Complex coronary angioplasty is used for selected difficult coronary artery blockages, including long, heavily calcified or anatomically challenging lesions. Advanced techniques and imaging may help guide treatment. The choice depends on coronary anatomy and patient risk.
Optical coherence tomography uses near-infrared light to obtain detailed images of coronary artery structures. It may assist with assessing plaques, selecting treatment strategies and evaluating stent placement during selected coronary interventions.
Intravascular ultrasound uses a catheter-mounted ultrasound probe to visualise coronary artery walls. The information can help assess vessel size, plaque characteristics and stent expansion during selected angioplasty procedures.
Intravascular lithotripsy uses controlled acoustic pressure waves to modify selected calcified arterial lesions. It may help prepare heavily calcified blood vessels for further catheter-based treatment. Suitability depends on vessel characteristics.
Orbital atherectomy is a catheter-based technique used to modify selected calcified coronary artery plaques. It may be considered during complex coronary interventions when calcium affects the ability to expand balloons or stents effectively.
Transcatheter aortic valve implantation is a minimally invasive procedure used for selected patients with severe aortic valve stenosis. A replacement valve is delivered through a catheter. Eligibility depends on valve anatomy, symptoms and multidisciplinary assessment.
Impella is a temporary mechanical circulatory support device used in selected high-risk cardiac procedures or serious circulatory conditions. It helps support blood flow while the heart is under stress. Use depends on clinical criteria and availability.
Heavy calcium within coronary arteries can make catheter-based procedures more challenging. Specialist assessment may involve intravascular imaging and plaque-modification techniques before stent placement. Treatment is tailored to coronary anatomy.
Complex coronary artery disease may involve multiple blockages, difficult vessel anatomy or previous cardiac procedures. Management requires detailed assessment and may include medication, advanced angioplasty or referral for bypass surgery.
Some patients with heart failure require specialised interventions in addition to medication. Assessment considers heart function, symptoms, structural abnormalities and associated coronary disease. Treatment options depend on the underlying condition and patient characteristics.
