[Perioprocedural mortality after ICD implantation].

Area of Science:

• Cardiology
• Medical Device Technology
• Public Health

Background:

• Implantable cardioverter defibrillators (ICDs) are crucial for preventing sudden cardiac death.
• ICD implantation, like any surgery, carries inherent risks, including mortality.
• Understanding procedure-related mortality is vital for patient safety and quality assurance.

Purpose of the Study:

• To analyze the procedure-related mortality associated with ICD implantation.
• To identify patient demographics and clinical factors influencing mortality after ICD procedures.
• To utilize data from a mandatory quality assurance program for comprehensive analysis.

Main Methods:

• Analysis of 18,625 patient records from quality assurance datasets (2010-2012).
• Inclusion of all patients undergoing ICD implantation within the specified period.
• Statistical analysis to determine mortality rates and associated risk factors.

Main Results:

• Overall in-hospital mortality was 0.6% (118 patients).
• Increased mortality observed in patients over 80 years (1.9%), women (0.95%), and those with higher NYHA class (up to 3.4%).
• Renal failure requiring dialysis and secondary prevention indications significantly increased mortality risk.

Conclusions:

• Procedure-related mortality after ICD implantation is elevated in specific patient groups.
• Risk factors include advanced age, higher NYHA class, renal failure, secondary prevention, and perioperative complications.
• These findings underscore the importance of careful patient selection and risk management.
