LV Aneurysms usually after effects of myocardial infarctions. When the heart muscle partially dies during the heart attack, a layer of muscle may survive and be severely weakened and start to become an aneurysm. The blood may flow into the surrounding dead muscles and inflate the weakened flap of muscle into trouble.
It's one of the many complications that may occur after a heart attack (Myocardial Infarction). They usually arise from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. This, in turn, blocks the passageways leading out of the heart, leading severely constricted blood flow to the body. It can be fatal and usually non-rapturing because they are lined by scar tissue.
Eligible for LV Aneurysm Surgery
Not all patient with heart failure is needed for this procedure. Patients who may benefit from left ventricular surgery include:
- Have had a heart attack that resulted in an aneurysm or a scar in the left ventricle and has symptoms of heart failure (such as shortness of breath, fatigue, swelling, and others) that are not relieved with medications and lifestyle changes
- Have severe coronary artery disease with symptoms of angina
- Have valve problems that require surgical treatment
- Ventricular tachycardia (abnormal rhythm originating in the left ventricle that makes it beat too quickly). Indication include passing out, feeling lightheaded or feeling a rapid pounding of the chest
- Carotid Endarterectomy:
It's a type of surgery that used to prevent strokes in people who have carotid artery disease. It occurs if plaque builds up in the two large arteries on each side of your neck (the carotid arteries). The carotid arteries supply your brain with oxygen-rich blood.
Plaque is made up of fat, cholesterol, calcium and other substances found in the blood. Over the time the plaque got hardens and narrows the carotid arteries. This limits or blocks the flow of Oxygen-rich blood to your brain which leads to a stroke.
A stroke also can occur if the plaque in a carotid artery cracks or ruptures (bursts). Blood cell fragments called platelets stick to the site of the injury and may clump together to form blood clots. Blood clots can partly or fully block a carotid artery.
A stroke also can occur if the plaque in a carotid artery cracks or ruptures (bursts). Blood cell fragments called platelets stick to the site of the injury and may clump together to form blood clots. Blood clots can partly or fully block a carotid artery.
A piece of plaque or a blood clot also can break away from the wall of the carotid artery. The plaque or clot can travel through the bloodstream and get stuck in one of the brain's smaller arteries. This can block blood flow in the artery and cause a stroke.
In the Carotid Endarterectomy, you receive a general anesthetic. Then we make small incision along the front of your neck, open your carotid artery and removes the plaques that are clogging your artery. We then repair the artery with stitches or patch made with vein or artifical material (patch graft).
We recommend carotid endarterectomy if you have more than 60 percent of blockage in your arteries. You may be experiencing symptoms. We will evaluate your condition and determine whether you're the right candidate for carotid Endarterectomy.
