A Novel Protocol for Contrast-Free Transcatheter Aortic Valve Replacement Evaluation and Implantation.

Background: We aimed to develop a transcatheter aortic valve replacement (TAVR) sizing algorithm and implantation method to facilitate safe and effective TAVR without contrast use in patients with severe chronic kidney disease (CKD) who do not yet require renal replacement therapy. Patients with CKD are a challenging patient subset to treat using standard TAVR care pathways which most usually require the use of iodinated contrast media both during gated computed tomography (CT) angiography sizing, and valve deployment. Iodinated contrast exposure may worsen kidney function in a dose-dependent fashion, and may result in a need for renal replacement therapy.

Transcatheter Mitral Valve Replacement Using Annular Reduction by Cinching With TEER in the Commissure (ARCTIC).

Background: Mitral annular calcification with valve dysfunction remains a challenging syndrome. Operative risk is high, and available transcatheter therapies are limited.

Methods: This study describes our initial experience with a novel procedure to address large mitral annuli when no surgical or trial-based transcatheter mitral valve replacement device is available.

Radiation Exposure to the Interventional Echocardiographers and Sonographers: A Call to Action.

Interventional echocardiography is a rapidly growing field within the disciplines of cardiology and anesthesiology, with the rise of advanced transcatheter procedures making skilled imagers more important than ever. However, these procedures also involve frequent manipulation of the transesophageal echocardiography probe, which means interventional echocardiographers (IEs) are at risk of long-term occupational radiation exposure. Studies have shown that radiation exposure is linked to various health issues, including cancer, cataracts, hypertension, hyperlipidemia, endothelial dysfunction, vascular aging, and early atherosclerosis.

Practical Considerations for Obtaining Perioperative Transesophageal Echocardiography Accreditation: Collective Experiences at Early-Adopting Centers.

The Intersocietal Accreditation Commission (IAC) is a nonprofit accrediting organization committed to ensuring the quality of diagnostic imaging and related procedures. It comprises a collaboration of stakeholders spanning numerous medical professionals and specialties. In a recent initiative, IAC Echocardiography introduced a new accreditation specifically for Perioperative Transesophageal Echocardiography (PTE).

Recommendations for Special Competency in Echocardiographic Guidance of Structural Heart Disease Interventions: From the American Society of Echocardiography.

Transcatheter therapies for structural heart disease continue to grow at a rapid pace, and echocardiography is the primary imaging modality used to support such procedures. Transesophageal echocardiographic guidance of structural heart disease procedures must be performed by highly skilled echocardiographers who can provide rapid, accurate, and high-quality image acquisition and interpretation in real time. Training standards are needed to ensure that interventional echocardiographers have the necessary expertise to perform this complex task.

Interobserver Variation in Echocardiographic Measurements and Grading of Tricuspid Regurgitation Based on a Novel Web-Based Assessment Environment.

Objectives: The primary aim of this study was to assess interobserver variability in grading tricuspid regurgitation (TR) severity. The authors' secondary goals were to delineate which transesophageal echocardiographic (TEE) parameters best correlate with severity and how consistent the participants were at grading severity.

Design: This was a prospective cohort study of how clinicians evaluated previously acquired TEE images and videos.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database: 2021 Update on Echocardiography.

The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) is the world's premier clinical outcomes registry for adult cardiac surgery and a driving force for quality improvement in cardiac surgery. Echocardiographic data provide a wealth of hemodynamic, structural, and functional data and have been part of STS ACSD data collection since its inception. An increasing body of evidence suggests that the use of echocardiography in patients undergoing cardiac surgery has a positive impact on postoperative outcomes.

Incidence and standardised definitions of mitral valve leaflet adverse events after transcatheter mitral valve repair: the EXPAND study.

Background: An independent panel of experts reviewed all investigator-reported cases of mitral valve leaflet adverse events (LAE) after MitraClip NTR/XTR in the EXPAND study.

Aims: We aimed to report the findings of the expert panel and standardise definitions for LAE.

Methods: Standard definitions for different types of LAE were formulated and events adjudicated after detailed review by the expert panel.

State of the Art: Transcatheter Edge-to-Edge Repair for Complex Mitral Regurgitation.

Transcatheter edge-to-edge mitral valve repair has revolutionized the treatment of primary and secondary mitral regurgitation. The landmark EVEREST (Endovascular Valve Edge-to-Edge Repair Study) and COAPT (Clinical Outcomes Assessment of the MitraClip Percutaneous Therapy for High Surgical Risk Patients) trials included only clinically stable patients with favorable mitral valve anatomy for edge-to-edge repair. However, since its initial commercial approval in the United States, growing operator experience, device iterations, and improvements in intraprocedural imaging have led to an expansion in the use of transcatheter edge-to-edge repair to more complex mitral valve pathologies and clinical scenarios, many of which were previously considered contraindications for the procedure.

Initial experience with the fourth generation MitraClip™: Outcomes, procedural aspects, and considerations for device selection.

Objectives: We present our initial experience with the fourth-generation MitraClip™ (G4) system and propose preliminary criteria for device selection.

Background: The MitraClip™ G4 system recently underwent a "controlled release" for transcatheter edge-to-edge mitral valve repair. The four new devices include technical improvements such as controlled gripper actuation (independent leaflet capture) and continuous left atrial pressure monitoring.

Echocardiographic Guidance of Intentional Leaflet Laceration prior to Transcatheter Aortic Valve Replacement: A Structured Approach to the Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Artery Obstruction Procedure.

Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) is a recently developed technique to reduce the risk of ostial coronary obstruction during transcatheter aortic valve replacement. Intraprocedural fluoroscopy and transesophageal echocardiography imaging are used complimentarily to guide the procedure. So far, no structured echocardiographic imaging protocol has been described for this intervention.

Contemporary Transcatheter Mitral Valve Replacement for Mitral Annular Calcification or Ring.

Objectives: The aim of this study was to evaluate outcomes of commercial transcatheter mitral valve replacement (TMVR) for annular rings and calcification using contemporary techniques.

Background: TMVR is evolving in the absence of other viable treatment options for severe mitral annular calcification and failing ring repairs. The concomitant use of laceration of the anterior mitral valve leaflet to prevent left ventricular outflow tract obstruction and pre-emptive alcohol septal ablation is not well studied in clinical practice.

The Adult Cardiac Anesthesiology Section of STS Adult Cardiac Surgery Database: 2020 Update on Quality and Outcomes.

The Society of Cardiovascular Anesthesiologists, in partnership with The Society of Thoracic Surgeons, has developed the Adult Cardiac Anesthesiology Section of the Adult Cardiac Surgery Database. The goal of this landmark collaboration is to advance clinical care, quality, and knowledge, and to demonstrate the value of cardiac anesthesiology in the perioperative care of cardiac surgical patients. Participation in the Adult Cardiac Anesthesiology Section has been optional since its inception in 2014 but has progressively increased.
