Brief summary

The goal of this study is to compare the efficacy of a new harvesting technique for an arterial conduit(LIMA - Left Internal Mammary artery) in patients undergoing Coronary artery bypass grafting. The researcher will compare the 1. Time taken to harvest the artery 2. Flow of blood between the two techniques

Detailed description

Following consultation to our department, after a detailed history and clinical examination,patients with CAD, being planned for CABG, will be subjected to a detailed pre-op Echocardiogram and coronary angiogram. After necessary pre-op assessment, patient will be taken up for the surgery. Invasive monitoring will be done. Following dissection of LIMA by the above mentioned technique, flow of blood from the harvested LIMA, for one whole minute is noted. The operative time required for the dissection of LIMA will be noted and entered. The data between the two techniques will be compared statistically.

Interventions

PROCEDUREModified Carbo-dissection Technique

This technique comes the C02 blower with electrocautery. Thereby, producing vasodilatation due to the gas and dissection aided by the electrocautery.

PROCEDUREConventional Arm

This technique uses only the electrocautery as conventional model
