Is Lvot life threatening?

Is Lvot life threatening?

The onset of LVOTO is largely unpredictable due to a complex interplay between preload, afterload, heart rhythm and rate in susceptible patients. The consequences of missing this treatable condition may lead to life-threatening hypotension refractory to, or exacerbated by, a further increase in inotropic support.

Can left ventricular hypertrophy be cured?

LVH can often be corrected by treating the underlying problem causing the heart to work too hard. Depending on the type of damage that has occurred, treatment measures may include medications and heart-healthy lifestyle changes to help reduce the pressure in the heart.

What causes left ventricular outflow obstruction?

Left ventricular outflow tract obstruction (LVOTO) is a recognised feature of hypertrophic cardiomyopathy. It is caused by the thickened heart muscle and the abnormal movement of the mitral valve. This is the main mechanism of debilitating symptoms in hypertrophic cardiomyopathy patients.

How is Lvot treated?

Symptomatic LVOT obstruction requires aggressive therapy, which is initially pharmacological intervention and more effectively septal myectomy, whether surgical or through alcohol ablation.

Why dobutamine is contraindicated in hypertrophic cardiomyopathy?

The use of dobutamine or arbutamine is contraindicated in patients with idiopathic hypertrophic subaortic stenosis (IHSS). Dobutamine or arbutamine may increase the pressure gradient within the left ventricle and thereby worsen cardiac output in patients with IHSS.

What is normal Lvot?

Mean LVOT area indexed to body surface area was 2.3 ± 0.5 cm(2)/m(2) in women and 2.6 ± 0.7 cm(2)/m(2) in men. LVOT area demonstrated significant correlation with aortic root diameter. Conclusions: The normal LVOT is ovoid in shape.

What is a high Lvot gradient?

LVOT obstruction is defined as a peak instantaneous gradient greater than or equal to 30 mm Hg. A gradient greater than or equal to 50 mm Hg is generally recognized as the threshold at which LVOT obstruction becomes hemodynamically significant.

What is Echo Lvot?

Left ventricular outflow tract velocity time integral (LVOT VTI) is a measure of cardiac systolic function and cardiac output. Heart failure patients with low cardiac output are known to have poor cardiovascular outcomes.

Is Lvot obstruction serious?

In conclusion, the development of a LVOT obstruction during acute anterior myocardial infarction has to be considered a serious and potentially fatal complication.

What are the treatment options for LVOT obstruction in heart failure?

The pharmacological treatment of LVOT obstruction and related symptoms in HCM patients is based on a time-honoured combination of negative inotropic agents, including β-blockers, calcium antagonists, and disopyramide.

What is left ventricular outflow tract (LVOT) obstruction?

Left ventricular outflow tract obstructions (LVOTOs) encompass a series of stenotic lesions starting in the anatomic left ventricular outflow tract (LVOT) and stretching to the descending portion of the aortic arch ( Figure 1 ). Obstruction may be subvalvar, valvar, or supravalvar.

How many patients have had surgery for LVOT obstruction?

Forty-five patients underwent surgery to relieve LVOT obstruction, of which 52% needed an additional nonmyectomy (MV repair/replacement or PM reorientation) approach.

What does LVOT stand for?

In addition, dynamic LV outflow tract (LVOT) obstruction is present in approximately 70% of HCM patients, either at rest or with physiological provocation.
