i am so sad for your husbands condition.
the pain may occur due to aortic stenosis
itself or it may be associated with ischemic heart disease
aortic valve replacement
is needed in symptomatic case.
before operation it is mandatory to do angiogram to exclude coronary artery disease.
now, the question about the pulmonary valve replacement
why it is needed?
is there associated valvular problem?
all inv. report is needed to check before giving a comment.
