ABSTRACT Spontaneous coronary artery dissection is defined as non-iatrogenic epicardial coronary dissection, not associated with atherosclerosis or trauma. Myocardial injury occurs due to coronary artery obstruction caused by intramural hematoma or intimal disruption, rather than atherosclerotic plaque rupture or intraluminal thrombus. We report a case of type 2 variant A spontaneous coronary artery dissection in the mid left anterior descending artery, presenting with type A Wellens’ syndrome, which required percutaneous coronary intervention for relief of refractory angina and pulmonary congestion.

ABSTRACT Fractional flow reserve has become the mainstay of functional hemodynamic assessment and is considered the gold standard to identify ischemic coronary stenoses. However, adopting the method into daily practice has been limited. Indeed, it requires the use of a costly pressure wire and the administration of a hyperemic agent. Vessel fractional flow reserve is a 3D-QCA based fractional flow reserve, using CAAS Workstation (version 8.4; Pie Medical Imaging, Maastricht, the Netherlands). It is a non-invasive method that does not […]

ABSTRACT Objective To assess the percentage of patients with normal coronary angiography in a hospital and to determine the predictor variables of this finding. Methods All elective coronary angiographies performed from April to October 2018 were analyzed, excluding patients with valve diseases and who had a previous catheterization. A total of 503 patients were recruited, divided into 2 groups: Group A for normal coronary arteries, and group B for coronary artery disease. Coronary vessels with diameter ≥2.0mm and with no […]

ABSTRACT Anomalous coronary arteries are rare conditions, especially when the origin of the right coronary artery comes from the trunk of the pulmonary artery. The manifestations of the disease can occur at an early stage, leading to sudden death, myocardial infarction or ischemic cardiomyopathy. Many reported cases have been asymptomatic for long periods. Surgery is always indicated as seen in most of the literature. We describe an angiographic case of an oligosymptomatic 76-year old patient referred for elective coronary angiography […]
