: 50). An implantable cardiac monitor (Reveal XT, Reveal Linq) was implanted before hospital discharge and patients had continuous monitoring for up to 2 years.
Background: Transcarotid transcatheter aortic valve replacement (TAVR) recipients may be exposed to a higher ipsilateral subclinical cerebral ischemic burden compared with the contralateral hemisphere. We sought (1) to compare the cerebral ischemic burden of the 2 hemispheres after transcarotid TAVR, as evaluated by diffusion weighted-magnetic resonance imaging (DW-MRI), and (2) to identify the factors associated with ipsilateral ischemic burden.
Methods: This prospective study included 52 patients undergoing transcarotid TAVR, followed by a DW-MRI examination.
Background: Scarce data exist on transcatheter heart valve (THV) performance evaluated by cardiac magnetic resonance (CMR) in newer generation THV patients. Furthermore, it has been suggested that echocardiographic evaluation after TAVR may inaccurately assess residual AR in some patients. This study aimed to determine the incidence and severity of aortic regurgitation (AR) assessed by CMR in patients undergoing TAVR with the SAPIEN 3 valve, and evaluate the agreement between CMR and transthoracic echocardiography (TTE) on the assessment of AR severity in such patients.

Background: Scarce data exist on the arrhythmic burden of TAVR candidates (pre-procedure).
Methods: This was a prospective study including 106 patients with severe aortic stenosis and no prior permanent pacemaker screened for TAVR.
Objectives: This study sought to determine the incidence, clinical impact, and changes over time of mitral regurgitation (MR) in patients with low-flow, low-gradient aortic stenosis (LFLG-AS) undergoing transcatheter aortic valve replacement (TAVR).
Background: Few data exist on the clinical impact and changes in severity over time of MR in patients with LFLG-AS undergoing TAVR.
Methods: A total of 308 TAVR candidates with LFLG-AS were included.
This study sought to determine, in patients with new-onset persistent left bundle branch block (NOP-LBBB) after transcatheter aortic valve implantation (TAVI), the incidence and factors associated with (i) LBBB recovery and (ii) permanent pacemaker implantation (PPI) at 1-year follow-up. This was a multicenter study including 153 patients (mean age: 81 ± 5 years, 56% of women) with NOP-LBBB post-TAVI (balloon-expandable valve in 112 patients). Delta PR (ΔPR) and delta QRS (ΔQRS) were defined as the difference in PR and QRS length between baseline and hospital discharge ECG, and the relative ΔPR and ΔQRS as absolute ΔPR and ΔQRS divided by baseline PR and QRS length, respectively.

Background: Paclitaxel-coated balloon (PCB) coronary angioplasty is an alternative treatment for de-novo coronary lesions in small vessels. This study with the new Essential PCB aimed to evaluate early and mid-term clinical outcomes following angioplasty with the Essential PCB in the treatment of de-novo lesions in small vessels.
Patients And Methods: We included all patients who underwent PCB angioplasty for treating de-novo coronary lesions in small vessels (reference diameter <2.
Background: Few data exist on patients with low-flow, low-gradient aortic stenosis (LFLG-AS) undergoing transcatheter aortic valve replacement (TAVR). Also, very scarce data exist on the usefulness of dobutamine stress echocardiography (DSE) before TAVR in these patients.
Objectives: The authors sought to evaluate clinical outcomes and changes in left ventricular ejection fraction (LVEF) following TAVR in patients with classical LFLG-AS.
Background: Pre-clinical results of a novel open-cell, thin strut, durable polymer, laser cut cobalt chromium sirolimus-eluting stent (Angiolite) were promising. Using quantitative optical coherence tomographic (OCT) analyses, we explored the healing characteristics of the Angiolite DES system at 3- and 6-months post implantation.
Methods: A total of 103 patients with de novo coronary lesions underwent percutaneous coronary intervention with the Angiolite DES and were randomized 1:3 into two cohorts for angiographic and OCT follow-up, with 28 and 70 patients returning for 3- or 6-month post-PCI surveillance, respectively.
Background: While transcatheter aortic valve implantation (TAVI) is established for treating high-operative risk surgical aortic valve replacement candidates, until recently the smallest transcatheter heart valve (THV) measured 23 mm, posing greater risk for annular rupture and THV failure in patients with aortic stenosis (AS) with small aortic annuli (≤20 mm).
Objectives: In the setting of a multicentre registry, we report on the safety, efficacy and early clinical outcomes of the SAPIEN XT 20 mm balloon-expanding THV.
Results: Among TAVI 55 recipients (n=30 for native AS, n=25 for a valve-in-valve procedure (V-in-V)), median age and Society of Thoracic Surgeons score were 85 (81 to 87) years and 7.
Objectives: Studies performed in rodents have suggested a role for proprotein convertase subtilisin/kexin type 9 (PCSK9) in insulin resistance and impaired body fat distribution. Our objective was to examine the relationships between markers of adiposity and insulin resistance and plasma PCSK9 levels in humans. In addition, we explored the effect of a one-year lifestyle modification program on plasma PCSK9 levels in abdominally obese, dyslipidemic men.
