AIM: The aim of this study was to evaluate the safety and efficacy of deep pericardial sling (DPS) versus lateral pericardial sutures (LPSs) for heart stabilization and adequate coronary artery exposure during off-pump coronary artery bypass surgery (OPCAB).
METHODS: One surgeon employed in 101 consecutive patients a series of four to six 2-0 polyglactin sutures placed laterally between the left phrenic nerve and the left pulmonary veins (LPS). Two other surgeons used in 104 consecutive patients a single 0-0 braided silk suture with moistened gauze placed in the oblique sinus of the posterior pericardium, between the inferior vena cava and the right lower pulmonary vein (DPS).
RESULTS: One conversion to beating heart surgery with cardiopulmonary bypass support occurred in each study group. No patient in the LPS group was converted to DPS technique. The use of LPSs allowed a number of distal anastomoses somewhat higher than the DPS technique (4.1±1.1 vs. 3.7±1.1, P=0.02). Postoperative results were similar in both study groups. A lower incidence of postoperative low-cardiac output syndrome and of prolonged need of inotropes has been observed in the LPS group, but the difference failed to reach statistical significance. One patient in the LPS group had postoperative left phrenic nerve palsy. One patient in the DPS group suffered of intraoperative bleeding secondary to rupture of the inferior vena cava likely related to placement of DPS, which was successfully repaired.
CONCLUSION: LPS technique is as effective as DPS technique and allows complete revascularization with a postoperative outcome similar to the latter technique.
