Transapical Beating-heart Septal Myectomy in Patient With Hypertrophic Obstructive Cardiomyopathy
December 4, 2022 updated by: Xiang Wei
Minimally Invasive Transapical Septal Myectomy in the Beating Hearts for the Treatment of Hypertrophic Obstructive Cardiomyopathy: Safety and Efficacy Results of a Phase I First-in-man Clinical Trial
The primary purpose of this study is to evaluate the feasibility, the safety and the efficacy of the transapical beating-heart septal myectomy for the treatment of hypertrophic obstructive cardiomyopathy.
This is a prospective, single-arm, single-center, first-in-man study.

Detailed Description
Surgical septal myectomy remains the gold standard for the treatment of hypertrophic obstructive cardiomyopathy.
However, conventional septal myectomy is hindered by the demanding expertise that is needed to sufficient relieve the obstruction of the left ventricle outflow tract while guarantee safety.
To increase the visualization and minimize the surgical injury of conventional septal myectomy, we have invented a novel beating-heart myectomy device.
Through a mini-thoractomy, septal myectomy could be accomplished via a transapical access in the beating heart using the beating-heart myectomy device.
The whole process of resection is monitored, navigated, and evaluated by real-time transesophageal and transthoracic echocardiography.
Left ventricle outflow tract gradient and the grade of mitral regurgitation are evaluated each time after resection.
Multiple resections are performed to tailor sufficient relief of left ventricle outflow tract obstruction and mitral regurgitation, while preventing iatrogenic injuries.
After transapical beating-heart septal myectomy, patients is scheduled to be seen for follow-up visits at discharge (about 7 days post operation) and 3 months.

Experimental: Hypertrophic Obstructive Cardiomyopathy
Transapical beating-heart septal myectomy for the patient with hypertrophic obstructive cardiomyopathy.
|
We have invented a beating-heart myectomy device.Through a minimally invasive intercostal incision, septal myectomy could be accomplished via a transapical access in the beating heart using the device.
The whole process of resection is monitored, navigated, and evaluated by real-time transesophageal and transthoracic echocardiography.
Left ventricle outlet tract gradient and the grade of mitral regurgitation are evaluated each time after resection.
Multiple resections are performed to tailor the muscular resection for sufficient relief of left ventricle outlet tract obstruction and mitral regurgitation, while preventing iatrogenic injuries.
