My sister bitterly regretted having to abort ectopic twins but she was more traumatised by the death of her son who lived a full day after being delivered to term with only half a heart.

Not only because she bonded with the boy during his very short and distressed life but also because she was sterilised as it was her third necessary caesarian section.

If the defect could have been detected early the pregnancy could have been aborted and she could have had a son with a viable chance of life. Instead of a day of life suffering.
