Study: Procedures with Abbott’s Mitraclip show sustained low complication, mortality rates

February 5, 2019 By Fink Densford Leave a Comment

Despite an increase in the number of procedures due to aging patients, minimally invasive mitral valve repair procedures using Abbott‘s (NYSE:ABT) Mitraclip system maintain a low mortality and complication rate, according to a new study from Mainz University Medical Center’s Center for Cardiology.

Researchers in the Germany-based study examined more than 13,575 minimally invasive mitral valve procedures, touting the study as the largest of its kind to date.

“Several studies with small groups of patients have already been published for the evaluation of the procedure with regard to the frequency of inserting the clip or the safety of the procedure. However, there have been no large data collections so far. That’s why it was a good idea to examine the implantation numbers and the complication rates in Germany on a larger scale,” study authors said in a press release.

Results from the trial indicated that despite annual implantation numbers increasing from 815 in 2011 to 4,432 in 2015, complication and mortality rates “did not change significantly during the period studied,” researchers wrote in a press release.

Investigators concluded that despite an approximately fivefold increase in implantation rates, “the procedure has very low early-stage complications rates during hospitalization.”

“Catheter-assisted valvular heart valve therapy has evolved from a niche treatment of inoperable patients into a relevant and safe treatment option in only ten years, as our new study emphasizes once again,” study author Ralph Stephan von Bardeleben said in a prepared statement.

Abbott acquired MitraClip in the $410 million acquisition of Evalve back in 2009. The device, which is designed to reshape the mitral valve to prevent blood from flowing backwards through the valve, won its first FDA nod in 2013.

Last September, startlingly positive results from a clinical trial of theMitraClip heart valve device reportedly drew applause at the annual Transcatheter Cardiovascular Therapeutics meeting in San Diego.

Gottlieb wants to fix clinical trials before departing FDA
The FDA has issued new draft guidance to protect human subjects of clinical trials and the data these trials generate. The draft guidance on using a risk-based approach to conducting clinical trials is one of a handful of guidances promulgated by the agency since FDA commissioner Dr. Scott Gottlieb announced his upcoming departure. In a… […]
Toray touts polymer for regenerative medicine
Toray Industries (Tokyo) recently announced that it has created a novel bioabsorbable polymer with skin-like flexibility. Proprietary functional polymer design technology allows the polymer to recover its original shape even after being stretched 10 times the original length, the company explained in a March 14 announcement. Toray also has identified a way to improve the… […]
Thornhill Medical’s ‘simple’ device may save lives
Thornhill Medical’s device to help patients suffering from carbon monoxide poisoning has won de novo clearance from the FDA. Carbon monoxide poisoning occurs when carbon monoxide attaches to the hemoglobin in the blood exactly where oxygen is supposed to attach, reducing the amount of oxygen carried to the brain and other tissues. Toronto-based Thornhill Medical’s… […]

Study shows catheter ablation for Afib significantly boosts quality of life
Patients who had catheter ablation for atrial fibrillation (Afib) had fewer symptoms, a significant long-term improvement in quality of life and fewer recurrences and hospitalizations than those who received drug therapy alone, according to a government-funded study. The same study showed that catheter ablation appeared no more effective than drugs in preventing strokes, deaths, and… […]
Medical device cybersecurity: It’s time to get real
Medical device makers, regulators and healthcare delivery organizations are increasingly working together to strengthen cybersecurity. But are they doing enough? Almost no one in the medtech industry disputes the vulnerability posed by cyberattacks. How to go about boosting security is another matter – one on which those stakeholders have recently stepped up their collaboration. One… […]

FDA ramps up scrutiny of materials in medical devices
The FDA said today it has begun more closely scrutinizing the roles of certain materials associated with harm to patients who have breast implants, nitinol-containing devices, metal-on-metal hip implants and devices made from animal-derived substances. It’s the latest in a series of statements the agency has issued following increasingly harsh public criticism of its efforts… […]
