Diagnostic accuracy of coronary ct for the quantification of the syntax score in patients with left main and/or 3-vessel coronary disease. Comparison with invasive angiography

Commentary to the article “Coronary computed tomography angiography for the assessment of SYNTAX score”

“…Therefore, we can assume that the population with extensive coronary calcifications is under-represented in this study, and the reliability of CCTA for estimation of the SYNTAX score could be lower in cases with severe calcification in the coronary tree. Other studies also reported inferior agreement coefficients between ICA and CCTA in cases with high SYNTAX scores [3]. Invasive coronary angiography could remain, in our opinion, a superior method to estimate the severity of coronary lesions based on the SYNTAX score in cases with heavy calcifications of the coronary artery walls.…”

Prognostic value of SYNTAX score based on coronary computed tomography angiography

“…Only a small number of studies have reported the feasibility and reproducibility of the CT-based SYNTAX score, using the ICA-based SYNTAX score as a reference standard [5,7,13,26,27]. These studies focused on the comparison of the CT-based SYNTAX score with the ICAbased SYNTAX score.…”

“…The SYNTAX score calculated based on invasive coronary angiography (ICA) is an independent predictor of major adverse cardiac events (MACEs) in populations with a varying extent of CAD [4], and the values derived from this scoring system can be helpful when determining the optimal revascularization strategy. Although the SYNTAX score was originally based on ICA, recent publications have suggested coronary computed tomography (CCTA) as a feasible modality for estimating the SYNTAX score [5][6][7]. However, the long-term prognostic value of the CT-based SYNTAX score has not yet been investigated.…”

Impact of Diabetes Duration on the Extent and Severity of Coronary Atheroma Burden in Type 2 Diabetic Patients : Evaluation by Coronary CT Angiography

“…For each patient, the number of diseased vessels was calculated through the assignation of one, two, three, or LM coronary artery vessels. The extent and severity of CAD burden were measured by several coronary CT angiographic scores, including coronary artery calcium score (CACS), atheroma burden obstructive score (ABOS), segment involvement score (SIS), segment stenosis score (SSS) and syntax score [13,14] .…”

“…The Syntax score was derived from the summation of the individual scores for each separate lesion defined as ≥50% luminal obstruction in vessels ≥ 1.5 mm. The syntax scores were calculated for all previous patients using dedicated software [12,14] .…”
