Late systolic murmurs start after S1 and, if left sided, extend up to S2, usually in a crescendo manner. Causes include mitral valve prolapse, tricuspid valve prolapse and papillary muscle dysfunction. Holosystolic (pansystolic) murmurs start at S1 and extend up to S2. They are usually due to regurgitation in cases such as mitral regurgitation ...
Pulmonary valve stenosis is a crescendo-decrescendo systolic murmur. One can hear it best at the left upper sternal border. It has association with a systolic ejection click that increases with inspiration. This finding results from an increased venous return to the right side of the heart. Pulmonary stenosis sometimes radiates to the left ...
Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [1] EA has great anatomical heterogeneity that generates a wide spectrum of clinical features at presentation and is complicated by the fact that the ...
A loud murmur with a thrill. A loud murmur with a thrill. The murmur is so loud that it is audible with only the rim of the stethoscope touching the chest. A loud murmur with a thrill. The murmur is audible with the stethoscope not touching the chest but lifted just off it. The Levine scaling system persists as the gold standard for grading ...
A right-sided S3 is best heard at the lower left sternal border. The way to distinguish between left and right-sided S3 is to observe whether it increases in intensity with inhalation or exhalation. A right-sided S3 will increase on inhalation, while a left-sided S3 will increase on exhalation. [1]
The presence of a murmur at the apex can be misinterpreted as mitral regurgitation. However, the apical murmur of the Gallavardin phenomenon does not radiate to the left axilla and is accentuated by a slowing of the heart rate (such as a compensatory pause after a premature beat) whereas the mitral regurgitation murmur does not change. [2]
Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur. [3] Early systolic clicks may also be present in some patients. [4] Aortic and pulmonary stenosis may cause an ejection click [5] immediately after S 1.
Findings on clinical examination depend on the severity and duration of MR. The mitral component of the first heart sound is usually soft and with a laterally displaced apex beat, [6] often with heave. [7] The first heart sound is followed by a high-pitched holosystolic murmur at the apex, radiating to the back or clavicular area. [6]
