Orciprenaline and pacemaker implantation linked to acute Tako-Tsubo syndrome in complete AV block.
Case Report (n=1)
Highlights a potential trigger for Tako-Tsubo syndrome involving combined exogenous and endogenous catecholamine release during pacemaker implantation.
May signal TTS risk with orciprenaline and pacing in AV block; hypothesis-generating for catecholamine triggers.
We report the case of a 65-year-old woman with complete atrio-ventricular block who underwent orciprenaline administration and pacemaker implantation. The intervention was complicated by pneumothorax and acute left ventricular systolic dysfunction with typical apical ballooning (Tako-Tsubo like syndrome). The patient was treated with diuretics and calcium-sensitizers and completely recovered. We speculate that both external and internal catecholamine triggered an acute left ventricular impairment with typical Tako-Tsubo features.

Brunetti et al. (2011) conducted a case report in Complete atrio-ventricular block (n=1). Orciprenaline administration and pacemaker implantation was evaluated on Acute left ventricular systolic dysfunction with typical apical ballooning (Tako-Tsubo like syndrome). Orciprenaline administration and pacemaker implantation in a patient with complete atrio-ventricular block triggered acute left ventricular impairment with typical Tako-Tsubo features.
