What does this research mean for the field?

Rotational atherectomy and advanced balloon-based strategies improve minimal stent area compared to standard noncompliant balloons during percutaneous coronary intervention for calcified lesions, but these mechanical improvements do not translate to better clinical outcomes. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess the comparative efficacy and safety of different calcium-modification strategies in patients undergoing percutaneous coronary intervention for calcified coronary lesions.

September 1, 2026Cardiovascular TherapeuticsOpen Access

Calcium modification increases MSA by ~0.81 mm2 over noncompliant balloons without improving clinical outcomes.

Q: What is the clinical evidence from this study?

Study design: Meta-Analysis. Population: calcified coronary lesions (n=4855). Intervention: Calcium-modification strategies (e.g., cutting/scoring balloon, intravascular lithotripsy, rotational atherectomy) vs. Standard noncompliant balloons. Primary outcome: minimal stent area (MSA) (MD 0.81, 95% CI 0.36-1.27, p=0.001).

Why the study?

Calcified coronary lesions increase PCI failure risk, and comparative investigations among available calcium-modification strategies remain scanty despite several randomized trials.

Do advanced calcium-modification strategies improve minimal stent area compared to standard noncompliant balloons in patients undergoing PCI for calcified coronary lesions?

Comparison

Different calcium-modification strategies compared to noncompliant balloons

Design

Random-effects network meta-analysis of randomized trials

Key result

Compared to noncompliant balloons, calcium-modification strategies like cutting/scoring balloons increased minimal stent area (MD 0.81 mm2; 95% CI 0.36-1.27; p=0.001), but did not improve clinical outcomes.

Overview

Advanced calcium modification increases stent area without reducing death or thrombosis; challenges MSA as a reliable surrogate for clinical benefit in calcified PCI.

Key Points

To assess the comparative efficacy and safety of different calcium-modification strategies in patients undergoing percutaneous coronary intervention for calcified coronary lesions.
Systematic search and random-effects network meta-analysis of 22 randomized controlled trials including 4,855 patients undergoing percutaneous coronary intervention.
Evaluated the primary outcome of minimal stent area and secondary clinical outcomes including all-cause death and stent thrombosis.
Compared with noncompliant balloons, minimal stent area was significantly increased by cutting/scoring balloons (MD: 0.81 mm², 95% CI [0.36, 1.27], p=0.001), super high-pressure balloons (MD: 0.95 mm² [0.18, 1.72], p=0.016), intravascular lithotripsy (MD: 0.87 mm² [0.40, 1.34], p<0.001), rotational atherectomy (MD: 0.90 mm² [0.30, 1.50], p=0.003), and rotational atherectomy plus cutting balloon (MD: 1.24 mm² [0.46, 2.02], p=0.002).
Network ranking identified rotational atherectomy, super high-pressure balloons, and intravascular lithotripsy as the top options for expanding stent area, though no significant differences emerged across strategies for all-cause death or stent thrombosis.

p-value: p=0.001

Advanced calcium-modification strategies such as rotational atherectomy and intravascular lithotripsy improve minimal stent area compared to noncompliant balloons, but this mechanical benefit does not translate into significantly better clinical outcomes.

Simonetti et al. (2026) conducted a meta-analysis in calcified coronary lesions (n=4,855). Calcium-modification strategies (e.g., cutting/scoring balloon, intravascular lithotripsy, rotational atherectomy) vs. Standard noncompliant balloons was evaluated on minimal stent area (MSA) (MD 0.81, 95% CI 0.36-1.27, p=0.001). Compared to noncompliant balloons, calcium-modification strategies like cutting/scoring balloons increased minimal stent area (MD 0.81 mm2; 95% CI 0.36-1.27; p=0.001), but did not improve clinical outcomes.
