Training and Experience Count: Myectomy is Safest at High-Volume Centers
Myectomies at hospitals averaging more than 10 procedures per year led to fewer deaths and complications than at other hospitals.

Large study of US myectomies

Myectomy is safest at high-volume centers. A study accepted in The Annals of Thoracic Surgery provides new evidence of this.

Kimberly A. Holst and her collaborators (2022) examined nearly 6,000 US myectomies reported from 2012 to 2019. Their data came from a database compiled by the Society of Thoracic Surgeons.

Mortality and post-operative risks lowest in high-volume centers

The researchers found that the chance of death was lowest in hospitals that performed more of the surgeries. But they also found that the risk of serious complications was much lower in these hospitals. The complications they studied included perforation of the interventricular septum and complete heart block.

Furthermore, those high-volume hospitals replaced mitral valves less often as part of the procedure.

Myectomy is safest in high-volume centers

These results strengthen the conclusions suggested by Kim et al. (2016) , that septal myectomy is safest at high-volume centers.

It is hard to believe the first quarter of 2025 is in the history books. In the space of hypertrophic cardiomyopathy and thick heart muscle disorders, the distance between the promise and the delivery of a reality freed from burden of disease is closer than it has ever been, not only in the United States but throughout the world. Unfortunately, we are navigating through some challenging health policy times, which will impact a large percentage of those with the diseases we seek to serve. While we navigate these challenging waters together, we remain committed to ensuring safe, accessible, affordable, healthcare while ensuring the rights of those with disabilities are maintained. Last month, I attended two large conferences - one held in Stockholm, Sweden the other Chicago, Illinois. The research communities worldwide are holding their breath, waiting to see how we will move forward, even as we continue to develop new therapies, treatments and, even potentially, cures. It has never been more important to keep research moving, as we are so close to so many amazing improvements in our ability to care for those with thick heart muscle disorders, including HCM in all its forms, Amyloidosis, Fabry’s disease, Danon disease, and RASopathies. There was amazing science presented at the American College of Cardiology, where we warmly welcomed new president, Dr Christopher Kramer, the original director of the hypertrophic cardiomyopathy center at University of Virginia. We look forward to his leadership and wish him well in his challenging tasks ahead. Later this month we will be in Orlando Florida - please register and join us for this wonderful Bighearted warrior tour in person with our friends at AdventHealth and the incomparable Dr. Marcos Hazday. I even understand that there's some carpooling being organized from the Tampa area. If you're interested, reach out to the office and we will connect you. Maybe, the most impactful thing that will happen in the month of April is that we will conduct our second visit to Capitol Hill. Our lead topic this year is something you have heard us talk about at many prior meetings of the HCMA and podcasts; the generic drug quality issue. We are proud to be partnering with David Light, Co-founder and President of Valisure, and retired Colonel Vic Suarez, to ask House and Senate members to support the inspection of all generic drugs purchased by the Department of Defense and the Veterans Administration and make results of these inspections open for public use. Secondly, we are seeking rational oversight of health insurance companies’ abuse of prior authorizations and step therapy requirements. These issues cost an estimated 1.3 billion dollars a year and provide nothing to keep a patient safer or a physician's office running more efficiently. Common sense tells us to not waste money where there is no return. Additionally, prior authorizations and step therapies can keep patients sicker longer, ultimately costing the healthcare system more money. Our briefing will educate Representatives to act in an informed manner when moving policies that impact us all. You can watch us live at our briefing Wednesday April 9th 5:00 to 7:00 p.m. on Vimeo: https://vimeo.com/event/5043266 If you wish to get involved or more informed on any of the issues above, I encourage you to visit the website, 4hcm.org , or reach out to the office and the staff will be happy to assist you. On the day before I head out to Washington DC, I will leave you with this one thought - we have come a really long way in our understanding of HCM over the past 60 years. We have increased the lifespan of those with HCM, through collaborative research and implementation of best practices in an organized fashion throughout this country. We have worked so hard to end suffering for so many, and we are succeeding in our shared goal to outsmart hypertrophic cardiomyopathy and other thick heart muscle disorders. It is important to continue the research into all aspects of these diseases, including the biological, the clinical, burden of disease measurements. System improvements, positive impact of timely diagnosis and treatment, and the value to society of all of these big hearts being here, keeping their families whole. So we're off to DC to try to educate others about what it really means to live in our ecosystem. Best wishes, Lisa
