Mortality and Cerebrovascular Events After Heart Rhythm Disorder Management Procedures

Area of Science:

• Cardiology
• Electrophysiology
• Patient Safety

Background:

• Quality improvement in electrophysiology requires understanding patient outcomes after heart rhythm disorder management (HRDM).
• Assessing death and cerebrovascular events (CVEs) after HRDM procedures is crucial for developing better care standards.
• This study analyzes hard, patient-centered outcomes following HRDM over a 17-year period.

Purpose of the Study:

• To assess and characterize the rates and causes of death and CVEs after HRDM procedures.
• To evaluate outcomes across various HRDM procedures including ablation and device implantation.
• To identify specific risks associated with different types of HRDM procedures.

Main Methods:

• A retrospective cohort study included 48,913 patients undergoing 62,065 HRDM procedures from 2000 to 2016.
• In-hospital deaths and CVEs were identified and categorized as directly or indirectly related to the procedure.
• Subgroup analyses examined rates for ablation, device implantation, electrophysiology studies, lead extraction, and defibrillation threshold testing.

Main Results:

• Overall mortality and CVE rates were 0.36% and 0.12%, respectively.
• Lead extraction procedures showed the highest mortality (1.9%) and CVE (0.62%) rates.
• Cardiac tamponade (40%) was the most frequent direct cause of death, predominantly in device implantation procedures.

Conclusions:

• Device implantation procedures accounted for nearly half of HRDM-related deaths, with cardiac tamponade as the primary cause.
• The findings underscore the need for enhanced protocols for rapid identification and management of cardiac tamponade, even in perceived lower-risk procedures.
• Improving patient safety in HRDM requires focused attention on specific procedural risks and complications.
