minimally invasive direct coronary artery bypass

Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia.


Minimally invasive direct coronary artery bypass. Heart surgery in which coronary bypass (usually with a single graft) is performed on a blood-filled beating heart, without a heart-lung machine, via a small incision in the chest wall.

Incisions are smaller, sternum is not opened, recuperation period shorter, overall cost lower.
Less than half of CABG patients are candidates for MIDCAB.

minimally invasive direct coronary artery bypass

Abbreviation: MIDCAB
The placement of a coronary artery graft without stopping the heart or using a cardiopulmonary bypass (heart-lung machine). A thoracotomy rather than a medial sternotomy is used to access the heart, which is then stabilized by use of a compression or suction device to decrease movement. The procedure is used primarily for grafting a single vessel, usually the left or right internal mammary artery. Although MIDCAB has the advantages of lower surgical costs and possibly a decreased risk of complications, it has the disadvantages of limited surgical visibility and more difficult suturing.
Synonym: off-pump coronary artery bypass
