About this study

Official title: Drug Coated Balloons Versus Drug-Eluting Stents for Severe Coronary Calcification After Optimal Calcium Modification Assessed by QFR (PRECISE CAL Study)

The goal of this clinical trial is to learn if the short and long term effect of drug coated balloon (DCB) is non-inferior to drug eluting stent (DES) in patients with severe coronary calcification after optimal calcium modification assessed by quantitative flow ratio (QFR). The main questions it aims to answer are:

  1. Researchers will compare to see if DCB is non-inferior to DES when evaluated by major cardiovascular adverse events (MACE) one year after percutaneous coronary intervention (PCI).
  2. Researchers will compare to see if the perioperative cardiovascular events is different between DCB and DES treated lesions.
  3. Researchers will compare to see if the QFR is different between DCB and DES treated lesions one year after PCI.

Participants with severe coronary calcification diagnosed by coronary angiography or intravascular ultrasound (IVUS) will receive calcium modification through rotational atherectomy (RA), excimer laser coronary angioplasty (ELCA), or intravascular lithotripsy (IVL). Then, QFR will be measured based on angiographic image. QFR >0.8 will be defined as optimal calcium modification and patients will be randomized 1:1 to DCB or DES treated groups. Telephone follow-ups will be conducted at 1 month, 6 months after PCI and .angiophraphy follow-up will be performed at 12 months after PCI.

Read the detailed description

Perioperative cardiovascular events include side branch loss, coronary perforation, no-reflow/slow flow, and perioperative myocardial infarction defined as an elevation of cardiac markers (cTN or CK-MB) greater than 5 times the upper limit of normal.

Definite or probable thrombosis in DCB or DES treated vessels will be documented.

After randomization, if a dissection with restricted blood flow occurs after DCB treatment, DES will be implanted.

Being tested
rotational atherectomy (RA), excimer laser coronary angioplasty (ELCA), Intravascular Lithotripsy (IVL)
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rotational atherectomy (RA)Device

    Rotational atherectomy (RA) is a procedure that uses a diamond-coated, high-speed rotating burr to shave and remove calcified plaque from coronary arteries

  • excimer laser coronary angioplasty (ELCA)Device

    Excimer laser coronary angioplasty (ELCA) is a minimally invasive procedure that uses pulses of ultraviolet light to vaporize plaque in a blocked coronary artery. The procedure involves inserting a catheter with a laser fiber optic tip into an artery in the groin or arm, guiding it to the blockage using X-ray guidance, and then using the laser to ablate the plaque and improve blood flow.

  • Intravascular Lithotripsy (IVL)Device

    An IVL catheter with emitters is inserted into the artery, and it delivers pulsatile shock waves to crack the calcium, which then allows for a balloon or stent to be safely expanded to restore blood flow.
