Successfully placing the left ventricular (LV) lead in an optimal clinical location is a recognized challenge of cardiac resynchronization therapy (CRT). And although the rate of failure to place the LV lead in patients has decreased over time, there is always room for improvement. This is where Interventional CRT (I-CRT) comes in. “I-CRT…forces the operator […]
Patients suffering from atrial fibrillation (AF) have a minimally-invasive curative treatment option thanks to advancements in cardiac ablation catheter technology. The use of one such advancement, the steerable sheath, has resulted in higher clinical success rates in comparison to using a traditional fixed sheath.1 But despite its clinical success, operating the steerable sheath has its challenges, such as knowing a sheath’s position when under fluoroscopy.
In an effort to anticipate clinicians’ needs, Merit Medical has designed a procedural solution called the HeartSpan® Steerable Sheath. It allows a clinician to move the distal tip from 0° and 180° to achieve the desired curve within the atrial chamber. Unlike any other steerable sheath on the market, the HeartSpan facilitates catheter navigation by offering a Neutral Position Indicator and a tactile click at the neutral position. For ease of use, its ergonomic handle displays two arrows that indicate the directional plane of the curve as the handle turns.
Reaching the desired catheter position by way of a steerable sheath has been shown to have several benefits. A randomized controlled study by Piorkowski et al. investigated the clinical outcomes of using a steerable sheath in comparison to a fixed sheath.1 The study prospectively included 130 patients with paroxysmal or persistent drug-refractory AF undergoing interventional cardiac ablation for the first time.
Results published in Circulation Arrhythmia and Electrophysiology showed that single procedure success was significantly higher in patients ablated with a steerable sheath (78% vs. 55% after 3 months; 76% vs. 53% after 6 months).1 Additionally, fluoroscopy time was lower in the steerable sheath group (33+/-14min vs. 45+/-17min). The authors concluded that using a steerable sheath improved catheter stability and catheter-to-tissue contact when compared to the traditional fixed sheath.
In addition to the Neutral Position Indicator, the HeartSpan has other state-of-the-art features that support procedural success. For navigating anatomical variations, the HeartSpan is available in three curl sizes. Its braided construction offers kink resistance and curve durability. A lower crossing profile enables seamless dilator to sheath transition for smooth advancement across the atrial septum. Radiopaque marker bands enhance visibility, and an atraumatic tip reduces the risk of atrial wall perforation. The HeartSpan’s shaft body is smooth and lubricious for easy vessel insertion.

At Merit Medical, we’re dedicated to using the most advanced materials, designs, and manufacturing techniques with the goal of delivering solutions you can always depend on. Our PreludeEASE™ Hydrophilic Sheath Introducer is a perfect example of this commitment. Designed for strength, data shows the PreludeEASE resists compression better than the leading competitor—making it the New Go-To sheath.1
Compression resistance is an essential factor when considering a new sheath. Case studies have shown that if an arterial spasm occurs during a procedure, it can lead to the sheath compressing into the catheter, entrapping it within the vessel, and making removal of the catheter from the sheath difficult.2
Some thin-walled sheaths can be prone to compression and kinking that could result in difficult catheter manipulation. In the event of radial spasm, the catheter and sheath may need to be removed. Using a product with robust sheath tubing, like the PreludeEASE, may help clinicians avoid this problem. When tested against the leading competitor, the PreludeEASE displayed excellent compression-resistance performance.1
Other PreludeEASE advanced features include a large inner diameter for easier transitions and increased device compatibility and hydrophilic coating to facilitate insertion and removal as well as patient comfort.3 Moving smoothly from wire to dilator and dilator to sheath, the PreludeEASE streamlined design requires up to 30% less insertion force in comparison to the leading competitor.1
To accommodate varying patient anatomy, the PreludeEASE is available in multiple size configurations that range from 4F-7F diameters and can be customized in kits and packs to include other tools you need to achieve radial success.

Merit Medical is committed to the radial approach, with a comprehensive portfolio of radial products supporting radial procedures from set-up and access through hemostasis, as well as the ThinkRadial training program for Interventional Cardiologists and Radiologists. And in this year, the 25th anniversary of radial access, we are happy to spotlight some of our key radial products, starting with the sheath used to gain access to the radial artery.
The has evolved to address the needs of radial interventionalists. The smooth transitions between wire to dilator, and dilator to sheath, have been fine tuned for patient comfort, resulting in up to 30% less insertion force, as compared to the leading competitor1. The hydrophilic coating further facilitates insertion and removal as well as patient comfort.2
Studies also show that the hydrophilic coating on sheath introducers can reduce the incidence of artery spasm and improve patient comfort during transradial diagnostic and interventional coronary procedures.3
The PreludeEASE™ maintains a robust design that resists kinking while still providing a large inner diameter for increased device compatibility. Combining a slim profile and a large inner diameter, the PreludeEASE provides optimal dimensions without compromising integrity or performance.
On May 31, 2017, Dr. Ferdinand Kiemeneij, “@ferdikiem”, tweeted about the PreludeEASE:

Merit Medical will be hosting the next ThinkRadial Education Course on October 13-14 for Interventional Cardiologists and Radiologists. Physicians are already looking forward to this course and the opportunity to learn from the “Father of Transradial Intervention,” Dr. Ferdinand Kiemeneij. Merit is honored to once again have Dr. Kiemeneij proctor this course, to share his extensive knowledge and experience, as he did in the April ThinkRadial Course. This course will be held at the Merit Medical Global headquarters in Salt Lake City, UT on Friday, October 13 and Saturday, October 14, 2017.
Interventional Cardiologists who currently practice the transradial access technique, who want to advance their skills for more complex interventional procedures, will be proctored by Dr. Sandeep Nathan (University of Chicago) as well as Dr. Ferdinand Kiemeneij. Interventional Cardiologists attending the course will present their own complex cases for discussion and troubleshooting as well as observe complex taped cases. These physicians will learn how to navigate potential complications and increase their use of transradial for complex interventions.
Interventional Radiologists who are new to the radial approach as well as those who want to increase their knowledge and skill will be proctored by Dr. Darren Klass (Vancouver General and UBC Hospitals). Interventional Radiologists will be taught the data and economics supporting transradial access, learn about patient selection, room set-up, and equipment selection. They will learn and practice access and hemostasis techniques and discuss how to navigate potential complications. Both groups will have the opportunity to practice the radial technique on cadavers.
Dr. Kiemeneij performed the first transradial coronary angioplasty in 1992, followed by transradial stenting in the same year and stenting on an outpatient basis in 1994.
Dr. Klass is an expert in transradial radioembolization and is developing a robust hardware platform for radial access to the liver. His practice is 90% radial for liver interventions and fibroid embolization.
Dr. Nathan describes his mindset as “radial first” and utilizes the transradial approach in more than 75% of his coronary cases. He believes that transradial “is a golden opportunity to improve patient comfort and safety, without compromising procedural efficacy.”
The October ThinkRadial Course is a full day and a half of didactic presentations, taped cases and hands-on training opportunities, complimented by a group dinner and presentation by the guest of honor, Dr. Ferdinand Kiemeneij.
