“…Inappropriate sensing by S-ICD devices can be problematic, with 7%–15% of patients failing initial screening, 7 and a 7% annual rate of inappropriate shocks reported in an early S-ICD registry. 8 These were predominantly caused by T-wave oversensing and poor supraventricular tachycardia discrimination, which can be lowered by the addition of the Smart Pass filter 9 and dual-zone programming, 10 respectively.…”

“…By virtue of leaving the venous system untouched, this approach might offer the advantage of a reduced risk of central venous stenosis and infection over an endocardial ICD with transvenous leads [59]. Importantly, this device requires preimplant screening to ensure appropriate sensing and reduce the risk of inappropriate shocks [60]. Besides challenging vascular access (central veins stenosis, occlusion, AVF, or CVC for HD) and complications avoidance, the following indications for S-ICD placement should be considered: prior complications with transvenous ICDs, infection (bacteremia), and the young age of the ICD patient.…”

Cardiovascular implantable electronic devices (CIEDs) are a standard therapy utilized for different cardiac conditions. They are implanted in a growing number of patients, including those with chronic kidney disease (CKD) and end-stage kidney disease (ESKD). Cardiovascular diseases, including heart failure and malignant arrhythmia, remain the leading cause of mortality among CKD patients, especially in ESKD. CIED implantation procedures are considered minor surgery, typically with transvenous leads inserted via upper central veins, followed by an impulse generator introduced subcutaneously. A decision regarding optimal hemodialysis (HD) modality and the choice of permanent vascular access (VA) could be particularly challenging in CIED recipients. The potential consequences of arteriovenous access on the CIED side are related to (1) venous hypertension from lead-related central vein stenosis and (2) the risk of systemic infection. Therefore, when creating permanent vascular access, the clinical scenario may be complicated by the CIED presence on one side and the lack of suitable vessels for arteriovenous fistula on the contralateral arm. These factors suggest the need for an individualized approach according to different clinical situations: (1) CIED in a CKD patient; (2) CIED in a patient on hemodialysis CIED; and (3) VA in a patient with CIED. This complex clinical conundrum creates the necessity for close cooperation between cardiologists and nephrologists.

“…The previous manual process of assessment has been replaced by an automated screening tool, which helped standardizing and documenting this process. 15 While the manufacturer recommends at least one suitable vector, we generally aim for at least two out of the three vectors to be suitable in three positions (supine, sitting, and standing). This appears even more important in patients with hypertrophic cardiomyopathy or ion channel diseases.…”

Despite major advances in medical therapy, sudden cardiac death remains an important cause of cardiovascular mortality. In order to improve the risk‐benefit balance of transvenous implantable cardioverter‐defibrillator (ICD) systems, a totally subcutaneous ICD (S‐ICD) system was developed and approved for use in Europe in 2009. The currently available S‐ICD system has undergone several important hardware‐ and software‐related modifications and improvements over the last 10 years aimed at further improving its efficacy and safety. The results of the PRAETORIAN trial, that is, the first randomized comparison of S‐ICD versus transvenous ICDs, of the prospective UNTOUCHED study, and the overall consistent observational data underline that current generation S‐ICD systems may be a valid alternative in patients with an ICD indication in whom bradycardia pacing or cardiac resynchronization therapy is not required due to a lower risk of system‐related problems. This review summarizes the key differences between the two systems, improvements in hardware components and algorithms over time, as well as most recent clinical evidence regarding the efficacy and safety of the S‐ICD.
