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 par…
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 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.
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 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 his…
A virtual histology intravascular ultrasound assessment of thin-capped fibroatheromas of left main coronary artery and their changes after statin therapy.
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 mechani…
We sought to elucidate incidence, predictors, and effects of acute kidney injury after percutaneous aortic valve implantation.
A patient with hypertrophic cardiomyopathy who underwent alcohol septal ablation via the right radial artery approach and discussion of the technique are presented.
A 49-year-old female in cardiogenic shock required left ventricular assist device (LVAD) placement, but was not an optimal candidate for surgery due to severe deconditioning and malnutrition. Surgical implantation of an Impella 5.0 pump allowed time…
