What is the clinical significance of a faulty Assurity Pacemaker (from Abbott labs) with improper glue and epoxy mixture, leading to fluid leakage and a decreased heart rate of 30 beats per minute, in a 63-year-old male patient with hypertension, hyperlipidemia, and a history of atrial fibrillation, who underwent ablation and pacemaker insertion?

From the Guidelines

To determine the cardiologist's liability in the defective Assurity Pacemaker case, it is crucial to ask questions that establish their standard of care, knowledge of device defects, and the patient's impact, as the most recent and highest quality study suggests that complications with pacemakers can occur due to various factors, including manufacturing defects 1. When deposing the cardiologist who inserted the defective pacemaker, the following questions should be asked:

• About their experience with Abbott pacemakers and awareness of manufacturing issues from the Aricebo facility
• Their pre-procedure assessment of this 63-year-old male with hypertension, hyperlipidemia, and history of atrial fibrillation
• What specific indications led to selecting this particular pacemaker model and whether they were aware of any FDA alerts or manufacturer warnings about potential defects
• Their protocol for testing device functionality before implantation and what specific programming parameters were set initially
• Their post-procedure monitoring schedule and when they first noticed the pacemaker dropping to 30 beats per minute
• About their documentation of adverse events, communications with Abbott representatives, and what interventions they performed when the device malfunctioned
• Their understanding of how blood and fluid infiltration affects pacemaker function and what specific symptoms the patient experienced
• Their decision-making process regarding device replacement, timing considerations, and risk assessment for the revision procedure
• About their disclosure to the patient regarding the defective nature of the device and any conversations with Abbott about compensation or replacement
• Whether they've implanted other devices from the same manufacturing batch and what steps they've taken to monitor those patients Additionally, questions should be asked about:
• The cardiologist's knowledge of the guidelines for cardiac pacing and cardiac resynchronization therapy, as outlined in the European Society of Cardiology's task force report 1
• Their understanding of the risks of major complications, including cardiac perforation, hemothorax, pneumothorax, stroke, MI, and death, as reported in the American Heart Association's scientific statement 1
• Their experience with lead complications, which are the main reason for re-operation after implantation of PM or CRT devices, as reported in the European Heart Journal 1 The goal of these questions is to establish the cardiologist's standard of care and determine whether they deviated from it, which could have contributed to the patient's harm, as suggested by the study on complications of pacing and CRT 1.

Deposition Questions for the Cardiologist

The following questions can be asked to the cardiologist during the deposition:
