Key result
Preoperative 3D computed tomography reconstruction of the left ventricular outflow tract is feasible and useful for understanding live-heart anatomy in hypertrophic obstructive cardiomyopathy.
Case Report (n=1)
Preoperative 3D computed tomography reconstruction provides valuable morphological details of the left ventricular outflow tract in hypertrophic obstructive cardiomyopathy, aiding surgical understanding.
Hypothesis-generating for LVOT assessment in HOCM; should not yet alter surgical planning.
We present optimally reconstructed three-dimensional computed tomography images of left ventricular outflow obstruction, comprehensive left ventriculography, and comparable intraoperative transesophageal echocardiography, as well as serial operative pictures, to facilitate the understanding of live-heart anatomy of hypertrophic obstructive cardiomyopathy. As shown in this case, detailed morphological analysis around the left ventricular outflow tract using preoperative computed tomography would be feasible and useful. The present case highlights the importance of obtaining complete three-dimensional information present in the acquired computed tomography dataset because computed tomography is not entirely noninvasive or free of radiation exposure and contrast material.

Toh et al. (2018) conducted a case report in Hypertrophic obstructive cardiomyopathy (n=1). Three-dimensional computed tomography reconstruction was evaluated. Preoperative 3D computed tomography reconstruction of the left ventricular outflow tract is feasible and useful for understanding live-heart anatomy in hypertrophic obstructive cardiomyopathy.
