The apex of the left ventricle is directly under the ultrasound transducer. All four chambers can be visualized. There is normal global and regional biventricular systolic function, normal excursion and coaptation of the mitral and tricuspid valves, and normal chamber sizes.

The right ventricle is under the transducer. There is normal excursion and coaptation of the aortic and mitral valves. The chambers are normal in size. There is brisk excursion of the aortic root, brisk opening of the mitral valve, a normal descent of the base of the MV, and normal thickening of the left ventricular segments.

Subcostal four chamber in a patient with pericardial effusion and tamponade. The effusion is seen as a large echolucent space around the heart. The right atrium appears collapsed in ventricular systole and the right ventricle appears compressed in ventricular diastole. These findings are both consistent with tamponade physiology.

The RVOT, LA, and LV are all dilated and appear proportionally large compared to the aortic annulus and root. Compare the relative sizes with Video 1 (normal PLAX.) There is evidence of decreased LV systolic function, with decreased motion of the aortic root, decreased excursion of the anterior mitral leaflet, decreased mitral annular excursion, and decreased thickening of the left ventricular segments. There is also a left pleural effusion.

A ME long axis view and a ME four chamber view are selected and analyzed using the Cardiac Motion Quantification (CMQ) analysis software package. First the aortic valve closure is identified and aortic valve closure time set. The ME four chamber is then selected and the LV long axis strain model is applied to the RV to allow correct labeling of septal segments. Tracking is qualitatively assessed and manually adjusted to capture the myocardium. The RV is divided into seven segments and the global strain is measured at – 29.8% with regional peak variability with all segments within limits of normal. RV Septum is de-selected to obtain RV free wall strain that is measured at -31.4%.

At the top of the image is the liver. The right atrium and right ventricle are seen well, as is the left ventricle. There is normal global biventricular systolic function. It is important to remember that, while this view often shows all four cardiac chambers, the cross section is not exactly the same as the apical four chamber.

The aortic valve is heavily calcified and does not open well. The degree of stenosis cannot be quantified from this view, but with excursion this limited the assumption should be that the patient has severe stenosis until it is proven otherwise. In addition to aortic valve calcification, the mitral annulus is heavily calcified, there is left ventricular hypertrophy, and the left atrium is enlarged.

A ME long axis view and a ME four chamber view are selected and analyzed using the Velocity Vector Imaging (VVI) software package. First the aortic valve and mitral valve closures are identified using anatomical M Mode on a static 2D image. The ME four chamber is then selected, the RV strain model is applied and the endocardium traced excluding trabeculations and the moderator band. Tracking is qualitatively assessed. Parametric display provides measurements for each of the six RV, global strain and quantification of RV apical rocking. The latter is a measurement of apical myocardial transverse motion and it is increased with dyssynchrony. Peak global strain is normal and measures -29.5%. Regional peak variability can be appreciated with the mid septal segment being the only one below normal limits. The septum de-selected to obtain global RV free wall strain that is negative 36.

First part: The ME view, obtained by slightly withdrawing the probe from the modified ME 5-chamber view in video clip 1, demonstrates two cardiac masses (“proximal” and “distal”), with the RCA penetrating the left side of the distal mass. Second part: Color flow Doppler reveals laminar blood flow in the RCA. Third part: Simultaneous orthogonal planes to the RCA based on the ME aortic valve short axis view. Fourth part: Simultaneous orthogonal planes to the tricuspid valve based on the modified trans-gastric RV inflow-outflow view.

Multiple beats are shown in this clip and the image does not remain still because the patient was severely dyspneic. The patient has significant hypertrophy of the anterioseptal wall of the left ventricle. In multiple cardiac cycles the anterior mitral leaflet can be seen to impinge on the left ventricular outflow tract.
