ABSTRACT Background: The treatment of coronary arteries with heavily calcified or chronically occluded lesions has the lowest success rates when they undergo a percutaneous procedure. A strategy to reduce the volume of calcified lesions, which was part of the rescue technique to treat non-balloon dilatable stenoses, has evolved to an approach of primary lesion preparation for subsequent stenting. Methods: This is a retrospective analysis of data related to rotational atherectomies performed in complex, high-risk patients, for treating extremely calcified lesions […]

ABSTRACT Since the advent of balloon angioplasty in 1977, countless tools and techniques have been introduced and broadened the application of percutaneous coronary intervention in unprecedented anatomic settings. Heavily calcified coronary lesions traditionally continue to pose a challenge for percutaneous coronary intervention, since they are difficult to dilate adequately and/or there is inability to deliver and deploy drug eluting stents appropriately. Poor stent deployment is associated with increased procedural complications and suboptimal long-term outcomes. Thanks to the introduction of dedicated […]

ABSTRACT Background: Calcified coronary lesions are a complex angiographic scenario in the practice of percutaneous coronary intervention. The objective of this article was to present the temporal trends of the clinical and angiographic profile, and in-hospital outcomes of patients with calcified lesions. Methods: A retrospective study of 35,897 patients with coronary calcification included in the Central Nacional de Intervenções Cardiovasculares (CENIC) registry, from January 2006 to January 2016. The temporal trends of clinical, angiographic and procedural variables, as well as […]
