10 Possible Causes for Artrioventricular Canal Defect, Diastolic Murmur, Pulmonary Systolic Murmur

  • Patent Ductus Arteriosus

    Course and Complications  Ejection systolic murmur at birth (due to pulmonary hypertension)  continuous murmur after a few weeks  Development of Pulmonary arterial hypertension[] In patients with a large left-to-right shunt, a low-pitched mitral mid-diastolic murmur may be audible at the apex.[] A heart murmur occurs in the pulmonary area; the murmur may be continuous, systolic with a short diastolic component, or only systolic, depending on the pulmonary artery pressure[]

  • Large Ventricular Septal Defect

    […] vascular resistance decreases left to right shunt and converts systolic murmur in the one-sided murmur.[] A smaller defect will lead to a louder murmur Diastolic murmur : Diastolic rumble due to increased flow across mitral valve due to left-to right shunting.[] , loudest at the fourth intercostal space, usually with a thrill, and a loud and widely split pulmonic component of S2 With fixed pulmonary hypertension, diastolic murmur[]

  • Ostium Primum Atrial Septal Defect

    MurmursPulmonary ejection systolic murmur – Increased pulmonary flow • Tricuspid murmur – is heard over left sternal edge louder on inspiration • Graham-Steell murmur[] […] more audible and a Graham-Steel pulmonary regurgitation diastolic murmur appears.[] Typically, pulmonary valve stenosis has an associated systolic ejection click, the murmur of pulmonary valve stenosis tends to be more harsh than the systolic murmur associated[]

  • Atrial Septal Defect

    MurmursPulmonary ejection systolic murmur – Increased pulmonary flow • Tricuspid murmur – is heard over left sternal edge louder on inspiration • Graham-Steell murmur[] There is a brief diamond shaped murmur in early systole and another brief diamond shaped murmur in early diastole In the anatomy tab you see an enlarged right atrium and right[] If diastolic murmur heard, implies increased flow across tricuspid and elevated pulmonary blood flow With increased L to R shunting, may have ventricular heave CXR: Enlarged[]

  • Ventricular Septal Defect

    In addition to a pansystolic murmur, there may also be a mid/end diastolic murmur mimicking mitral stenosis as well as an ejection systolic murmur mimicking aortic stenosis[] There is further turbulent flow into the left ventricle from the left atrium causing the diastolic murmur.[] Although heart sounds are normal, a systolic click and a grade iii/iv systolic murmur in the pulmonary area is heard.[]

  • Tetralogy of Fallot

    Single S2 - pulmonary valve closure not heard. Systolic ejection murmur - varies in intensity inversely with the degree of RVOT obstruction.[] […] a diastolic murmur due to pulmonary regurgitation.[] Clinical assessment of pulmonary regurgitation alone is unreliable as a short diastolic murmur may be found both in very mild or extremely severe regurgitation.[]

  • Mitral Valve Prolapse

    , Ischemic Attack, Transient, Mitral Valve, Mitral Valve Insufficiency, Mitral Valve Prolapse, Pulmonary Artery, Rheumatic Heart Disease, Stroke, Stroke Volume, Syncope, Systole[] Changes in LV end-diastolic volume result in changes in the timing of the midsystolic click(s) and murmur.[] […] blood pressures and assessments for mitral systolic murmur and mid-systolic click.[]

  • Endocardial Cushion Defect

    A systolic murmur of a ventricular septal defect can be heard as well as the systolic murmur of mitral insufficiency.[] ; and sometimes a diastolic murmur at the apex and low left sternal border (see table Heart Murmur Intensity ).[] Identification of a heart murmur (most likely pansystolic, but also ejection systolic or apical mid-diastolic) during cardiac auscultation can raise sufficient clinical suspicion[]

  • Congenital Heart Disease

    […] ejection-type murmurs at the left lower sternal border over the pulmonary area Anemia Weight gain The current medication regimen should also be reviewed for appropriate indications[] This accounts for seven to eight percent of congenital heart defects. Complete or partial artrioventricular canal defect .[] […] veins with prominent A and V waves Diffuse, displaced left ventricular impulse; palpable RV impulse Increased first heart sound; persistent splitting of second heart sound Systolic[]

  • Pulmonary Veno-Occlusive Disease

    The sequelae of such an increase in pressure, including a pansystolic murmur of tricuspid regurgitation, a diastolic murmur of pulmonary regurgitation and a right ventricular[] During the physical examination, auscultation of the lungs and the heart can provide valuable clues, such as systolic murmurs (which may point to tricuspid regurgitation)[] Typical clinical signs of PH are found with right ventricular heave, a loud pulmonary component of the second heart sound and a systolic murmur of tricuspid regurgitation[]
