By establishing the Structural and Congenital Heart Center, Hackensack has created an opportunity to differentiate its cardiology services and position itself as a destination for leading-edge structural heart disease treatment.
Philips has partnered with Hackensack to build a hybrid OR that is key to the growth of the structural heart disease (SHD) center of excellence. In this article, Hackensack’s lead interventional cardiologist and echocardiographer share their experience with Philips integrated solutions in the lab and their outlook on what’s to come in the future of SHD treatment.
Customer story at-a-glance
The trends that are shaping structural heart care today
With more patients of younger age and lower risk getting referred for structural heart procedures, minimally invasive procedures offer important benefits, such as faster recovery time and less use of anesthesia. Dr. Lucy Safi, Interventional Echocardiography, notes a greater variety of procedures are being performed, including more mitral and tricuspid valve interventions, driven by the fact that clinicians are able perform more interventions percutaneously. The Structural and Congenital Heart Center at Hackensack is involved in several key clinical trials that will shape the future of SHD. There is a tremendous amount of innovation in the field around new technologies and devices, and one of the keys to successfully bringing this innovation to patients lies in equipping operators with the support they need to handle new devices and techniques safely and confidently.
"Imaging, like Philips is doing, is a big component of how safely operators can deploy these new technologies."
Dr. Tilak Pasala Interim Director, Structural and Congenital Heart Center Program
A closer look at the care pathway
Structural heart procedures deal with complex anatomical structures that must be clearly visualized to help clinicians confidently diagnose and treat each patient.
From the moment a patient is assessed for structural heart disease, the care team must work together to ensure the patient receives the right diagnosis and the appropriate treatment. Accurate diagnostic images, clear image guidance, seamless communication and efficient workflows are essential—and the Philips suite of cardiology solutions is purposefully designed to deliver this confidence and efficiency at each point on the patient journey.

Diagnosis and planning
As a large referral center, many of Hackensack’s challenges lie in the evaluation of pre-procedural imaging—making sure that each patient receives the appropriate exams and that the images are of diagnostic quality so that the patient can be moved quickly and confidently into treatment.
Dr. Safi states, “As an imager, my job is to evaluate all the images and pre-procedural tests that a patient has. Having the right workup and good quality images is necessary, so the patient gets an overall accurate diagnosis.”
Dr. Safi also notes that Hackensack has observed an increase in the number of mitral valve procedures, which bring challenges in assessment and modification due to the complexity of the valve’s saddle-shaped anatomy and its tendency to calcify.
Properly sizing and evaluating the function of the valve is a time-consuming process, but Dr. Safi has found the Philips EPIQ ultrasound system to provide excellent 3D imaging, with built-in automation that provides fast, easily reproducible results that are less dependent on the operator’s level of experience. Tools such as 3D AutoMV quantify the function, key structures and size of the mitral valve anatomy to help Dr. Safi and her team quickly and accurately assess each patient and identify the right path to treatment.
Other tools such as Cardiac TrueVue provide new ways to further visualize the mitral valve’s function and anatomy.
Key features of the Philips EPIQ cardiovascular ultrasound system
Enables accurate representation and Doppler quantification of the target flow without losing the correct image alignment.
MultiVue real-time alignment
Allows one-click cropping of a Live 3D image during interventional procedures, and one-click alignment of the catheter within cardiac anatomy.
EchoNavigator cardiac fusion imaging
Uses SmartFusion to fuse live TEE and live fluoroscopic images in real time. TEE transducer position and orientation are automatically tracked in the X-ray image, allowing the echo and X-ray images to move in sync when the C-arm is repositioned.
Cardiac TrueVue Color with Glass
Appreciate the structure of cardiac anatomy and cardiac flow through real-time rendering with a movable light source that can be applied in both echo and color images. Cardiac TrueVue Glass can also enable a cast-like rendering of any 3D structure.
3D Auto LAA for LAA sizings
Acquire the LAA ostium size quickly and easily, using automation that reduces inter- or intra-user variability and increases confidence during procedures.
3D Auto MV for mitral valve quantification
Analyze the complex anatomy of the mitral valve in 3D as well as its dynamic mechanics. Geometric measurements such as annular dimensions, leaflet, morphology and coaptation descriptions can be used from the initial discovery of MV disease or pathology to support device planning, and through monitoring of pre- and postoperative cases.
Access and navigation
Once a patient is diagnosed and moved into treatment, a new set of challenges arises related to ensuring the room is set up correctly and the clinical team has access to the tools and information they need for a successful procedure.
"The Azurion system gives us flexibility in setting up the lab ahead of time. Once we’ve done that, we’re able to function very fluidly and seamlessly, and we find it very useful that it can work around where we are standing."
Dr. Tilak Pasala Interim Director, Structural and Congenital Heart Center Program
The Azurion FlexArm interventional from Philips is designed for flexibility and efficiency:
Intra-procedural assessment and treatment
During the procedure, the interventionalist and imager must work together seamlessly to navigate and deploy the device at the right location. This process relies on the imager using ultrasound to move back and forth between multiple imaging modes—and between 2D and 3D images—to accurately determine device placement.
Both Dr. Pasala and Dr. Safi have seen the value of EPIQ’s multiplanar reconstruction in driving both confidence and efficiency during the procedure.
“If we are able to see the device well on the image, it gives the operators a feeling of confidence and safety,” says Dr. Pasala.
And Dr. Safi observes, “As a proceduralist, when you have literally seconds to get the image and give an answer, you want the best technology there to help you. Multiview multiplanar reconstruction helps you get the right image quickly.”
Both Dr. Pasala and Dr. Safi have found fusion imaging to be a critically important diagnostic and therapeutic tool in structural heart procedures. Dr. Pasala states, “Where we’re seeing the most advantage is to actually marry everything together into one image – where catheters are well seen on fluoroscopy, where there is a three-dimensional understanding of anatomy, so you’re putting everything together for operators…Now they have all the information they need in procedures.”

Both echocardiography and fluoroscopy are essential to interventional imaging—echocardiography visualizes soft tissue, while fluoroscopy visualizes devices. But the two modalities are acquired and displayed in different orientations, which can make understanding and communication difficult during the procedure.
With Philips EchoNavigator, echocardiography and fluoroscopy images display in the same orientation, helping to improve understanding and communication between imager and interventionalist. EchoNavigator allows visualization of both live echocardiograpy and live fluoroscopy images, to provide accurate views of both soft tissue and devices—and markers placed on echo can appear in fluoro to allow precise guidance.
Azurion FlexVision Pro with touchscreen module Pro provides intuitive, seamless control of all available applications at tableside.
EPIQ CVxi with EchoNavigator provides a streamlined workflow experience for live fusion imaging.
"Echo fusion has really helped reduce procedural time and reduce radiation that the patient receives. In these advanced cardiac procedures, we want to make sure we limit the time patients are under anesthesia, limit the radiation they get – it’s always better for patient outcomes.”
Dr. Lucy Safi Director of Interventional Echocardiography
Post-procedural assessment
After a device is placed, clinical teams require high-quality imaging and efficient workflows to assess the completeness of treatment and document results. Tools like TrueVue and GlassVue help the echocardiographer visualize any residual leakage and confirm that functional results are as expected.
Dr. Safi states, “TrueVue is very helpful in patients with prosthetic valve replacements. When we use TrueVue, we’re able to move the light source and really take a full look at the prosthesis. If the patient has a perivalvular leak, we can really see where that leak is by moving the light source.“
Cardiac TrueVue Glass is really helpful for multiple things. When we’re doing MitraClip procedures or assessing a mitral valve, we’re able to change the density of the tissure to see exactly where the regurgitation is coming from. It saves so much time. When doing LAAO devices, we can make tissue translucent to see the ostium of the left atrial appendage very clearly.”
Cardiac TrueVue Glass allows users to see complete color flow without losing anatomical context.
For interventionalists like Dr. Pasala, an efficient workflow is essential to help assess hemodynamic function and document the results in the clinical documentation system. Azurion’s touchscreen module allows Dr. Pasala to confirm hemodynamic function using the Philips HemoSystem while automatically documenting results on XperIM reporting software—directly from the tableside.
Shaping the future of structural heart disease treatment
As Dr. Pasala and Dr. Safi consider the future of structural heart disease treatment, they are excited by the tremendous pace of innovation that is happening in the space. Hackensack is on the leading edge of this innovation. It’s currently one of three sites enrolled in a clinical trial for a new tricuspid an nuloplasty device.
Hackensack is also a leader in transcatheter mitral valve replacement, and the center is involved in two heartfailure/structural heart collaborative studies. All these studies are very imaging intensive, and one of the advantages of Hackensack as a trial site is that the center offers advanced imaging capabilities, including fusion imaging from Philips.
As Dr. Pasala considers the future of structural heart disease treatment and how these new innovations can change patient care, he notes, “I think there is value being able to partner and standardize some of the procedural steps from an imaging perspective. Echo fusion and CT fusion are game changers in terms of operator confidence and safety for these new procedures.”
Conclusion
As Hackensack continues to grow its Structural Heart center of excellence, its clinicians have recognized the value of partnership with Philips in helping them deliver optimal outcomes with efficiency.
