Outcomes of Aortomitral Continuity Reconstruction During Concomitant Aortic and Mitral Valve Replacement
Main finding · Long-term survivalResult — go to the resultHR for death 1.29 95% CI 0.65–2.59Authors' conclusion
Although short-term postoperative morbidity and mortality were found to be higher for patients undergoing the Commando procedure, AMC reconstruction may be equally durable in the long term.
Study context
- Population
- Patients undergoing double aortic and mitral valve replacement, single institution, 2010–2022
- Participants
- 331 patients
- Exposure
- Commando procedure vs mitral valve replacement (MVR) + aortic valve replacement (AVR) without aortomitral continuity (AMC) reconstruction
- Commandon = 21
- Outcome
- Long-term survival
Methodological detailssingle institution, consecutive cardiac surgeries
- Single institution
- Consecutive cardiac surgeries
Main finding
As reported in the abstract
HR for death
1.29
95% CI 0.65–2.59
P = 0.496
Commando vs MVR + AVR
HR for death 1.29 (95% CI 0.65–2.59); P = 0.496
- No difference in long-term survival between groups (Kaplan-Meier, log-rank)
- P = 0.386
Observational data: associations, not effects.
Further findings
Operative mortality
- Higher in Commando: 28.6% v 10.7%
- P = 0.014
CPB time
- Longer in Commando: 312 ± 118 v 218 ± 85 minutes
- P < 0.001
Prolonged ventilation
- More in Commando: 61.9% v 31.9%
- P = 0.005
Ischemic time
- Longer in Commando: 252 ± 90 v 176 ± 66 minutes
- P < 0.001
