The clinical challenge of concomitant aortic and mitral valve stenosis.

The coexistence of mitral and aortic stenosis is not exceptional. Whereas rheumatic fever is currently plummeting in the Western countries, the incidence of degenerative disease is inversely increasing. The haemodynamic interactions which may interfere both with the usual echocardiographic parameters and with the invasive assessment may render the diagnosis difficult. The therapeutic challenges raised by this entity should not be underestimated. The increased morbidity and mortality of multivalvular surgery has to be balanced with the risk of a second operation down the line if one valvular involvement, deemed of a lesser importance, is neglected. This complex situation requires the multidisciplinary approach of a heart team involving surgeons, cardiologists, geriatrists if need be and imaging specialists.
