ABSTRACT Excimer Laser coronary atherectomy has improved significantly in recent years, emitting high-energy ultraviolet and short wavelength with less penetration and heat emission, ultimately leading to less tissue damage and fewer complications. We described a case of a 66-year-old male patient, former smoker and suffering from hypertension, diabetes mellitus, and dyslipidemia. He underwent multiple percutaneous coronary interventions in the left anterior descending artery with bare metal and drug-eluting stents. In the last percutaneous coronary intervention, the stent was underexpanded and […]

ABSTRACT Currently, percutaneous coronary interventions account for more than 80% of myocardial revascularization procedures. This result was enabled by two major advances: the development of effective and safe drug-eluting stents, in addition to a potent and effective antithrombotic pharmacotherapy in the prevention of atherothrombotic events, which, in general, should be maintained for about 6 to 12 months after the index intervention. However, a significant number of cases (up to 20% of treated patients according to literature) are at risk for […]

ABSTRACT Background: Significant lesions in the left main coronary artery are found in approximately 5% of patients undergoing coronary angiography, with most cases involving multiple vessels and affecting the distal bifurcation. A coronary artery bypass graft surgery is considered the preferred treatment for unprotected left main coronary artery lesions. However, with the advancement of techniques and the introduction of new drug-eluting stents, percutaneous coronary intervention has been considered a viable strategy, with favorable results. The objective of this study was […]

ABSTRACT The widespread use of bare metal stents as from 1995 led to the appearance of a new entity called in-stent restenosis, and the severe concomitant calcification of the vessels is a challenge for the interventional cardiologist. In this scenario, rotational atherectomy has rised as a therapeutic rescue approach to manage this situation, using trephines to eliminate the underexpanded and non-expandable coronary stents. However, comprehensive data on the long-term efficacy or results of the procedures have not been published yet. […]

ABSTRACT Background The opportunity for percutaneous treatment of coronary artery disease in unprotected left main artery has increased. This treatment possibility is based on favorable results in the literature. The objective of this study was to compare the demographic profile and results of percutaneous coronary intervention in patients with unprotected left main coronary artery lesions. Methods The period from 2006 to 2016 was analyzed, divided into three intervals – 2006 to 2008, 2009 to 2011 and 2012 to 2016, based […]

ABSTRACT Anomalous coronary arteries are rare. The origin of the left main coronary artery from the right sinus of Valsalva is related to some events, such as syncope, arrhythmias, angina, among others. By and large, its diagnosis is incidentally made by coronary angiography. The presence of this type of anomaly may hinder percutaneous approach of the coronary lesions. The authors describe a case of left main coronary artery originating from the right sinus of Valsalva, associated to disease of multiple […]
