Background: Transcatheter aortic valve replacement (TAVR) is a minimally invasive heart procedure to
replace a thickened aortic valve that not fully opens (aortic valve stenosis). Nurses have a holistic view
point on patient care and can play a key role in the prevention of complications by using a guidelines of care
that is based upon the different educational needs of nurses and considers other relevant factors, as well as
addressing the immediate concerns of the patients and helping them cope successfully with their condition
Aim: The aim of this study is to evaluate the effect of interventional program on nurses' knowledge and
practice toward care of patients undergoing Transcatheter Aortic Valve Replacement (TAVR). Design: A
quasi experimental design. Setting: The study was conducted at cardiac catheterization units affiliated to
Ain Shams University Hospitals Cairo. Egypt. Subjects: A convenient sample of all available nurses (30) from
the previous mentioned settings willing to participate in the study. Tools of data collection: Tool (I) Nurses
self-administered structured knowledge questionnaire. It involved two parts: Part (A): Nurses' demographic
characteristics and Part (B): Transcatheter Aortic Valve Replacement knowledge questionnaire. Tool (II) Nurses'
practice observational checklist. Results: there were a statistically significant differences between mean scores
of total knowledge, practice and demographic characteristics pre and post interventional program implementation
regarding care of patients undergoing Transcatheter Aortic Valve Replacement also a positive correlation
between total knowledge, practice post program implementation have found . Conclusion: Implementation
of interventional program for nurses caring of patients undergoing Transcatheter Aortic Valve Replacement
(TAVR) had a positive effect on improving their knowledge and practical Level. Recommendations:
Availability of nursing interventional booklet regarding care of patients undergoing Transcatheter Aortic
Valve Replacement is essential in all cardiac catheterization lab as well as a Transcatheter Aortic Valve
Replacement (TAVR) care training program should be provided for nurses.
