Aortic valve repair (AVr) in acute type A aortic dissection (ATAAD) shows comparable mortality to aortic valve replacement (AVR). AVr also resulted in fewer complications like heart block and bleeding.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Disease Management
Background:
- Acute type A aortic dissection (ATAAD) is a critical surgical emergency.
- Aortic valve replacement (AVR) is frequently performed during ATAAD repair.
- Aortic valve repair (AVr) is an emerging alternative with promising single-center results.
Purpose of the Study:
- To investigate national trends in AVr versus AVR for ATAAD.
- To compare in-hospital outcomes between AVr and AVR in ATAAD patients.
- To evaluate the safety and efficacy of AVr in the context of ATAAD.
Main Methods:
- Analysis of the National Inpatient Sample database (2016-2017).
- Inclusion of adult patients with primary diagnosis of acute thoracic aortic dissection undergoing proximal aortic surgery.
- Stratification into isolated aortic surgery, AVR, and AVr groups; propensity score matching for AVR vs. AVr comparison.
Main Results:
- Out of 5115 patients, 15% underwent AVr and 22% underwent AVR.
- Propensity-matched analysis showed no significant difference in mortality or stroke between AVr and AVR.
- AVr was associated with significantly lower rates of heart block (1.1% vs. 7.5%) and bleeding (65.9% vs. 81.3%), and shorter length of stay.
Conclusions:
- Aortic valve repair (AVr) is a safe and viable option for selected patients with ATAAD.
- AVr offers comparable mortality and composite outcomes to AVR in ATAAD.
- Reduced rates of heart block and bleeding suggest potential advantages of AVr in ATAAD management.
