Adult Cardiothoracic Anesthesiology Fellowship

Welcome to the homepage of the Adult Cardiothoracic Anesthesiology (ACTA) Fellowship at New York-Presbyterian Hospital/Columbia University Irving Medical Center (NYPH/CUIMC). Established in 1991 and ACGME accredited since 2007, our fellowship welcomes nine fellows each year. We are the largest ACTA fellowship in New York, and our hospital is among the best cardiac centers in the region and in the world.

With over 2200 open heart cases performed per year and a busy thoracic service, our program provides fellows with the opportunity of a challenging, stimulating and rewarding experience, in the heart of one of most vibrant cities in the world.

Fellowship Overview

ACGME accredited
Program Start Date: July/August (flexible options for start dates)
Number of positions: 9
Duration of Training: 12 months

Clinical Experience

Our division provides the perioperative care of patients undergoing open heart valve and revascularization procedures, major thoracic and esophageal surgeries. In addition, fellows develop expertise in the management of patients undergoing adult congenital heart surgery, robotic-assisted CABG, major aortic surgery, minimally-invasive and transcatheter valve replacements, electrophysiology procedures, lung volume reduction surgery, pulmonary thromboendarterectomy, mechanical circulatory support device procedures, and heart and lung transplants.

Our fellows perform most of their cases as primary providers, with progressive autonomy throughout the year. To prepare them for independent and academic practice, fellows are given opportunities for supervision of junior residents.

Perioperative Transesophageal Echocardiography

With a 100% pass rate over the past decade, the program prepares our fellows for the National Board of Echocardiography (NBE) examination and certification requirements in advanced perioperative TEE. Our fellows are proficient in performing, interpreting and communicating a comprehensive intraoperative TEE examination to optimize the perioperative care of patients undergoing complex cardiac, adult congenital, and thoracic surgery. This is accomplished by a combination of didactic teaching, hands-on intraoperative experience, as well as simulation-based practice in our state-of-art simulation center.

Didactic Curriculum

Our education program combines the benefits of both experiential, hands-on learning and formal didactic education. Our dedicated curriculum combines lecture series, problem-based discussions, journal clubs and case reviews, given by faculty from multiple disciplines.

Research Opportunities

The Department of Anesthesiology supports the research productivity of our fellows, which is aligned with the department’s mission. Whether it's echo rounds, case reports, medically challenging cases, abstract and poster presentations, book chapters or peer reviewed articles, our fellows develop and disseminate knowledge relevant to our specialty by attending and participating in regional and national meetings. Fellows in ACTA who are interested in exploring specific research opportunities can choose to participate in one of the ongoing clinical, TEE, and education research projects. They can also choose to develop their own research proposal, with the guidance of a faculty mentor. All our fellows participate in patient safety quality improvement projects relevant to the practice of adult cardiothoracic anesthesia.


In addition to textbooks and a subscription to online TEE learning modules, ACTA fellows are provided an educational stipend to be used at their discretion.  Furthermore, our fellows are given the time and financial support needed to participate in regional or national conferences.

Dual ACTA/Anesthesiology Critical Care Medicine 2-Year Fellowship

The dual ACCM/ACTA fellowship track consists of two consecutive years of training and is offered to 2-3 applicants each year. Per ACGME, these are two separate one-year fellowships. Applicants interested in pursuing both fellowships at our institution should apply first to the ACCM fellowship via the SF Match and indicate their interest in a dual fellowship. Exceptions for the dual ACCM/ACTA fellowship are offered outside the match. Applicants who are not offered an exception but who are still being considered for an ACCM fellowship position only will participate in the SF Match.   Those applicants may reapply to ACTA the following year.  

Both programs must be informed of your intent to pursue the dual fellowship track. Notification should be sent to both Lisa Hasenbalg and Clara Gutierrez.
