Role of dynamic intraventricular obstruction and protective effect of beta-blocking therapy in left ventricular apical ballooning syndrome: A case report

This paper reports on a 58-year old woman with left ventricular apical ballooning syndrome (LVABS), who after interruption of beta-blocking therapy had a recurrence of symptoms and developed a severe dynamic left ventricular obstruction (LV-DYN-O) during sympathetic stimulation with dobutamine.
