A Novel Flow-Based Parameter of Collateral Function Assessed by Intracoronary Thermodilution

Currently, many methods for quantitation of coronary collateral function are based on intracoronary pressure measurements distal of an occluded balloon, which do not fully account for the dynamic nature of collateral flow. Therefore, a flow-based parameter of coronary collateral function based upon principles of thermodilution was evaluated.



Long-Term Safety and Efficacy of the Everolimus-Eluting Stent Compared to First-Generation Drug-Eluting Stents in Contemporary Clinical Practice

A comparison of the long-term safety and clinical effectiveness of the Xience V everolimus-eluting stent to both the Taxus paclitaxel-eluting stent and the Cypher sirolimus-eluting stent in an unselected patient population.



Longitudinal Deformation of Drug-Eluting Stents: Evaluation by Multislice Computed Tomography

Longitudinal deformation of DES is common in all the studied platforms subject to longitudinal forces. Guiding catheter impingement is the only mechanical action significantly associated with DES shortening.



“Seesaw Balloon-Wire Cutting” Technique as a Novel Approach to “Balloon Uncrossable” Chronic Total Occlusions

Balloon crossing failure after passing a guidewire usually leads to unsuccessful percutaneous recanalization of chronic total occlusions. We offer a novel technique to solve this problem.



Percutaneous Revascularization of a Chronic Total Occlusion of the Left Lower Pulmonary Vein

Percutaneous intervention with angioplasty and stenting is frequently performed for pulmonary vein stenosis, but management of pulmonary vein occlusion remains challenging. We report the case of a 47-year-old female who presented with dyspnea and history of two previous radiofrequency ablation procedures for paroxysmal atrial fibrillation.



Frequency and Evolution of Thin-Capped Fibroatheromas in Left Main Coronary Artery as Assessed by Serial Virtual Histology Intravascular Ultrasound Analysis

A virtual histology intravascular ultrasound assessment of thin-capped fibroatheromas of left main coronary artery and their changes after statin therapy.



Percutaneous Vascular Plug for Incomplete Surgical Left Atrial Appendage Closure

Surgical left atrial appendage (LAA) exclusion has a failure rate as high as 60% due to persistent residual flow in the LAA or large LAA remnants. We describe a novel technique for treatment of incomplete surgical LAA ligation, and define the mechanism that led to persistence of the remnant LAA without any thrombus formation.



Incidence, Predictors, and Effects of Acute Kidney Injury After Percutaneous Valve Implantation

We sought to elucidate incidence, predictors, and effects of acute kidney injury after percutaneous aortic valve implantation.
