Intracardiac phonocardiography in man.

Intracardiac phonocardiography in ventricular septal defect.

It has been demonstrated that intracardiac phonocardiography provides precise localization of the source of cardiovascular sounds. Can this technic be of practical help in the diagnosis of small or complicated ventricular septal defects? Is a ventricular septal1 defect ever silent? What mechanisiims are responsible for the diastolic mlurmlurs in ventricular septal defect? In an attempt to answe...

Intracardiac Phonocardiography in Ventricular Septal Defect

Intracardiac phonocardiography. Description of a new simplified system.

F OLLOWING the pioneering works of Yamakawa et al. (1953)1 and of Soulie (1954),2 Luisada and Liu (1957) 3 4 described a method of recording intracardiac sound vibrations utilizing the electric signal of a pressure transducer through differentiation and filtration. At about the same time, Lewis et al. (1957)5 used a small barium titanate element at the tip of an intracardiac catheter. More rece...

Intracardiac Infection at the Tip of Hemodialysis Catheter: Life threatening Morbidity

Endocarditis and intracardiac infection have been increased recently especially in dialysis dependent renal failure patients. This is usually intractable infection to broad spectrum Antibiotic therapy and in most cases surgical intervention was necessary. We have presented 45 years old man with intracardiac infection at the tip of dialysis catheter that after catheter removal intracardiac infec...
