Key result
Intra-operative 3DTEE measurement of resected septal volume correlated well with direct measurement of the resected muscle volume (r = 0.9, P < 0.000).
Why the study?
Does intra-operative 3DTEE accurately measure the volume of resected septum compared to direct measurement in patients with HCM undergoing myectomy?

Intra-operative 3DTEE accurately estimates the volume of resected septal tissue during myectomy in HCM patients, potentially guiding surgeons to perform adequate resection and minimize complications.
May inform resection adequacy during HCM myectomy; hypothesis-generating from Level 5 evidence and requires prospective validation.
Hypertrophic cardiomyopathy (HCM) is the most common genetically transmitted cardiomyopathy. In patients resistant to medical management, myectomy is the surgical procedure of choice to reduce the symptoms of left ventricular outflow obstruction. Two-dimensional transesophageal echocardiography (2DTEE) has become part of the operative procedure by decreasing the incidence of postoperative complications. However, because of the three-dimensional geometry of left ventricular outflow tract, it is unable to comprehensively assess the location and severity of the obstruction and to provide accurate guidance during myectomy. In this study, 10 patients with HCM underwent live/real time three-dimensional transesophageal echocardiography (3DTEE) intra-operatively to measure the volume of the resected septum. This volume correlated well with the volume of the resected septal muscle directly obtained using a graduating cylinder containing water (r = 0.9, P < 0.000). 3DTEE may be potentially used as an adjunct to guide the surgeon in performing an adequate myectomy with a lower incidence of residual obstruction and complications such as an iatrogenic ventricular septal defect.

Sadat et al. (2013) conducted an observational in Hypertrophic cardiomyopathy (n=10). Live/real time three-dimensional transesophageal echocardiography (3DTEE) vs. Direct measurement using a graduating cylinder containing water was evaluated on Correlation between 3DTEE measured volume of resected septum and directly measured volume (r = 0.9, p=< 0.000). Intra-operative 3DTEE measurement of resected septal volume correlated well with direct measurement of the resected muscle volume (r = 0.9, P < 0.000).
