Mitral Stenosis Presenting as Asthma.

Although wheezing is one of the most common symptoms and physical findings in asthma, other causes of wheezing should be kept in mind: vocal cord dysfunction, postnasal drip syndrome, chronic obstructive pulmonary disease, bronchiectasis, and non-pulmonary diseases, like heart failure and pulmonary edema. Here, we present a case of severe mitral stenosis with pulmonary edema treated for resistant asthma. If asthma is difficult to control, other etiologies of wheezing, including cardiac disease, should be taken into consideration during diagnosis.
