Practicality, safety and accuracy of computed tomography coronary angiography in the evaluation of low TIMI-risk score chest pain patients: A pilot study

Objectives:  The present pilot study aimed to assess the practicality, safety and accuracy of performing CT coronary angiography (CT‐CA) in the evaluation of acute chest pain of patients with low thrombolysis in myocardial infarction (TIMI) risk scores.

Non‐invasive computed tomography angiography in the assessment of coronary stent patency: an Australian experience

Background: This study aimed to evaluate the feasibility and accuracy of 16‐slice computed tomography (CT) in the assessment of coronary stent patency. CT coronary angiography (CA) has a high degree of accuracy in the assessment of coronary artery disease compared with invasive selective CA. However, its accuracy in the evaluation of stent patency is not well investigated.

Non‐invasive multislice computed tomography coronary angiography for imaging coronary arteries, stents and bypass grafts

Multislice computed tomography (MSCT) is evolving rapidly and available data suggest that MSCT coronary angiography may be a reliable and accurate non‐invasive imaging modality of coronary arteries. Current generations of MSCT scanners have high sensitivity and specificity for diagnosing native coronary artery disease and coronary bypass graft occlusion. The performance of MSCT in the evaluation of stent patency is still being assessed. In comparison with conventional selective coronary angiography (SCA), MSCT is non‐invasive, cheaper and it has the advantages of imaging plaque compositions as well as assessment of luminal patency. Nevertheless, the role of MSCT in the management of coronary artery disease is yet to be fully defined.

Multislice CT to evaluate coronary stent patency: a case report.

This is a case report on the ability of 16‐slice computed tomography in assessing the patency of coronary stent and diagnosing an asymptomatic stenotic lesion with soft plaque morphology. These findings were confirmed with a selective coronary angiography. Identification of lesion morphology facilitated our decision on prophylactic and direct stenting to the lesion.

Negative coronary CT angiography for chest pain assessment predicts low event rate in 5 years

Introduction: Coronary CT angiography (CTA) is becoming a popular investigation for chest pain. A negative coronary CTA is known to have a good negative predictive value for major adverse cardiovascular events in short term. The data on the long‐term outcomes of negative coronary CTA are lacking. We aim to investigate the long‐term prognostic value of negative coronary CTA in the evaluation of chest pain.
