Our study aimed to investigate the gross anatomy aspects of the fossa ovalis (FO) and the presence of some anatomical variation resulting from the incomplete fusion of septum primum and septum secundum, such as an atrial septal pouch (SP) and left atrial septal ridge. Thirty-one adult human hearts removed from formalin-fixed specimens were examined to provide information about the morphology of the FO. The organs were free of any gross anatomically visible pathological conditions. The most common variants were the FO located in the inferior part of the interatrial septum (64.51%), circular (61.3%), with a net-like structure (51.62%), prominent limbus (93.55%), and patent foramen ovale (PFO) (25.8%). The right SP was observed in 9.67% of specimens, the left SP was observed in 29.03% of cases, and in 51.61% of cases, a double SP was observed. One sample presented a right SP and a double left SP, and one case showed a triple left SP, which was not reported previously to our knowledge. Knowledge of the interatrial septal anatomy becomes important for interventional cardiologists and should be documented before transeptal puncture.
本研究旨在探讨卵圆孔（FO）的大体解剖学特征以及由于原发隔和继发隔不完全融合而导致的一些解剖变异，如房间隔憩室（SP）和左房间隔嵴。我们检查了 31 个来自福尔马林固定标本的成人心脏，以提供有关 FO 形态的信息。这些器官没有任何肉眼可见的明显病理状况。最常见的变异是 FO 位于房间隔的下部（64.51%）、圆形（61.3%）、具有网状结构（51.62%）、明显的边缘（93.55%）和开放的卵圆孔（PFO）（25.8%）。9.67%的标本观察到右侧 SP，29.03%的病例观察到左侧 SP，51.61%的病例观察到双 SP。一个样本出现右侧 SP 和左侧双 SP，一个病例显示左侧三 SP，据我们所知，这此前尚未报道过。了解房间隔的解剖结构对于介入心脏病学家很重要，在进行房间隔穿刺之前应记录下来。
