Left ventricular outflow tract obstruction (LVOTO) is a relatively common form of congenital heartdisease; it occurs in 2.8 per 10,000 births and accounts for 3 to 6 percent of congenital heart defects. 1 The levels of obstruction are classified anatomically[mhmedical.com]

A newly detected systolicmurmur in the left lower sternal border may be noticed upon physical examination; however a definitive diagnosis would require an echocardiographic examination.[kjim.org]
Cardiac examination revealed a Grade 2/6 cresendo-decrescendo systolicmurmur heard in the left third intercostal space close to the sternum. Except for hemoglobin of 10 g%, other biochemical investigations were within normal limits.[jiaecho.org]
HOCM should be suspected if a harsh systolicmurmur is noted in conjunction with left ventricular hypertrophy and deep, broad Q waves. Diagnosis can be confirmed by echocardiography.[openanesthesia.org]
Other forms of LVOTO are often asymptomatic and may be detected by the presence of a heartmurmur or abnormalities on ECG. Chest pain, dyspnea, and palpitations occur with increased activity as the degree of obstruction worsens.[mhmedical.com]

This article suggests that LVOT obstruction after the Senning procedure can be palliated by asynchronous septal contraction induced by AV sequential pacing, even if the activation is from LV apex, and avoid or postpone surgery in selected situations.[ncbi.nlm.nih.gov]
We suggest that postoperative atrial fibrillation may precipitate dynamic left ventricular outflow obstruction following mitral annuloplasty.[ncbi.nlm.nih.gov]
Echocardiographic and cardiac catheterization data suggest that left ventricular function need not be adversely affected by placement of a stent in the small infant ventricle; rather, ventricular function can be markedly improved.[ncbi.nlm.nih.gov]
This experience suggests that this approach is effective in relieving complex left ventricular outflow tract obstruction with good early results, and that it deserves more frequent application in children.[ncbi.nlm.nih.gov]

The majority of LVOTO (with the exception of calcific and rheumatic aortic stenosis) are congenital in etiology. Echocardiography has become an integral tool in the assessment of patients with congenital heart disease.[ncbi.nlm.nih.gov]
Incidence of LVOTO related to the mechanism of the mitral insufficiency and to the etiology demonstrates a direct relation to preoperative mitral valve prolapse (posterior leaflet /- anterior leaflet) of degenerative origin.[ncbi.nlm.nih.gov]
