Summary

During cardiac displacement for off-pump coronary artery bypass(OPCAB) surgery, the presence of air underneath the displaced heart compromises the transgastric (TG) window for transoesophageal echocardiography(TOE). The investigators hypothesised that placing a saline-filled glove would enhance TG transmission of ultrasound and facilitate TOE imaging for monitoring left-ventricular regional wall motion (LV-RWM). For left circumflex coronary artery (LCX) grafting in OPCAB surgery (n=13), mid-oesophageal (ME) and TG TOE images are recorded before cardiac displacement (T control), after displacing and stabilising the heart (T-displaced), and after placing a saline bag (saline-filled surgical glove) underneath the displaced heart (T-saline bag). Following data are determined by integrated TG and ME TOE views (ME+TG) at T-control, T-displaced and T-saline bag: number of readable segments (NRS) in a 17-segment model; NRSs in basal and mid-TG short axis views; NRS in 5-LV segments of the LCX territory; the incidence of inadequate monitoring of LV-RWM (NRS \< 14/16 except for the apex in 17-segment model).

Conditions

  • Ischemic Heart Disease

Interventions

PROCEDURE

placing saline bag during cardiac displacement

For grafting to LCX territory, the heart is displaced using positioner and a suction-type epicardial stabiliser is applied to the target area. The degree of cardiac displacement and the LV compression by stabilisers are adjusted for maximal surgical access and minimal haemodynamic instability.
