Two-Dimensional Echocardiograms

Right parasternal long-axis view of four chambers

Note that the right ventricular free wall is 6 mm (0.6 cm) thick whereas the left ventricular free wall is 4 mm thick. RV - right ventricular cavity; LV - left ventricular cavity; RA - right atrial cavity; LA - left atrial cavity.

Right parasternal long-axis view of four chambers and aorta

RV - right ventricular cavity; LV - left ventricular cavity; Ao - aorta; LA - left atrial cavity.

Right parasternal cranial long-axis view of ventricles and aorta

RV - right ventricular cavity; LV - left ventricular cavity; Ao - aorta

Left apical four-chamber view

The arrow points to one of the primary abnormalities that makes up this cat's congenital heart disease. RV - right ventricular cavity; LV - left ventricular cavity; RA - right atrial cavity; LA - left atrial cavity

Right parasternal cranial short-axis basilar view

The arrow again points to the the same abnormality seen in the echocardiogram immediately above this one. Although it looks like the abnormality is between the aorta and right ventricle, it is high on the septum. RV - right ventricular cavity; A0 - aorta; LA - left atrial cavity

Right parasternal view of the right ventricle and main pulmonary artery

This view shows a markedly malpositioned pulmonic valve. The valve is difficult to visualize but sits between the right ventricle (RV) and main pulmonary artery (MPA) at about 2 o'clock, instead of the normal 3 to 4 o'clock position.
