Heart Murmur

Heart Murmurs


Presentation

  • This article presents the case of a 45-year-old woman who presented with a history of a heart murmur and progressively worsening dyspnea on exertion.[ncbi.nlm.nih.gov]
  • METHODS: This is a retrospective review of patients aged 15 years presenting to our HMC between March 2010 and December 2015 with an asymptomatic systolic murmur.[ncbi.nlm.nih.gov]
  • In order to extract the most relevant features from TFRs, two specific approaches for dimensionality reduction are presented: feature extraction by linear decomposition, and tiling partition of the t-f plane.[ncbi.nlm.nih.gov]
  • Before the consultation, parents who received a fact sheet presented a lower mean STAI state anxiety level (33.2) than those who did not (35.3), but the difference was not significant (p 0.09).[ncbi.nlm.nih.gov]
  • Abstract The paper presents a novel screening method to indicate congenital heart diseases (CHD) which otherwise would remain undetected because of their low level.[ncbi.nlm.nih.gov]
Carotid Bruit
  • The carotid bruit is heard in 4% (PC) and 2% (SMO).(ABSTRACT TRUNCATED AT 250 WORDS).[ncbi.nlm.nih.gov]
  • bruit (supraclavicular systolic murmur) Supraclavicular area, ejection systolic, grade 2-3 AS Peripheral pulmonary stenosis (pulmonary flow murmur of newborn) Upper left sternal border, grade 1-2, radiates to axillae and back, usually disappears by 6[patient.info]
  • The radiation of the AS murmur is often mistaken for a carotid bruit. The AS murmur is also known to radiate to the cardiac apex on occasion, making it difficult to distinguish if mitral regurgitation is also present.[healio.com]
Late Systolic Murmur
  • systolic murmur Left parasternal pansystolic murmur Machinery murmur Mid-diastolic mitral murmur Mid-diastolic murmur Mid-diastolic tricuspid murmur Mid-systolic murmur Mitral late systolic murmur Multiple non-ejection systolic clicks Murmur On examination[icd9data.com]
  • Late Systolic Murmurs The murmur of mitral or tricuspid valve prolapse is the only significant late systolic murmur. Tricuspid valve prolapse is relatively rare and usually not clinically significant.[healio.com]
Pulmonary Systolic Murmur
  • systolic murmur On examination - systolic murmur On examination - systolic murmur at apex On examination - tricuspid murmur Organic heart murmur Pansystolic murmur Plateau cardiac murmur Postpartum (after childbirth) heart murmur Postpartum heart murmur[icd9data.com]
Weak Pulse
  • pulse Type 2 Excludes foreign body in throat ( T17.2- ) wheezing ( R06.2 ) cardiac R01.1 Murmur (cardiac) (heart) (organic) R01.1 systolic R01.1 ICD-10-CM Codes Adjacent To R01.1 Q99.8 Other specified chromosome abnormalities Q99.9 Chromosomal abnormality[icd10data.com]
Suggestibility
  • The achieved results suggest that the proposed method achieves slightly better results using a smaller feature set.[ncbi.nlm.nih.gov]
  • Higher negative predictive value and lower positive predictive value suggest an echocardiographic second-level confirmation in the case of heart murmur at clinical examination suspected for CHD, probably unnecessary in the case of negative auscultative[ncbi.nlm.nih.gov]
  • We suggest that hypoplasia of pulmonary artery branches, in relation to the main trunk, is the main cause of the murmur resembling pulmonary artery stenosis.[ncbi.nlm.nih.gov]
  • In conclusion, our findings suggest that a transient heart murmur in the late neonatal period is caused by transient branch pulmonary arteries stenosis during the transitional circulation from fetus to neonates.[ncbi.nlm.nih.gov]

Workup

  • Evaluation of murmurs [ 11 ] Systolic murmurs Midsystolic: Grade 2 or less: Asymptomatic and no associated signs – no further workup. Symptomatic or other signs of cardiac disease - echocardiogram. Grade 3 or more - echocardiogram.[patient.info]

Treatment

  • We see that 14 children (43.75%) had a structural abnormality of the heart that requires further treatment and monitoring.[ncbi.nlm.nih.gov]
  • Treatments Generally, heart murmurs do not require treatment. However, pathologic heart murmurs may require treatment or at least monitoring over time. Treatment may include medication, surgery or other procedures performed in the cath lab.[wexnermedical.osu.edu]
  • A heart murmur itself does not require treatment. If it is caused by a more serious heart condition, your doctor may recommend treatment for that heart condition. Treatment may include medicines, cardiac catheterization, or surgery.[nhlbi.nih.gov]
  • Treatment Benign heart murmurs do not require treatment. Treatment of other heart murmurs depends on the underlying cause and extent of the problem.[cancercarewny.com]

Prognosis

  • For people with other types of heart murmurs, the prognosis depends on the type of heart problem and its severity. In general, even when heart surgery is required, the prognosis is good.[drugs.com]
  • Prognosis Many heart murmurs are considered harmless and are left untreated. These are known as innocent heart murmurs. Prognosis for abnormal heart murmurs depends on the type and severity of the heart problem causing them.[baptisthealth.com]
  • Prognosis Most children with innocent heart murmurs grow out of them by the time they reach adulthood. Severe causes of heart murmurs may progress to severe symptoms and death. Key terms Atria — The upper two chambers of the heart.[medical-dictionary.thefreedictionary.com]

Etiology

  • Practically all categories in the chapter could be designated 'not otherwise specified', 'unknown etiology' or 'transient'.[icd10data.com]
  • On the basis of the images in this single case, any of the mechanisms, and in particular the first 3, could be etiological factors.[doi.org]
  • Location The anatomic location where the murmur is best heard is an important factor in determining the etiology of the lesion. The four main “listening posts” on the chest are described below.[healio.com]

Prevention

  • To help reduce your risk of developing an abnormal heart murmur: Get prompt testing and treatment for strep throat to prevent rheumatic fever. Reduce your risk of atherosclerosis to help prevent valvular heart disease in the distant future.[cancercarewny.com]
  • Ask your doctor if you need to take preventive antibiotics.[winchesterhospital.org]
  • Steps You Can Take to Prevent Cardiovascular Complications Taking early steps to understand a heart murmur symptoms or diagnosis is important to maintaining strong heart health and preventing major problems later on.[polyclinic.com]
  • In most cases, you can't prevent heart murmurs. The exception is that if you treat an underlying condition, such as high blood pressure, or you avoid heart valve infection, heart murmurs are stopped before they start.[webmd.com]
