What is 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.

What causes Lvot obstruction?

Hypertrophic cardiomyopathy (HCM) is the most common cause of dynamic left ventricular outflow tract (LVOT) obstruction. The hypertrophy of the basal septum and systolic anterior motion of the mitral valve leaflet (SAM) cause a dynamic obstruction in the LVOT1-3).

What is the ICD 10 code for hypertrophic obstructive cardiomyopathy?

Obstructive hypertrophic cardiomyopathy I42. 1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

What is significant Lvoto?

Dynamic left ventricular outflow tract obstruction (LVOTO) can be hemodynamically significant and can adversely affect the heart and quality of life. It is caused by systolic anterior motion (SAM) of the anterior mitral valve into the LVOT. The mechanism underlying SAM has been an area of special interest.

How long does a septal myectomy surgery take?

The actual surgery lasts from 3 to 6 hours, however your family should expect additional time before and after surgery.

What is ventricular inflow obstruction?

Summary. In this chapter, obstructions to left heart inflow are considered in three broad categories: pulmonary vein obstruction, left atrial-level obstruction (cor triatriatum and supravalvar mitral ring), and left ventricular (LV) inflow obstruction (mitral stenosis and hypoplasia).

What does ventricular outflow obstruction mean?

A ventricular outflow tract obstruction is one type of congenital heart defect in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders.

What is the ICD 10 code for small bowel obstruction?

Other intestinal obstruction. K56.69 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. This is the American ICD-10-CM version of K56.69. Other international versions of ICD-10 K56.69 may differ.

What is the ICD 9 code for left ventricular failure?

Heart failure is classified to ICD-9-CM category 428, and the following are the specific code assignments: • 428.0, CHF that includes right heart failure secondary to left heart failure; • 428.1, Left heart failure (includes left ventricular failure); • 428.20, Unspecified systolic heart failure;
