Answer 1

An incision made through the sternal region for open heart surgery that divides the thoracic cavity into equal left and right parts is along the midsagittal plane, allowing direct access to the heart within the pericardial cavity.

Step-by-step explanation:

Dr. Mitchell performs open heart surgery, which requires access to the human heart located within the thoracic cavity. The heart is situated in the mediastinum, protected by the pericardium and housed within the pericardial cavity. When performing open-heart surgery, an incision made to divide the thoracic cavity into equal left and right parts along the sternal region is typically along the midsagittal plane. This is because it aligns with the natural orientation of the heart, with the slight deviation of the apex to the left.

A midsagittal incision allows for the best access to the heart, dividing the body into symmetrical halves and providing a direct approach to the pericardial cavity and the great veins and arteries attached to the heart, such as the superior and inferior venae cavae, the aorta, and the pulmonary trunk.

Answer 2

The incision of the open heart surgery should be along the sternum and typically 6 to 8 inch long.

Explanation;

• Open heart surgery is thought to be the major surgery in adults.
• It is usually the surgery of open heart in which heart is exposed to the surgeon by the incision which is in the middle of ribs and thoracic cavity.
• In advance techniques incision length is only 2 to 4 inches and it takes average four weeks to fully recover.
• It is commonly used for coronary artery bypass grafting (CABG).
