The latest issue of the Chinese Journal of Thoracic and Cardiovascular Surgery published a Chinese consensus on transthoracic minimally invasive ventricular septal defect closure written by experts led by the Cardiovascular Surgeons Branch of the Chinese Medical Association (Chinese Journal of Thoracic and Cardiovascular Surgery, Vol. 27, No. 9, September 2011, 516-518). According to the consensus, ventricular septal defect (VSD) is the most common congenital heart disease, accounting for about 20% of all congenital heart diseases. Currently, there are two main treatment methods: one is surgical repair with the assistance of extracorporeal circulation (CPB); the other is percutaneous catheter interventional sealing. In recent years, scholars at home and abroad have explored the technique of minimally invasive transthoracic occlusion of VSD by applying a modified blocker and delivery system under the guidance of esophageal ultrasound by integrating the technical features of traditional surgical techniques and cardiac catheter interventions. This technique avoids the trauma and potential complications of extracorporeal circulation surgery on the one hand, and radiological radiation and the age and weight restrictions of infant patients on the other. According to incomplete statistics, more than 5000 patients with ventricular septum have been successfully cured by this procedure in China, and our scholars have accumulated considerable experience, and the technique is rapidly being promoted and applied. Indications: (1) age usually R3 months old; (2) simple perimembranous VSD with hemodynamic abnormalities, VSD diameter 4-8 mm for those within 1 year; (3) simple myocardial VSD with hemodynamic abnormalities, 3 mm diameter and multiple myocardial VSDs; (4) sub-stem VSD without combined obvious aortic valve prolapse, VSD diameter 6 mm for those within 1 year; (5) post-surgical residual shunt; (6) myocardial infarction or post-traumatic ventricular septal perforation. Contraindications: (1) poorly aligned VSD; (2) postseptal atrioventricular access VSD; (3) combined with significant aortic valve prolapse with moderate or greater aortic regurgitation; (4) infective endocarditis with intracavitary bulges; (5) combined with other cardiovascular malformations that require simultaneous CPB surgical correction, but does not include complex malformations with combined VSDs that require the use of this technique to shorten CPB and blocking time, etc.” Our hospital was the first to perform this technique in Beijing and has successfully performed this technique in more than 10 cases, ranging in age from 6 months to 31 years old, with a minimum weight of 6 kg, which includes patients with ventricular defects in all locations and post-surgical residual shunts. The longest follow-up of this group of patients is now close to one year, with satisfactory results. The latest acquisition of the GE vivid I portable cardiac ultrasound machine and adult and pediatric esophageal probes in our cardiac center now provides clearer ultrasound images of the esophagus, providing a stronger guarantee for the success of the transthoracic minimally invasive ventricular septal defect closure technique.
