Berit Mila Decision Miraculously Saves a Life

Here's a nice story for Parshat Lech Lecha.

Ladaat and Kikar both report about a Jewish guy who lives in Vinnytsia, Ukraine, who was diagnosed with a very serious heart condition.  He went to his rabbi, Rabbi Sha'ul Halevi Horowitz, who suggested to him to undergo a Berit Mila.  He decided at that moment to do so.
After a few checkups, the felt better, and soon afterwards, his doctors gave him a clean bill of health.  Not long afterwards, he underwent a Berit Mila and was given the Jewish name of David.

Mazal Tov!
