CHIP Angioplasty refers to complex, high-risk coronary interventions performed in patients with severe or advanced heart disease who are not ideal candidates for routine angioplasty or surgery.
What is CHIP Angioplasty?
CHIP stands for Complex High-Risk Indicated Percutaneous Coronary Intervention. These procedures are done in critically ill, elderly, or high-risk patients who often have:
Severely calcified arteries
Multiple blockages or left main disease
Poor heart function (low ejection fraction)
History of failed bypass surgery (CABG) or inoperable disease
Chronic total occlusion (CTO) of coronary arteries
What makes it different?
CHIP angioplasty goes beyond standard procedures by using advanced tools and techniques, such as:
Rotational atherectomy (ROTA)
Intravascular Lithotripsy (IVL)
Intravascular Ultrasound (IVUS)
Mechanical circulatory support (e.g., Impella, IABP) if needed
Benefits:
Offers life-saving treatment to patients deemed too high-risk for surgery
Provides a less invasive option compared to bypass surgery
Improves quality of life and heart function in patients with limited options
