Care from one of UK's finest
I perform the following invasive investigations and interventions:
- Coronary angiography
- Right and left heart catheterisation
- Pressure wire assessment of coronary arteries (FFR AND iFR)
- Intravascular ultrasound assessment of coronary arteries with virtual histology
- Optical Coherence tomography assessment of coronary arteries
- Rotational atherectomy (rotablation)
- Coronary angioplasty and stenting
- Implantation of Bioresorbable vascular scaffold systems in coronaries
Commonly used devices in patients undergoing PCI
Intravascular Ultrasound (IVUS)
IVUS is a catheter based system which allows us to obtain ultrasound images from within the coronary artery.
Its main application is in complex lesions to ensure that a stent has been adequately deployed and expanded after a PCI procedure.
This is a wire with a pressure sensor close to its tip. It is used to obtain measurements of pressure differences across a narrowing in the coronary artery.
The decision to perform PCI is usually based on the angiogram. However in some cases the pressure wire is used to obtain the functional severity of a narrowing in the coronary arteries by understanding the pressure drop across a stenosis.
Rotational Atherectomy (Rotablation)
This is a rotating diamond tipped drill (160,000 rotations per minute) which is used to treat coronary arteries with hard calcium deposits. The rotating burr grinds up the calcified plaque and then enables a balloon and stent to expand fully and treat the narrowings in a coronary artery.
