Relevance: Gastric cancer is the second leading cause of malignancies of the gastrointestinal tract and the fifth leading cause in overall cancer statistics. Diseases of the cardiovascular system are the leading cause of death worldwide. A high prevalence of both diseases increases the chances of their co-morbidity. The article aimed present a case where a patient undergoes two simultaneous procedures for two diseases and discuss possible surgical tactics, advantages, and disadvantages. Results: In this case report, we present simultaneous surgical procedures performed on a 49-year-old male with a history of congenital bicuspid aortic valve and gastric cancer, found incidentally on upper gastrointestinal (GI) endoscopy. Since the patient was a good fit, he qualified for simultaneous surgery on the heart and abdomen. The surgery results were good, and the patient was discharged 8 days after surgery. Conclusion: Performing simultaneous surgery for both the abdomen and heart can be a safe procedure that allows people with malignant diseases to receive adjuvant therapy faster by minimizing the interval between surgeries.
