The bleeding is not significant, and the ultrasonic scalpel can easily stop this minor bleeding with a slight touch. However, the moment the doctor is about to move, bleeding starts again, showing that this heart is indeed scarred. It's a miracle if the patient recovers fully without major myocardial scars. The doctors are contemplating this as they proceed with the surgery.
The heart has inner and outer membranes, myocardium, blood vessels, and nerves. The recent bleeding spot is not from a major surface blood vessel, but myocardial bleeding suggests there might be a tear. After stopping the bleeding at the surface, the surgical instruments delve deeper into the wound. Time is of the essence; the surgical team avoids hesitation, striving to explore the depths of the injury.
