Article Abstract
Aortic valve stenosis (AS) severity can be estimated by various modalities. Due to some of the limitations of the currently available methods, the usefulness of live three-dimensional transthoracic echocardiography (3D TTE) in the assessment of AS was explored. Live 3D TTE was able to visualize the aortic valve orifice in all 11 patients studied. Live 3D TTE correctly estimated the severity of AS in all 10 patients in whom AS severity could be evaluated at surgery. These included eight patients with severe AS and two with moderate AS. Two of these 10 patients with AS had associated hypertrophic cardiomyopathy and underwent myectomy at the time of aortic valve replacement. Aortic valve orifice area measurements by live 3D TTE correlated well with intraoperative three-dimensional transesophageal echocardiographic reconstruction measurements (r=0.85) but not as well with two-dimensional transesophageal echocardiography measurements (r=0.64). Live 3D TTE measurements of the aortic valve orifice area also did not correlate well with two-dimensional transthoracic echocardiography measurements (r=0.46) but the number of patients studied with two-dimensional transthoracic echocardiography was smaller (only seven) and four of these did not undergo two-dimensional transthoracic echocardiography at the authors' institution. Altogether, four patients with severe AS by live 3D TTE, and subsequently confirmed at surgery, were misdiagnosed as having moderate AS by two-dimensional transthoracic echocardiography. Because it is completely noninvasive and views the aortic valve in three dimensions, 3D TTE could be a useful complement to the existing modalities in the evaluation of AS severity.

Comparative Effectiveness of TAVI Platforms and Surgical Aortic Valve Replacement: A Network Meta-Analysis of Randomized Controlled Trials.
Circ Cardiovasc Interv

Keele Cardiovascular Research Group, Keele University, United Kingdom (M.A.M., R.B.).
Background: Evidence informing clinical guidelines assumes that all transcatheter aortic valve implantation (TAVI) devices have similar effectiveness, in other words, displaying a class effect across TAVI valves. We aimed to assess the comparative effectiveness of different TAVI platforms relative to other TAVI counterparts or surgical aortic valve replacement (SAVR).
Methods: MEDLINE/Embase/CENTRAL were searched from inception until April 2025, for randomized controlled trials comparing outcomes with different commercially available TAVI devices relative to other TAVI counterparts or SAVR.

Background: Congenital aortic valvar disease represents a heterogeneous population with suboptimal surgical repair or replacement outcomes. We assess our approach and short-term outcomes in this population using cardiac CT evaluation for personalised surgical planning and execution.
Methods: We assessed patients who underwent aortic valvar surgery from February 2022 to August 2024.
Outcomes of Fluoroscopy-Based Asymmetric Underexpansion With the Self-Expanding ACURATE Neo and Neo2 Valve.
Catheter Cardiovasc Interv

Department of Cardiology, Heart and Lung Center, Helsinki University Hospital and University of Helsinki, Helsinki, Finland.
Background: Asymmetric underexpansion of transcatheter heart valves (THVs), as observed on fluoroscopy, may influence prosthesis function or long-term durability of transcatheter aortic valve implantation (TAVI).
Aims: This study aimed to evaluate the effect of stent frame asymmetry on hemodynamic performance and clinical outcomes in ACURATE neo and neo2 THVs.
Methods: In a retrospective registry, the TAVI asymmetry index was defined as the ratio of the THV stent frame diameter.

Background: Routine preoperative echocardiograms (ECHOs) are frequently obtained in patients undergoing minimally invasive repair of pectus excavatum (MIRPE), but the benefit and necessity of preoperative screening remain debated. In this study, we sought to quantify the proportion of preoperative ECHOs that had clinically significant findings.
Methods: We conducted a retrospective review of 255 patients who underwent MIRPE at a single pediatric referral center from 2018 to 2023.
Oral anticoagulation in patients with atrial fibrillation and heart valve prosthesis: a substudy from the LAAOS III Trial.
J Thorac Cardiovasc Surg

Population Health Research Institute, Hamilton Health Sciences, McMaster University, Ontario, Canada.
Objective: Societal guidelines recommend vitamin K antagonists (VKAs) for atrial fibrillation patients with recent biological valve implantation, but the safety and efficacy of direct oral anticoagulants (DOACs) in this setting remain uncertain, especially in the early postoperative period. This substudy of the Left Atrial Appendage Occlusion Study (LAAOS) III trial aimed to compare thromboembolic and bleeding outcomes in patients discharged on VKAs versus DOACs after bioprosthesis implantation or mitral valve repair.
Methods: A total of 2,645 patients were included, with 461 discharged on DOACs and 2184 on VKAs.
