Myocardial revascularization and ventricular restoration through pacopexy

Area of Science:

• Cardiology
• Cardiac Surgery
• Regenerative Medicine

Background:

• Ischemic cardiomyopathy often leads to significant left ventricular dysfunction.
• Restoring ventricular geometry is crucial for improving cardiac performance in these patients.

Purpose of the Study:

• To evaluate the efficacy of myocardial revascularization combined with a novel ventricular restoration technique called "pacopexy" in patients with severe ventricular dysfunction due to ischemic cardiomyopathy.
• To assess the impact of pacopexy on left ventricle performance and functional class.

Main Methods:

• Myocardial revascularization was performed in conjunction with ventricular geometric restoration using a special technique (pacopexy).
• No prostheses or synthetic materials were used in the procedure.
• Patient outcomes were assessed based on functional class, left ventricle ejection fraction, and ventricular dimensions.

Main Results:

• A significant improvement in functional class was observed in 93.10% of patients post-surgery.
• Left ventricle ejection fraction significantly increased, and left ventricle systolic diameter decreased.
• No significant changes were noted in left ventricle diastolic diameter or systolic volume.
• Follow-up ranged from 1 month to 3 years and 4 months.

Conclusions:

• The pacopexy technique for ventricular dysfunction restoration is effective in managing severe ischemic cardiomyopathy.
• The procedure demonstrated a major positive impact on the functional class of the studied patients.
• Pacopexy offers a promising, material-free approach to ventricular restoration.
