I read with interest the article “Exercise Echocardiography Demonstrates Biventricular Systolic Dysfunction and Reveals Decreased Left Ventricular Contractile Reserve in Children after Tetralogy of Fallot Repair” by Roche et al ….
Background Transcatheter aortic valve implantation (TAVI) is an alternative therapy for high-risk patients with symptomatic aortic stenosis. TAVI without balloon aortic predilation (BPD) has been found to be as feasible…
Background Aortic valve calcification (AVC) without stenosis is common in the elderly, is associated with cardiovascular morbidity and mortality, and may progress to aortic valve stenosis. Arterial stiffness and pulse-wave…
Background With the advent of three-dimensional (3D) printers and high-resolution cardiac imaging, rapid prototype constructions of congenital cardiac defects are now possible. Typically, source images for these models derive from…
Background There is significant disparity in the reported incidence of moderate and severe paravalvular aortic regurgitation (PAR) between the Placement of Aortic Transcatheter Valves (PARTNER) I and PARTNER II trials,…
“If I could touch anything in the world right now, it would be your heart. I want to take that piece of you and keep it with me.” The technology…
Few resources exist to educate cardiac sonographers regarding proper techniques and specific issues to consider when performing pediatric coronary artery imaging. The main objective of this report is to review…
Background Left ventricular (LV) ejection fraction (EF) is a routine clinical standard to assess cardiac function. Global longitudinal strain (GLS) and global circumferential strain (GCS) have emerged as important LV…
Tasneem Z. Naqvi, MD Despite implementation of risk factor-based screening, deaths due to cardiovascular disease (CVD) continue to rise. The majority of CVD deaths occur in those with low to…
Background On the basis of the electromechanical coupling theory, an activation imaging system has been developed with three-dimensional speckle-tracking echocardiography. The aim of this study was to determine the association…
