Importancia de la cuantificación del flujo coronario mediante PET, en pacientes con enfermedad trivascular

The study of patients with coronary artery disease by means of gated SPECT has been well established. One of the major limitations of this technique is the detection of myocardial perfusion defects in the presence of multivessel or three-vessel coronary artery disease due to balanced ischemia. Quantification of myocardial blood flow by positron emission tomo graphy allows not only to study cardiac perfusion and function but also to determine the coronary flow reserve which has a better correlation with significant stenosis in patients with trivascular disease. The aim of this study was to demonstrate through a case report and literature review the importance of performing quantification of coronary blood flow in this group of patients.
