What is the Difference Between Bypass and Open Heart Surgery?

🆚 Go to Comparative Table 🆚

Open heart surgery and bypass surgery are both complex procedures performed to treat heart problems. However, there are some key differences between the two:

Open Heart Surgery:

  • Involves opening the chest to perform surgery on the muscles, valves, or arteries of the heart.
  • May or may not involve an opening of the heart itself.
  • Can include surgeries such as coronary angioplasty or heart transplants.
  • Requires opening the chest wall to make the heart easier for the surgeon to reach.

Bypass Surgery:

  • A type of open-heart surgery.
  • Performed when blood flow through the arteries is obstructed.
  • Involves grafting a blood vessel from the chest or leg onto the coronary artery that has a blockage, bypassing the blocked part of the artery and allowing blood to flow freely to the heart.
  • Can be performed using a heart-lung bypass machine (on-pump surgery) or without it (off-pump surgery, also called "beating heart surgery").

In summary, open heart surgery is a broader term that encompasses various surgeries on the heart, while bypass surgery is a specific type of open-heart surgery that focuses on bypassing blocked arteries to improve blood flow to the heart.

Comparative Table: Bypass vs Open Heart Surgery

Open-heart surgery and bypass surgery are two effective surgical procedures to treat cardiac diseases. Here is a table comparing the differences between the two:

Feature Open-Heart Surgery Bypass Surgery
Definition Any procedure that involves opening the chest to access the heart, muscles, valves, or arteries. A type of open-heart surgery that creates alternate pathways to direct blood flow around a blocked artery.
Purpose Treats heart problems such as heart failure, congenital heart defects, arrhythmias, aneurysms, and coronary artery disease. Treats coronary artery disease by creating a bypass around the blocked section of the artery.
Incision Involves an 8 to 10-inch incision in the chest, breaking through all or part of the patient's breastbone. Involves small incisions on the chest, leg, or wrist to access healthy veins or arteries for creating an alternate pathway.
Heart Access Requires opening the chest wall to make the heart easier for the surgeon to reach. Does not necessarily involve opening the heart; grafted blood vessel ensures that the blocked part of the arteries is bypassed.
Heart-Lung Bypass Machine Patient may be connected to a heart-lung bypass machine after the heart is located. Heart-lung bypass machine may or may not be necessary, depending on the technique used.

It is essential to consult a trusted healthcare professional to determine the most effective and safe surgical procedure for the patient, considering factors such as medical conditions, severity of the issue, type of ailment, and age of the patient.
