Major Publications

CAMERA-MRI Study

Sunny was the co-ordinator and principle author of this landmark Australian randomised clinical trial evaluating the role of catheter ablation in patients with AF and otherwise unexplained heart failure. This study was published in the Journal of the American College of Cardiology in 2017, and has since been incorporated into national and international treatment guidelines.

Atrial scarring in patients with atrial fibrillation and heart failure

Improvement in atrial scarring after catheter ablation or atrial fibrillation in heart failure. Long-Term Follow-Up of the CAMERA-MRI Study. This important study for the first time demonstrated that improvement in heart function following catheter ablation can improve scarring in the atria.

https://www.sciencedirect.com/science/article/pii/S2405500X19301720?via%3Dihub

Reversal of Heart Scarring in Heart Failure After Cather Ablation

This paper was the first to describe that scarring of the heart that occurs in a weakened heart muscle due to atrial fibrillation, can be reversed after successful catheter ablation.

https://electrophysiology.onlinejacc.org/content/4/8/999

Alcohol and Atrial Fibrillation

In concert with the Alfred and Baker, Sunny co-authored a landmark Australian clinical trial (led by colleague Dr Alex Voskoboinik) examining the role of alcohol in atrial fibrillation. This study was published in the world’s leading medical publication, the New England Journal of Medicine in 2020.

Catheter Ablation Versus Medication in Atrial Fibrillation and Systolic Dysfunction: Late Outcomes of CAMERA-MRI Study

This study demonstrated that the improvements in heart function seen in patients with atrial fibrillation and otherwise unexplained heart failure, was maintained in the long term out to 4 years. (Recently accepted in JACC: Clinical Electrophysiology – July 2020)

Currently Enrolling Clinical Trials

CAMERA-MRI II Study (RECRUITMENT COMPLETE)

This randomised clinical trial is a follow on study from CAMERA-MRI is evaluating the role of MRI detected heart scarring upon heart function after catheter ablation for atrial fibrillation in all patients with heart failure. This study is currently being conducted across several sites across Melbourne and the UK.

The WITHDRAW-AF Study (RECRUITMENT COMPLETE)

This randomised clinical trial plans to evaluate the need of ongoing heart failure medical therapy in patients with a fully recovered heart function following treatment of heart failure due to atrial fibrillation. This study will be performed across multiple sites in Melbourne and Internationally.

The SMART-AF Study (TO COMMENCE 2025)

This study looks to evaluate the role of smart device based applications to track risk factor modification in real time in patients with atrial fibrillation and multiple modifiable risk factors such as blood pressure, weight, alcohol intake, smoking, CPAP machine usage and diabetes control.
