SSFP cine sequences were used to acquire localisation images followed by a SSFP ventricular short axis stack to obtain coverage of the entire left ventricle (LV) and horizontal long axis (HLA), vertical long axis (VLA) and left ventricular outflow tract views (LVOT) cine in 1 cm slices.

Right ventricular diameter measurements were made on the horizontal long axis at end diastole within the basal third of the right ventricle, below the tricuspid valve, and at the level of the right ventricular papillary muscles .

Horizontal Long Axis View - University of ia

The horizontal long axis (four chamber view) is best for evaluating the septal and lateral walls and apex of the left ventricle, the right ventricular free wall, and chamber size. The mitral and tricuspid valves are also well visualized in this plane.

Normal right- and left ventricular volumes and myocardial ...

Quantification of ventricular volume by Steady State Free Precession (SSFP) cardiovascular magnetic resonance is accurate and reproducible. Normal values exist for adults, but are lacking for children. We sought to establish normal values for left and right ventricular volumes, mass and function in ...

It differs from the horizontal long axis (HLA) in that it is planned using both ventricles (see below) whereas the HLA is planned off the left ventricle only. In many patients, the 4CH and HLA are similar, but we use the 4CH because many of our patients have abnormal hearts and the HLA will not adequately image the RV and tricuspid valve.
