Matryoshka Valve-Stack T-Shirt — “Valve-in-Valve-in-Valve” Nesting Dolls Tee

VALVE-IN-VALVE-IN-VALVE. There's always room for one more.

On the front is a row of nested matryoshka dolls, each hiding a valve inside a valve. Russian dolls had valve-in-valve figured out centuries ago. Structural cardiology just needed a while to catch up.

On the back: "THERE'S ALWAYS ROOM FOR ONE MORE." True for redo TAVI. Also true for the case list at 6 p.m. on a Friday, the queue at the cath lab coffee machine, and the "quick add-on" from the ward.

Before you add the third doll, check the CT: annulus, coronary heights, sinus width. We skipped that step. Dolls don't have coronaries.

The fabric is light at 4.3 oz and layers easily under a scrub jacket or a fleece. It fits like a well-sized valve: no paravalvular leak, no patient–prosthesis mismatch.

Made for the cath lab.
