Heart: hypertrophic cardiomyopathy - indirect (jugular) angiogram

= annotation - select to reveal
  1. The cardiac silhouette is enlarged - the trachea is elevated and the heart is wide (>2 rib spaces). An ''indirect'' angiogram is achieved by infusion of a bolus of contrast material into the jugular vein. In this relatively late-phase radiograph, the left side of the heart is opacified.
  2. The left atrium is dilated.
  3. The left ventricular chamber is small,
  4. and the wall is thickened.
  5. The aorta and brachiocephalic trunks are poorly opacified (arrow). This may indicate poor cardiac output. The pulmonary veins are engorged. Angiography can be helpful in the diagnosis of structural abnormalities, in the absence of echocardiography.
