De novo atrial fibrillation post cardiac surgery: the Durban experience

Area of Science:

• Cardiology
• Cardiac Surgery
• Clinical Medicine

Background:

• Atrial fibrillation (AF) is a frequent complication following cardiac surgery.
• AF increases patient morbidity, mortality, and healthcare expenses.
• Effective management strategies are crucial, especially in resource-limited settings.

Purpose of the Study:

• To describe the local experience of new-onset AF after cardiac surgery.
• To inform the development of an adapted local treatment policy for post-AF.
• To compare local findings with existing published data.

Main Methods:

• Pilot retrospective study of adult patients who developed de novo AF post-cardiac surgery.
• Data collected from a Durban-based cardiac surgical unit between 2009 and 2012.
• Analysis of patient records to identify AF onset, treatment, and outcomes.

Main Results:

• Fifty-nine patients developed AF, predominantly occurring three or more days post-surgery.
• Thirty-five patients required cardioversion and amiodarone for rhythm restoration.
• Patients developing AF experienced a 4.6-day longer return to the general ward (RGW).

Conclusions:

• Current practice favors liberal peri-operative beta-blocker and statin use over formal prophylaxis.
• Post-cardiac surgery AF significantly impacts length of stay and resource utilization.
• Randomized controlled trials are needed to assess interventions for reducing AF-related morbidity and prolonged hospital stays in resource-constrained environments.
