In addition, statistically significant improvements in pregnancy results among the study group post applying the teaching program compared to the control group (p<0.001).

Conclusion: The implementation of teaching program for pregnant women with cardiac disease was effective and showed significant improvements in the overall pregnant women's knowledge and practice about cardiac disease.

Recommendation: Continue the educational program and Special Standardized Booklet provided for pregnant women about cardiac disease and its management to decrease maternal as well as neonatal mortality and morbidity
