On March 11, 1960, 32 year old Nina Braunwald made history when she became the first cardiac surgeon of either sex to replace the mitral valve. 1 Men have outnumbered women in modern medicine for several decades now. This is quite evident in surgical specialties and glaringly stark in cardiac surgery. 2 A line that encapsulates the real issue that all female cardiac surgeons face is: 'It isn't just a glass ceiling that needs to be cracked, it's a broken ladder that you'll have to climb to get to it'. Nina Braunwald, the first female cardiac surgeon, made headlines during a time when almost all specialty surgeons were men. Individual talent and drive alone did not guarantee a woman entry into cardiothoracic surgery. This was an era in which Helen Taussig, a female pioneer in paediatric cardiology, had been barred from cardiac surgical training at both Harvard and Hopkins. 3 Nina Braunwald (1928-1992) was no ordinary woman. She was the first woman to perform open-heart surgery and was the first surgeon of either sex to perform a mitral valve replacement. She was also the first woman to be elected to the American Association for Thoracic Surgery. 4
