The upper pulmonary veins (PVs) are responsible for the majority of atrial fibrillation (AF) triggering foci, whereas the inferior PVs are more difficult to ablate and prone to postablation ostial ...
The study included healthy women aged 20–40 years with singleton pregnancies. Doppler ultrasonography was used to assess portal vein flow and velocity, complemented by standard laboratory tests to ...
A Transcranial Doppler (TCD) foaming test detected three emboli ... and ultimately the ophthalmic veins. The elevated pulmonary artery pressure leads to retrograde pressure affecting the right ...
Recent years have seen an enormous amount of experimental and clinical research into role of the pulmonary veins (PVs) in atrial fibrillation (AF). Advanced imaging techniques have confirmed the ...
A doctor may also order a Doppler test, also known as a duplex ultrasound. This test may help them grade the severity of a person’s varicose veins. Doctors may also check for signs of DVT during ...
Furthermore, multiple collateral vessels were observed, some of which ascended through the right hemidiaphragm to communicate with the pulmonary veins, which is consistent ... portal pressure ...
OBJECTIVE: The aim of this study was to evaluate the correlation between changes in the inferior vena cava collapsibility index and subclavian vein collapsibility index ... vena cava collapse index ...
