Although emerging data support the utility of real-time three-dimensional echocardiography (RT3DE) during dobutamine stress testing, the feasibility of performing contrast enhanced RT3DE during exercise treadmill stress has not been explored. Two-dimensional (2D) and three-dimensional (3D) acquisition were performed in 39 patients at rest and peak exercise. Contrast was used in 29 patients (74%). Reconstruction was performed manually by generating short axis cut planes at the base, mid-ventricle and apex, and automatically by generating 9 short axis slices. Three-dimensional acquisition was feasible during rest and stress regardless of the use of contrast. Time to acquire stress images was reduced using 3D (35.2±17.9 s) as compared to 2D acquisition (51.6±14.7 s; P<0.05). Using a 17-segment model, of all 663 segments, 588 resting (88.6%) and 563 stress segments (84.9%) were adequately visualized using manually reconstructed 3D data, compared with 618 resting (93.2%) and 606 stress segments (91.4%) using 2D data (P rest=0.06; P stress=0.07). We concluded that contrast enhanced RT3DE is feasible during treadmill stress echocardiography.

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 […]
