Coronary sinus diverticulum complicating CRT device implantation

Area of Science:

• Cardiology
• Cardiac Electrophysiology
• Medical Imaging

Background:

• Coronary sinus diverticula are uncommon congenital anomalies.
• They are often found incidentally during cardiac procedures.
• Association with accessory pathways is noted in literature.

Observation:

• A 74-year-old male patient underwent cardiac resynchronization therapy (CRT) device implantation.
• Coronary sinus diverticulum was identified during the attempted selective cannulation of the coronary sinus for left ventricular lead placement.
• This finding was incidental to the primary procedure.

Findings:

• The coronary sinus diverticulum did not impede the successful implantation of the CRT device.
• The procedure, including left ventricular lead placement, was completed without any immediate complications.
• This case demonstrates the feasibility of proceeding with CRT implantation despite an incidental coronary sinus diverticulum.

Implications:

• Incidental coronary sinus diverticula may not contraindicate cardiac device implantation.
• Careful procedural planning and execution are crucial in managing such anatomical variations.
• Further research may clarify the long-term implications and management strategies for coronary sinus diverticula in patients undergoing cardiac device therapy.
