Preoperative planning for transaortic septal myectomy using cardiac computed tomography in patients with subaortic septal hypertrophy associated with aortic stenosis: case series.

ABSTRACT:

Background

Electrocardiogram-gated cardiac computed tomography (CT) imaging enables a more accurate understanding of the patient's cardiac anatomy. Preoperative planning for transaortic septal myectomy (TASM), based on cardiac CT, may be useful in patients with subaortic septal hypertrophy associated with severe aortic stenosis (AS).

Case summary

Two elderly patients (age >80 years) with subaortic septal hypertrophy associated with AS underwent surgical aortic valve replacement (SAVR) and concomitant TASM after preoperative planning based on cardiac CT. Both patients showed subaortic septal hypertrophy with blood flow acceleration, left ventricular (LV) hypercontractility, and a short distance from the coaptation point of the mitral valve to the septum, resulting in possible
