Summary
Cochlear implantation in profoundly deaf children with cardiac anomalies requires careful peri-operative management. A developed protocol ensures optimal care for these complex cases.
Area of Science:
- Otolaryngology
- Cardiology
- Pediatrics
Background:
- Cochlear implantation is a safe procedure for profound deafness.
- Cardiac anomalies can complicate cochlear implantation, ranging from minor issues to life-threatening events.
- Effective peri-operative management by a cardiologist is crucial.
Purpose of the Study:
- To analyze cardiac co-morbidities in cochlear implantees.
- To develop a profile of cardiac complications impacting cochlear implantation.
- To propose a management protocol for cardiac issues related to cochlear implantation.
Main Methods:
- Retrospective case series of 30 profoundly deaf children (<12 years) with cardiac problems undergoing cochlear implantation.
- Cardiac diseases categorized into isolated Patent Ductus Arteriosus (PDA), syndromes with PDA, and syndromes without PDA.
- Incidence of cardiac disease in 30 out of 500 implantees (16.6%) identified.
Main Results:
- Identified the overall incidence of cardiac problems in profoundly deaf candidates.
- Created a descriptive profile of these cardiac issues.
- Described appropriate management strategies for identified cardiac problems.
Conclusions:
- A management protocol for cardiac co-morbidities influencing cochlear implantation has been designed.
- Provided detailed insights for optimal management from a cardiologist's perspective.
- Emphasized the importance of integrated care for these patients.
