Size and Shape of Right Heart Chambers in Mitral Valve Regurgitation in Small-Breed Dogs

Carlsson, Carolina; Häggström, Jens; Eriksson, A; Järvinen, AK; Kvart, Clarence; Lord, Peter

Abstract

RH chambers are not significantly dilated in dogs with mild to moderate MR without CHF. In CHF, RH chambers enlarge and also may be compressed by the LH chambers. Pulmonary hypertension probably is present in some dogs with CHF. Increased sternal contact is not a useful sign of right-sided heart dilatation in MR.
