چکیده

I n this issue of iJACC, Burris et al. (1) used a statewide registry to compare the diagnostic yield of coronary computed tomography angiography (CTA) with that of triple rule out (TRO) CTA scans and found that although there were slightly higher diagnostic yields for aortic dissection and pulmonary embolisms (PEs) in the TRO CTA group, this came at the cost of a higher dose of radiation and contrast exposure. This is the largest dataset to compare TRO CTA with coronary CTA and confirm the results of smaller studies and systematic reviews (2–5). However, as a comparative effectiveness study, the reader is unable to assess how clinicians decided which test to order or what institutional protocols existed. What disease or diseases were the clinicians trying to rule out? Why did they choose TRO CTA over a dedicated coronary CTA? Was it institutional protocol or provider choice? Furthermore, we do not know how many CTAs were done solely to evaluate for PE or aortic dissection.

Assessment of radiation-induced cancer risk to patients undergoing computed tomography angiography scans

Background: Computed tomography angiography (CTA) scan is a suitable imaging technique to evaluate the blood vessels. However, one major disadvantage is the potential risk of cancer related to ionizing radiation exposure during the procedures. The aim of this investigation was to estimate the risk of exposure induced cancer death (REID) values for some common computed tomography angiography (CT...

Cardiac Metastasis of Breast Cancer: A Case Report

Breast cancer is one of the most common cancers in women. As we know, cardiac metastases occur rarely. In this study, a 40-year-old woman referred to the hospital due to severe pain in the right leg. She was diagnosed with deep vein thrombosis (DVT) and received treatment, but, after one month and a half she returned with severe pain, exacerbated shortness of breath, cramping pain, and chest pa...
