KUALA LUMPUR, 5 JUNE 2026 — Institut Jantung Negara (IJN) has achieved another significant milestone in cardiovascular care by becoming the first hospital in Malaysia to introduce and utilise the innovative TactiFlex™ Duo Ablation Catheter. The advanced dual-energy cardiac ablation technology is designed to treat complex heart rhythm disorders, including atrial fibrillation and ventricular arrhythmias, offering physicians greater flexibility and precision in managing challenging cardiac conditions.

The introduction of the TactiFlex™ Duo Ablation Catheter further strengthens IJN’s position as the nation’s leading heart centre and referral institution for complex cardiovascular cases. As heart rhythm disorders continue to affect a growing number of patients worldwide, the availability of advanced treatment technologies plays a crucial role in improving patient outcomes and expanding therapeutic options.

Cardiac ablation is a minimally invasive procedure used to treat abnormal electrical pathways in the heart that cause irregular heartbeats. What sets the TactiFlex™ Duo Ablation Catheter apart from conventional systems is its ability to deliver two different forms of energy within a single procedure. Physicians can utilise both radiofrequency (RF) energy and pulsed field ablation (PFA) energy depending on the patient’s anatomy, tissue characteristics, and clinical requirements. This dual-energy capability allows for a more personalised and targeted treatment approach.

Radiofrequency energy works by applying controlled heat to eliminate problematic heart tissue responsible for abnormal electrical signals, while pulsed field ablation uses high-energy electrical pulses to selectively target cells causing irregular heart rhythms. The combination of these technologies enables physicians to adapt treatment strategies in real time, enhancing procedural flexibility and potentially reducing the impact on surrounding healthy tissue in suitable patients.


According to Datuk Dr. Azlan Hussin, Clinical Director of Interventional Electrophysiology and Implantable Devices as well as Senior Consultant Cardiologist at IJN, the introduction of the technology represents an important advancement in the treatment of complex arrhythmias. He explained that no two patients present identical cardiac conditions, making personalised treatment increasingly important in modern electrophysiology. The ability to switch between RF and PFA during procedures allows specialists to optimise treatment based on individual patient needs, particularly when managing complex cases such as atrial fibrillation and ventricular tachycardia.

For patients who continue to experience symptoms despite medication or conventional therapies, the TactiFlex™ Duo Ablation Catheter offers access to a more advanced minimally invasive treatment option. By accurately targeting the source of abnormal heart rhythms, successful ablation procedures may help reduce symptoms, improve quality of life, and support better long-term cardiac outcomes.

Importantly, the new technology complements rather than replaces IJN’s existing cardiac ablation systems. By expanding the range of treatment tools available to electrophysiologists, the institution can select the most appropriate therapeutic approach for each patient, ensuring highly individualised care tailored to specific clinical goals.


IJN Chief Executive Officer, Prof Dato’ Sri Dr. Mohamed Ezani Md Taib, emphasized that the introduction of the TactiFlex™ Duo Ablation Catheter reflects the institution’s ongoing commitment to bringing advanced cardiovascular technologies into clinical practice. He noted that innovation remains meaningful only when it translates into improved patient care, safety, and outcomes. Through continued investment in cutting-edge technologies and specialised expertise, IJN aims to ensure that patients in Malaysia have access to world-class treatment options for complex cardiovascular conditions.

The launch also reinforces IJN’s standing as a centre of excellence for heart rhythm management, supported by multidisciplinary expertise, advanced imaging and mapping technologies, and a dedicated interventional electrophysiology team. By combining clinical excellence with innovative medical devices, IJN continues to advance the standards of specialised cardiac care not only in Malaysia but across the region.

As cardiovascular diseases remain one of the leading health challenges globally, the adoption of technologies such as the TactiFlex™ Duo Ablation Catheter demonstrates how innovation can help improve treatment precision, expand therapeutic possibilities, and deliver more effective patient-centred care for those living with complex heart rhythm disorders.
