Perioperative cardiac events can be a major consequence of surgery. The American College of Cardiology Foundation/American Heart Association has set out guidelines to aid physicians in identifying patients at the highest risk for these events. The guidelines do recommend for some patients to undergo noninvasive cardiac stress testing for further risk stratification, but their sensitivity and specificity for predicting cardiac events is not optimal. With more data emerging of the superior performance of computed coronary tomography angiography (CCTA) compared to noninvasive stress testing, CCTA could be more useful in risk stratification for these patients.

The Quantification of Total Coronary Atheroma Burden – A Major Step Forward
Heart International. 2020;14(2):73-5 DOI: https://doi.org/10.17925/HI.2020.14.2.73
More than half of acute coronary syndromes (ACS) occur in subjects with no significant coronary stenosis.1 In view of the number of patients dying each year from a heart attack, the question of identifying these patients is of primary importance. A large body of evidence currently exists, indicating that total coronary atheroma burden (TOCAB) – the […]
Left main Stenosis Stenting Normalizes Wall Shear Stress of Ascending Aorta in Bicuspid Aortic Valve
Heart International. 2020;14(2):121-2 DOI: https://doi.org/10.17925/HI.2020.14.2.121
Bicuspid aortic valve (BAV) represents the most common congenital cardiac anomaly, with a prevalence ranging between 1% and 2% in the general population.1 BAV is known to be associated with dilation and dissection of the ascending aorta, and the significantly higher shear forces seem to have a pivotal role on the development of such complications.2 Nowadays, patients […]
Computed Tomography-Based Patients’ Specific Biomechanical and Fluid Dynamic Study of Anomalous Coronary Arteries with Origin from the Opposite Sinus and Intramural Course
Heart International. 2020;14(2):105-11 DOI: https://doi.org/10.17925/HI.2020.14.2.105
Anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) is one of the most clinically relevant abnormalities among the wide spectrum of coronary artery anomalies.1 Sudden cardiac death has been related to myocardial bridges, ectopic origin of the pulmonary artery, a single coronary artery and ACAOS with an intramural course (ACAOS-IM), especially in young […]
