Treatment of Calcified Complex PCI

     In cases where patients suffer from severe coronary artery stenosis combined with thick, hardened calcium deposits (Complex PCI), conventional balloon angioplasty may not be sufficient. Ramkhamhaeng Hospital utilizes modern technology to precisely break down calcification, enhancing treatment efficiency and reducing potential risks.

Complex PCI: Highly Effective Innovations for Vessel Preparation

• High-Speed Rotational Burr (Rotational / Orbital Atherectomy): An innovative small diamond-tipped burr that rotates at high speed to grind hardened calcium deposits into microscopic particles. This helps physicians clear the path and prepare the blood vessel for stent placement.
• Shockwave Lithotripsy Balloon or ‘Intravascular Lithotripsy – IVL’ : Technology that uses sonic pressure waves (Shockwaves) through a balloon to crack both superficial and deep calcium without damaging the vessel wall.
• Intravascular Imaging (IVUS / OCT) : Acting as the "eyes" of the physician, these provide real-time, high-resolution internal images of the vessel structure and calcium volume for the most precise treatment planning.
• Specialized Balloons: Including high-pressure (Non-compliant) balloons, scoring balloons, or cutting balloons designed to slice and crush calcium in difficult-to-reach areas.
• Specialized Guidewires: Navigation tools with excellent flexibility and torque control, allowing physicians to safely access highly complex lesions.

The Ultimate Goal for a Better Quality of Life

Physicians aim to use these specialized tools to "perfectly prepare the blood vessel" before stent placement.

• Full stent expansion
• Reduced risk of restenosis (recurring blockage)
• Enhanced efficiency and procedural safety
