Hypothesis
The study aims to report the surgical explantation of a Lotus Edge valve due to prosthetic valve endocarditis and aortic annular abscess.
Conclusion
The Lotus Edge valve is difficult to remove due to its fixation after deployment, but using cold water may help facilitate its removal.
Supporting Evidence
- The patient had a history of severe aortic stenosis and underwent TAVR with a Lotus Edge valve.
- Blood cultures were positive for Streptococcus dysgalactiae subspecies equisimilis.
- Postoperative echocardiography confirmed favorable prosthetic valve function.
Takeaway
Doctors had to take out a special heart valve from an older man because it got infected, and they found that using cold water helped make the job easier.
Methodology
The surgery involved median sternotomy, cardiopulmonary bypass, and cold-saline irrigation to facilitate valve removal.
Limitations
The case report is based on a single patient, limiting generalizability.
Participant Demographics
An 85-year-old male patient.
