Answer 1

Ans) 9) Minimal invasive procedure

Explaination:

- “In some situations, mitral valve disease is not life threatening and does not require surgery”. “If surgery is recommended and you're high risk for surgery, we can either repair or replace the mitral valve with minimally invasive procedures.

10) a. Oxygenate and pump the blood

Explaination:

- Cardiopulmonary bypass (CPB) is a technique in which a machine temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the patient's body. The CPB pump itself is often referred to as a heart–lung machine or "the pump".

11) d. Infusing a cold cardioplegic solution into the circulatory system

Explaination:

- Intentional stopping of the heart during cardiac surgery achieved with a cardioplegic solution.

12) d. Have a cardiac stabilizer put in place

Explaination:

- Cardiac stabilizer for minimally invasive direct coronary artery bypass. A simple and effective device that is useful in reducing cardiac motion, enabling the surgeon to perform a precise direct left internal mammary artery anastomosis to the left anterior descending coronary artery on a beating heart.
