Abstract
Abstract
Background
Cardiac implantable electronic devices have been known to have lead and device malfunctions leading to advisories. Increased use of remote monitoring of devices has been suggested to allow the identification of abnormal device performance and allow early intervention. We sought to describe the outcomes of patients with and without remote monitoring of in devices in the Abbott Premature Battery Depletion advisory with data from a Canadian registry
Methods
Patients with an Abbott device subject to the Battery Performance Alert Advisory from nine ICD implanting centres in Canada were included in the registry. The use of remote monitoring was identified from baseline and followup data in the registry. The primary outcome was detection of premature battery depletion and all cause mortality.
Results
2679 patents were identified with a device subject to the advisory. Devices were implanted between 2010 and 2017. 1716 patients (64%) had remote monitoring at baseline with this increasing to 83.7% at followup at 12 months. Premature battery depletion occurred in 43 patients (1.6%). Discovery of premature battery depletion was detected by remote monitoring in 70% of patients. There were 492 deaths during the follow up. Mortality was higher in those without a remote monitor compared to those with a remote monitor at follow-up and remote monitor at baseline and follow-up (11.3%, 2.6% versus 6.1% respectively; p=0.0186). There were no deaths attributed to premature battery depletion
Conclusion
The use of remote monitoring in patients with ICD and CRT under advisory reliably detected device failure and was associated with a reduction in all-cause mortality.

Abstract
The effect of standard cardiac resynchronisation therapy (CRT) on the severity of Cheyne-Stokes respiration (CSR) in patients with congestive heart failure was studied. It was hypothesised that CRT, through its known beneficial effects on cardiac function, would stabilise the control of breathing and reduce CSR. Twenty-eight patients who were eligible for CRT and receiving optimised medical treatment for congestive heart failure were referred for overnight polysomnography, including monitoring of thoracic and abdominal movements to identify CSR and obstructive sleep apnoea events. Patients underwent repeat polysomnography after 6 months of CRT to re-evaluate sleep quality and sleep-disordered breathing. Twelve of the 28 patients had significant CSR (43%); 10 patients had a successful implantation and underwent repeat polysomnography a mean+/-SD 27+/-7 weeks after continuous biventricular pacing. Six of the 10 patients experienced a significant decrease in CSR severity following CRT, associated with correction of congestive heart failure-related hyperventilation and hypocapnia. Circulation time, oxygen saturation, frequency of obstructive apnoeas and sleep quality did not change. In conclusion, cardiac resynchronisation therapy is associated with a reduction in Cheyne-Stokes respiration, which may contribute to improved clinical outcome in patients treated with cardiac resynchronisation therapy.

Abstract
The risk of cardioembolic events and the role of anti-coagulation therapy in the management of patients with lone atrial flutter is not well defined in the medical literature. We report the case of an otherwise healthy 42-year-old man with chronic established atrial flutter, unassociated with any other heart disease or systemic illness, with transesophageal echocardiographic findings of a mobile left atrial appendage thrombus. The literature to date, potential mechanisms, and recommendations are discussed. The role of transesophageal electrocardiography and anticoagulation in atrial flutter may need to be considered more seriously, especially if atrial flutter has been present for a prolonged period of time.

Abstract
OBJECTIVE To identify the relationship between the use of anticoagulants, specifically heparin, and the development of iliacus and psoas muscle hematoma. Three patients with unstable angina who developed groin pain while on heparin anticoagulation are presented. Patients who are anticoagulated with heparin are at increased risk of developing iliacus or psoas hematoma, manifesting a wide range of symptoms from groin pain to massive bleeding and shock. Identification of these patients is crucial in cardiology practice. DATA SOURCES MEDLINE searches under "iliacus', "psoas' and "iliopsoas hematoma' were conducted and cross-referenced with patients on anticoagulant therapy. Only English language articles were included. STUDY SELECTION The search covered January 1966 to February 1995. Fifty-one articles were studied. DATA SYNTHESIS The current literature suggests that anticoagulation can cause iliacus or psoas muscle hematoma and usually presents as femoral neuropathy. However, the presented case reports provide evidence that an earlier manifestation of this entity is the development of groin pain, and that early identification is crucial to improving patient morbidity and mortality. CONCLUSIONS Patients who are on heparin anticoagulation should be carefully monitored for development of groin pain or leg weakness. In such cases, early recognition of possible iliacus or psoas hematoma should be by abdominal ultrasound or computed tomography, and heparin anticoagulation should be modified according to its clinical requirement.
