10 Possible Causes for Heart Murmur Increased with Amyl Nitrite

  • Hypertrophic Cardiomyopathy

    Alfares AA, Kelly MA, McDermott G, Funke BH, Lebo MS, Baxter SB, Shen J, McLaughlin HM, Clark EH, Babb LJ, Cox SW, DePalma SR, Ho CY, Seidman JG, Seidman CE, Rehm HL. Results of clinical genetic testing of 2,912 probands with hypertrophic cardiomyopathy: expanded panels offer limited additional sensitivity. Genet Med.[…][ncbi.nlm.nih.gov]

  • Aortic Valve Stenosis

    Aortic stenosis is the most common form of valvular heart disease. Progression of aortic stenosis is very slow and highly variable. Decisions about when to perform valve surgery are made by subjective assessment of patient symptoms and objective measures of the valve and ventricular function by transthoracic[…][ncbi.nlm.nih.gov]

  • Mitral Valve Prolapse

    A 31-year-old male was diagnosed with congestive heart failure due to left ventricular noncompaction and coarctation of the aorta by echocardiography and computed tomography. He also developed mitral valve prolapse of the posteromedial commissural leaflet due to rupture of chordae tendineae. Segmental leaflet[…][ncbi.nlm.nih.gov]

  • Tricuspid Valve Insufficiency

    Tricuspid valve insufficiency, or tricuspid regurgitation, is a condition that involves a jet of blood pathologically leaking backward from the right ventricle into the right atrium during the systolic phase of the cardiac cycle. Tricuspid valve insufficiency is widely classified into two categories: the primary type,[…][symptoma.com]

  • Tricuspid Stenosis

    Tricuspid valve stenosis is a condition involving a restriction of the orifice of the tricuspid valve, which correspondingly leads to diminished blood flow from the right atrium to the right ventricle. Tricuspid valve stenosis is rarely a condition solely responsible for the symptoms reported by affected patients.[…][symptoma.com]

  • Mitral Valve Stenosis

    Mitral stenosis (mitral valve stenosis) is a narrowing of the mitral valve opening that increases resistance to blood flow from the left atrium to the left ventricle. In mitral stenosis, blood flow through the narrowed valve opening is reduced. As a result, the volume and pressure of blood in the left atrium[…][web.archive.org]

  • Pulmonary Valve Stenosis

    Abstract The familial association of pulmonary stenosis, atrial septal defect, and unique electrocardiographic abnormalities involving a mother and two children is reported. Familial pulmonary stenosis not occurring as part of a named syndrome or without associated multiple congenital abnormalities is rare. The[…][ncbi.nlm.nih.gov]

  • Innocent Cardiac Murmurs

    Congenital Heart Defects A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They[…][icdlist.com]
