Short- and Mid-Term Prognosis of Patients Undergoing Rotational Atherectomy in Aortoostial Coronary Lesions in Left Main or Right Coronary Arteries

Résumé

Objective: To determine short-term and mid-term prognosis in patients with calcified ostial coronary lesions who underwent rotational atherectomy (RA). Background: RA was developed to facilitate stenting in complex lesions. Treatment of calcified aortoostial coronary lesions with RA appears to have poorer procedure outcomes than nonostial lesions; yet the literature on this topic is scarce. Methods: Of 498 consecutive patients who underwent RA, a total of 80 (16.1%) presented with aortoostial lesions. A comparative, monocentric study was performed between patients with aortoostial and nonaortoostial stenosis, in a retrospective registry. The primary endpoint was the procedural success rate. Secondary endpoints were the rates of major adverse cardiac and cardiovascular events (MACE) at 30 days and 24 months. Results: The procedural success rate was high and similar in patients with and without ostial lesions (96.3% vs 94.7%, p=0.78), as was the rate of angiographic complications (7.5% vs 8.4%, p=0.80). However, the 30-day mortality rate was significantly higher in the aortoostial group (11.3% vs 4.8%, p=0.04), as was the 24-month rate of MACE (43.8% vs 31.8%, p=0.04). The aortoostial location of the lesion was an independent factor associated with the occurrence of cardiovascular events at 24 months (HR = 1.52, 95% CI, 1.03-2.26, p=0.035). Conclusion: Procedural success and complication rates were similar in patients with and without aortoostial lesions. Despite a poor short- and mid-term prognosis, rotational atherectomy appears to be a feasible and safe treatment option for calcified aortoostial coronary lesions.
