Mitral aortic intervalvular fibrosa or aorto‐mitral curtain is a fibrous avascular skeletal structure located between the anterior leaflet of the mitral valve and the non‐coronary and left coronary cusps of the aortic valve. Mitral and aortic valve endocarditis are rarely accompanied by mitral aortic intervalvular fibrosa pseudoaneurysm and left atrial fistula of the aorta. Pseudoaneurysm of mitral aortic intervalvular fibrosa is a fatal complication that can occur after valvular surgery, valvular endocarditis, or blunt trauma. In this article, reconstructive surgical management with the Commando technique of a case who developed mitral‐aortic intervalvular fibrosa pseudoaneurysm to left atrial fistula after aortic and mitral prosthetic valve endocarditis is described. The important feature of this article is that it is a first in the literature as it is accompanied by persistent left superior vena cava.
