Background Restrictive right ventricular (RV) physiology is a common finding after tetralogy of Fallot repair. Via diastolic ventricular interaction, RV filling characteristics may influence left ventricular (LV) filling. The aim…
Background The long-term risk of patients with Kawasaki disease is not well defined. A great proportion of patients with Kawasaki disease have important variation of their coronary artery (CA) diameters,…
Echocardiography has come a long way over the last 40 years, moving from an investigative tool that had little support from mainstream cardiology, to one that is considered essential in…
Background The acute and long-term effects of transcatheter aortic valve implantation (TAVI) in patients with aortic valve stenosis on left ventricular (LV) function are controversial. The aim of this study…
Background Clinical trials often rely on echocardiographic measures of left ventricular size and function as surrogate end points. However, the quantitative impact of factors that affect the reproducibility of these…
Background The two-dimensional (2D) proximal isovelocity surface area (PISA) method has some technical limitations, mainly the geometric assumptions of PISA shape required to calculate effective regurgitant orifice area (EROA). Recently…
Background Coronary flow reserve (CFR) is progressively impaired with aortic stenosis (AS) severity. However, there is a broad range of CFR in patients with severe AS, and the factors responsible…
Despite a small army of quantitative metrics, the accurate and reproducible assessment of mitral regurgitation (MR) severity can be a challenge for any echocardiographer. The proximal isovelocity surface area (PISA)…
The added value of transesophageal echocardiography (TEE) over transthoracic echocardiography in the assessment of left-sided infective endocarditis has been extensively validated in the literature. Little research has dealt with the…
