After ischema and hypertension, what are two other relatively common causes of cardiomyopathy?
An infective myopathy and alcohol (beriberi).
There is massive cardiomegaly with extreme dilatation of the right and left atria. Prosthetic mitral and tricuspid valves. Single lead pacemaker with tip in the right ventricle. There is marked dilatation of the pulmonary veins. Pulmonary arteries are enlarged. No thoracic lymphadenopathy.
There is left lower lobe consolidation and subtle bilateral perihilar ground glass attenuation with increased interstitial markings in the bases. Tiny left pleural effusion.
Conclusion: There is lower lobe consolidation, likely infective. Perihilar ground glass change suggests a degree of fluid overload. Background massive cardiomegaly with a pattern in keeping with a multi-valvular (tricuspid and mitral) disease.
