Summary
Multifocal angioplasty, involving multiple sites, is infrequent, occurring in only 1.5% of procedures. A distinct patient group with multifocal angioplasty spread over years shows better outcomes than those treated in a short period.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Multifocal atherosclerotic lesions are common, suggesting a potential for frequent multifocal angioplasties.
- This study investigates the incidence and characteristics of multifocal angioplasty procedures.
Purpose of the Study:
- To determine the frequency of multifocal angioplasty.
- To analyze patient groups and outcomes based on the timing of multifocal angioplasty procedures.
Main Methods:
- Retrospective analysis of 5344 angioplasties (coronary and peripheral) performed over 10 years.
- Identification of 80 multifocal angioplasties in 30 patients, categorized into two groups based on procedure timing.
Main Results:
- Multifocal angioplasty represented 1.5% of all procedures, involving 30 patients.
- Group I (multifocal lesions < 3 months) had higher complication (20%) and restenosis (21%) rates compared to Group II (multifocal angioplasty > 2 years) (3% and 7%, respectively).
- Group II patients were younger (mean 46 vs 52 years) and had a higher primary success rate (100% vs 90%).
Conclusions:
- Multifocal angioplasty is an infrequent procedure.
- A specific patient subgroup undergoing multifocal angioplasty over an extended period (>2 years) demonstrates superior outcomes, including lower complication and restenosis rates.
