Prosthetic valve sparing aortic root replacement shows favorable short- and midterm outcomes, suggesting it is a viable option. Careful primary surgery is crucial, especially in patients with aortopathy, to prevent future interventions.
Area of Science:
- Cardiovascular Surgery
- Aortic Surgery
- Prosthetic Valve Surgery
Background:
- Limited data exists on outcomes of prosthetic valve sparing aortic root replacement (PVSRR) following prior aortic valve replacement (AVR).
- Aortopathy and tears at the aortic sinus or aortotomy site are key considerations in patients requiring repeat aortic procedures.
Purpose of the Study:
- To evaluate the short- and midterm clinical outcomes of patients undergoing PVSRR after AVR.
- To assess the safety and efficacy of PVSRR in a specific patient cohort.
Main Methods:
- A retrospective review of 21 patients who underwent PVSRR between June 2004 and March 2018.
- Analysis of patient demographics, surgical history (mean 10.62 years post-AVR), and perioperative/follow-up outcomes.
Main Results:
- One perioperative death occurred in an emergency surgery case for acute type A aortic dissection.
- Kaplan-Meier survival estimates at 1, 3, and 5 years were 95.2%, 85.7%, and 85.7%, respectively.
- 100% freedom from reoperation at 5 years, with no cardiac or aortic reinterventions needed post-PVSRR.
Conclusions:
- PVSRR demonstrates favorable short- and midterm results, indicating its validity as a surgical option.
- Meticulous primary surgery is essential, particularly in patients with aortopathy, to minimize the risk of subsequent interventions.
