Heart attacks can produce similar symptoms to heart valve leaks. In addition, a leaky heart valve can cause a heart attack. If you are unsure whether or not you are having a heart attack, you should call emergency medical responders to be safe. Heart attack symptoms include:  Chest pain or pressure Pain that travels to your neck, jaw, down the arm, or back Feeling that you will vomit Abdominal discomfort, especially in the upper central (epigastric) region Heartburn or indigestion Shortness of breath Sweating Exhaustion Lightheadedness or dizziness This valve is the one that leaks most frequently. In this condition, when the left ventricle contracts, blood travels both into the aorta and back into the chamber it came from (the atrium).  This can increase the amount of blood in the left atrium, create more pressure in the pulmonary veins, and produce fluid build-up in the lungs. If your condition is mild, you may not notice any symptoms. If your condition is severe, you may experience:  Heart palpitations when you lie on your left side Shortness of breath Coughing Chest congestion Fluid buildup in your feet and ankles Dizziness Chest pain Heart failure When the left ventricle relaxes, blood is supposed to travel out of the heart into the aorta. But if the valve leaks, it also returns to the left ventricle. This can increase the amount of blood in the left ventricle, causing it to thicken and pump less efficiently. The walls of the aorta may also develop weak areas that may swell. Aortic valve regurgitation can be a congenital condition or be caused by high blood pressure, an infection, or injury to the valve. Symptoms include:  A heart murmur when the left ventricle relaxes Heart palpitations Heart failure Blood travels through the pulmonary valve as it goes from the heart to the lungs. If the valve leaks, some blood returns to the heart instead of going to the lungs. This condition is rare, but can be caused by congenital heart problems, high blood pressure, rheumatic fever, or a heart infection. Not everyone...
