Background

Percutaneous coronary intervention (PCI) using a drug-coated balloon (DCB)-only strategy remains investigational for the treatment of calcified coronary lesions.

Methods

This retrospective, descriptive, single-arm study included patients with calcified coronary lesions who underwent DCB-only PCI between January 2023 and May 2024 at a single center. Calcification was identified by angiography or intravascular imaging. Patients who received hybrid treatment defined as the combination of a DCB and a drug-eluting stent (DES) or were lost to follow-up were excluded. Baseline characteristics, procedural details, and clinical outcomes, including cardiovascular death, target vessel myocardial infarction (TVMI), and clinically driven target lesion revascularization (CD-TLR), were collected at 30 days and 1 year.

Results

A total of 52 patients underwent DCB-only PCI for calcified coronary lesions. After excluding three patients lost to follow-up, 49 were analyzed. Most were male (73.5%) with a median left ventricular ejection fraction of 56%. The clinical indications were chronic coronary syndrome (61.3%), and acute coronary syndrome (38.7%), with the left anterior descending artery being the most frequently involved vessel (69.8%). Chronic total occlusion and bifurcation lesions were present in 38.5% and 6.1% of cases, respectively. Intravascular imaging was used in 30.6% of patients. Calcium length > 10 mm was observed in 63.3% of lesions. No patients underwent rotational atherectomy, orbital atherectomy, or intravascular lithotripsy. All lesions were prepared using modified balloons, predominantly cutting (59.2%) and scoring (40.8%). The median DCB size and total length were 3.0 mm (range 2.5-4.0 mm) and 35 mm (range 15-90 mm). Most DCBs were paclitaxel-based (75.5%). At 30-day follow-up, one cardiovascular death (1.9%) occurred. No TVMI or CD-TLR was observed. No further events occurred at 1 year.

Conclusion

DCB-only PCI for calcified coronary lesions was associated with low observed rates of adverse clinical events at both 30-day and 1-year follow-up in this single-center cohort. These findings may help guide the design of future prospective studies.
