ABSTRACT
Objective To evaluate the collateral circulation after canine acute coronary artery occlusion with contrast real-time three-dimensional echocardiography (RT-3DE). Methods Left anterior descending coronary artery was ligated in 12 healthy mongrel dogs. All dogs underwent myocardial contrast echocardiography (MCE) before ligation, immediately after ligation, at 30 min and 180 min after ligation respectively, and myocardial mass with collateral supply was calculated. Results Different degrees of collateral circulation were established in all dogs after left anterior descending coronary artery ligation. At 30 min after ligation, the myocardial mass with collateral supply was (9.65±2.90) g, while at 180 min after ligation were (12.58±3.98) g (P<0.01). Conclusion The coronary collateral circulation can be observed clearly and myocardial mass with collateral supply can be quantified accurately with contrast RT-3DE.
