Insights
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.
Introduction:
Cochlear implantation is a safe surgery for restoration of hearing in profoundly deaf candidates. Profound deafness may at times, manifest as a part of a syndrome associated with cardiac anomalies. Cardiac co-morbidities may influence cochlear implantation in a spectrum of ways from minor intra operative issues to major life threatening complications. Issues related to pre operative, intra operative and post operative care needs to be addressed by an efficient in house cardiologist.
Objectives:
Our retrospective study was aimed at analyzing the various cardiac co-morbidities encountered in 30 out of 500 cochlear implantees over a period of 14 years (July 1999-June 2012). This study was focused on developing a profile of cardiac complications influencing cochlear implantation and suggests a protocol for management of various cardiac issues related to cochlear implantation. Our article also reflects the cardiologist's perspective of peri-operative care to be given during cochlear implantation. Relevant literature has been reviewed.
Methods:
Case series of 30 profoundly deaf children (below 12 years) who had associated cardiac problems and underwent cochlear implantation in our institution were included in our study. Overall cardiac disease was identified in 30 out of 500 implantees (16.6%) in our experience. The cardiac disease can be categorized into 3 groups: candidates with isolated Patent Ductus Arteriosus (PDA) as Group A (8/30), candidates with syndrome and other anomalies with PDA association as Group B (18/30), and candidates with syndromes without PDA association as Group C (4/30).
Results:
The overall incidence of cardiac problems in profoundly deaf candidates is identified. Descriptive profile of the same has been created and appropriate management for the same described.
Conclusions:
A protocol for management of cardiac co-morbidities influencing cochlear implantation has been designed and detailed insight for the optimal management of these issues has been discussed with cardiologist's perspective.
