If the catheter passes from RV into the descending aorta, there could be VSD, PDA or AP window. Closed loop catheter position in PDA, open loop in others.
What is the phenomenon of pressure recovery in aortic stenosis? Phenomenon of pressure recovery in aortic stenosis: Systolic pressure in the aorta will be lower immediately distal to
Ventriculo-arterial pressure gradient It is usually the peak to peak gradient which is measured from pressure tracing during cardiac catheterisation, while Doppler echocardiography measures the peak instantaneous gradient.
Aortic pressure tracing vs femoral arterial pressure tracing Aortic pressure tracing vs femoral arterial pressure tracing: Upstroke and downstroke are sharper in a peripheral arterial pressure tracing compared
Black hole seen on IVUS in coronary restenosis Black holes are sonolucent areas within areas of restenosis seen on intravascular ultrasound. Regions near the IVUS catheter and towards
Instent restenosis after PCI Instent restenosis is often asymptomatic. One third of cases of instent restenosis can present with acute coronary syndrome and is sometimes quoted as an
