A Better Way Forward: Seth Worley, MD, Writes About the Benefits of Adopting I-CRT in June 2018 EP Lab Digest
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 […]

Know Your Direction: Merit’s HeartSpan® Steerable Sheath Facilitates Catheter Navigation
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.

The New Go-To: PreludeEASE™ Resists Compression Better Than the Leading Competitor
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.
