DCB vs DES for Severe Coronary Calcification After Optimal Modification Assessed by QFR

Официальное название

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

Обзор

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.

Подробное описание

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.

Вмешательства

• Устройство rotational atherectomy (RA)
  Rotational atherectomy (RA) is a procedure that uses a diamond-coated, high-speed rotating burr to shave and remove calcified plaque from coronary arteries
• Устройство excimer laser coronary angioplasty (ELCA)
  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.
• Устройство Intravascular Lithotripsy (IVL)
  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.

Первичные конечные точки

• Number of participants with MACE as defined by cardiovascular death, target lesion revascularization, non-fatal stroke, target vessel non-fatal myocardial infarction. [Срок оценки: One year after treatement.]

Вторичные конечные точки (2)

• 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. [Срок оценки: From treatment to hospital discharge]
• QFR at one year post PCI [Срок оценки: one year after treatment]
