Why the study?
Does transsubxiphoidal left ventricular puncture safely allow evaluation of left ventricular function in patients with mechanical prosthetic aortic and mitral valves?
Does transsubxiphoidal left ventricular puncture safely allow evaluation of left ventricular function in patients with mechanical prosthetic aortic and mitral valves?
Transsubxiphoidal left ventricular puncture is a safe and feasible alternative to transapical puncture for hemodynamic assessment in patients with mechanical aortic and mitral valves.
No takes yet. Share an insight, caveat, or question.
May support TSLVP feasibility in double mechanical valves; hypothesis-generating and requires prospective validation before practice change.
Zuguchi et al. (2001) studied this question.
