The gulf implantable cardioverter-defibrillator registry: Rationale, methodology, and implementation

Abstract

Background:The implantable cardioverter-defibrillator (ICD) is effective in the prevention of sudden cardiac death in high-risk patients. Little is known about ICD use in the Arabian Gulf. We designed a study to describe the characteristics and outcomes of patients receiving ICDs in the Arab Gulf region.Methods:Gulf ICD is a prospective, multi-center, multinational, and observational study. All adult patients 18 years or older, receiving a de novo ICD implant and willing to sign a consent form will be eligible. Data on baseline characteristics, ICD indication, procedure and programing, in-hospital, and 1-year outcomes will be collected. Target enrollment is 1500 patients, which will provide adequate precision across a wide range of expected event rates.Results:Fifteen centers in six countries are enrolling patients (Saudi Arabia, United Arab Emirates, Kuwait, Oman, Bahrain, and Qatar). Two-thirds of the centers have dedicated electrophysiology laboratories, and in almost all centers ICDs are implanted exclusively by electrophysiologists. Nearly three-quarters of the centers reported annual ICD implant volumes of ≤150 devices, and pulse generator replacements constitute <30% of implants in the majority of centers. Enrollment started in December 2013, and accrual rate increased as more centers entered the study reaching an average of 98 patients per month.Conclusions:Gulf ICD is the first prospective, observational, multi-center, and multinational study of the characteristics and, the outcomes of patients receiving ICDs in the Arab Gulf region. The study will provide valuable insights into the utilization of and outcomes related to ICD therapy in the Gulf region.

Developing a Minimum Data Set (MDS) for Cardiac Electronic Implantable Devices Implantation

“…Pacemaker and cardioverter defibrillators are increasingly recognized as efficient tools for management of cardiac rhythm disorders. Pacemakers, which are capable to send electrical impulses via intracardiac conductors to avoid Brady arrhythmias; the implantable cardioverter-defibrillator (ICD), which is effective in the inhibition of sudden cardiac death (SCD) through programmable anti-tachycardia pacing and/or DC shocks; and CRT devices, which are able to perform right and left ventricular pacing, usually in synchrony, to resynchronize ventricular contraction in patients with heart failure and conduction disturbances ( 10 , 11 ). In this context, in order to establishing and maintenance a comprehensive information management system, existence of minimum dataset is essential.…”
