Initial experience with the disarticulated (one-half) Palmaz-Schatz stent: a technical report

Area of Science:

• Interventional Cardiology
• Vascular Surgery
• Biomedical Engineering

Background:

• Standard Palmaz-Schatz stent placement is challenging in complex coronary anatomies.
• Limited treatment options exist for intricate lesion locations.
• Need for adaptable stenting solutions in interventional cardiology.

Purpose of the Study:

• To present an alternative stenting method for complex coronary lesions.
• To evaluate the feasibility and safety of using disarticulated (half) Palmaz-Schatz stents.
• To demonstrate the application of this technique in various coronary anatomies.

Main Methods:

• Development of a technique utilizing one-half Palmaz-Schatz stents.
• Application of the technique in eight patients with complex coronary lesions.
• Stenting performed in the left anterior descending artery, right coronary artery, vein graft, and protected left main coronary artery.

Main Results:

• Successful deployment of half Palmaz-Schatz stents in all eight patients.
• No complications reported during the deployment of disarticulated stents.
• The technique was applied in conjunction with full stents, with varying numbers of half stents used per patient.

Conclusions:

• The use of disarticulated (half) Palmaz-Schatz stents is a feasible alternative for complex coronary lesions.
• This method offers a viable solution for anatomies previously considered too complex for standard stenting.
• Further research may explore the long-term outcomes and broader applicability of this technique.
