Roger’s murmur

Description

Roger’s murmur describes a loud holosystolic murmur of a ventricular septal defect.

The murmur is best demonstrated at the left upper sternal border, accompanied by a harsh thrill, and compared to the sound of a ‘rushing waterfall’. The smaller the ventricular septal defect, the greater the turbulence of flow and the louder the murmur. 


History of Roger’s murmur

1879 – Roger provided the first clinicopathological overview, through the correlation of his autopsy findings of interventricular defects with the murmurs previously documented in patients’ records. His description of the murmur:

… a murmur loud and long; it is single, begins at systole and is prolonged so as to hide the natural tic-tac; it has its maximum… in the upper third of the precardial region; it is median, like the septum itself

The interventricular defects described by Roger:

A developmental defect of the heart occurs from which cyanosis does not ensue in spite of the fact that a communication exists between the cavities of the two ventricles…This congenital defect… comprises a defect in the interventricular septum

…in the upper portion of the interventricular septum beneath the mitral valve is an orifice which establishes a communication between the two ventricles; one of the most frequent (defects) which I have encountered… is the communication between the two ventricles
