Now, sometimes, individuals might have an atrial septal defect, a small opening between the right and left atrium.

同时，某些人患有房间隔缺损，即右房房之间有一个小缺口。

Atrial septal defect, but you feel it's an emergency?

- 房间隔缺损，但您觉得这是紧急情况？

Atrial septal defect is a defect within the upper two chambers of the heart.

- 房间隔缺损是上部两腔内缺损。

Next up, there's a multicenter randomized clinical trial about atrial septal defect, or ASD, closure.

接下来，有一项关于房间隔缺损（ASD）封堵多中随机临床试验。

In ASD patients, this septum is defective allowing blood flow between the two chambers.

ASD患者房间隔是有缺损，可以在两个房内流动。

Small ASDs do not cause any symptoms and may not require treatment.

很小房间隔缺损不会引起任何症状，不需要治疗。

Large atrial septal defects that cause clinically significant symptoms usually require surgical closure.

大型房间隔缺损会导致有临床意义症状，通常需要手术封闭。

Fortunately, this complication, called the Eisenmenger syndrome, usually develops over many years and occurs only in a small percentage of people with large atrial septal defects.

幸运是，该并发症，被称为艾森曼格综合征，通常需要很多年，而且仅在少部分有大房间隔缺损人群中出现。

The researchers found that the bioabsorbable occluder was non-inferior to the metallic occluder for ASD closure, with success rates of 96.5% and 97.4%, respectively, suggesting a possible new option for ASD closure.

研究人员发现，生物可吸收封堵器在房间隔缺损（ASD）封堵术中效果不劣于金属封堵器，成功率分别为96.5%和97.4%，提示生物可吸收封堵器可能成为ASD封堵一种新选择。
