Percutaneous Suprasternal Puncture (Radner Technique) of the Left Ventricle

A Report of 646 Cases

An extension of the Radner technique to include the recording of pressures from the left ventricle, as well as all other chambers has proved a safe, simple and rapid procedure. In the first group of 363 cases, the left ventricle was accidentally entered in ten cases. When a deliberate attempt was made in the next 283 patients, the ventricle was entered 161 times without an increase in sequellae. In the last 119 cases, the left ventricle was entered in 74 per cent.

This method provides a safe yet rapid procedure for obtaining the aortic valve gradient, left ventricular end-diastolic pressure and the first derivative of the pressure curve, as well as other information.
