Initial experience with orbital atherectomy in a non-surgical center in Portugal
Faria, Daniel; Vinhas, Hugo; Bispo, João; Guedes, João; Marto, Sandrine; Palmeiro, Hugo; Franco, Patrícia; Mimoso, JorgeIntroduction and objectives: Percutaneous coronary intervention (PCI) of severely calcified lesions is associated with a higher risk of procedural complications, suboptimal stent expansion, and in-stent restenosis. Lesion preparation with orbital atherectomy (OA) in severely calcified lesions has been shown to increase procedural success and decrease reintervention rates. In this study, we sought to report the ...
Clinical results of percutaneous coronary intervention in chronic total occlusi...
Costa, Hugo; Espirito-Santo, Miguel; Bispo, João; Guedes, João; Mimoso, Jorge; Palmeiro, Hugo; Gonçalves, Rui Baptista; Vinhas, HugoIntroduction and Objectives: Coronary chronic total occlusions (CTOs) of the right coronary artery (RCA) are a relatively common finding in the context of coronary angiography. However, the benefit of revascularization remains controversial. Methods: A single -center retrospective cohort analysis prospectively collected outcomes of CTO patients undergoing percutaneous coronary intervention (PCI) in 2019 and 202...

Costa, Hugo; Espírito-Santo, Miguel; Bispo, João; Guedes, João; Mimoso, Jorge; Palmeiro, Hugo; Gonçalves, Rui Baptista; Vinhas, HugoIntroduction and Objectives: Coronary chronic total occlusions (CTOs) are relatively common findings in patients with type 2 diabetes mellitus (T2DM). However, the indication for percutaneous coronary intervention (PCI) and its clinical benefit in these patients remain controversial. Methods: A single-center retrospective cohort study with prospectively collected outcomes was carried out with CTO patients under...
Ionizing radiation exposure in complex percutaneous coronary intervention: Defi...
Costa, Hugo; Espírito-Santo, Miguel; Bispo, João; Guedes, João; Paulo, Graciano; Mimoso, Jorge; Palmeiro, Hugo; Gonçalves, Rui Baptista; Vinhas, HugoIntroduction and objectives: Concerns regarding the consequences of ionizing radiation (IR) have been increasing in the field of interventional cardiology (IC). There is little information on reported national and local radiation diagnostic reference levels (DRLs) in catheterization laboratories in Portugal. This study was designed to assess the IR dose exposure during complex percutaneous coronary intervention...
Ichthyofauna assemblages from two unexplored Atlantic seamounts: Northwest Bank...
Monteiro, Pedro; Ribeiro, Daniel; Silva, José A.; Bispo, João; Gonçalves, J. M. S.Underwater censuses by divers were used to study the fish assemblages from two unexplored Atlantic seamounts in the Cape Verde archipelago. Fifty three species of 27 families were recorded: 27 in Northwest Bank and 46 in João Valente Bank. Northwest Bank had dense schools, while João Valente Bank had higher species richness and smaller schools. Both seamounts were dominated mainly by coastal species directly de...
Underwater survey of ichthyofauna of eastern Atlantic seamounts: Gettysburg and...
Gonçalves, J. M. S.; Bispo, João; Silva, José AugustoGettysburg and Ormond are seamounts belonging to the Gorringe Bank, which is located on the Europen-African plate boundary. Given the importance of these oceanic features for understanding marine biodiversity patterns, two surveys were carried out in 1998 (Gettysburg) and 1999 (Ormond) using diving, photography and video for species identification and abundance evaluation. Of the 9 fish species found at Gettysb...
