China approves fully bioabsorbable obturator for heart defects

Beijing, March 16 (IANS): According to Fuwai Hospital of the Chinese Academy of Medical Sciences, China’s National Medical Products Administration has issued marketing approval for a self-developed fully bioabsorbable obturator for ventricular septal defects.

Ventricular septal malformations are a common form of congenital heart disease and can cause pulmonary arterial hypertension and be life-threatening, Xinhua News Agency reported.

The new obturator developed by Chinese doctors is made from biodegradable materials. It is gradually replaced by the body’s own tissues and breaks down over time, serving as a temporary “bridge” for the heart to repair itself, according to Fuwai Hospital, also the National Center for Cardiovascular Disease.

Interventional closure is a commonly used method for treating ventricular septal defects, and it has the advantages of less trauma and a quick recovery period, whereas traditional metal obturators are designed to stay permanently in the body. , which is likely to lead to long-term complications. , said Pan Xiangbin, director of the structural heart disease center at Fuwai Hospital.

Ultrasound-guided interventional technology developed at Fuwai Hospital can replace radiation-guided technology, as it is able to detect fully bioabsorbable non-metallic materials implanted in the human body, thereby removing a major barrier to the development of such obturators. , said Hu Shengshou. , head of the hospital.
