Minimal dose CT for left ventricular ejection fraction and combination with chest-abdomen-pelvis CT.

Objectives: This prospective study tested the diagnostic accuracy, and absolute agreement with MRI of a low-dose CT protocol for left ventricular ejection fraction (LVEF) measurement. Furthermore we assessed its potential for combining it with Chest-Abdomen-Pelvis CT (CAP-CT) for a one-stop examination.

Materials & Methods: Eighty-two patients underwent helical low-dose CT.

[Cardiac CT].

Cardiac CT has become a frequently used diagnostic modality in Denmark, especially for the evaluation of coronary artery disease indicated by angina pectoris/dyspnoea. Indications have recently expanded to include evaluation of valvular heart disease, pre- and post-procedural evaluation related to several invasive procedures as well as some congenital and pediatric cardiac conditions. As described in this review, improved image quality and reduced radiation, owing to technological advances as well as a high number of well-performed scientific studies, have paved the way for this development.

The Western Denmark Cardiac Computed Tomography Registry: a review and validation study.

Background: As a subregistry to the Western Denmark Heart Registry (WDHR), the Western Denmark Cardiac Computed Tomography Registry (WDHR-CCTR) is a clinical database established in 2008 to monitor and improve the quality of cardiac computed tomography (CT) in Western Denmark.

Objective: We examined the content, data quality, and research potential of the WDHR-CCTR.

Methods: We retrieved 2008-2012 data to examine the 1) content; 2) completeness of procedure registration using the Danish National Patient Registry as reference; 3) completeness of variable registration comparing observed vs expected numbers; and 4) positive predictive values as well as negative predictive values of 19 main patient and procedure variables.

Which exercise test to use for chest pain from an anomalous coronary artery.

Chest pain in children and young people is a frequent cause of contact to general practitioners and outpatient clinics. However, in children, chest pain is typically benign and self-limiting; it is not usually a manifestation of organic disease, and it is very rarely of cardiac origin. The cause of chest pain often remains undiagnosed.
