2020年12月5日 · When it occurs at the upper heart chambers the condition is called Arterial Septal Defect (ASD) however when it arises between the main pumping chamber, is called a ventricular Septal Defect (VSD). Both PFO and VSD are congenital heart disorders in infants but in rare cases, it is not detected until childhood.

2023年2月8日 · 动脉导管未闭 (pda) 是主动脉和肺动脉之间的异常交通，允许含氧（红色）血液进入肺部。如果流经 pda 的血量足以引起问题，则可能需要进行干预。这最常发生在大型或中型 pda 的设置中。

The American Heart Association explains the congenital heart defect patent ductus arteriosus, PDA, in children and adults.

2023年9月26日 · Generally an ASD hole is larger than a PFO. The larger the hole, the more likely symptoms are. PFOs, on the other hand, are normal before birth but may fail to close after birth. The foramen ovale is a hole in the wall between the left and right atria of every human fetus.

Defects that involve the wall or vessels of the heart include atrial septal defect (ASD), ventricular septal defect (VSD), and patent ductus arteriosus (PDA). In certain situations, guidelines recommend surgery or transcatheter device closure to repair the defect and prevent complications.1.

2016年3月14日 · Upper row: first-pass MR angiograms in a patient with patent foramen ovale (PFO). Short axis series during the Valsalva at atrial level show a small puff of contrast (arrow) from right to left at the level of PFO on the third image which disappeared on image 4.

3、 pda ：动脉导管未闭. 动脉导管原本系胎儿时期肺动脉与主动脉间的正常血流通道，由于此时肺呼吸功能障碍，来自右心室的肺动脉血经导管进入降主动脉，而左心室的血液则进入升主动脉，故动脉导管为胚胎时期特殊循环方式所必需。

目前，能够同期进行介入治疗的先天性心脏复合畸形包括： 室间隔缺损 （ventricular septal defect，VSD）合并房间隔缺损（atrial septal defect，ASD）、VSD合并动脉导管未闭 （patent ductus arteriosus，PDA）、VSD 合并 肺 动 脉 瓣 狭 窄 （PS）、ASD 合 并PDA、ASD合并肺动 …

2024年4月8日 · 介入封堵手术已成为房间隔缺损（asd）、动脉导管未闭（pda）及卵圆孔未闭（pfo）等先天性心脏病的首选治疗方法。 研制具有良好生物相容性的完全可降解封堵器，使其作为引导自体组织生长填补缺损的“桥梁”，实现“介入无植入”，是未来的发展趋势，且这 ...

ASD: atrial septal defect; PDA: patent ductus arteriosus; TGA: transposition of the great arteries; VSD: ventricular septal defect. There are a few signs that should alert generalists to the possibility of congenital heart disease: right bundle branch block (RBBB) – this occurs in 1% of the middle-aged population without disease.
