[Intraventricular transient obstruction related to bronchodilator treatment].
A 66-year-old woman with a previous history of chronic lung disease, without evidence of heart disease and without signs of left ventricular hypertrophy developed a dynamic intraventricular obstruction documented by a Doppler-derived gradient of 25 mmHg and by physical signs consisting of a brisk carotid pulse and a harsh systolic murmur while she was on treatment with theophylline and hexoprenaline. Both physical signs and Doppler-derived gradient disappeared after withdrawal of bronchodilator drugs.
