Optical coherence tomography (OCT) has become an established diagnostic technology in the clinical management of age-related macular degeneration (AMD). OCT is being used for primary diagnosis, evaluation of therapeutic efficacy, and long-term monitoring. Computer-based advances in image analysis provide complementary imaging tools such as OCT angiography, further novel automated analysis methods as well as feature detection and prediction of prognosis in disease and therapy by machine learning. In early AMD, pathognomonic features such as drusen, pseudodrusen, and abnormalities of the retinal pigment epithelium (RPE) can be imaged in a qualitative and quantitative way to identify early signs of disease activity and define the risk of progression...

We report on two cases in which Y-shaped coronary bifurcations were treated with the use of Bioresorbable scaffolds. The first case was of a 50-year-old man with NSTEMI. Coronary angiography showed stenosis involving a Y-shaped bifurcation of proximal to mid LAD and diagonal. The lesion was wired using two 0.14 BMW guide wires, followed by serial pre-dilatation of LAD and Diagonal branch. The stent into proximal LAD was deployed first as a skirt (3.5 × 12 BVS). Stent was post-dilated. A second 2.5 × 28 BVS was deployed into diagonal branch, protruding backwards; along with a 2...
