Historically, chronic total occlusions (CTO) comprise the subgroup of the most difficult lesions to be treated by percutaneous techniques. CTO is one of the most important predictors of the need for coronary artery bypass grafting, of incomplete revascularization, and low success rates in attempts for percutaneous recanalization. In addition, CTO has been considered one of the factors associated with higher mortality rates in ST-segment or non-ST-segment elevation myocardial infarction patients. Many obstacles are faced when trying to perform target-vessel recanalization […]
ABSTRACT We describe the case of a patient with multiple comorbidities scheduled to undergo intracoronary optical coherence tomography-guided percutaneous coronary intervention. Based on the images acquired, it was possible to observe the mechanism of restenosis and the anatomy of the lesion, and to optimize planning of the procedure. Our strategy was to resect the neointimal hyperplastic tissue using laser atherectomy, with great results and a successful procedure.
ABSTRACT Transcatheter aortic valve replacement became a routine interventional procedure worldwide, together with improvements in valve technology and optimized implant techniques. The concept of minimalist approach became relevant, aiming at optimal technical implant, fewer perioperative comorbidities, and consequently faster recovery and less associated risks. Compared with surgical aortic valve replacement, reduction of hospital and intensive care unit stay and fewer rates of procedural complications offset the high costs of transcatheter aortic valve replacement valves. The principles of the minimalist approach […]
