Background: Bare stents has become the first line therapy for aortic coarctation. Covered stents has been reported more recently in clinical practice.
Objectives: Our goal was to summarize the outcome for all subjects evaluated during a prospective clinical study in the United States with the GORE® HELEX® Septal Occluder for transcatheter repair of secundum atrial septal defects (ASD).
Objectives: Whether predicting the risk of early serum creatinine rise using the ratio of the volume of contrast media administered to the estimated creatinine clearance (V/CrCl) is applicable to the broader definition of contrast-induced nephropathy (CIN) (≥0.5 mg/dL absolute and/or 25% relative increase from baseline serum creatinine) is unknown.
Objectives: To assess the clinical effects of postdilatation of drug-eluting stents (DES).
Objectives: To compare biodegradable polymer biolimus-eluting (BES) with abluminal drug elution and durable polymer everolimus-eluting (EES) stents in the treatment of bifurcation lesions.
Objective: Drug-eluting stent (DES) implantation is a very effective treatment of bare-metal stent–in-stent restenosis (BMS–ISR). Therapeutic options for drug-eluting stent–in-stent restenosis (DES–ISR) are less well defined, as there are only few data on safety and effectiveness of interventional modalities. This study compared the 1-year clinical outcome after the use of drug-eluting balloon (DEB) to second-generation everolimus-eluting stent (EES) for treatment of DES–ISR.
Objectives and Background: The impact of underexpansion and minimal stent area (MSA) criteria in the second generation drug-eluting stents (DES) has not been addressed yet.
Objectives: We describe the first report of a transcatheter Sapien implantation in a native tricuspid valve after multiple failed surgical repairs with a lack of prosthetic material and radiographic landmarks.
Objectives: To determine the procedural safety, safety, and efficacy of left atrial appendage (LAA) occlusion in octogenarians.
Objective: To evaluate the safety of percutaneous left atrial appendage (LAA) closure with the Amplatzer Cardiac Plug (ACP) in patients with nonvalvular atrial fibrillation (AF) who are not eligible for oral anticoagulation with warfarin.
Objectives: Balloon valvuloplasty (BV) before transcatheter aortic implantation has been thought to be mandatory before the valve is implanted. We have explored the feasibility and safety of direct implantation of balloon expandable Edwards SAPIEN XT valve without prior balloon dilatation.
Objectives: In this study, we examined the predictive value of the left ventricular end-diastolic pressure (LVEDP) in patients undergoing balloon aortic valvuloplasty (BAV)
Objectives: Transcatheter patent ductus arteriosus (PDA) occlusion is a staple of pediatric catheterization laboratories. We present the phenomenon of significant PDA spasm to prevent failure to occlude a hemodynamically significant duct.
Objective: To evaluate the impact of a device-mediated modification of the injection pressure profile on iodinated contrast volumes during coronary angiography and percutaneous coronary intervention (PCI).
Background: Great strides have been made in improving outcomes for patients with ST-elevation myocardial infarction (STEMI), predominately through initiatives focusing upon improving clinical processes “upstream” of percutaneous coronary intervention (PCI). The actual step-by-step mechanics of diagnostic angiography during STEMI and other aspects of the PCI procedure itself have received relatively little attention.
