6. Fig. 5
Survey question: “What do you think will be the most important driving force for the expansion of minimally invasive coronary artery bypass grafting?” Answers: (1) patient demand; (2) cardiologist demand; (3) economic benefits of procedure; (4) limited intermediate outcome of catheter intervention.
