Does biventriculo-cineangiography identify distinct morphological patterns in patients with hypertensive left ventricular hypertrophy?
Hypertensive left ventricular hypertrophy presents with distinct angiographic patterns, including an asymmetrical septal hypertrophy variant that mimics hypertrophic cardiomyopathy.
In the present study, we demonstrated that hypertensive left ventricular hypertrophy can be divided angiographically into symmetrical (SH) and asymmetrical septal hypertrophy (ASH) groups. In the SH group, the dynamics of the septal wall and the free wall were almost the same as those of the control group. On the other hand, the ASH group rather resembled the HCM group in the thickness and dynamics of the septal wall and the free wall as well as in the septal configuration. The most characteristic difference of the ASH and HCM groups from the SH group was in the significantly greater thickness of the septal wall at end diastole. However, in view of the developmental mechanism of hypertensive heart, it is interesting to note that the more the septal-free wall ratio increases, the more the thickness of the septal wall increases in the SH group.
