Introduction Medical undergraduates' educational programs and clinical experiences are important factors in determining their preferred future career path. Unfortunately, the cardiac surgery specialty is experiencing a decline in medical graduates due to many influencing factors as a lack of involvement with the cardiac surgery specialty and a lack of training centers. A detailed evaluation of the student's knowledge and perceptions about cardiac surgery is required to assess the career options in a specialty like cardiac surgery. This study aims to evaluate medical students’ knowledge and perceptions of the cardiac surgical specialty. Methodology This is a cross-sectional study that was approved by the institutional research board of Umm Al-Qura University. Adapting a previously published questionnaire data to fit our scope and aims. Necessary adjustments were made adhering to the cardiac surgery experts' instructions. Data was collected through an electronic survey by Google Forms and distributed through social media apps. Results A total of 637 students participated in the study. The majority (75.2%) admitted to having little knowledge of the specialty of cardiac surgery, and 62.8% reported no interest in it. In addition, 88.9% had never done a cardiac surgery rotation before. One of the top concerns of becoming a cardiac surgeon (45.2%) was the amount of time spent studying and working. Conclusion The findings of our study highlight the value of using innovative and targeted learning methods for medical students to enhance their knowledge and pique their interest in cardiac surgery since it was evident that there was a misperception regarding the scope of cases dealt with by cardiac surgery as opposed to other surgical subspecialists.
