Clinical validation of coronary artery flow through an intracoronary shunt during off-pump coronary artery bypass grafting

A novel approach: how an intracoronary shunt proved to be lifesaving

Outcomes and complications following internal massage in cardiac surgery are unknown due to the lack of cumulative effort to capture those events and subsequently developing a registry. Therefore, under the circumstances there are no algorithms defined in the literature. This case report outlines the importance of sound decision-making under pressure in order to achieve a favourable outcome. A potential solution is outlined to a very complex and rare problem: anastomotic disruption during internal cardiac massage in an intensive care unit setting, demonstrating the use of an intracoronary shunt for initial stabilization prior to a definitive procedure.

Minimally invasive direct coronary artery bypass for left anterior descending artery revascularization - analysis of 300 cases

Introduction

Minimally invasive direct coronary artery bypass (MIDCAB) grafting is performed via small, left anterolateral thoracotomy. The left internal mammary artery was grafted to the left anterior descending (LAD) artery in 300 consecutive patients.

Aim

In-hospital results were evaluated and compared with the conventional, off-pump coronary artery bypass graft procedure.

Material and methods

One hundred and sixty-three (54.33%) of 300 patients underwent staged hybrid coronary revascularization, 93 (31%) were treated for a single LAD lesion, and 44 (14.67%) were treated for multi-vessel disease with reasonably incomplete revascularization. Major in-hospital cardiac adverse events and postoperative data were compared between groups.

Results

Preoperative data were similar between groups. However, the difference in left ventricular ejection fraction (p < 0.001) was significant. No conversions to sternotomy occurred during the primary MIDCAB procedures. Shorter operation time (p < 0.001), shorter postoperative mechanical ventilation time (p < 0.001), shorter intensive care unit stay (p < 0.001), and less red blood cell transfusion (p < 0.001) were noted in the MIDCAB group. Postoperative coronary angiography conducted in the MIDCAB group within one week after the operation showed that 2 of 163 patients developed graft occlusion. These patients underwent conventional CABG and recovered well. No significant differences were observed in postoperative MI, delayed wound healing or 30-day in-hospital mortality between the two groups.

Conclusions

The use of a chest wall lifting system and modified stabilizer makes the MIDCAB procedure safer and easier. The MIDCAB procedure is demonstrated to be a feasible and minimally invasive alternative for patients with coronary artery disease involving LAD lesions.
