Aortic regurgitation (AR) is characterized by diastolic reflux of blood from the aorta into the
left ventricle (LV). Acute AR typically causes severe pulmonary edema and hypotension and …

Intraoperative (IO) transesophageal echocardiography (TEE) is widely used for assessing
the results of valvular heart disease (VHD) surgery. Epiaortic ultrasonography (EAU) has …

Aortic regurgitation (AR) is a known complication of discrete subvalvar aortic stenosis (DSS),
and its detection often triggers referral for surgery. However, risk factors for aortic valve …

Basic Transesophageal and Critical Care Ultrasound provides an overview of
transesophageal ultrasound of the heart, lung, and upper abdomen as well as basic …

Objective: More than a decade before the introduction of intraoperative transesophageal
echocardiography (TEE), epicardial echocardiography was already in use as a diagnostic …

Objectives: To identify functional aortic regurgitation (FAR) determinants in patients with
ascending thoracic aortic aneurysm (ATAA) and surgically confirmed normal aortic valve …

BACKGROUND: Noninvasive quantitation of valvular regurgitation remains a difficult
problem. Measurements of the vena contracta (VC) by color Doppler echocardiography …

Background: The aim of our study was to determine whether planimetry of the anatomic
regurgitant orifice (ARO) in patients with aortic regurgitation (AR) by magnetic resonance …

Background Quantitation of aortic regurgitation (AR) using two-dimensional (2D)
echocardiography, including vena contracta width (VCW) measurement, is still challenging …

Aortic regurgitation (AR) is a common valvular heart disease, but the optimal timing of
surgical intervention remains controversial. In the natural history of chronic severe AR …
