Senior people with heavy calcium deposits on their heart's aortic valve, also known as aortic stenosis (AS) are considered too high risk for valve replacement surgery. AS develops when the aortic valve (it is located between the left chamber of the ticker and the aorta which is the main artery delivering blood from the ticker to the body) doesn't open properly or gets narrowed, which causes the ticker to work harder to pump required quantity of blood into the aorta, which in turn, can lead to thickening and enlargement of the ticker eventually leading to heart failure (HF). Fainting, irregular heartbeat, shortness of breath, fatigue, swelling of ankle and knee, dizziness and heart murmur are some symptoms of AS. For patients considered too high risk for valve replacement surgery, transcatheter aortic valve replacement (TAVR) is a great option (a minimally invasive procedure) that involves insertion of an aortic valve within a damaged valve through a catheter, which th...

The word “ventricular” refers to the lower chambers of your ticker, whereas tachycardia is the medical term for a fast heart rate, and that’s what ventricular tachycardia is in a nutshell- an abnormally rapid heartbeat. How Does The Ticker Function? Your ticker is a muscular pump made of four chambers- the two upper chambers are called the atria and the two lower ones are called the ventricles. They work together to pump nutrient-rich, oxygenated blood throughout the body. A healthy heart beats about 100,000 times every day. Electrical signals control your heartbeat, which follow a specific pattern, beginning in the sinoatrial, or SA, node, which is in your heart’s upper chamber, or atrium. Your atria contracts because of this signal, it then moves down to another part of your heart called the atrioventricular, or AV, node, which tells your ventricles to contract. Ventricular Tachycardia - What happens with ventricular tachycardia (V-tach) is that the electrical signals...

Hypertrophic Cardiomyopathy (HCM): HCM is a common cause of sudden cardiac arrest (SCA) in young people, especially young athletes. It is very common and can affect anyone regardless of age. When heart muscle cells enlarge and cause the walls of the ventricles (generally the left ventricle) to thicken, what results is Hypertrophic Cardiomyopathy . It is an inherited disease of your heart muscle, where the muscle wall of your ticker becomes thickened. Although the ventricle size often remains normal, but the thickening may block blood flow out of the ventricle, this condition (if happens) is called obstructive hypertrophic cardiomyopathy. The septum (wall that divides the left and right side of the ticker) sometimes thickens and bulges into the left ventricle which can block blood flow out of the ventricle causing the ventricle to work hard to pump blood. Chest pain, dizziness, shortness of breath, or fainting are some of the symptoms. HCM also can affect the mitral valve of the...
