Double-Kissing Culotte Technique for Coronary Bifurcation Stenting - Technical evaluation and comparison with conventional double stenting techniques

Original Research | By GG Toth, V Sasi; D Franco et al.

AIMS - To assess, whether Culotte technique could be improved by an additional kissing dilation prior main branch (MB) stenting. METHODS AND RESULTS - Double-kissing (DK) Culotte was compared to Culotte and DK-Crush techniques in bench model (n=24). Results were evaluated for stent apposition, for luminal opening and for flow dynamics.Total procedure duration of DK-Culotte was 18.3±3.4min, si...

Pulmonary Hypertension Caused by a Coconut Left Atrium

Clinical Case Study | By EC Leung, N Hirani et al.

“Coconut atrium” was first described in 1898 and is most commonly associated with rheumatic heart disease. This case demonstrates a dramatic chest x-ray image of extensive circumferential calcification of the left atrium. The abnormality was thought to result in elevated pulmonary pressures and severe right heart failure in the absence of significant mitral valve dysfunction.

Glucose-lowering Drugs or Strategies, Atherosclerotic Cardiovascular Events, and Heart Failure in People With or at Risk of Type 2 Diabetes: An Updated Systematic Review and Meta-Analysis of Randomised Cardiovascular Outcome Trials

Review Article | By OR Ghosh-Swaby, SG Goodman, LA Leite et al.

BACKGROUND - In our 2015 systematic review and meta-analysis of cardiovascular outcome trials for glucose-lowering drugs or strategies in people with or at risk of type 2 diabetes, we reported a modest reduction in atherosclerotic cardiovascular events and an increased risk of heart failure, but with heterogeneous effects by drug or intervention type. In view of the completion of many large cardiovascular outcome trials since our previous analysi...

Double-Kiss-Crush Bifurcation Stenting: Step-by-Step Troubleshooting

Original Research | By AB Hall, I Chavez, S Garcia et al.

The Double-Kiss-crush (DK crush) is the most studied two-stent coronary bifurcation stenting strategy. While published data support its use, DK crush can be challenging to perform. In this review we provide a detailed step-by-step description and troubleshooting for each stage of the DK crush technique.

Transcatheter Aortic Valve Replacement in Low-Risk Patients With Symptomatic Severe Bicuspid Aortic Valve Stenosis

Original Research | By R Waksman, PE Craig, R Torguson et al.

OBJECTIVES - The aim of this study was to evaluate clinical outcomes and transcatheter heart valve hemodynamic parameters after transcatheter aortic valve replacement (TAVR) in low-risk patients with bicuspid aortic stenosis (AS). BACKGROUND - TAVR is approved for low-risk patients in the United States. However, patients with bicuspid AS were excluded from the randomized cohorts o...

The Utility of Rapid Atrial Pacing Immediately Post-TAVR to Predict the Need for Pacemaker Implantation

Original Research | By A Krishnaswamy, Y Sammour, A Mangieri et al.

OBJECTIVES - The aim of this study was to determine the utility of rapid atrial pacing immediately after transcatheter aortic valve replacement (TAVR) to predict the need for permanent pacemaker implantation (PPI). BACKGROUND - Risk stratification for patients without high-grade atrioventricular block (AVB) after TAVR is imprecise and based on anatomic considerations, electrocardiogra...

5-Year Outcomes After TAVR With Balloon-Expandable Versus Self-Expanding Valves: Results From the CHOICE Randomized Clinical Trial

Clinical Trial | By Mohamed Abdel-Wahab, M Landt, Franz-Josef Neumann

OBJECTIVES -The purpose of this study was to evaluate clinical and echocardiographic outcome data of the CHOICE (Randomized Comparison of Transcatheter Heart Valves in High Risk Patients with Severe Aortic Stenosis: Medtronic CoreValve Versus Edwards SAPIEN XT) trial at 5 years. BACKGROUND - The CHOICE trial was designed to compare device performance of a balloon-expandable (BE) tran...
