Close to the Heart
Specialists tell me it’s not all there, my interatrial septum. Blood that should be routed to my lungs to be filtered can, instead, be passed through that barrier. Flow in one direction can cause oxygen-rich blood to join blood going to the lungs, overtaxing them. Flowing in the other direction, blood that needs to be filtered by the lungs will join blood destined for the brain, which can lead to mayhem.
More than sixty-five years of my life passed before this was discovered. By a stroke of luck, my one stroke was minor. When it passed through the hole in my heart, a tiny clot that could have come from any injury did reach my brain, but its effect was minor. The hole can be closed with surgery, but with a high risk of complications due to my age – so I accept this defect as a part of my whole.

This is my response to Haibun Monday 1/30/23: Heart
Per Wikipedia:
Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart. Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO). It is common in patients with a congenital atrial septal aneurysm (ASA) – a bulging in the septum (or barrier) between the atria, which I also have.
