The diagnosis of left ventricular outflow tract obstruction is usually made by echocardiographic assessment and is defined as a peak left ventricular outflow tract gradient of ≥ 30 mmHg. [37] Another, non-obstructive variant of HCM is apical hypertrophic cardiomyopathy (AHCM or ApHCM), [39] also called Yamaguchi syndrome.
A ventricular outflow tract obstruction is a heart condition in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders. Majority of these cases are congenital, but some are acquired throughout life. [1]
These patients had septal thickening, systolic anterior motion (SAM) of the mitral valve, left ventricular outflow tract (LVOT) obstruction with mean peak outflow gradients of 71 ±40mmHg. Compared with normal controls, the patients with SAM had longer anterior mitral leaflets, thicker septum (16 ±4 mm), and anterior displacement of the mitral ...
A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries. [1]The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity that connects to the pulmonary artery.
This is due to the decreased preload in this phase, worsening the obstruction and thus accentuating the murmur. [3] At the same time, the Valsalva maneuver (phase II) decreases the intensity of most other murmurs, including those resulting from aortic stenosis and atrial septal defect .

It’s the first film in the Captain America franchise to feature Anthony Mackie’s Sam Wilson in the title role, and Mackie’s star power is far below that of Reynolds or Jackman.
Pulsus bisferiens, also known as biphasic pulse, is an aortic waveform with two peaks per cardiac cycle, a small one followed by a strong and broad one. [1] It is a sign of problems with the aorta, including aortic stenosis and aortic regurgitation, as well as hypertrophic cardiomyopathy causing subaortic stenosis.
