What is Hypertrophic Cardiomyopathy?

Understanding Hypertrophic Cardiomyopathy (HCM)

What Happens if

HCM is Untreated?

What Happens if HCM is Left Untreated?
When HCM is not properly managed, the thickened heart muscle places an additional burden on the heart, making it harder to pump blood effectively. Over time, this can lead to more severe problems, such as arrhythmias (irregular heartbeats) or heart failure, causing the heart to struggle to meet the body's demand for blood. In some cases, untreated HCM also increases the risk of sudden cardiac death, particularly in young individuals. Therefore, early diagnosis and treatment are crucial for preventing these serious outcomes.

Impact of HCM on Quality of Life
What is the Wei Procedure and Vass M1?
The Wei Procedure (TransApical Beating-heart Septal Myectomy) is a minimally invasive surgery designed to treat hypertrophic cardiomyopathy (HCM).

During the procedure, the surgeon accesses the heart through a small incision in the chest and uses specialized instruments to remove a portion of the thickened heart muscle that is obstructing blood flow. The Vass M1 device is then used to assist in reshaping the heart's septum

It is a minimally-invasive alternative to traditional open-heart surgery. Unlike conventional procedures, Vass M1 is inserted through a small incision without opening the chest.

    The device is compact and allows for precise reshaping of the heart's septum.

    Most patients experience a rapid improvement in HCM symptoms after the procedure, with significant enhancements in heart function and quality of life.
