Acute Chest Pain of Coronary Origin in Patients without Diabetes: How Multidetector Computed Tomography (MDCT) Angiography Helps in Diagnosis.

BACKGROUND: To assess the diagnostic value of MDCT coronary angiography for evaluation of acute chest pain of coronary origin in non-diabetic patients. MATERIAL/METHODS: In 22 patients without DM, we assessed coronary arteries with multidetector CT angiography and invasive conventional angiography. RESULTS: CT coronary angiography revealed positive coronary artery disease findings in 16 patients; LAD was affected in 16 (72.3%), RCA in 14 (63.3%), and LCX in 8 (36.4%) cases. The proximal part of LAD was the most commonly affected coronary artery (14 cases, 63.3%) in the studied patients who underwent MSCT coronary angiography. As regards the calcium score, 4 patients (18%) had low calcium scores, 6 cases (27%) had moderate calcium scores, and 12 cases (55%) had high calcium scores. There were 6 patients with positive findings of coronary artery disease detected on MDCT coronary angiography that were not mirrored by conventional angiography. CONCLUSIONS: MDCT angiography of the coronaries is a good and rapid method for evaluation of the coronary anatomy and for early detection and grading of coronary lesions in non-diabetic patients.

Multidetector Computed Tomography (CT) in Evaluation of Congenital Cyanotic Heart Diseases.

BACKGROUND: The aim of the study is to emphasize the role of 128 MSCT angiography in the diagnosis of congenital cyanotic heart diseases. MATERIAL/METHODS: This study included sixty patients and was conducted from December 2014 to July 2016 in the Multidetector CT unit of Zagazig University hospitals. All images included axial, MPR, MIP, and VRT and were interpreted in one session. Pulmonary veins were assessed for PAPVR or TAPVR, PDA, cardiac apex and heart chambers, interatrial or interventricular septal defects, pericardium, and site and size of the great veins (IVC and SVC). RESULTS: This study included 60 patients. Thirty-four were boys (56.7%), and 26 were girls (43.3%). The age ranged from nine months to five years, and the mean age was 34.5 months. We found the following anomalies: tetralogy of Fallot (15 patients, 25%), tricuspid atresia (12 patients, 20%), Ebstein's anomaly (4 patients, 6.5%), pulmonic atresia or stenosis (7 patients, 11.5%), truncus arteriosus (6 patients, 10%), TGA (10 patients, 17%), and TAPVR (6 patients, 10%). CONCLUSIONS: MDCT proved to be an important modality for decision-making in patients with congenital cyanotic heart diseases.
