“…A recent study demonstrated that approximately 60% of the patients with a transvenous ICD without a preexistent indication for pacing could be suitable for S-ICD implantation. 10 This implies that, following our finding that 93% of the patients have an appropriate TMS-ECG, more than 50% of all ICD patients without a preexistent pacing indication could be eligible for S-ICD implantation. On the other hand, the S-ICD cannot be used as first line therapy in more than 7% of the patients, with even higher rates in selected populations such as HCM and obese patients.…”

In patients without an indication for pacing, 7.4% would have been not suitable for a S-ICD according to the TMS. HCM, a heavy weight, a prolonged QRS duration and a R:T ratio <3 in the ECG lead with the largest T wave were independently associated with TMS failure. These data might alert physicians that selection of patients for a S-ICD should be considered with special caution in certain patient groups, because they may not satisfy ECG criteria for adequate sensing.

“…This raises the question as to what proportion of patients who would qualify for an S-ICD would ultimately require pacing or ATP & hence need conversion of their device to a transvenous system. A recent Dutch study of ICD recipients reviewed 463 patients followed up over a median of 3.4 years between 2002-11 [28]. It was demonstrated that 55.5 % (95 % CI 52.0 % to 59.0 %) of single or dual chamber ICD recipients would have been suitable for an initial S-ICD implantation after 5 years, i.e.…”

The Subcutaneous Internal Cardiac Defibrillator (S-ICD) represents a major advance in the care of patients who have an indication for an internal cardiac defibrillator without pacing indications. Its main advantage is that it can deliver a shock to cardiovert ventricular arrhythmias utilising a tunnelled subcutaneous lead, negating the risks associated with conventional transvenous systems. Initial studies have shown comparable efficacy in cardioversion of induced and spontaneous ventricular tachycardia (VT) and ventricular fibrillation (VF) when compared to conventional transvenous systems. In addition, inappropriate shocks occurred in a similar percentage of patients to conventional ICD studies. Complication rates are low and relate largely to localised wound infections, treated successfully with antibiotics. The long term efficacy of the device is yet to be ascertained, however, a randomised trial & prospective registries are currently in progress to enable direct comparison with transvenous ICDs. This article summarises the early clinical experience and trials in the implantation of the S-ICD.

“…It becomes a less invasive option for patients in whom TV-ICD implantation is surgically impossible. It is estimated that up to 55% of patients in routine clinical practice needing an ICD are potential candidates for a subcutaneous device [14,15]. However, to maximize clinical outcome and cost/benefit ratio, it is fundamental to choose candidates that can benefit most, taking into account both patient and device characteristics.…”

Suitability for subcutaneous defibrillator implantation: results based on data from routine clinical practice

Abstract: After 5 years of follow-up, approximately 55% of the patients would have been suitable for an S-ICD implantation. Several baseline clinical characteristics were demonstrated to be useful in the selection of patients suitable for an S-ICD implantation.
