To clarify clinically the pathogenesis of septal hypertrophy in terms of its morphology and wall dynamics, simultaneous biventricular cineangiography (BVG) and endomyocardial biopsy of the left ventricle were performed for patients with left ventricular hypertrophy. The patients were categorized in four groups according to their clinical and BVG findings; 1) 24 normal control subjects (C), 2) 39 patients with hypertension and symmetrical septal hypertrophy (SH-HT), 3) 17 patients with hypertension and asymmetrical septal hypertrophy characterized by the ratio (IVS/PW) greater than or equal to 1.3 by BVG, and 4) 25 patients with hypertrophic cardiomyopathy (HCM). The BVG's configuration of the septum in SH-HT showed a normal form of septal hypertrophy (NH form) essentially similar to that of the control subjects (N form), except for septal thickness increases of more than 10 mm. In HCM, a triangle or shell (TS) form or spindle (S) form of the septum was demonstrated by BVG. The TS form was characterized by straight or convex thickening of the septum from its center to its base toward the left ventricle. The S form was characterized by convex thickening localized to the central part and a relatively thin base. However, the configuration in ASH-HT was either the NH form (7 cases) or the TS or S form (10 cases). The configuration in ASH-HT with the NH form was not distinguishable from that of SH-HT, nor was the configuration in ASH-HT with the TS or S form distinguishable from that of HCM. Systolic thickening (%) of the septum and systolic shortening (%) of the septal length decreased significantly in this order: C, SH-HT, ASH-HT with the NH form, and ASH-HT with the TS or S form. Those of HCM were similar to those of ASH-HT with the TS or S form. In the cases of the N or NH form, there was a negative correlation between systolic thickening (%) and thickness of the septum in diastole. In cases with the TS or S form, systolic thickening (%) was not affected by the thickness of the septum in diastole, and a lower value was observed in all cases. Histological studies of endomyocardial biopsies revealed a positive correlation between the transverse diameters of the myocytes and the total systemic peripheral resistance (TSPR) in 25 patients with SH-HT. In 12 patients with HCM, there was no correlation, and severe hypertrophy of the myocytes was observed despite a lower TSPR.(ABSTRACT TRUNCATED AT 400 WORDS)
