The Society of Thoracic Surgeons (STS)—a global leader in cardiothoracic surgery quality, research, and advocacy—has announced a significant leadership transition. Effective August 31, 2026, Justine Varieur Turco will assume the roles of Chief Executive Officer and Executive Director. Turco, a veteran executive with a robust background in medical publishing, clinical guidelines, and professional association leadership, will succeed the outgoing CEO, Elaine Weiss, who is stepping down after a distinguished seven-year tenure.
This transition marks a pivotal moment for the organization as it navigates a rapidly shifting landscape defined by technological innovation, evolving healthcare policies, and the increasing demand for data-driven surgical outcomes.
The Core Transition: A Strategic Handover
The appointment of Justine Varieur Turco follows an extensive, nationwide executive search conducted by the STS Board of Directors. The goal of this search was to identify a leader capable of maintaining the organization’s long-standing commitment to surgical excellence while steering it through the complexities of the mid-2020s healthcare environment.
Turco arrives at the STS following a highly successful tenure at the American College of Cardiology (ACC), where she served as the Vice President of Scientific Publications and Guidelines. Her work at the ACC—specifically her oversight of the Journal of the American College of Cardiology (JACC) portfolio and the joint ACC/American Heart Association (AHA) clinical practice guidelines—is widely regarded as having set a gold standard for disseminating evidence-based medical information.
The departure of Elaine Weiss marks the end of an era for the Society. Weiss, who boasts over 40 years of experience in association management, has been credited with stabilizing the organization’s fiscal health, expanding its global footprint, and cementing the STS National Database as the premier clinical registry in the specialty.
A Chronology of Leadership and Organizational Evolution
To understand the weight of this appointment, one must look at the historical trajectory of the Society of Thoracic Surgeons and the professional background of its new leader.
The Weiss Era (2019–2026)
When Elaine Weiss took the helm in 2019, the STS faced the dual challenge of navigating traditional professional membership pressures and the rising costs of medical data management. Over the last seven years, Weiss focused on:
- Digital Transformation: Modernizing the Society’s educational platforms to reach a global cohort of surgeons.
- Advocacy: Expanding the Society’s influence in Washington, D.C., regarding reimbursement policies and patient safety standards.
- Resilience: Successfully guiding the organization through the logistical and financial uncertainties posed by the global pandemic.
The Turco Foundation: Two Decades of Expertise
Justine Varieur Turco’s career path has been defined by a consistent focus on the intersection of medical science and operational efficiency. Her professional journey includes:
- Early Career (Boston Children’s Hospital): Turco cut her teeth in the complex environment of a leading pediatric medical center, gaining an intimate understanding of the operational realities of surgical departments.
- The ACC Years: During her time at the American College of Cardiology, Turco played a pivotal role in bridging the gap between clinical research and real-world application. By managing complex partnerships and overseeing high-impact publications, she developed a reputation for being a "builder of ecosystems"—a skill set the STS Board specifically sought to leverage.
Supporting Data: Why the STS Remains a Global Standard
The Society of Thoracic Surgeons is not merely a professional membership group; it is an institution that provides the infrastructure for modern heart and lung surgery. The importance of the CEO role is underscored by the scope of the organization’s assets:
- The STS National Database: Arguably the most comprehensive surgical registry in the world. It contains millions of patient records that inform quality improvement initiatives globally. The incoming CEO must manage the continued integration of AI and machine learning into this database to provide real-time feedback to surgeons.
- Scientific Impact: Through its flagship publications, such as The Annals of Thoracic Surgery, the STS is the primary venue for clinical trial results that define the standard of care for cardiovascular and thoracic pathologies.
- Educational Outreach: The Society’s annual meetings and specialized training modules are essential for the certification and ongoing education of thousands of surgeons. Turco’s background in education and publishing will be instrumental in expanding these digital-first offerings.
Official Responses: The Vision for the Future
The transition has been met with broad support from the STS Board and the broader surgical community.
"The Board is extremely confident that her experience and bold leadership will help build on STS’s strong foundation and advance the Society’s global mission in support of cardiothoracic surgeons and the patients they serve," said Vinay Badhwar, MD, STS President. Dr. Badhwar emphasized that the board was looking for someone who could balance the technical demands of surgical registry management with the human-centric needs of a professional membership organization.
In her first official statement as the incoming CEO, Turco acknowledged the gravity of the position:
"Healthcare is at an important inflection point, shaped by evolving policy, technology, and care delivery models. STS has long been a leader in advancing quality, education, research, and data-driven improvement in cardiothoracic surgery. I am honored to join the Society and look forward to working with its members, Board, and staff to build on that legacy and support the specialty’s continued advancement."
Implications: The Road Ahead for the Specialty
As Justine Varieur Turco prepares to step into her role on August 31, 2026, the strategic priorities for the STS are clear. Her tenure will likely focus on four key pillars:
1. Technological Integration
The field of cardiothoracic surgery is currently undergoing a revolution in robotics, minimally invasive techniques, and transcatheter procedures. Turco will be tasked with ensuring that the STS remains the primary repository of data regarding the long-term outcomes of these new technologies, ensuring that "innovation" is synonymous with "patient safety."
2. Navigating Economic Pressures
Healthcare economics are becoming increasingly complex. From changes in CMS (Centers for Medicare & Medicaid Services) reimbursement models to the rising costs of surgical technology, the STS must continue to serve as a powerful advocate for its members. Turco’s experience in navigating the policy corridors of the ACC will be a significant asset in this regard.
3. Strengthening Global Partnerships
While the STS is an American institution, its standards are the benchmark for cardiothoracic surgery worldwide. Turco is expected to look for opportunities to harmonize surgical standards across international borders, facilitating a more globalized exchange of best practices.
4. Sustaining the Workforce
The "surgical burnout" crisis is a reality in medical fields across the board. The STS, under Turco’s leadership, will likely look to expand its initiatives regarding physician wellness, mentorship for early-career surgeons, and the promotion of diversity within the surgical specialty.
Conclusion: A Seamless Transition
The appointment of Justine Varieur Turco is characterized by a thoughtful, well-planned transition. By announcing the appointment more than a year in advance, the STS has ensured a period of continuity, allowing for a structured handoff from Elaine Weiss.
As the surgical community looks toward 2026, there is a clear sense of optimism. The Society of Thoracic Surgeons, an organization that has historically been defined by its commitment to clinical precision and scientific integrity, appears to have found a leader who embodies these values. With a proven track record of managing complex medical organizations and a forward-looking perspective on the role of data in clinical care, Turco is well-positioned to guide the STS through the next decade of medical advancement.
For the surgeons who rely on the STS for their clinical registry data, and for the patients who benefit from the high standards set by the Society, this transition marks not just a change in management, but a renewal of the mission to save lives through surgical excellence. As the healthcare landscape continues to evolve, the STS stands ready to meet the future, anchored by its rich history and guided by a new, seasoned hand.
