Abstract

Background: Patent foramen ovale (PFO) is a major cause of cryptogenic stroke (CS). However, it is still possible that PFO comes with those other conditions during evaluation. This paper presents a series of CS cases highly suspected due to PFO origin with each of its special presentations. Case illustration/summary of a review article: We present three cases of CS with PFO as a possible contributing factor. Case 1 showed a patient with repeated ischemic strokes that was investigated to be cryptogenic in origin. Case 2 showed CS with PFO and occult atrial fibrillation. Case 3 showed CS at a young age caused by a PFO with protein C/S deficiency. Conclusion: The role of PFO as a culprit, risk factor, or a coincidental finding in CS is still debatable and is a controversial issue. Determining PFO as a cause of CS requires a thorough consideration of clinical and PFO anatomical/morphological factors.

Abstract

Background: Coronary artery disease (CAD) remains a leading cause of mortality, emphasizing the importance of early non-invasive diagnostic strategies. This study evaluated the diagnostic accuracy of coronary artery calcium scoring (CACS) in detecting significant coronary stenosis, using invasive angiography as the reference standard.   Methods: Sixty-three patients who underwent both CACS and quantitative coronary angiography were retrospectively analyzed. The mean total CACS was 684.1 ± 1030.8, and significant stenosis (≥70%) was most prevalent in the left anterior descending artery (92.1%).   Result: Spearman’s analysis revealed positive correlations between CACS and angiographic stenosis in the right coronary artery (ρ = 0.338, p = 0.007), left anterior descending artery (ρ = 0.492, p = 0.001), and left circumflex artery (ρ = 0.314, p = 0.012). Receiver operating characteristic (ROC) analysis demonstrated moderate-to-good diagnostic performance, with area under the curve (AUC) values of 0.699 for RCA, 0.769 for LAD, and 0.690 for LCX.   Conclusions: These findings indicate that CACS can serve as a reliable, low-cost, and non-invasive modality for preliminary screening and risk stratification of CAD, particularly in identifying patients who may benefit from invasive coronary angiography.
