Chest surgery is one of the most dangerous but under-appreciated surgical specialties. With declining interest in the specialty, Choi Kang Guk (Jo Jae Hyun), the new head of the Department of Thoracic and Cardiovascular Surgery at the prestigious Kwang Hee University Hospital, has no choice but to accept the only two applicants to his residency program. Lee Eun Sung (Ji Sung) graduated with mediocre grades from a newly established medical school in the south provinces, but he is determined to become a great surgeon. Nam Hye Suk (Kim Min Jung), on the other hand, graduated with perfect scores at the top of her medical school and has a brilliant medical mind. Eun Sung and Hye Suk try to impress Kang Guk with their medical skills while trying to help him restore the flagging reputation of the cardiothoracic department. When famous actor Lee Dong Gwon (Lee Ji Hoon) is admitted to their unit for cardiac arrhythmia, he realizes that Hye Suk is the classmate from elementary school that he has always had a crush on. Will the attention from Dong Gwon and Eun Sung keep Hye Suk from being able to do her job? “New Heart” is a 2007 South Korean drama series directed by Park Hong Kyun.
