In the Heart of Stiffness: Are Natural Heart Vibrations Reliable Enough to Assess Myocardial Stiffness, The New Holy Grail in Echocardiography?

Ultrasound techniques currently used in echocardiography are limited by conventional frame rates. Ultrafast ultrasound imaging is able to capture images at frame rates up to 100 times faster compared with conventional imaging. Specific applications of this technology have been developed and tested for clinical use in pediatric and adult cardiac imaging. These include ultrafast Doppler or vector flow imaging, shear wave imaging, electromechanical wave imaging, and backscatter tensor imaging. The principles of these applications are explained in this manuscript with illustrations on how these methods could be applied in clinical practice. Ultrafast ultrasound has great clinical potential in the assessment of cardiac function, in noninvasive hemodynamic analysis, while providing novel techniques for imaging coronary perfusion and evaluating rhythm disorders.

Ultrafast Ultrasound Imaging in Pediatric and Adult Cardiology: Techniques, Applications, and Perspectives.

Saving the endangered physician-scientists: reintroducing them to an environment of administrative support.

Symptomatic presentation of ductal arteriosus aneurysm is usually a consequence of associated complications, including thromboembolism, infection, and compression of adjacent structures. In this case report, we present a thrombosed ductal aneurysm that developed antenatally with further postnatal progression of the thrombus and complete occlusion of the left pulmonary artery. Urgent surgical thrombectomy was successful and the post-operative course was uneventful.

Antenatal occlusion of a ductal arteriosus aneurysm: a potential postnatal surgical emergency. Case report and literature review.

Myocardial Stiffness Assessment by Ultrasound: Are We Ready for the Clinical "Lift Off"?

Coronary artery disease affecting myocardial perfusion continues to be the leading cause of cardiovascular morbidity and mortality worldwide. While invasive evaluation based on coronary angiography and flow measurements still is considered the reference technique for assessing myocardial perfusion, technological evolutions in noninvasive imaging techniques resulted in them playing a more important role in assessing myocardial perfusion influencing therapeutic decision-making and prognostication.
