Summary
Systolic anterior motion of the mitral valve occurred after a David procedure. This complication, previously seen after other heart surgeries, is now reported after isolated ascending aortic surgery.
Area of Science:
- Cardiovascular Surgery
- Cardiac Mechanics
- Mitral Valve Dynamics
Background:
- The David procedure is an aortic valve-sparing root replacement technique.
- Systolic anterior motion (SAM) of the mitral valve is a known complication after certain cardiac surgeries.
- Previous reports of SAM have been associated with mitral valve repair/replacement and aortic valve replacement.
Observation:
- A case of hemodynamically significant systolic anterior motion of the mitral valve was observed.
- This event occurred in the context of a patient who underwent a David procedure.
- The SAM significantly impacted the patient's cardiac hemodynamics.
Findings:
- This is the first reported instance of systolic anterior motion following an isolated ascending aortic surgery (David procedure).
- The findings highlight a potential, previously undescribed complication of this specific aortic surgery.
- Hemodynamic significance of the observed SAM necessitates clinical attention.
Implications:
- Clinicians should be aware of the potential for SAM after David procedures.
- This case expands the understanding of complications associated with aortic valve-sparing root replacement.
- Further investigation may be warranted to elucidate the mechanisms and incidence of SAM post-David procedure.

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
