Enhancing patient acceptance of ICD implantation through structured shared decision making: conversation is key.

Background: Implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-D) are lifesaving treatments for patients at risk for sudden cardiac death. Effective physician-patient communication during the shared decision-making process is essential. Electrophysiologist-patient conversations were targeted to obtain objective data on the interaction, understand the conversation framework, and uncover opportunities for improved communication.

Patients' attitudes and perceptions of implantable cardioverter-defibrillators: potential barriers to appropriate primary prophylaxis.

Background: Primary prophylaxis with implantable cardioverter-defibrillators (ICDs) improves mortality in patients at risk for sudden cardiac death (SCD). However, ICDs are highly underutilized. We explored patients' attitudes and perceptions of ICDs to better understand potential patient-related barriers to appropriate utilization.

Use of a screening tool improves appropriate referral to an electrophysiologist for implantable cardioverter-defibrillators for primary prevention of sudden cardiac death.

Background: Despite data showing the benefits of implantable cardioverter-defibrillator (ICD) insertion for primary prevention in populations at risk for sudden death, professional society guidelines recommending primary prevention, and recognition by payers of the clinical value of ICDs in these populations, ICDs for primary prevention remain underused. We sought to determine whether implementing a screening tool would increase appropriate identification of patients showing clinical evidence of ICD benefit and prompt referral to an electrophysiologist for ICD implantation.

Methods And Results: Screening tools were affixed to medical records for patients seen in 2 outpatient cardiology offices that queried ejection fraction and whether referral to an electrophysiologist was made (N=6632).

Randomized, single-blind, placebo-controlled pilot study of catheter-based myocardial gene transfer for therapeutic angiogenesis using left ventricular electromechanical mapping in patients with chronic myocardial ischemia.

Background: Catheter-based myocardial gene transfer (GTx) has not been previously tested in human subjects. Accordingly, we performed a pilot study to investigate the feasibility and safety of catheter-based myocardial GTx of naked plasmid DNA encoding vascular endothelial growth factor-2 (phVEGF-2) in patients with chronic myocardial ischemia.

Methods And Results: A steerable, deflectable 8F catheter incorporating a 27-guage needle was advanced percutaneously to the left ventricular myocardium of 6 patients with chronic myocardial ischemia.
