STS CEO and Executive Director Elaine Weiss, JD, has announced plans to retire. Weiss joined the Society of Thoracic Surgeons in 2019. 

“Ms. Weiss has been a superb leader for STS, collaborating closely with surgeon leaders to advance the Society on multiple fronts over the past seven years,” STS President Vinay Badhwar said. “We have deeply valued her strategic contributions and management oversight.”

Badhwar added, “As the premier organization in the specialty, STS looks forward to identifying our next CEO to continue Ms. Weiss’s legacy as we build upon our innovation, operational excellence, and global impact.”

The STS has selected Immediate Past President Dr. Joseph Sabik, to lead the search committee. Additional search committee members are Drs. Vinay Badhwar, Vinod Thourani, Jessica Donington, Wilson Szeto, Jenna Romano, John Mitchell, David Cooke, Adil Husain, and Susan Moffatt-Bruce.

STS has retained Spencer Stuart to assist in the search.

The Society of Thoracic Surgeons today announced Thomas E. MacGillivray, MD, as the recipient of the 2026 Distinguished Service Award in recognition of his extraordinary dedication to the field of cardiothoracic surgery and his longstanding service to STS at the Society’s 62nd Annual Meeting in New Orleans

Dr. MacGillivray is Physician Executive Director of Cardiac Surgery at MedStar Health and Chairman of Cardiac Surgery at MedStar Washington Hospital Center. He previously held senior leadership roles at Houston Methodist Hospital, including the Jimmy F. Howell, MD, Endowed Chair in Cardiovascular Surgery, Chief of Cardiac Surgery and Thoracic Transplant Surgery, and Associate Medical Director of the Cardiovascular ICU. Earlier, he spent 19 years at Massachusetts General Hospital as Surgical Director of the Adult Congenital Heart Disease Program, Co-Director of the Thoracic Aortic Center, and Surgical Director of the Mechanical Circulatory Support Program, while also serving as Associate Professor of Surgery at Harvard Medical School.

Across each of these leadership roles, Dr. MacGillivray has demonstrated an unwavering commitment to clinical excellence, innovation, and mentorship.

“Dr. Thomas MacGillivray embodies the highest standards of leadership, innovation, and dedication to the field of cardiothoracic surgery,” said STS President Joseph F. Sabik III, MD. “His unwavering commitment to advancing thoracic care and mentoring the next generation of surgeons has left an indelible mark on our Society and the specialty as a whole.”

Dr. MacGillivray is a board-certified cardiac and thoracic surgeon with more than 30 years of experience in both traditional open and minimally invasive techniques. His expertise spans coronary artery bypass, valve repair and replacement, thoracic aortic surgery, maze procedures, septal myectomy, cardiac tumor surgery, and adult congenital heart disease. He is committed to patient-centered care, following patients through their entire surgical journey from the OR to recovery.

His clinical and academic interests include aortic disease, adult congenital heart disease, heart failure, and pulmonary embolism. A strong advocate for quality improvement, he focuses on outcomes research and large clinical databases. He has authored more than 125 peer-reviewed articles and textbook chapters on aortic disease, adult congenital heart disease, mechanical circulatory support, and cardiac tumors.

Dr. MacGillivray earned his medical degree from Tufts University School of Medicine after completing undergraduate studies in Classical Studies at Tufts University. He completed his internship and general surgery residency at Massachusetts General Hospital, followed by an extensive and distinguished fellowship training pathway that included a research fellowship in fetal surgery at the University of California, San Francisco; congenital heart surgery training as Chief Resident at Boston Children’s Hospital; and adult cardiothoracic surgery training as Chief Resident at Massachusetts General Hospital.

Through decades of clinical excellence, academic contribution, and service-oriented leadership, Dr. MacGillivray has made a lasting impact on cardiothoracic surgery. The 2026 Distinguished Service Award recognizes not only his remarkable career, but also his enduring commitment to patients, colleagues, and the future of the specialty.

On Sunday, Feb. 1 at 10:45 a.m., during the “Advancing Lung Cancer Screening Implementation in Real World Settings” session, Dr. Elliot Servais of Lahey Hospital and Medical Center will present The Society of Thoracic Surgeons Expert Consensus on Surgical Quality Standards for Lung Cancer Screening Detected Nodules. As chair of the STS Task Force responsible for the consensus document, Dr. Servais will walk attendees through comprehensive, multidisciplinary recommendations designed to standardize perioperative care for CT lung cancer screening programs nationwide.

Lung cancer screening with low-dose CT has proven effective in reducing disease-specific mortality, but wide variation in how programs manage screen-detected nodules persists. To address this, the STS convened a multidisciplinary panel to review the evidence and establish clear benchmarks for diagnostic evaluation, complication rates, and timeliness of intervention. Through a structured literature review and modified Delphi process, the panel produced 23 consensus statements focused on improving safety, consistency, and coordination in screening pathways.

Key recommendations include permitting surgery without a preoperative tissue diagnosis in select patients—preferably using minimally invasive, parenchymal-sparing techniques—and rejecting pneumonectomy without a diagnosis.

In his presentation, Dr. Servais will also highlight why certain targets, such as achieving a benign resection rate below 10%, may challenge some programs. “Meeting this benchmark requires consistent multidisciplinary review, judicious use of preoperative biopsy, and a willingness to follow equivocal lesions closely—approaches that can reduce unnecessary surgery and improve patient outcomes,” says Dr. Servais.

By integrating diverse clinical perspectives, programs can better determine when invasive intervention is warranted versus when surveillance is safest, improving decision-making and minimizing avoidable procedures.

“Thoracic surgeons must remain central to lung cancer screening programs, and adherence to strong perioperative quality standards—rooted in multidisciplinary evaluation, operative safety, and timely intervention—is critical to ensuring that lung cancer screening continues to save lives with minimal harm to patients,” adds Dr. Servais.
