Left ventricular reconstruction with no-patch technique: early and late clinical outcomes

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery Outcomes
• Left Ventricular Reconstruction

Background:

• Limited data exists on the late clinical outcomes of the no-patch technique for large left ventricular aneurysms.
• Assessing the efficacy of this technique is crucial for surgical decision-making.

Purpose of the Study:

• To evaluate the no-patch surgical technique for left ventricular reconstruction in patients with left ventricular aneurysms.
• To assess the early and late clinical outcomes associated with this technique.

Main Methods:

• A cohort of 145 patients with dyskinetic left ventricular aneurysms underwent reconstruction using the no-patch technique starting in 1995.
• Follow-up averaged 59 months (range 1-127 months).
• Statistical analyses included bivariate analysis for early mortality risk factors, Cox proportional hazards model for all-cause mortality and readmission, and Kaplan-Meier for survival.

Main Results:

• Left ventricular end-diastolic diameter decreased post-operation, restoring a more normal conical shape.
• Early mortality was 3%, with a late mortality of 11%.
• Five-year hospital readmission was 28%; 1-, 5-, and 10-year survival estimates were 95%, 86%, and 74%, respectively. Readmission-free survival at 1 and 5 years was 87% and 60%.

Conclusions:

• The no-patch technique is a simple and effective procedure for left ventricular reconstruction.
• This technique yields satisfactory early and late clinical outcomes in patients suffering from left ventricular aneurysms.
