Why the study?

Does the degree of coronary calcification and the use of adjunctive rotational atherectomy affect acute lumen gain and stent expansion in patients undergoing coronary stenting?

Implication

Calcified lesions may limit acute stent expansion; supports hypothesis-generating use of rotational atherectomy but requires randomized confirmation.

Structured PICO

Does the degree of coronary calcification and the use of adjunctive rotational atherectomy affect acute lumen gain and stent expansion in patients undergoing coronary stenting?

Population

303 patients (197 men, mean age 63.9 +/- 11.5 years) with 323 native coronary artery lesions treated with Palmaz-Schatz stents, differentiated by degree of circumferential calcification.

Intervention

Palmaz-Schatz stent implantation, with adjunctive rotational atherectomy used prior to stent placement in 117 lesions.

Comparator

Comparison across different degrees of calcification (0-90, 91-180, 181-270, and 271-360 degrees) and pre-treatment with balloon angioplasty.

Outcome

Minimal and maximal lumen diameter, lumen cross-sectional area, acute lumen gain, and eccentricity index measured by intravascular ultrasound and quantitative angiography after stent placement.surrogate

Increasing coronary calcification impairs optimal stent expansion, but adjunctive rotational atherectomy prior to stenting improves acute procedural lumen gain.
