“…METHODOLOGY AND PRINCIPAL FINDINGS: With a simple heart, a transparent body surface at larval stages and available genetic tools we chose Drosophila melanogaster as our model organism and developed for it a dual en-face/Doppler optical coherence tomography (OCT) instrument capable of recording multiple aspects of heart activity, including heart contraction cycle dynamics, ostia dynamics, heartbeat rate and rhythm, speed of heart wall movement and light reflectivity of cardiomyocytes in situ. …”

“…We believe that currently the presence of a BAV might not be considered an absolute contraindication for TAVI, because although there is no sufficient data for assess the safety or efficacy of TAVI in BAV, this case report shows that it could be performed safely in selected patients with unacceptable surgical risk after an extensive preoperative evaluation, avoiding this procedure in patients with bad prognostic factors as huge and heavy calcifications, asymmetric valves, elliptic annulus or small distance from leaflets to coronary ostia. Each case must be individualized, being alert at follow-up because the risk of late complications.…”

“…As iatrogenic coronary ostium occlusion is a potentially life-threatening complication, we evaluated the distances from the aortic annulus to the coronary ostia using RT3D-TEE. Based on our findings, we conclude that the geometry of the aortic root and aortic valve can be reliably and feasibly evaluated using RT3D-TEE, which is important for protecting against potential complications of TAVI, such as underestimation of the size of the aortic annulus that can result in aortic regurgitation and dislocation of the valve, or overestimation can lead to annulus rupture.…”

“…This sponge actively moves particle-trapping mucus against the direction of its internal water flow and ejects it into the surrounding water from its seawater inlet pores (ostia) through periodic surface contractions that have been described earlier as “sneezing.”(10)(,)(11) Visually, it appears as if the sponge is continuously streaming mucus-embedded particles and sneezes to shed this particulate waste, resulting in a notable flux of detritus that is actively consumed by sponge-associated fauna. …”
