Long-Detection Programming in Single-Chamber Implantable Cardioverter Defibrillators Reduces Shocks and PacingMay 17, 2017
Long-detection programming improved survival, decreased the likelihood of hospitalization, and reduced therapy in patients with single-chamber ICDs.
None of the patients had device failure during the MRI; however, 6 patients did have atrial fibrillation or flutter but each case stopped on its own.
Nearly half of all implantable cardioverter defibrillator shock events utilized health care.
Cardiac resynchronization therapy with defibrillation correlated with reduced hospitalization or all-cause mortality and all-cause mortality in advanced systolic heart failure.
Of 307 patients, only 1 patient's ICD had electromagnetic interference produced by a telephone.
In older adults who received implantable cardioverter-defibrillators as secondary prevention of sudden cardiac death, the risk of death was 21.8%.
St. Jude Medical implantable cardiac devices and the Merlin@home Transmitter may be vulnerable to cybersecurity attacks.
Researchers conducted a study to determine the risk of VT/VF using wearable cardioverter defibrillators after ICD explantation.
Complication rates were 13.7% and 18.0%, respectively, in the subcutaneous ICD and transvenous ICD groups and infection rates were 4.1% vs 3.6%.
Anticoagulation therapy may not reduce stroke risk for patients with ICDs who have only brief episodes of AT or AF.
Implantable cardioverter defibrillators and cardiac resynchronization therapy defibrillators manufactured by St. Jude Medical may have batteries that will prematurely deplete.
Cardiac recovery was independently predicted by age, nonischemic cardiomyopathy, time from cardiac diagnosis, lack of ICD, serum creatinine levels, and LV end-diastolic dimensions.
Previously abandoned leads were associated with more complications from infection.
Safety and efficacy of exercise training in patients with heart failure with implantable cardioverter defibrillators.
Of the 556 patients assigned to receive an ICD, 120 died compared with 131 in the control group who received usual care.
Updated analyses and insights from the first cardiac resynchronization therapy-heart failure mortality/morbidity trial comparing defibrillator or pacemaker with pharmacologic therapy alone.
Catheter Ablation vs Antiarrhythmic Drug Escalation Therapy in Patients With Ventricular TachycardiaMay 05, 2016
The catheter ablation group experienced a significantly lower rate of the primary outcome compared with the escalated therapy group.
Researchers analyzed the performance of 3 types of implantable cardioverter-defibrillators: single-chamber, dual-chamber, and cardiac resynchronization therapy devices.
The biventricular pacing arm showed greater improvement in New York Heart Association functional class at 12 months.
Risk of thromboembolic complications was 5 times higher among patients without therapeutic anticoagulation during cardioversion.
Two studies suggest that atrial fibrillation results in reduced physical activity among older adults.
Results indicated that the rate of patients who received bystander CPR increased at home and in public first-responder defibrillation increased at home but not in public.
Wearable cardioverter-defibrillators are reasonable bridges to more "definitive therapy" or in situations associated with increased risk of death in which implantable defibrillators reduce sudden cardiac death but not overall survival.
Few patients with implantable cardioverter defibrillators are aware that they can deactivate their devices in their final days to avoid painful shocks.
Possible Mechanisms Behind Implantable Cardioverter Defibrillator Lead Malfunctions After LVAD ImplantationMarch 25, 2016
Lead malfunctions in implantable cardioverter defibrillators following left ventricular assist device implantation do occur, but may improve over time.
Patients with heart failure with reduced ejection fraction who received any guideline-directed medical therapy were less likely to die within 1 year of implantable cardioverter-defibrillator placement.
Cardiac resynchronization therapy with defibrillator therapy was associated with a greater increase in relative wall thickness compared with implantable cardioverter-defibrillator therapy.
