Advanced Cardiovascular Sonography Program (Minnesota)

Program description

The advanced cardiovascular sonographer (ACS) profession was developed to create a career track for sonographers who practice at an advanced level in the Echocardiography Laboratory.

Mayo Clinic's Advanced Cardiovascular Sonography Program is a 16-month online didactic program with clinical internships at Mayo Clinic's campus in Rochester, Minnesota. Online didactic content originates from the Rochester campus with the option of Web conference interaction.

Mayo Clinic's large, diverse patient population provides experience with a broad range of cardiac conditions, including many rare and complex disorders. Therefore, students are offered an exceptional education through high-quality didactic and clinical experiences required to develop a competent advanced cardiovascular sonographer.


The ACS program is accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP).

See accreditation information for Mayo Clinic College of Medicine and Science.


Mayo Clinic's campus in Rochester, Minnesota, includes an extensive outpatient complex, the inpatient Mayo Clinic Hospital — Rochester, and substantial research and education facilities. This Mayo Clinic site is among the largest, most advanced medical centers in the world.

Clinical education for the Advanced Cardiovascular Sonography Program is primarily conducted in the Mayo Clinic outpatient Echocardiography Laboratory (Echo Lab), though clinical rotations may also be scheduled at Mayo Clinic Hospital, Saint Marys Campus, a 1,265-bed facility that was founded in 1889.

The Mayo Clinic Echocardiography Laboratory in Rochester, one of the largest echocardiography laboratories in the world, features state-of-the-art diagnostic, therapeutic, educational and research facilities.

More than 30 full-feature scanning stations are located throughout the Mayo Clinic complex. Approximately 90 cardiac sonographers perform more than 250 echocardiographic procedures each day. The Echocardiography Laboratory is also active in clinical research and education.

Graduation and certification

Upon completion of the program, students receive a certificate of completion from Mayo Clinic School of Health Sciences. Graduates are eligible to take the Cardiovascular Credentialing International ACS credentialing examination.


The Advanced Cardiovascular Sonography Program is an online didactic program with 256 hours of online education and 256 hours of clinical education.

The clinical internship requires an on-site presence in a Mayo Clinic Echo Lab during the typical workweek of Monday through Friday. Timing and duration of each student's clinical hours is individualized and may range from four hours a week to eight hours a day spread throughout the term.

Class size

Mayo Clinic's Advanced Cardiovascular Sonography Program admits up to eight students. Class sizes and clinical groups are small, with one-on-one instruction provided.
