The Angiography Heart it has positioned itself as one of the studies of the first line for assessment of coronary artery disease, atherosclerosis, playing a role in the evaluation of congenital anomalies of the coronary arteries, as well as the degree of stenosis of the same. In recent years, it has gained the use of the flow of fractional reserve tomography to assess the severity of the stenosis and its hemodynamic impact.
The advent of ct 128-and more cuts has revolutionized this technique, because it can suppress extrasístoles, edit the electrocardiogram, and in this way be able to acquire the data with higher frequencies of which we were using.
The Angiography Heart is not only used in studies of intermediate-risk, but that it is also useful to rule out chest pain is typical, but without electrocardiographic changes or enzymatic final of coronary heart disease in the emergency room, decreasing the time spent in emergency and reducing the amount of angiographic studies of conventional unnecessary.
It is also indicated for the evaluation of congenital disease heart in children and in adults, such tetralogías of Fallot, such as single ventricle, common core, patent ductus arteriosus persistent, atresia or pulmonary stenosis, among others, demonstrating clarity and high temporal and spatial resolution of the anatomical alterations of the heart and blood vessels.
This study has a very short duration of few seconds, performed triggered to the electrocardiogram and the advent of machines faster, have made it possible to reduce both the radiation and the amount of contrast medium. In children it can be performed even with frequencies of up to 150 lpm.
Angiography Heart in a patient that query-by-blow holo systolic and shortness of breath. Note:
(A) Fistula coronary artery from the trunk of the left coronary with glass tortuous and elongated, ending in the trunk of the pulmonary artery.
(B) Artery fistula of the cone that ends in the fistula described previously in the trunk left. Rest of normal coronary arteries. Increase of right chambers.
