ABSTRACT Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Intercoronary communication is a very rare subset with uni- or bidirectional blood flow between two or more coronary arteries. We present the case of a 70-year-old male patient with acute coronary syndrome, and his coronary angiography incidentally showed a surprising and very rare communication between the left circumflex and right coronary arteries.
ABSTRACT Background: Although much is known about the prognostic value of the GRACE risk score, there are few studies investigating how it relates with the angiographic complexity of coronary artery disease. For this reason, in this study, we aimed to assess the predictive capacity of the GRACE score in acute coronary syndrome in respect to the angiographic complexity based on the SYNTAX score. Methods: A cross-sectional study of patients with acute coronary syndrome undergoing coronary angiography during hospitalization, with at […]
ABSTRACT Mitral valve surgery has become an increasingly common procedure for patients with mitral valve disease. Iatrogenic coronary artery lesion has been reported as an uncommon and potentially fatal complication of mitral valve surgery. Its diagnosis must be considered during perioperative care, and coronary angiography helps in deciding the best therapeutic strategy. In the present clinical report, we describe a patient with iatrogenic occlusion of the left circumflex artery after surgery for mitral valve replacement due to rheumatic disease.
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 […]
ABSTRACT Optical coherence tomography is an intravascular imaging tool that has been increasingly used in the cardiac catheterization laboratory. Since its spatial resolution is approximately ten-fold greater than intracoronary ultrasound, optical coherence tomography assists in the anatomical differential diagnosis of coronary lesions with atypical presentation. In this report, we present a case of a female patient with a history of acute coronary syndrome and, currently, with a complex angiographic lesion, with the aspect of a chronic dissection in the anterior […]
ABSTRACT Background As the population ages, the prevalence of diseases has increased, particularly that of coronary artery disease requiring treatment. The objective of this study was to assess the temporal evolution of percutaneous coronary intervention in octogenarians in Brazil. Methods Based on data from the Central Nacional de Intervenções Cardiovasculares (CENIC), we analyzed procedures carried out in patients aged 80 years and over, from June 2006 to March 2016, classified into three time ranges: 2006-2008, 2009-2011 and 2012-2016. We assessed […]
ABSTRACT Background: The diagnosis of coronary artery disease is challenging because of the considerable variability in its clinical presentation. It also requires a cautious decision between invasive or conservative stratification. We aimed to evaluate the adequacy of coronary angiography indication in patients from the Unified Health System (SUS, in the Portuguese acronym) based on the guidelines for stable coronary disease. Methods: Consecutive patients who underwent coronary angiography between March 2014 and November 2015 were evaluated. Clinical presentation and functional tests […]
