A presystolic murmur, also called presystolic accentuation, is a type of diastolic heart murmur typically associated with the opening snap in mitral valve stenosis. It is heard following the middiastolic rumble of the stenotic valve,[1] during the diastasis phase, making it a "late diastolic" murmur.
The murmur is heard due to antegrade flow of blood through a progressively narrowing mitral opening during the end of the atrial systole. This antegrade flow through the mitral valve before it completely closes appears to be the result of a pressure gradient at the end of diastole.[1] As its name so indicates, the presystolic murmur is heard before the mitral valve produces the S1 heart sound.
Less often, a presystolic murmur can be heard when a right atrial myxoma causes a tricuspid valve obstruction to blood flow.[1]

- Vertebral osteomyelitis associated with Granulicatella adiacens.
- Fukuda R1, Oki M, Ueda A, Yanagi H, Komatsu M, Itoh M, Oka A, Nishina M, Ozawa H, Takagi A.Author information 1Department of General Internal Medicine, Tokai University School of Medicine, Isehara, Kanagawa, Japan. f.ryuki@is.icc.u-tokai.ac.jpAbstractGranulicatella adiacens is a nutritionally variant streptococci. Only 3 cases of vertebral osteomyelitis due to these microorganisms have been reported. We experienced a 73-year-old male who consulted us due to fever and back pain of about 1-month duration. On examination, a presystolic murmur was heard in the apical region. Echocardiography showed prolapse of the mitral valve, but no vegetation was observed. MRI revealed osteomyelitis of lumbar vertebrae. As G. adiacens was detected in blood culture, it was determined as the cause of vertebral osteomyelitis, and combination antibiotics therapy was started. The condition improved, the patient underwent valvoplasty, and no trace of infective endocarditis was noted in the resected valve. All the previous cases had infection caused by G. adiacens and complicated with infective endocarditis. This is the first case without infective endocarditis. Vertebral osteomyelitis due to NVS is very rare. Since nutritionally variant streptococci do not grow in common culture media, and since the sensitivity of isolation by standard conventional biochemical methods is low, the condition may be misdiagnosed as blood-culture-negative vertebral osteomyelitis. Therefore, the possibility of nutritionally variant streptococci infection should be considered if a patient with vertebral osteomyelitis shows a positive Gram stain but negative blood cultures.

She had begun to experience unusual fatigue from the age of 40 years. Cardiac examination revealed a single S2, Levine grade II/VI presystolic murmur in the 5th left sternal border, and a right parasternal impulse. Echocardiography showed dilated right chambers and absence of pulmonary valve leaflets. Doppler echocardiography at the pulmonary annulus revealed a 'to and fro' pattern. Cardiac catheterization indicated the same diastolic pressures in the pulmonary artery and right ventricle. The diagnosis was absent pulmonary valve syndrome. Administration of a diuretic agent resulted in almost immediate improvement of symptoms. Absent pulmonary valve syndrome, generally associated with tetralogy of Fallot, often causes severe respiratory failure or right heart failure during infancy. A case of such long survival without associated cardiac anomalies is very rare.

- Gehlen H1, Kroker K, Deegen E, Stadler P.Author information 1Klinik für Pferde, Tierärztliche Hochschule Hannover. heidrun.gehlen@tiho-hannover.deAbstract30 warmblood horses were examined before and after sedation with 20 micrograms/kg BW detomidine, to determine changes of cardiac function parameters, using B-mode, M-mode and Doppler echocardiography. 15 horses showed a heart murmur, but no clinical signs of cardiac heart failure, 15 horses had neither a heart murmur nor other signs of cardiac disease. After sedation with detomidine we could recognise a significant increase of end-diastolic left atrium diameter, an increase of end-systolic left ventricular diameter and aortic root diameter. The end-systolic thickness of papillary muscle and interventricular septum showed a decrease. Fractional shortening and amplitude of left ventricular wall motion was decreased after sedation. The mitral valve echogram revealed a presystolic valve closure and an inflection in the Ac slope (B-notch) in xy horses before sedation. Both increased after sedation with detomidine. Doppler echocardiography showed a decrease of blood flow velocity and velocity time integral (VTI) in the left and right ventricular outflow tract after sedation. Regurgitant flow signals were intensified following sedation in xy horses, especially at the mitral valve.
