We report the case of a 51-year-old patient with Brugada syndrome (BrS) who experienced inappropriate shock due to T-wave oversensing (TWOS) during exercise when the optimal sensing vector was selected based on the automatic analysis by a subcutaneous implantable cardioverter-defibrillator (S-ICD). After selecting another vector during exercise testing, TWOS did not re-occur. Selection of appro...

A Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) has proven the efficacy of prophylactic implantable cardioverter defibrillator (ICD) use for chronic heart failure pa‐ tients without sustained ventricular tachycardia (SVT) and a history of ventricular fibril‐ lation, not restricted in those with myocardial infarction [1]. Since ICD is an expensive device, risk stratification is required...

Background—Cardiac resynchronization therapy (CRT) plus implantation of an implantable cardioverter defibrillator (ICD) reduced the risk of death or heart failure event in patients with mildly symptomatic heart failure, left ventricular dysfunction, and wide QRS complex compared with an ICD only. We assessed echocardiographic changes in patients enrolled in the MADIT-CRT trial (Multicenter Auto...

We report the case of a young man who accidentally received a prolonged electric discharge from electrical wires and released the electric source with the help of an inappropriate shock from his implantable cardioverter-defibrillator (ICD), after misinterpretation of the electrical signal by the device as a ventricular tachycardia. This case illustrates the "electrical noise" phenomenon, and un...

We report a case of a 37-year-old woman with arrhythmogenic right ventricular cardiomyopathy (ARVC), after implantation of a cardioverter-defibrillator (ICD), who was admitted to our hospital because of focal infarctions in the right kidney and in the spleen. Echocardiography showed thrombi on the ICD electrode and the presence of patent foramen ovale. Patent foramen ovale was successfully clos...

The usage of Implantable Cardiac Defibrillator (ICD) since 1980s is becoming more popular these days. The rate of both, endocarditis and constrictive pericarditis are low but it still needs attention. We are reporting a rare case of ICD endocarditis as a result of toe infection in a diabetic patient. This was followed by infectious pericarditis after device removal by open heart surgery and the...

BACKGROUND The subcutaneous implantable cardioverter-defibrillator (S-ICD) was developed to defibrillate ventricular arrhythmias, avoiding drawbacks of transvenous leads. The global EFFORTLESS S-ICD (Evaluation oF FactORs ImpacTing CLinical Outcome and Cost EffectiveneSS of the S-ICD) registry is collecting outcomes in 985 patients during a 5-year follow-up. OBJECTIVES The primary goal of the...

Transvenous implantable cardioverter-defibrillator (ICD) lead development was an important advance in arrhythmia management. Their evolution has been critical to the wide acceptance of ICDs for the treatment of ventricular arrhythmias and the prevention of sudden cardiac death. Indeed, it is unlikely that the 20-fold increase in annual ICD implants observed during the past 15 years would have o...
