Computational μFR-Guided Versus Angiographic Guidance in Drug-Coated Balloon Angioplasty (MAGIC)

2026年10月29日 更新者:Centro Cardiologico Monzino

Computational μFR-Guided Versus Angiographic Guidance In Drug-Coated Balloon Angioplasty: a Randomized Controlled - Study MAGIC Trial

The MAGIC trial is an investigator-initiated, multicenter, randomized (1:1) interventional study designed to evaluate whether drug-coated balloon (DCB) angioplasty guided by computational μFR assessment is superior to conventional angiographic-guided DCB angioplasty in terms of acute physiological outcomes.

The study will enroll approximately 250 patients with de novo lesions in native coronary arteries with a reference vessel diameter (RVD) of 2.0-4.0 mm. Participants will be randomized to one of two treatment strategies.

In the angiography-guided control group, DCB angioplasty will be performed according to conventional angiographic criteria for an optimal procedural result, including TIMI grade 3 flow, residual stenosis of less than 30%, and absence of coronary artery dissections of type C or greater.

In the μFR-guided group, computational μFR will be assessed at baseline, after lesion predilation, and after DCB treatment. Virtual percutaneous coronary intervention (PCI) will be recommended to guide and optimize the angioplasty strategy, with the aim of achieving a final μFR value ≥0.86. If the physiological result remains suboptimal (μFR <0.86) despite further lesion preparation, a hybrid strategy involving implantation of a drug-eluting stent (DES) will be permitted.

The primary endpoint is the proportion of target vessels with a post-procedure μFR value ≥0.86, as assessed by an independent, blinded core laboratory through analysis of final coronary angiograms.

Clinical follow-up will be conducted exclusively by telephone over a total period of 24 months.

无干预:Angio-Based Group (Control)

In the angiography-guided control group, DCB angioplasty will be performed according to conventional angiographic criteria for an optimal procedural result, including TIMI grade 3 flow, residual stenosis of less than 30%, and absence of coronary artery dissections of type C or greater.

实验性的:μFR-Based Group (Intervention)

In the μFR-guided group, computational μFR will be assessed at baseline, after lesion predilation, and after DCB treatment. Virtual percutaneous coronary intervention (PCI) will be recommended to guide and optimize the angioplasty strategy, with the aim of achieving a final μFR value ≥0.86. If the physiological result remains suboptimal (μFR <0.86) despite further lesion preparation, a hybrid strategy involving implantation of a drug-eluting stent (DES) will be permitted.

Drug-coated balloon (DCB) angioplasty guided by computational μFR assessment. μFR is measured at baseline, after lesion predilation, and after DCB treatment. Virtual PCI based on μFR is recommended to guide lesion preparation and optimize the angioplasty strategy, targeting a final μFR value ≥0.86. If μFR remains <0.86 despite further lesion preparation, a hybrid strategy involving drug-eluting stent (DES) implantation is permitted.
