The gradient between LV apex and LV inflow was 25.9±18.5 mm Hg (>30 mm Hg in 27%), LV apex and aorta 39.2±29.4 mm Hg (>30 mm Hg in 58%), and LV inflow and aorta 9 (interquartile range [IQR] 7, 24) mm Hg (>30 . Of the 1101 consecutive patients, 273 (25 percent) had obstruction of left ventricular outflow under basal (resting) conditions with a peak instantaneous gradient of . An LVOT gradient greater than 30 mmHg marks the diagnosis of obstructive HCM and carries an increased risk of sudden cardiac death. 2 For this reason, extensive . Left ventricular outflow tract obstruction (LVOTO) occurs from not only obstructive hypertrophic cardiomyopathy but also other conditions such as sigmoid septum or post mitral valve repair. However, .
A left ventricular outflow tract pressure gradient (LVOT PG) ≥50 mmHg at rest in hypertrophic cardiomyopathy (HCM) is a predictor of heart failure and cardiovascular death [1, 2]. The clinical indication for myectomy and alcohol septal ablation is also LVOT PG ≥50 mmHg at rest or with physiological exercise [3].lv gradientLV Gradient Bracelet. 370,00€. Item unavailable. The LV Gradient Bracelet unites contrasting textures and color pairings in a style that adds visual interest to everyday accessorizing. The Monogram canvas, featuring the House's signature Monogram Flowers, appears in Spring-Summer 2025, here in a double-loop strap. A TTE allows the best Doppler angle line up to assess the LVOT gradient. A TOE may be required if there the patient has poor transthoracic windows or if a sub-valvular membrane is suspected. Echocardiography findings may include: Reduced LV end-diastolic diameter (< 2.2 cm/m 2) Increased basal septal wall thickness (>1.2 cm)
LVOTO is caused by fast-flowing blood through the LV outflow tract which pulls the mitral valve anteriorly (towards the LV outflow tract) due to a Venturi effect. This is known as systolic anterior motion (SAM) of the mitral valve.
Hemodynamically, LVOTO has been defined as a peak instantaneous gradient at LV outflow of at least 30 mmHg, either at rest or on provocation. While traditionally defined in patients with hypertrophic cardiomyopathy, LVOTO is known to have several causes. 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.

An LVOT gradient greater than 30 mmHg marks the diagnosis of obstructive HCM and carries an increased risk of sudden cardiac death. 2 For this reason, extensive pulsed Doppler interrogation of the LVOT gradient in the apical views is essential to identify any significant gradients.
Left ventricular outflow tract obstruction (LVOTO) occurs from not only obstructive hypertrophic cardiomyopathy but also other conditions such as sigmoid septum or post mitral valve repair. However, the changes of the LVOT pressure gradient (LVOT PG) in LVOTO with various conditions remain unclear.
A left ventricular outflow tract pressure gradient (LVOT PG) ≥50 mmHg at rest in hypertrophic cardiomyopathy (HCM) is a predictor of heart failure and cardiovascular death [1, 2]. The clinical indication for myectomy and alcohol septal ablation is also LVOT PG ≥50 mmHg at rest or with physiological exercise [3].
