Ultrasound‐Based Z Score and Pulmonary Valve/Aortic Valve Diameter Ratio Improving the Predictive Value of Fetal Aortic Stenosis

open access: yesJournal of Clinical Ultrasound, EarlyView.
A total of 24 singleton fetuses with suspected AS who underwent two or more fetal echocardiograms were enrolled in this study. Using electronic spatiotemporal image correlation (eSTIC) technology, the AV and PV Z scores, along with the PV/AV ratio, were measured and compared between two echocardiographic examinations to assess diagnostic efficacy ...

4D Flow MRI Velocity and Turbulence Mapping in Mild Valvular Heart Disease

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Valvular heart disease (VHD) commonly leads to the development of turbulent blood flow. Turbulent kinetic energy (TKE), measured with 4D flow MRI, may be a complement to current metrics for early identification of VHD. Purpose To investigate TKE as a marker of VHD in relation to flow velocity and cardiovascular geometry.

Novel pathways of heart failure with preserved ejection fraction [PDF]

open access: yes, 2016
INTRODUCTION: Diastolic heart failure (HF) i.e., HF with preserved ejection fraction (HFpEF) accounts for ~50% of all clinical HF presentations; but unlike systolic HF i.e., HF with reduced ejection fraction (HFrEF), there are no evidenced based ...

Combining Detailed Fetal Anatomy Scanning in the NT Window Versus Early Second Trimester Scanning at 14–16 Weeks

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives First‐trimester ultrasound has evolved to incorporate a detailed fetal anatomy scan (FAS) with nuchal translucency (NT) screening. Many institutions use a 2‐visit protocol: NT followed by detailed FAS at 14–16 weeks. We aimed to evaluate whether integrating detailed FAS into the NT window (12 + 5 to 13 + 6 weeks) is non‐inferior in ...

Trans-esophageal echocardiography for tricuspid and pulmonary valves

open access: yesAnnals of Cardiac Anaesthesia, 2009
Transesophageal echocardiography has been shown to provide unique information about cardiac anatomy, function, hemodynamics and blood flow and is relatively easy to perform with a low risk of complications.
