Theme 1: Management of anti-coagulation around electrophysiology procedures

BRUISE CONTROL-2 Study- a multicentre randomized controlled trial to investigate whether a strategy of Continued versus Interrupted novel oral anti-coagulant (NOAC) at the time of device surgery, in patients with moderate to high risk of arterial thrombo-embolic events, leads to a reduction in the incidence of clinically significant hematoma.

OCEAN Study- a multicentre randomized controlled trial to investigate whether a strategy of ongoing, long term oral anticoagulation is superior to a strategy of antiplatelet therapy (ASA) alone on the incidence of cerebral embolic events in moderate risk patients post-successful catheter ablation for atrial fibrillation.

Theme 2: Optimizing arrhythmia device therapy for cardiac patients

Image-HF-Project IIA study- a multicentre-cohort registry of patients clinically referred for primary prevention implantable cardioverter-defibrillator ICD with or without cardiac resynchronization therapy (CRT). Delayed Enhancement MRI (DE-MRI) is being used as an aid in the prognostic utility of scar quantification techniques in predicting arrhythmic cardiac events and in assessing the predictive utility of scar volume and distribution in clinical response rates to CRT.

RAFT-PermAF study- a multicentre randomized controlled trial to determine whether cardiac resynchronization therapy (CRT) will reduce all-cause mortality or hospitalization for heart failure in patients with permanent atrial fibrillation and mild to moderate heart failure when compared to ICD therapy alone.

MAPIT CRT study- a multicentre randomized controlled trial to determine whether MRI-guided placement (using LV remodelling criteria) of the ventricular leads at the time of CRT device implant will result in improved CRT response in patients as compared to standard lead placement.

AdaptResponse study- a multicentre randomized controlled post-market trial to compare CRT devices containing the AdaptivCRT software algorithm to standard CRT devices in reducing all-cause mortality and intervention for heart failure decompensation in patients receiving a CRT implant.

RASP study- a multicentre randomized controlled trial to examine whether right ventricular (RV) septal pacing has any different effect on left ventricular function than RV apical pacing in patients who require a pacemaker.

Theme 3: Cardiac sarcoidosis

CHASM-CS study- a multicentre cohort registry study investigating cardiac sarcoidosis as the underlying cause for unexplained new onset significant cardiac electrical conduction system disease in patients less than 60 years of age, or patients with idiopathic sustained ventricular tachycardia.  The study is also following patients diagnosed with pulmonary or systemic sarcoidosis who have an abnormal ECG or holter or echo test.  The study will follow the clinical outcomes in these patients and assess the role of advanced imaging  in diagnosis and guiding treatment.
