Aim:
To search for a new method of left ventricular intubation in rat.
Methods:
The wire of percutaneous transluminal coronary angioplasty (PTCA) was put into carotid artery through external carotid artery. Then supported by guide wire, the PE50 tube was advanced into left ventricle.
Results:
Left ventricular intubation with PTCA guide wire could be performed in 30 rats and successfully repeated in 27 animals.
Conclusion:
The new left ventricular intubation technology in rats is simple and provides a reproducible method.
