Angiographic Results and Late Clinical Outcomes Utilizing a Stent Synergy (Pre-Stent Atheroablation) Approach in Complex Lesion Subsets.
To investigate the strategy of ÒdebulkingÓ in complex lesions before stent implantation (stent synergy) to improve procedural safety and achieve optimal acute and long-term results, we reviewed our experience in 389 patients with 504 lesions undergoing a combined stent procedure (45% rotational atherectomy, 24% laser angioplasty, 20% directional atherectomy, and 11% transluminal extraction atherectomy before stent implantation). Procedural success was achieved in 94.5%, with 4% major ischemic complications (1.1% death, 1.9% Q-wave myocardial infarction, and 2.3% emergency coronary artery bypass surgery). Overall, subacute stent thrombosis occurred in 1.5% of patients. Target-lesion revascularization during follow-up was required in 9.8% of the patients. We conclude that a strategy of selective pre-stent atheroablation in complex lesion subsets results in excellent procedural outcomes with acceptable complications and favorable long-term results.
