D-Shaped Left Ventricle, Anatomic, and Physiologic Implications
Figure 3
Relation of morphology of right and left ventricle.
(a) Normal; the left ventricle (LV) is spherical and larger than the right ventricle (RV) |
(b) Severe right ventricular hypertrophy; the RV now becomes more spherical and pushes the septum into the LV, thus restricting left ventricular diastolic filling (D-shaped left ventricle) |
(c) Pictorial representation of D-shaped left ventricle improvement after volume removal; the LV starts expanding and slowly returns to normal shape and size due to reduced RV preload |
