Summary
Autologous pericardial patch plasty for aortic valve repair (AVR) offers satisfactory functional results. This technique effectively treats aortic regurgitation and addresses complex valve pathologies, promoting valve preservation.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Thoracic Surgery
Background:
- Isolated aortic valve repair (AVR) is gaining interest, with variable reported outcomes.
- Autologous pericardial patch plasty is an emerging technique for AVR.
Purpose of the Study:
- To analyze the experience with isolated AVR using autologous pericardial patch plasty.
- To compare outcomes of AVR with pericardial patch plasty versus AVR without additional material.
Main Methods:
- A retrospective analysis of 42 patients undergoing AVR with pericardial patch plasty (PATCH) and 42 age-matched controls (NO-PATCH) between 1997 and 2005.
- Echocardiographic follow-up for a cumulative 2341 patient-months (mean 28 months).
Main Results:
- No in-hospital mortality in either group.
- Similar average systolic gradients (5.9 mmHg in PATCH vs. 4.8 mmHg in NO-PATCH).
- Five-year freedom from significant aortic regurgitation was 87.8% in PATCH and 95.0% in NO-PATCH; freedom from reoperation was comparable (97.6% vs. 97.4%).
Conclusions:
- Aortic valve repair using pericardial patch plasty effectively treats aortic regurgitation with satisfactory functional results.
- This technique can address complex aortic valve pathologies, extending valve preservation strategies.
- Pericardial patch plasty represents a viable option for aortic valve repair.
