- Anemia
Post procedure, patient continued to do well with no recurrent heart failure symptoms, and there was resolution of hemolytic anemia. [bmccardiovascdisord.biomedcentral.com]
Other conditions include arrhythmias (abnormal heart rhythms), disease of the heart valves, aortic stenosis, structural or anatomical defects of the coronary arteries, severe anemia, hypertrophic obstructive cardiomyopathy, etc. [news-medical.net]
We report two cases of dynamic LVOT obstruction, the first patient with hypertension, mitral valve prolapse, anemia with associated hypovolemia and the second patient with vomiting and hypovolemia. [jiaecho.org]
- Sepsis
The dynamic LVOT obstruction may occur as a result of other conditions such as, aortic valve replacement for aortic stenosis, hypertensive hypertrophy, dehydration, sepsis, vasodilatation, acute myocardial infarction, and mitral valve repair; however, [kjim.org]

- Systolic Murmur
Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. [ncbi.nlm.nih.gov]
[…] hypertenison post AVR known LVH or HOCM increasing inotropes no tamponade Examination late systolic murmur over the praecordium Investigations ECHO: -> small LV cavity -> normal systolic function and no RWMA -> AVR functioning well -> flow acceleration [lifeinthefastlane.com]
A newly detected systolic murmur in the left lower sternal border may be noticed upon physical examination; however a definitive diagnosis would require an echocardiographic examination. [kjim.org]
HOCM should be suspected if a harsh systolic murmur is noted in conjunction with left ventricular hypertrophy and deep, broad Q waves. Diagnosis can be confirmed by echocardiography. [openanesthesia.org]
Outflow tract obstruction may cause a systolic murmur at the left sternal edge, radiating to the aortic and mitral areas. Most patients with left ventricular outflow murmurs also have mitral regurgitation. [patient.info]
- Heart Murmur
Other forms of LVOTO are often asymptomatic and may be detected by the presence of a heart murmur or abnormalities on ECG. Chest pain, dyspnea, and palpitations occur with increased activity as the degree of obstruction worsens. [mhmedical.com]

Results LV obstruction and prognosis Of the 526 study patients, 141 (27%) had LV obstruction. [onlinejacc.org]

Etiology
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]

Choi, and Kim: Dynamic left ventricular outflow tract obstruction without basal septal hypertrophy, caused by catecholamine therapy and volume depletion Abstract Hypertrophic cardiomyopathy (HCM) with hypertrophy of the basal septum is the most common etiology [kjim.org]
LVOT obstruction can be managed medically or invasively with surgical or percutaneous methods depending on the etiology and severity. [bmccardiovascdisord.biomedcentral.com]
Epidemiology
He has since completed further training in emergency medicine, clinical toxicology, clinical epidemiology and health professional education. [lifeinthefastlane.com]
Epidemiology Left ventricular outflow tract obstruction (LVOTO) occurs in 2.8 of 10,000 live births, accounting for 3 to 6 percent of congenital heart defects. [mhmedical.com]
Epidemiology HCM is the most common genetic cardiovascular disease. HCM is generally inherited as an autosomal dominant trait with variable penetrance and expressivity. A minority of cases reflect a sporadic, non-familial form of the disease. [patient.info]
Existing epidemiological studies might have underestimated the prevalence of HCM, however, owing to limited inclusion of individuals with early, incomplete phenotypic expression. [nature.com]

Pathophysiology
The pathophysiology, treatment, and role of intraoperative echocardiography of dynamic left ventricular outflow tract obstruction are discussed. [ncbi.nlm.nih.gov]
It is imperative, therefore, that the pathophysiologic processes involved in DLVOTO be fully understood in order to initiate safe and appropriate therapy in critically ill patients.Our presentation and discussion focus on a hypotensive critically ill [karger.com]
Pathophysiology Obstruction at any level causes increased left ventricular systolic pressure and wall stress and consequent left ventricular hypertrophy. Left ventricular hypertrophy produces subendocardial ischemia and diastolic dysfunction. [mhmedical.com]

Prevention
As such, subvalvular left ventricular outflow obstruction complicating valvular aortic stenosis is a potentially preventable cause of persistently high gradients that remains relatively frequently encountered after AVR. [ncbi.nlm.nih.gov]
Antibiotic medications are prescribed to prevent bacterial endocarditis, a potentially life-threatening condition. [163.178.103.176]
