MADIT-CRT Long-Term Follow-Up Shows Survival Benefit with CRT-D

MADIT-CRT was an influential trial that showed a reduction in heart failure complications — but not mortality — when cardiac resynchronization therapy (CRT) was added to an implantable defibrillator in patients with mild heart failure who also had left bundle-branch block (LBBB). Patients in the trial were followed for 2.4 years, raising questions about the long-term effects […]

Study Fails to Support Broader Patient Population for Cardiac-Resynchronization Therapy

A new study from the Echo-CRT study group shows that CRT is not beneficial in patients with HF and a narrow QRS complex and may even be harmful.

New Subcutaneous ICD Said to Pose ‘Existential Crisis’ for Older ICDs

Last year the FDA approved Boston Scientific’s subcutaneous ICD (S-ICD), the first ICD that doesn’t use transvenous leads. Those leads are the source of many sophisticated pacing features in today’s ICDs, but they are also the main source of ICD-related complications. FDA approval of the S-ICD was based on a pivotal trial designed to assess the […]

Study Finds Risks and Costs Associated with Infection After Device Implantation

A large new study has found significant risks and costs associated with infections following the implantation of CIEDs (cardiovascular implantable electronic devices), including ICDs, CRT-Ds, and pacemakers. In a paper published in Archives of Internal Medicine, Muhammad Sohail and colleagues analyzed Medicare data from more than 200,000 patients admitted for CIED implantation, replacement, or revision in 2007, including  5817 admissions with infection. Infection […]

Not Shocking: French Studies Evaluate Remote Monitoring of ICDs

Remote monitoring of ICDs can reduce inappropriate shocks, but the overall clinical benefit and cost-effectiveness of the technology has not yet been demonstrated, according to two new studies presented at the ESC meeting in Paris. Salem Kacet presented the ECOST (Effectiveness and Cost of ICD Follow-Up Schedule with Telecardiology) study in which 433 ICD patients were […]

A Life-RAFT for Patients with HF?

CardioExchange welcomes Arthur Moss, Professor of Medicine at the University of Rochester School of Medicine and lead investigator of the MADIT-CRT trial, to discuss his New England Journal of Medicine editorial on the RAFT trial, in which patients with mild-to-moderate HF were randomized to receive either an ICD alone or ICD plus CRT.  It seems […]

ICD-CRT Found Beneficial in RAFT

RAFT (Resynchronization-Defibrillation for Ambulatory Heart Failure Trial) randomized 1798 patients with NYHA class II or III heart failure, LVEF < 30%, and a wide QRS complex to either an ICD alone or an ICD-CRT. After a mean followup of 40 months, the rate of death or heart failure hospitalization was 40.3% in the ICD group […]
