Comparison of Alcohol Septal Ablation With Mavacamten in Obstructive Hypertrophic Cardiomyopathy.

Obstructive hypertrophic cardiomyopathy (HCM) is associated with significant morbidity attributed to left ventricular outflow tract (LVOT) obstruction. Although alcohol septal ablation (ASA) is an established interventional treatment, mavacamten, a novel cardiac myosin inhibitor, has emerged as a noninvasive pharmacologic alternative. Understanding the comparative efficacy of these 2 treatments is important for optimizing patient care.

Managing Left Ventricular Outflow Tract Obstruction in Combined Aortic Stenosis and Hypertrophic Cardiomyopathy.

This study presents an elderly man with sequential hemodynamic obstructions caused by hypertrophic cardiomyopathy and aortic stenosis. Septal reduction therapy was performed to avoid outflow tract obstruction associated with potential future transcatheter aortic valve replacement. This case highlights the importance of resolving outflow tract obstruction during assessment of aortic valve disease.

Perceived usability and acceptability of the My-Hip Fracture risk communication tool from the perspective of academic clinicians.

Objective: We evaluated the usability and acceptability of My-Hip Fracture (My-HF), a web application that assists providers in delivering individualized prognostic information to patients hospitalized for hip fracture (HF).

Methods: We observed a sample of 16 clinicians as they navigated My-HF. We then administered a structured questionnaire and conducted semi-structured interviews to explore participants' opinions about the app's content and the feasibility of incorporating the app into clinical workflows.

Cardiac Structural and Functional Remodeling After Transcatheter Mitral Valve in Valve Implantation: Early Changes and Prognostic Significance.

Background: Transcatheter mitral valve-in-valve (MViV) replacement has emerged as an alternative to redo mitral valve (MV) surgery for the management of failed bioprosthetic MVs. The degree of cardiac remodeling assessed by echocardiography has been shown to have prognostic implications in degenerative mitral regurgitation patients undergoing MV surgery. The impact of transcatheter MViV in patients with degenerative bioprosthetic MV failure on cardiac remodeling and its associated prognosis remains undescribed.

Age-Stratified Surgical Aortic Valve Replacement for Aortic Stenosis.

Background: The management of aortic stenosis has evolved to stratification by age as reflected in recent societal guidelines. We evaluated age-stratified surgical aortic valve replacement (SAVR) trends and outcomes in patients with bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) from The Society of Thoracic Surgeons Adult Cardiac Surgery Database.

Methods: This cohort included adults (≥18 years) undergoing SAVR for severe aortic stenosis between July 2011 and December 2022.

Echocardiographic parameters associated with less reverse left ventricular remodeling after transcatheter aortic valve implant in subjects with prosthesis patient mismatch.

Background: Transaortic valve implant (TAVI) is the treatment of choice for severe aortic stenosis (AS). Some patients develop prosthesis patient mismatch (PPM) after TAVI. It is challenging to determine which patients are at risk for clinical deterioration.

Percutaneous coronary intervention for ventricular fibrillation in the setting of an anomalous right coronary artery.

We present a case of a quadriplegic male who developed ventricular fibrillation associated with an anomalous aortic origin of the right coronary artery. Successful revascularization was achieved with percutaneous coronary intervention. This case highlights the application of an unconventional approach to resolve ischemia in a patient with prohibitive surgical risk.

Comparison of Hospital Online Price and Telephone Price for Shoppable Services.

Importance: US hospitals are required to publicly post their prices for specified shoppable services online. However, the extent to which a hospital's prices posted online correlate with the prices they give to a telephone caller is unknown.

Objective: To compare hospitals' online cash prices for vaginal childbirth and brain magnetic resonance imaging (MRI) with prices offered to secret shopper callers requesting price estimates by telephone.

Conformational changes during in vitro balloon fracture of internal aortic annuloplasty ring.

Objective: HAART 300 300 (BioStable Science and Engineering, Inc) aortic annuloplasty rings restore physiologic annular geometry during aortic valve repair. Transcatheter valve-in-ring implantation is appealing for recurrent valve dysfunction but may necessitate balloon fracture of downsized annuloplasty rings. We characterized the feasibility of ring fracture and changes in ring geometry preceding fracture.

Case report: Multimodality imaging of unusual coronary to pulmonary collaterals in chronic thromboembolic pulmonary hypertension.

We present unusual coronary-pulmonary collaterals in a 65-year-old CTEPH patient. Perfusion mapping of a dual-energy computed tomography (DECT) study revealed areas of right lung that were minimally perfused despite unilateral occlusion of the right pulmonary artery, leading to the discovery of coronary-pulmonary collaterals invasive coronary angiography. Pulmonary thromboendarterectomy removed the clot en-bloc.

Race-Specific Impact of Conventional Surgical Risk Score on 1-Year Mortality After Transcatheter Aortic Valve Replacement.

Background: Interracial differences in the distribution and prognostic value of conventional Society of Thoracic Surgeons (STS) score on long-term mortality after transcatheter aortic valve replacement (TAVR) are uncertain.

Objectives: This study aims to compare the impact of STS scores on clinical outcomes at 1-year after TAVR between Asian and non-Asian populations.

Methods: We used the Trans-Pacific TAVR (TP-TAVR) registry, a multinational multicenter, observational registry involving patients undergoing TAVR at 2 major centers in the United States and 1 major center in Korea.

Use of Mechanical Circulatory Support in Chronic Total Occlusion Percutaneous Coronary Intervention.

The use of mechanical circulatory support (MCS) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We analyzed the clinical and angiographic characteristics, and procedural outcomes of 7,171 CTO PCIs performed between 2012 and 2021 at 35 international centers. Mean age was 64.

Percutaneous coronary intervention of chronic total occlusions involving a bifurcation: Insights from the PROGRESS-CTO registry.

Background: The impact of bifurcations at the proximal or distal cap on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study.

Methods: We analyzed the clinical, angiographic, and procedural data of 4,584 cases performed in patients between 2012 and 2020 in a global CTO PCI registry. We compared 4 groups according to the bifurcation location: "proximal cap," "distal cap," "proximal and distal cap," and "no bifurcation.
