RESUMO
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

Over a period of years general anesthesia has been a standard anesthetic technique for defibrillation threshold [DFT] testing at the time of implant. DFT testing without general anesthesia cover has gained limited acceptance. Use of local anesthesia combined with deep sedation for DFT testing might facilitate and simplify these procedures by reducing the procedural time, staff time, avoiding inefficient service in organizing anesthetic cover; thereby improving patient compliance. The objective of this study was to evaluate feasibility, safety and efficacy of conscious sedation for DFT testing during Implantable cardioverter defibrillators [ICD] implantation. Data of 87 non-selected patients who achieved adequate sedation with titrated doses of midazolam and pethidine were analyzed retrospectively. These medications were administered by a circulating nurse under the supervision of the implanting physicians. All hemodynamic measures, treatment and complications were monitored and recorded throughout the procedure. A retrospective analysis of data from 87 patients who underwent ICD implantation and DFT testing under conscious sedation at our center was reported. The mean dose of midazolam and pethidine administered was 4.9 +/- 1.8 and 47.7 +/- 20 mg, respectively. During the period of conscious sedation, no patient depicted episode of sustained apnea. No major complication or mortality was reported. Use of conscious sedation as an alternative to the use of general anesthesia for DFT testing during ICD implantation is found to be feasible, safe and effective, with an added advantage of reduced procedural time and improved patient compliance
