INTRODUCTION: A fragmented QRS (fQRS) is reported to be associated with a poor prognosis or sudden cardiac death (SCD) in patients with Brugada syndrome or ischemic heart disease. However, no studies have clarified the impact of the presence of an fQRS on SCD or ventricular arrhythmic events in patients receiving cardiac resynchronization therapy (CRT). This study aimed to clarify this point in patients with non-ischemic cardiomyopathy. METHODS AND RESULTS: This study included 137 heart failure patients with non-ischemic cardiomyopathy who received CRT (NYHA functional class: II/III/IV = 25/84/28)...

BACKGROUND: The choice of cardiac resynchronization therapy device, with (CRT-D) or without (CRT-P) a defibrillator, in patients with heart failure largely depends on the physician׳s discretion, because it has not been established which subjects benefit most from a defibrillator. METHODS: We examined the annual trend of CRT device implantations between 2006 and 2014, and evaluated the factors related to the device selection (CRT-D or CRT-P) for primary prevention of sudden cardiac death in patients with heart failure by analyzing the Japan Cardiac Device Treatment Registry (JCDTR) database from January 2011 and August 2015 (CRT-D, n=2714; CRT-P, n=555)...

BACKGROUND: There still is no evidence which neoadjuvant therapy regimen for stage II-III rectal cancer is superior. The aim of this study was to compare results achieved after long-course chemoradiotherapy (CRT) with short-term radiotherapy (RT) followed by delayed surgery. METHODS: A randomized trial was carried out between 2007-2013. One hundred fifty patients diagnosed with stage II-III rectal cancer were randomized into one of two neoadjuvant treatment arms: conventional chemoradiotherapy (CRT) and short-term radiotherapy (RT) followed by surgery after 6-8 weeks...

REVIEW
Jean-Claude Daubert, Raphaël Martins, Christophe Leclercq
Both cardiac resynchronization therapy with a pacemaker (CRT-P) and with a biventricular implantable cardioverter-defibrillator (CRT-D) are electrical treatment modalities validated for the management of chronic heart failure. There is no strong scientific evidence that a CRT-D must be offered to all candidates. Common sense should limit the prescription of these costly and complicated devices. The choice of CRT-P is currently acceptable. A direction to explore could be to downgrade from CRT-D to CRT-P at the time of battery depletion in patients with large reverse remodeling and no ventricular tachycardia and ventricular fibrillation detected...

BACKGROUND: Multiple studies have sought to determine variables associated with improved "response" to cardiac resynchronization therapy(CRT). Such variables, however, are often derived from inadequately controlled, single center cohort studies calling external validity into question. We sought to determine predictors of response to CRT-D and CRT-P utilizing the methods of systematic review. METHODS: We searched MEDLINE, Embase®, and the Cochrane Central Register of Controlled Trials (CENTRAL) from January 1, 1995, as this is the date of first article reporting use of CRT through October 20, 2014...

AIMS: Cardiac resynchronization therapy (CRT) with a defibrillator (CRT-D) has downsides of high cost and inappropriate shocks compared to CRT without a defibrillator (CRT-P). Recent data suggest that the survival benefit of implantable cardioverter defibrillator (ICD) therapy is attenuated in the older age group. We hypothesized that, among octogenarians eligible for cardiac resynchronization therapy, CRT-P confers similar morbidity and mortality benefits as CRT-D. METHODS AND RESULTS: We compared morbidity and mortality outcomes between consecutive octogenarian patients eligible for CRT therapy who underwent CRT-P implantation at Barzilai MC (n = 142) vs...

Persistent left superior vena cava is known to be a challenging anatomic abnormality for transvenous cardiac device implantation. In the a case of a young man presenting with dilative cardiomyopathy with severely impaired left ventricular ejection fraction (LVEF) and second-degree atrioventricular block (AV block), cardiac resynchronization therapy (CRT) with defibrillator (CRT-D) implantation was indicated. A transvenous approach was attempted, but placement of the right ventricular lead was not successful due to anatomic abnormalities...

A proportion of patients with head and neck cancer (HNC) experience significant swallowing difficulty during and post-radiotherapy/chemoradiotherapy (RT/CRT). Identifying patients during the pretreatment period who are anticipated to have compromised oral intake would allow for early and accurate patient education, and prioritisation of their management. Ascertaining a clear set of pretreatment predictors from the literature is challenging due to heterogeneity in study designs and patient cohorts, with minimal prospective data available (especially at 1-month post-treatment)...

Cardiac resynchronization therapy device (CRT-P and CRT-D) implantation has increased tremendously with increasing operator experience, eligible patients and expansion of indications. Refinements in devices and algorithms now aid physicians to improve biventricular pacing and optimize CRT. We report a case in which an interesting device program was used to achieve biventricular pacing after repeated dislodgement of the atrial lead in a patient implanted with CRT-D.
