Put your hands together and say prayer for Leah Messer's mamaw (that's grandma, for all you Yankees), who is currently undergoing heart cath surgery.

The Teen Mom 2 star tweeted about the operation yesterday, asking fans for their love and support. "Everyone pray for my mamaw! She's having a [heart] Cath tomorrow!#GetWell Soon @mamawsandy56 !! I love you!!" she said.

A heart cath, which doctors refer to as a cardiac catheterization, involves the insertion of a flexible tube into the right or left chamber of the heart. The procedure is usually done to get information about the heart or its blood vessels, although sometimes may be performed to treat conditions such as coronary artery disease.

Surgery at any age is a risk, but especially for grandmas — which means this lovely lady needs all the prayers she can get. Take a moment to hop on Twitter and send your well wishes to Leah and her family. We're pulling for you, Mamaw!
