Comparison of Adaptive Optics Scanning Light Ophthalmoscopic Fluorescein Angiography and Offset Pinhole Imaging [PDF]

, 2014
Recent advances to the adaptive optics scanning light ophthalmoscope (AOSLO) have enabled finer in vivo assessment of the human retinal microvasculature. AOSLO confocal reflectance imaging has been coupled with oral fluorescein angiography (FA), enabling

Management of Lost Atherectomy Devices in the Coronary Arteries

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Rotational and orbital atherectomy are important tools to treat calcific coronary disease. Entrapment of an atherectomy device, that is, rotational atherectomy burr or orbital atherectomy crown, is a serious complication during atherectomy. Loss of an atherectomy device is a more challenging complication that usually follows device entrapment.

Minimum Lumen Area Indexed to Left Ventricular Mass to Identify Functionally Significant Left Main Coronary Stenoses

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aim Diagnosing significant left main coronary artery (LMCA) stenoses based on anatomical criteria remains challenging. The ARMYDA FINISH multicenter study evaluated whether indexing intravascular ultrasound (IVUS)‐derived minimum lumen area (MLA) provides greater diagnostic accuracy than unindexed MLA for detecting ...
