Insights
Complex percutaneous coronary intervention (PCI) effectively treated multi-vessel coronary artery stenosis in 56 patients, achieving a 96.4% success rate. Long-term efficacy remained high at 90.7% with a low complication rate.
Area of Science:
- Interventional Cardiology
- Vascular Medicine
- Cardiovascular Interventions
Context:
- Complex percutaneous coronary intervention (PCI) is a key treatment for patients with multi-vessel coronary artery disease.
- Evaluating the long-term outcomes and safety of complex PCI is crucial for clinical decision-making.
Purpose:
- To assess the success rate, complication profile, restenosis rates, and long-term efficacy of complex PCI in patients with multi-vessel coronary artery stenosis.
Summary:
- Complex PCI demonstrated a high success rate (96.4%) in 56 patients with multi-vessel coronary artery disease.
- Complications were low (3.6%), with restenosis in 9.4% of patients and progression of stenosis in 11.3%.
- Late efficacy, assessed at a mean of 19 months, was high at 90.7%, indicating sustained benefits.
Impact:
- Complex PCI offers a safe and effective treatment option for multi-vessel coronary artery disease, with durable long-term results.
- Understanding restenosis and progression patterns can guide post-PCI management and patient follow-up.
- The study supports the role of complex PCI in improving long-term cardiovascular outcomes.
Abstract:
56 patients with more than one stenotic coronary artery were treated by complex PTCA with success rate of 96.4%. Complications occurred in 3.6% of pts. Restenoses were found in 9.4% of pts; only one of the dilated arteries were restenosed. 11.3% of pts had repeated PTCA, because of progression of stenosis in other than previously treated artery. Angina occurred earlier in pts with restenoses than in pts with progression of stenoses. Late efficacy (mean 19 months) of complex PTCA was high (90.7%).
