Nettet12. aug. 2016 · Hypertrophy is detectable only in the mid portion of the left ventricle and involves the papillary muscles, resulting in a systolic obstruction of the mid-ventricle (Fig. 2D). This pattern shows smaller LV diastolic volumes and a muscular apposition of the septum and LV free wall able to produce a pressure gradient (PG) [ 11 ]. Nettettion of LV walls, and smaller left ventricular cavity size. The spectral profile of patients with AS, HOCM, and LVCO is differentiated by the peak/mean gradient ratios of 2 or less, 2–3, and 3 or greater, respectively, in >90% of patients. Most patients with LVCO without HOCM or severe LVH have an ICG < 36 mm Hg.
