Application of Circular Patch Plasty (Dor Procedure) or Linear Repair Techniques in the Treatment of Left Ventricular...

Area of Science:

• Cardiovascular Surgery
• Cardiac Reconstruction
• Medical Device Technology

Background:

• Left ventricular aneurysm repair is a critical procedure for post-infarction patients.
• Myocardial revascularization is often performed concurrently.
• Evaluating different surgical techniques is essential for optimizing outcomes.

Purpose of the Study:

• To compare early clinical outcomes and echocardiographic left ventricular measurements.
• To assess the efficacy of endoventricular circular patch plasty (Dor procedure) versus linear repair.
• To evaluate these techniques in conjunction with myocardial revascularization.

Main Methods:

• Retrospective analysis of 89 patients undergoing left ventricular aneurysm repair and myocardial revascularization (1996-2016).
• Patients were divided into two groups: Dor procedure (n=48) and linear repair (n=41).
• Data collected included patient demographics, disease characteristics, surgical procedures, and in-hospital mortality.

Main Results:

• Multi-vessel disease was present in 61.7% of patients.
• The Dor procedure group received an average of 2.1 grafts, while the linear repair group received 2.9 grafts.
• In-hospital mortality was 4.1% for the Dor procedure and 7.3% for the linear repair (P>0.05).

Conclusions:

• Post-infarction left ventricular aneurysm repair is feasible with both Dor and linear techniques.
• Both surgical approaches offer acceptable risk profiles.
• Satisfactory hemodynamic improvement was observed with both methods.
