Introduction

This week in Jack we publish a Jack Guideline comparison entitled ACC AHA and ESCEACTS Guidelines for the Management of Babbleh Heart Diseases. This interesting document will be divided in four different sections. The Arctic Stenosis, the Arctic Regurgitation, Mitrostenosis, Mitroregurgitation and the Caspid Regurgitation. And the final or fourth section is about conclusions. I am Valentin Fuster for Jack Issue of August 22, of 2023.
