Recanalization of the basilar artery is key to the successful treatment of basilar artery thrombosis and to improving its prognosis.
Full Answer
What are the treatment options for basilar artery occlusion?
Ideally, patients with basilar artery occlusion should be treated within the context of a randomized trial. In the absence of this option, many stroke experts would advocate the use of embolectomy or intra-arterial thrombolysis.
What causes perfusion defect of the basal membranous septum and basal inferior wall?
Normal thinning of the basal membranous septum and basal inferior wall causes perfusion defect in the corresponding segments.
How effective is recanalization for acute basilar artery occlusion?
In a meta-analysis, recanalization of acute basilar artery occlusion led to reduction in mortality by 2-fold and reduction in the risk of DoD by 1.5-fold. With recanalization, risk ratios (RR) for death or dependency (DoD) in those treated within 12 hours was 0.63; and for those treated after 12 hours, 0.67.
Is the lateral wall of the ventricle involved in perfusion defects?
The lateral wall of the ventricle was not involved. Perfusion defects at rest were frequently associated with reduced regional wall thickening and wall motion and reduced right ventricular systolic function.
What is a reversible perfusion defect in the heart?
The degree of reversibility of a perfusion defect is identified on post-stress images as an area of decreased radiopharmaceutical activity that improves or disappears on rest or redistribution images. Non-reversible defect (fixed) shows no significant changes in activity between post-stress or rest images.
What does a perfusion defect mean?
Areas that are damaged or don't have good blood flow do not absorb the tracer. The damaged areas may be called “cold spots” or “defects.” A stress myocardial perfusion scan assesses blood flow to the heart muscle when it is stressed. The heart is usually “stressed” from exercise.
How is inferior ischemia treated?
Treatment for myocardial ischemia involves improving blood flow to the heart muscle. Treatment may include medications, a procedure to open blocked arteries (angioplasty) or bypass surgery. Making heart-healthy lifestyle choices is important in treating and preventing myocardial ischemia.
Can ischemia be cured?
Ischemia may be reversible, in which case the affected tissue will recover with the restoration of blood flow, or irreversible, which can result in tissue death.
What is the next step after an abnormal stress test?
If your stress test results suggest that you might have coronary artery disease or show an arrhythmia, your doctor will use the information to develop a treatment plan. You may need additional tests, such as a coronary angiogram.
What causes perfusion defect?
Conclusions: Perfusion defects are associated with an increase in pulmonary artery pressure (PAP) and functional limitation. Age, longer times between symptom onset and diagnosis, initial pulmonary vascular obstruction and previous venous thromboembolism were associated with perfusion defects.
Can ischemic heart disease be cured?
Coronary heart disease cannot be cured but treatment can help manage the symptoms and reduce the chances of problems such as heart attacks. Treatment can include: lifestyle changes, such as regular exercise and stopping smoking.
Can you reverse ischemia?
"You can't cure heart disease, but you can slow its progression.” Ornish agrees that if you're just trying to slow heart disease, you might have more freedom with your diet.
How long can you live with myocardial ischemia?
About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
How is ischemic heart disease treated?
Lifestyle changes, medications, and sometimes surgery can successfully treat ischemic heart disease. You can reduce your risk of this disease by following heart-healthy practices. This includes eating a low-fat, low-sodium diet, being physically active, not smoking, and maintaining a moderate body weight.
How can I increase blood flow to my heart?
What You Can Do To Boost Your CirculationIncrease cardiovascular exercise. ... If you smoke, quit. ... Drink black or green tea. ... If you are anemic, take iron supplements or eat iron-rich food. ... Dry brush your body. ... Decrease stress. ... Include more omega-3 fatty acids in your diet. ... Wear compression socks and elevate your legs.
How do you improve ischemia?
The goal of myocardial ischemia treatment is to improve blood flow to the heart muscle....Medications to treat myocardial ischemia include:Aspirin. ... Nitrates. ... Beta blockers. ... Calcium channel blockers. ... Cholesterol-lowering medications. ... Angiotensin-converting enzyme (ACE) inhibitors. ... Ranolazine (Ranexa).
Abstract
Background Patients with systemic ventricles of right ventricular morphology are at high risk of contractile dysfunction, the cause of which has not been fully elucidated.
Patients and methods
Five patients (three male and two female aged from 3.5 to 34 years) with congenitally corrected TGA and without associated structural cardiac defects were studied (table 1 ).
Results
Table 1 lists details of individual exercise tests and functional assessments. The results of right ventricular perfusion are described below (table 2 ).
Discussion
Although some patients with congenitally corrected TGA may lead normal lives without evidence of cardiac decompensation, 2 , 7 many develop right ventricular failure. 3 , 4 , 17 This may result in symptoms of congestive cardiac failure, decreased functional capacity, and early death.

What percentage of MIs involve the inferior wall?
Approximately 40% of all MIs involve the inferior wall. Traditionally, inferior MIs have a better prognosis than those in other regions, such as the anterior wall of the heart. The mortality rate of an inferior wall MI is less than 10%.
Which artery supplies the inferior myocardium?
In most patients, the inferior myocardium is supplied by the right coronary artery. In about 6-10% of the population, because of left dominance, the left circumflex will supply the posterior descending coronary artery. Approximately 40% of all MIs involve the inferior wall.
What is the procedure called when a balloon is inserted into the narrowed area of the artery?
Angioplasty and stenting. A long, thin tube (catheter) is inserted into the narrowed part of your artery. A wire with a tiny balloon is threaded into the narrowed area and inflated to widen the artery. A small wire mesh coil (stent) is usually inserted to keep the artery open. Coronary artery bypass surgery.
What is the best medicine for myocardial ischemia?
The low blood flow decreases the amount of oxygen your heart muscle receives. Medications to treat myocardial ischemia include: Aspirin. A daily aspirin or other blood thinner can reduce your risk of blood clots, which might help prevent obstruction of your coronary arteries.
What is the best medication for high blood pressure?
Angiotensin-converting enzyme (ACE) inhibitors. These medications help relax blood vessels and lower blood pressure. Your doctor might recommend an ACE inhibitor if you have high blood pressure or diabetes in addition to myocardial ischemia. Ranolazine (Ranexa).
What is the difference between anterolateral and lateral?
Antero- refers to the anterior, or front side of something. -lateral means to the side or the outside of something. So to put it all together Anterolateral Ischemia means that there is or was a reduction of blood flow to the front outside part (of an organ).
Which artery supplies the inferolateral wall of the heart?
The infero-lateral wall of the heart is supplied either by the left anterior descending coronary artery or the left circumflex artery. What is urgently needed for this patient is a coronary arteriogram, which shows where the blockage or narrowed area of the coronary artery is.
Does cardio help with ischemia?
Consistent cardio can have plenty of protective qualities, especially against ischemia. If you have conditions like high cholesterol, high blood pressure, diabetes etc, it can increase the chances of ischemia if left unchecked. Proper exercise and medication can help attenuate the chances of ischemia.
Does Ranolazine help with angina?
This medication helps relax your coronary arteries to ease angina. Ranolazine may be prescribed with other angina medications, such as calcium channel blockers, beta blockers or nitrates. Procedures to improve blood flow. Sometimes, more-aggressive treatment is needed to improve blood flow.
