[Phenocardiographic and auscultatory patterns in patients with normally functioning Björk-Shiley aortic prosthesis (author's transl)]. 1978

R Russo, and G Oreto, and L Compostella, and D Fiore, and G Fasoli

Phonocardiographic examination was carried out in 40 patients who had undergone to aortic valve replacement with the Björk-Shiley prothesis. The regular function of the prothesis was evaluated on the basis of the physical, radiological and electrocardiographic data. In the majority of the cases the first sound was slight. The prosthetic closing sound was made of two components (a2, A2) and the opening sound by one or more components (C1, C2, C3). A sistolic aortic murmur was always present, and a diastolic murmur has been found in 20% of the cases.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010701	Phonocardiography	Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine.	Phonocardiographies

D006337	Heart Murmurs	Heart sounds caused by vibrations resulting from the flow of blood through the heart. Heart murmurs can be examined by HEART AUSCULTATION, and analyzed by their intensity (6 grades), duration, timing (systolic, diastolic, or continuous), location, transmission, and quality (musical, vibratory, blowing, etc).

D006347	Heart Sounds	The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of SYSTOLE and is heard as a "lubb" sound; the second is produced by the closing of the AORTIC VALVE and PULMONARY VALVE and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the HEART ATRIA; and the fourth is produced by atrial contraction and ventricular filling.
