Background: Prediction of severity or complexity of coronary artery disease (CAD) is valuable owing to increased risk for cardiovascular events. Although the association between total coronary artery calcium (CAC) score and severity of CAD, Gensini score was not used, it has been previously demonstrated. There is no information about the association between total CAC score and complexity of CAD.
Objectives: To investigate the association between severity or complexity of coronary artery disease (CAD) assessed by Gensini score and SYNTAX score (SS), respectively, and coronary artery calcium (CAC) score, which is a noninvasive method for CAD evaluation in symptomatic patients with accompanying significant CAD.
Methods: Two-hundred-fourteen patients were enrolled. Total CAC score was obtained before angiography. Severity and complexity of CAD was assessed by Gensini score and SS, respectively. Associations between clinical and angiographic parameters and total CAC score were analyzed.
Results: Median total CAC score was 192 (23.0-729.8), and this was positively correlated with both Gensini score (r: 0.299, p<0.001) and SS (r: 0.577, p<0.001). At multivariate analysis, it was independently associated with age (ß: 0.154, p: 0.027), male gender (ß: 0.126, p: 0.035) and SS (ß: 0.481, p<0.001). Receiver-operating characteristic (ROC) curve analysis revealed a cut-off value>809 for SS>32 (high SS tertile).
Conclusion: In symptomatic patients with accompanying significant CAD, total CAC score was independently associated with SS and patients with SS>32 may be detected through high Agatston score.

Myocardial bridging is a frequent anomaly of the heart in humans and other animals. A myocardial bridge is typically characterized by the systolic narrowing seen with traditional catheter angiography, but this abnormality is not by itself a sign of ischemia or the need for intervention. In particular, transient spontaneous angina must be corroborated by reproducible narrowing during acetylcholine testing; this narrowing occurs during resting conditions and is responsive to nitroglycerin administration.

We report a case of spontaneous coronary dissection (SCAD) in a 32-year-old pregnant patient during the seventh month of her second pregnancy. A 32-year-old pregnant woman in the 28th week of gestation was referred to our intensive care unit because of angina as well as elevated troponin levels. The initial electrocardiogram and transthoracic echocardiogram (TTE) were normal.

Percutaneous coronary intervention (PCI) in pediatric patients is rare, especially in cases of chronic total occlusion (CTO) of the left main coronary artery (LMCA), with scarce evidence. These are associated with poorer prognostic outcomes, highlighting the need for timely intervention. In addition, its unique and entirely different pathophysiology compared to that well-studied in adults makes it a clinically challenging scenario for diagnosis, treatment, and follow-up.

Takotsubo syndrome or broken-heart syndrome is a rare form of nonischemic cardiomyopathy characterized by regional systolic dysfunction of the left ventricle without evidence of coronary artery disease or acute plaque rupture. This transient impairment in myocardial contractility leads to symptoms and signs that can mimic a myocardial infarction. We present a case of Takotsubo syndrome in a 47-year-old premenopausal woman with complex congenital heart disease who initially presented with acute onset of shortness of breath and chest tightness after a verbal altercation.

Coronary computed tomography angiography (CTA) analysis can help in the planning of percutaneous coronary intervention (PCI). Fractional flow reserve derived from coronary CTA (FFR), coronary CTA-derived regional myocardial mass, and FFR virtual PCI planner can facilitate decisions concerning sheath and guide catheter selection, stent lengths on the basis of predicted post-PCI FFR, optimal fluoroscopic angles, evaluation of provisional vs 2-stent bifurcation PCI techniques, and assessment of the magnitude of jeopardized myocardial mass in cases with side branch compromise. This case series illustrates the emerging opportunities for coronary CTA-based planning of bifurcation PCI.
