Why the study?
Does homograft replacement of aortic, mitral, or both valves improve radiographic heart size in patients requiring valve replacement?
Does homograft replacement of aortic, mitral, or both valves improve radiographic heart size in patients requiring valve replacement?
The study evaluates radiographic changes in heart size following single or double homograft valve replacement.
Answers are grounded in this paper and cite their sources.
Offers no guidance on heart size changes after homograft valve replacement; leaves open effects on cardiac remodeling.
j-Ieart size was measured radiographically before and after single or double homograft valve replacement in 69 consecutive patients. Thirty patients had aortic valve replacement, 25 mitral, and 14 both aortic and mitral valve replacement.
