Description (Brief)
The development of artificial heart valves took place in many countries around the world, and created many international collaborations. This is a modified Smeloff valve developed in Italy. It has the same three metal prong and silastic ball design seen in many ball and cage designs. The valve was manufactured by Chirurgia Laboratorio and is a size 8. Attached is a letter written to Manny Villafana, dated June 2014, from Dr. Ugo Filippo:
"Dear Manny,/ Here is the valve I promised * (early sixties)/ It has never been used clinically./ Best regards/ ----/ Pronissio Probi viri est obligatio!"
