Does echocardiographic guidance allow for safe and successful transthoracic left ventricular puncture in patients with an aortic valve prosthesis?
Echocardiographic guidance provides a safe and effective method for performing transthoracic left ventricular puncture to record pressures in patients with mechanical aortic valves.
Vignola et al. (1980) studied this question.
