Background: Cardiac catheter ablation has emerged as a promising therapeutic approach for both conduction disorders and cardiac arrhythmias. As patients undergo this procedure, nurses play a pivotal role in a wide range of responsibilities and tasks. It is crucial to increase nurse practice and understanding of cardiac ablation. Aim: To assess informational needs regarding cardiac catheter ablation and to provide knowledge support to nurses regarding cardiac catheter ablation. Research design: A descriptive design was utilized in this study. Sitting: The study was conducted in the Cardiology Department at Assiut University Heart Hospital. Sample: A convenience sample of (52) nurses who are working in the cardiology department at Assiut University Heart Hospital. Tools: tool (1), interview questionnaire sheet for nurses, tool (2), Nurses' practice observation checklist sheet. Result: out of the studied nurses (73.1%) their age range between 20-30) years old, most (82.7%) of the studied nurses were female, (67.3-61.5) of studied nurses had unsatisfactory knowledge and practices regarding cardiac ablation respectively. Conclusion: The study showed that a large percentage of nursing staff members need educational and training courses regarding cardiac ablation, which contributes to improving the nursing service provided to patients. Recommendation: The study recommended that implementing well-structured in-service training programs specifically tailored to nursing recommendations for patients undergoing cardiac catheter ablation would be beneficial in enhancing nursing performance.
