Summary of the Mayo clinic experience with direct left ventricular puncture
Key result
Direct LV puncture provides safe, high-yield diagnostic data in complex redo valve patients.
Why the study?
Hemodynamic assessment of patients with prosthetic valves is challenging due to limitations of noninvasive techniques and difficulty accessing the left ventricle for direct pressure measurements.
Does direct percutaneous left ventricular puncture provide safe and useful diagnostic information in patients with prosthetic valves?
Population
Patients with valvular prostheses requiring hemodynamic assessment
Comparison

Cite This Study
Ommen et al. (1998) conducted an observational in Valvular prostheses. Direct left ventricular puncture was evaluated on Safety and diagnostic utility. Direct left ventricular puncture is a safe technique that provides significant diagnostic information in patients with prior cardiac surgery and multiple valvular prostheses.
