The shape of the heart is also important in cats. Remember the "valentine" description? Perhaps appropriate considering the date tomorrow!

Also the heart width shouldn't be more than 1/2 of the thoracic width on VD, and not more than 2.5 intecostal spaces on the lateral (it's tricky in cats due to more sternal contact when they are older). Also usually there should be some space between the caudal waist and the diaphragm on the lateral view. Any other methods?

the x-ray study of the thorax is suspicious of cardiac disease an ecocardiogram could complete the exam

possible differential diagnosis are (parasitic)Aelurostrongylosis, (inflammatory) Pneumonitis, at least neoplastic

Feline cardiomegaly can be hard to pick up, so I recommend comparing it to a<a href="http://mirc.veterinaryradiology.net:8080/Teaching-File/documents/20081210114804606/MIRCdocument.xml" rel="nofollow"> normal thorax</a> if you have one available. What methods and measures could you use to determine whether the heart is enlarged? There is a little bit of air in one lateral projection that disappears on the other. I usually consider this transient because of the stress of taking the radiographs. I didn't give you much history to go on, but you'd want to take that into account.

Possible cardiomegaly- the atria seem to be enlarged. But the pulmonary vasculature is within normal limits. Diffuse interstitial pattern. I would suspect megaesohagus in this cat?

Cardiomegaly. Mineralised opacities on lateral rads superimposed on the kidneys. I wonder if the right caudal pulmonary artery is enlarged on the VD view? dd: Pneumonitis/Cardiac disease with edema/Lymphoma/Metabolic disease due to uremia-in case of ranal disease/ Bronchopneumonia.
