Real-world evaluation of follow-up strategies after ICD therapies in patients with VT (REFINE-VT)

Patrick Tran, Leeann Marshall, Ian Patchett, Handi Salim, Shamil Yusuf, Sandeep Panikker, Michael Kuehl, Faizel Osman, Prithwish Banerjee, Harpal Randeva, Tarvinder Dhanjal

Abstract

Introduction Implantable cardiac defibrillators (ICDs) have become the cornerstone in preventing sudden cardiac death in susceptible patients or survivors of malignant ventricular arrhythmias (VAs).1-3 Although they terminate VA and improve survival, there is still a risk of recurrent VAs and ICD shocks, which are associated with profound psycho-social stress, worsening heart failure (HF) and increased mortality.2-4 Several strategies are available to address this, with specific advantages and risks. Programming to delayed-detection therapy windows can attenuate ICD therapy risk, but do not completely eliminate shocks.5 Anti-arrhythmic drugs

Loperamide-induced ventricular tachycardia storm

Mohamed Daoub, Philippa Cawley, Jonathan Sahu

Abstract

Introduction Loperamide-induced cardiac toxicity is rare but potentially fatal. We describe a case of long-term overdose in a vulnerable young adult, leading to a near-fatal cardiac event. Case A 34-year-old woman was referred to a tertiary centre cardiology team with multiple episodes of pulseless ventricular tachycardia (VT) requiring direct current (DC) cardioversion. The patient initially presented to a district general hospital (DGH) with a seizure preceded by palpitations. In the emergency department (ED) she had three witnessed episodes of pulseless VT, each requiring a single 200 J shock before achieving return of spontaneous circulat

Torsades de pointes cardiac arrest associated with severe hypothyroidism

Jakub Lagan, Louise Cutts, Diane Barker, Peter Currie

Abstract

Background Hypothyroidism is a common endocrine disorder, which has a variety of effects on the cardiovascular system including decreased cardiac output, increased systemic vascular resistance, accelerated atherosclerosis and rhythm disturbances, such as sinus bradycardia, conduction defects or non-specific ST changes.1,2 Hypothyroidism can also cause prolongation of the QTc interval and ventricular arrhythmias.1 Case presentation A 76-year-old woman was admitted to our hospital with a collapse, and while in the emergency department she sustained a witnessed cardiac arrest secondary to torsades de pointes (TdP) (figure 1). This was terminated

A single defibrillation safety margin test is sufficient in most ICD patients: experience from a UK tertiary centre

A single defibrillation safety margin test is sufficient in most ICD patients: experience from a UK tertiary centre

Faizel Osman, Abubakar Habib, Mohamed Jeilan, Suman Kundu, Jiun Tuan, Rajkumar Mantravadi, J Douglas Skehan, Peter J Stafford, Ravi K Pathmanathan, G Andre Ng 

Abstract

We retrospectively evaluated our ICD database between September 2006 and October 2007 to determine baseline patient/procedure characteristics and details of defibrillation threshold assessment during implant. All patients underwent at least two defibrillation safety margin (DSM) tests (≥10 J below the maximum output of the device). Logistic regression analysis was performed to identify factors predicting two successful consecutive DSM tests (with ≥10 J safety margin). A total of 264 procedures were performed (mean age ± standard error: 65.6 ± 0.8 years); 258 (97.7%) patients had successful first DSM test (with ≥10 J safety margin),
