Many studies have shown a decrease in inotropic status (intrinsic function) after blockade of cardiac sympathetic innervation with thoracic epidural anesthesia (TEA) (4,5). There is no study in the literature investigating the cardiac effects of left thoracic ESP block. We think that left thoracic ESP block, like TEA, may also have cardiac effects. Therefore, we aimed to investigate the effect of left thoracic ESP block on left ventricular functions with transthoracic echocardiography (TTE).

Echocardiographic assessment of left ventricular function
Timeframe: Left ventricular function will be assessed by echocardiography 15 minutes before and 15 minutes after left high thoracic esp block.
