INVASIVE AND INTERVENTIONAL TREATMENTS
Is a non-surgical procedure used to treat a narrowing (stenosis) of the coronary arteries of the heart found in coronary heart disease. A narrowing is due to the buildup of the cholesterol-laden plaques that form due to atherosclerosis. During angioplasty, a balloon is inserted into the narrowed artery using X-ray imaging as a guide. At the blockage, the balloon is inflated to open the artery, allowing blood to flow. A stent is often placed at the site of blockage to permanently open the artery.
Fractional Flow Reserve
Is a diagnostic interventional technique used during coronary angiograms to measure pressure differences across a coronary narrowing (stenosis) to determine the likelihood that the narrowing impedes oxygen delivery to the heart.
Intravascular Ultrasound (IVUS)
It uses a specially designed catheter with a miniaturised ultrasound probe attached to the distal end of the catheter. It allows the application of ultrasound technology to see from inside the coronary blood vessels. IVUS is used to determine both cholesterol-laden plaque volume within the wall of the artery and/or the degree of narrowing (stenosis) of the artery.
Transcatherer Aortic Valce Implant (TAVI)
TAVI is the non-surgical replacement of the aortic valve of the heart through the blood vessels. The replacement valve is delivered via one of several access methods: transfemoral (in the upper leg), transapical (through the wall of the heart), subclavian (beneath the collar bone), direct aortic (through a minimally invasive surgical incision into the aorta), and transcaval (from a temporary hole in the aorta near the belly button through a vein in the upper leg).
Is the widening of a narrowed valve using a balloon catheter inside the valve. The balloon is placed into the valve that has become stiff from calcium buildup. The balloon is then inflated in an effort to increase the opening size of the valve and improve blood flow.
Patent Foramen Ovale / Atrial Septal Defect / Venticular Septal Defect (PFO/ ASD/ VSD)
Typically known as a hole in the heart, is where there is a defect in the dividing wall (septum) of the heart. Device closure involves the passage of a catheter into the heart through the femoral vein guided by fluoroscopy and echocardiography. The closure device is guided through the septal wall via the defect and one disc of the closure device is opened and pulled into place. Once this occurs, the other disc of the closure device is opened in place on the other side of the septal wall, closing the defect.
Left Atrial Appendage Occlusion
Is a treatment strategy to reduce the risk of left atrial appendage blood clots from entering the bloodstream and causing a stroke in patients with atrial fibrillation. Left atrial appendage closure is an implant-based alternative to blood thinning medication.
Is a procedure where fluid is aspirated from the pericardium (the sac around the outside of the heart).
Is a catheter based procedure using radio frequency ablation or ultrasound ablation aimed at treating resistant hypertension (high blood pressure not controlled by medication). Nerves in the wall of the renal artery are ablated by applying radio frequency pulses or ultrasound to the renal arteries of the kidneys. This aims to disrupt neurogenic reflexes involved in blood pressure control.
