Minimally invasive coronary artery bypass grafting using the right gastroepiploic artery without pump
Insights
The right gastroepiploic artery (RGEA) is a feasible conduit for coronary artery bypass grafting without cardiopulmonary bypass (CPB). This minimally invasive technique shows promise for reoperative cardiac surgery.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Surgery
Background:
- Coronary artery bypass grafting (CABG) traditionally involves cardiopulmonary bypass (CPB).
- Alternative conduits and techniques are sought to improve patient outcomes and reduce surgical invasiveness.
Purpose of the Study:
- To assess the feasibility of using the right gastroepiploic artery (RGEA) for coronary artery bypass grafting without CPB.
- To evaluate the safety and efficacy of this minimally invasive approach for revascularizing the inferior aspect of the heart.
Main Methods:
- A cohort of patients underwent RGEA grafting to coronary arteries, including the right coronary artery and its branches.
- The procedure utilized a small midline incision and did not require CPB.
- Graft patency was assessed postoperatively using Doppler echocardiography and angiography.
Main Results:
- No perioperative mortality or complications were observed.
- Eight out of ten grafts demonstrated patency on Doppler echocardiography.
- Angiographic assessment confirmed patency in four out of five cases, with no recurrence of angina.
Conclusions:
- The RGEA is a suitable conduit for revascularizing the inferior cardiac region.
- Minimally invasive CABG without CPB using the RGEA is feasible and safe.
- This technique is particularly advantageous for selective reoperative cardiac procedures.
Objective:
To explore the feasibility to operate on the right coronary artery and its branches utilizing the right gastroepiploic artery (RGEA) without cardiopulmonary bypass (CPB). All cases were performed since May 1996.
Methods:
A small mid-line incision including splitting of the lower sternum gave excellent exposure. The inferior surface of the heart was dissected to expose and stabilize the target vessel. The heart rate was controlled with a Diltiazem drip. CPB was not necessary in any case. The right coronary artery was bypassed in four patients, the posterior descending artery branch in five patients and the terminal circumflex of the left coronary artery in one patient. After grafting, patency of the anastomosis was demonstrated by Doppler echocardiogram.
Results:
No patient had perioperative mortality or complications. No patient had recurrent angina. Color Doppler echocardiographic imaging studies before discharge confirmed patency of the graft in eight of ten cases. In two cases, the gastroepiploic artery could not be visualized. Angiographic visualization was positive in four out of five cases.
Conclusions:
The gastroepiploic artery is an excellent conduit for vascularization of the inferior aspect of the heart. The operation can be done using a minimally invasive technique and without the use of cardiopulmonary bypass. This approach seems especially applicable in selective reoperative cases.
