Summary: Fujifilm Healthcare Americas Corp. has launched the OPIE Transducer, facilitating real-time visualization of ventricular septal thickness during on-pump intracardiac echocardiography in septal myectomy surgery.

Key Takeaways

  • The OPIE Transducer allows surgeons to see ventricular septal thickness in real-time during septal myectomy surgeries, providing immediate feedback for adjustments.
  • Early studies suggest that the OPIE Transducer offers advantages over traditional imaging methods like transesophageal echocardiography (TEE) and transthoracic echocardiogram (TTE), potentially reducing the risk of complications such as ventricular septal defects.
  • Surgeons emphasize the importance of accurately measuring septal thickness during septal myectomy, as it directly impacts patient care pathways and outcomes, highlighting the clinical significance of the OPIE Transducer’s role in improving surgical precision.


Fujifilm Healthcare Americas Corp. has launched the OPIE Transducer, a new tool for real-time visualization of ventricular septal thickness during on-pump intracardiac echocardiography (OPIE) in septal myectomy surgery. Early clinical users will discuss its benefits at the 104th American Association for Thoracic Surgery meeting in Toronto from April 27-30.

Advancing Real-Time Imaging in Septal Myectomy

Traditionally, cardiothoracic surgeons use transesophageal echocardiography (TEE) before septal myectomy. However, TEE isn’t applicable during cardiac bypass surgery. Surgeons assess septal thickness with TEE before open-heart surgery and adjust the septum accordingly without real-time guidance. OPIE introduces a thin transducer into the heart during myectomy, enabling real-time visualization of septal thickness.

study featuring Fujifilm’s OPIE Transducer highlights that the system provides established imaging to aid in septal myectomy procedures compared to TEE and transthoracic echocardiogram (TTE). Real-time measurements of the interventricular septal thickness are crucial during septal myectomy to avoid creating a ventricular septal defect while resecting enough myocardium. The OPIE transducer is compatible with Fujifilm’s ultrasound system, the ARIETTA Precision. 

Advancing Septal Myectomy Procedures

“During septal myectomy, it is critical to correctly measure the patient’s septal thickness because it can directly impact the patient’s care pathway,” says Hideyuki Honda, Fujifilm’s vice president of ultrasound solutions.

“Every day we pride ourselves on delivering what we believe is the highest quality ultrasound solutions, arming cardiologists and cardiothoracic surgeons alike with the visualization they need to eliminate guess work in the operating room,” Honda adds. “Early clinical results of our OPIE Transducer during a high-risk procedure like cardiac bypass surgery are impressive, and we’re proud that the technology is proving to provide high-quality, real-time feedback for the surgeon.”
