1,000 Magmaris Implantations Reveal High Deployment Success and Physician Satisfaction

BIOTRONIK’s Magnesium 1,000 program has provided physicians an early post-market opportunity to evaluate the new resorbable Magmaris magnesium scaffold outside of clinical trials. Physicians reported very positive experiences, with 98.8% of scaffolds successfully deployed and highly positive ratings for the acute performance of the Magmaris scaffold compared to the leading polymeric scaffold.

The Magnesium 1,000 program began on June 15, 2016, reaching 1,000 implants on 24 February, 2017, and included 413 physicians in 237 hospitals across 32 countries. Physicians were asked to rate their personal experiences of acute performance with Magmaris, but also to compare their experiences with the leading polymeric scaffold for each case using an evaluation form.

Roughly 96% of program participants rated the overall performance of Magmaris as either good or very good, with similar results in the individual categories, including trackability, pushability, crossability and conformability among others. In 72.1% of cases, the Magmaris scaffold was tested against the leading polymeric scaffold as a benchmark to evaluate product performance. Magmaris was rated in 70-78% of cases as better or slightly better in various categories of acute performance, such as deliverability and vessel conformability.

“The scaffold’s exceptional trackability and crossability help to facilitate smoother delivery,” said Dr. Gregor Leibundgut, Kantonsspital Baselland, Liestal, Switzerland. “This makes the implantation easier and safer for the doctor and the patient.” Because of the scaffold’s unique design, its backbone is more flexible than that of the leading competitor, allowing good vessel conformability. In addition, the scaffold features an electro-polished metallic surface, offering smoothness and rounded edges to enable lower friction and easier lesion crossing.

The goal of the Magnesium 1,000 program was not only to gather information on the product’s acute performance, but also to help first implanters gain experiences in the most effective possible use of Magmaris. “With the Magnesium 1,000 program, we wanted to ensure that physicians could achieve the best possible results with Magmaris,” said Dr. Alexander Uhl, BIOTRONIK Vice President Marketing, Vascular Intervention. “This means providing physicians with a clear protocol for implantation.” Through the Magnesium 1,000 program, physicians were directed on how to properly use the Magmaris scaffold and advised to focus on the “4 Ps”: patient selection, proper sizing, pre-dilatation and post-dilatation. Magmaris is currently indicated for patients with de novo lesions that closely match the available scaffold sizes.
