On cardiac catheterization, a left ventricular peak systolic outflow gradient of 50 mm Hg was noted; this decreased to 10 mm Hg following intravenous administration of 100 mg of cibenzoline. [ncbi.nlm.nih.gov]

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]

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]

Psychiatrical
- Suggestibility
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]
PRESENCE AND PREVALENCE OF OBSTRUCTION As is the case with many disease processes, initial clinical reports suggested that hypertrophic cardiomyopathy was a rare disorder that was nearly always associated with the need for surgery to relieve obstruction [heart.bmj.com]

Following neoadjuvant concurrent chemoradiation treatment, the patient underwent left lower lobectomy and mediastinal lymphadencetomy. [kjim.org]

Prognosis
The long-term prognosis is excellent. [ncbi.nlm.nih.gov]
Results LV obstruction and prognosis Of the 526 study patients, 141 (27%) had LV obstruction. [onlinejacc.org]
Untreated, this subset of patients has a poor prognosis, with one study reporting more than 50 percent to worsen symptomatically and 11 percent dying by four- year follow-up. [advances-in-medicine.net]
Patients who presented exercise-induced DLVOTO in our series had a good prognosis at mid-term, as no events were observed after a mean follow-up of one year. [revespcardiol.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]

Epidemiology
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]
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]
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]
Introduction Often hereditary (underlying pathophysiology is an excess of calcium channels ), hypertrophic cardiomyopathy leads to decreased LVEDV secondary to the hypertrophic heart (stroke volume, by contrast, remains normal). [openanesthesia.org]
Prevention
Thus, surgical techniques to reduce AML heights should be considered in patients with disproportionately large anterior leaflets in order to prevent SAM. Selection of size of the annuloplasty ring should take into consideration the height of the AML. [ncbi.nlm.nih.gov]
Antibiotic medications are prescribed to prevent bacterial endocarditis, a potentially life-threatening condition. [163.178.103.176]
