Cardiothoracic Anesthesiology Fellowship

Welcome to the Adult Cardiothoracic Anesthesiology Fellowship

Shanna Hill, MD

It is my pleasure to welcome you to the cardiothoracic fellowship at Weill Cornell Medicine. Our program was first established in 1989 and has been accredited since 2007, one year after the ACGME awarded accreditation to cardiothoracic fellowships nationwide. Over the last 30 years, our program has produced numerous graduates that are amongst the leaders in the specialty of Cardiothoracic Anesthesiology today.

Our mission is to train world-class, versatile cardiothoracic anesthesiologists who are experts in perioperative medicine and echocardiography. Our fellows receive a comprehensive and rigorous curriculum rich with a broad variety of clinical and educational experiences that primes them for excellence in both academic and non-academic settings, as well as success in certification through the National Board of Echocardiography in Advanced Perioperative Transesophageal Echocardiography (PTE).

Fellows in our program join a diverse and dynamic cardiothoracic anesthesiology team that is rich with clinical, educational, and research experience. Collectively, our additional expertise ranges from critical care medicine, to pediatric anesthesiology, heart and lung transplant, perioperative ultrasound, echocardiographic and clinical research, and applied education theory. Our faculty are also diverse in representation, coming together from many cultures, races, ethnicities, religions, and identities for the common goal of delivering expert, compassionate care of the highest caliber to all patients with cardiothoracic conditions regardless of background

Our 12-month fellowship provides a structured, mentored approach to learning and progressive independence. Our internationally renowned surgeons and cardiologists perform a broad range of routine, complex, and cutting-edge procedures, providing abundant clinical exposure to our graduates in their path to independent practice. We perform heart transplants and implant circulatory assist devices, we are recognized as a high volume aortic surgery with a focus on open repair, and we provide exposure to minimally invasive techniques such as robotic cardiac surgery and a cutting-edge structural heart programWe also partner with multidisciplinary teams to provide our fellows with opportunities to broaden their clinical horizons and pursue their academic interests.

Thank you for your interest in our program, and I invite you to explore further as we describe our fellowship in more detail in the sections below.
