Outcomes of cardiac-physiologic studies at Queen Alia heart institute : a three year experience

Abstract EN

Objective: To evaluate the outcomes of cardiac -physiologic studies and interventions for a variety of cardiac arrhythmias at Queen Alia Heart Institute and to compare our status with other cardiac units in multi-institutional centers.

Methods: The records of patients who had electro-physiologic studies at Queen Alia Heart Institute in the period between January 2014 and December 2016 were reviewed.

Endpoints included were: Early mortality, heart block, groin vascular complications and cardiac perforations.

Results: A total of Eight-hundred-twenty-five patients were included in this retro-spective study, 64% of the patients were males, and the age range in the whole cohort was between 9-86 years (mean 46 years).

The indications for the electro-physiologic studies were: Supra-ventricular tachycardia (505 patients), Wolf Parkinson White Syndrome (223 patients), Ventricular Tachycardia (22 patients), Sinus nodal dysfunction or atrio-ventricular nodal conduction disturbances (28 patients) and syncope (29 patients).

None of the 825 patients had early mortality.

Four patients developed complete heart block, 3 of them followed atrioventricular nodal reentrant tachycardia ablation while the fourth was after parahisian pathway ablation.

Three patients had groin hematomas, none of these needed surgical intervention.

One patient had cardiac perforation , and one patient had simple pneumothorax which was treated using tube thoracostomy.

The average in-hospital stay was 2 days.
