The mitral valve and mitral stenosis

The existence of the mitral valve is as old as the human race, but its nomenclature and clinicopathological recognition are no older than five centuries. The anatomical left atrioventricular valve was named the “mitral valve” by the Father of modern anatomy—Andreas Vesalius. In the second edition of De Humani Corporis Fabrica, published in 1555, he wrote that the mitral valve, when turned upside down, resembles a bishop’s miter (a two-flapped angled hat) (Figure 1.1) and gave an accurate description of mitral valve anatomy.1 In 1668, John Mayow from the Oxford school described the first patient of mitral stenosis with detailed clinical and pathological findings and was able to correlate clinical features with autopsy findings. Further, in 1705, Raymond de Vieussens scientifically detailed the clinical findings of a 30-year-old male patient of mitral stenosis.2 Later, when this patient died, he documented various pathological findings of mitral stenosis in his magnificent engravings:

I opened the left ventricle and I discovered here first that which I have just pointed out: namely the substance of the mitral valves has become bony and that it had very markedly diminished, and indeed changed the natural appearance of the lumen.

In 1806, Jean-Nicolas Corvisart described the thrill associated with mitral stenosis; he was the father of chest auscultation as well as the physician to Napoleon Bonaparte. Subsequently, in 1819, his pupil Rene H. T. Laennec, inventor of the stethoscope, described the murmur of mitral stenosis as “bruit de soufflet” (soft bellows).3 Many years later, Sulpice Antoine Fauvel, a French epidemiologist, described the precise timing and nature of the presystolic murmur in mitral stenosis.4 In 1862, Austin Flint provided precise and accurate descriptions of various cardiac murmurs,5 in particular a similar presystolic murmur at the apex in severe aortic regurgitation and a normal mitral valve, eponymously described as an Austin Flint murmur. In 1877, Paul Louis Duroziez described congenital mitral stenosis and made an etiological distinction between mitral stenosis of rheumatic and of congenital origin. He is also remembered for describing the Duroziez’s murmur in severe aortic regurgitation (Table 1.1).6

The surgical era

The idea of surgically opening the mitral valve was first visualized by Frederick Alexander Samways in 1898 (Figure 1.2),7 supported by Sir Lauder Brunton in 1902.8 In Samways’ own words, for the surgical treatment of mitral stenosis:

Figure 1.2Samways’ landmark paper in The Lancet, 1896.

I anticipate that with the progress of cardiac surgery some of the severest cases of mitral stenosis will be relieved by slightly notching the mitral orifice and trusting the auricle to continue its defence.

However, strong disapproval from contemporary physicians enforced a hasty retreat from the idea of surgery, which remained in cold storage for nearly 20 years. In 1923, an 11-year-old girl with mitral stenosis was successfully operated on by partial valve excision. She survived for nearly 5 years after the operation; however, the next five patients operated on by th...
