Transthoracic left ventricular puncture altered patient management in 68% of cases among patients with double valve replacement and suspected prosthetic dysfunction.

Does transthoracic left ventricular puncture provide better assessment of prosthetic valve dysfunction than noninvasive testing in patients with double mechanical valve replacement?
Direct left ventricular puncture is a valuable invasive diagnostic tool that alters clinical management in patients with double mechanical valves when noninvasive imaging is inadequate.
Walters et al. (2003) conducted an observational in Suspected prosthetic valve dysfunction (n=38). Transthoracic left ventricular puncture vs. Noninvasive testing was evaluated on Alteration of patient management. Transthoracic left ventricular puncture altered patient management in 68% of cases among patients with double valve replacement and suspected prosthetic dysfunction.
