Amyloid cardiomyopathy

Amyloid cardiomyopathy is a condition resulting in the death of part of the myocardium. It is associated with the systemic production and release of many amyloidogenic proteins, especially immunoglobulin light chain or transthyretin. It can be characterized by the extracellular deposition of amyloids, foldable proteins that stick together to build fibrils in the heart. The amyloid can be seen under polarized light in congo red stained biopsy.

Anisopoikilocytosis

Anisopoikilocytosis is a medical condition illustrated by a variance in size and shape of a red blood cell. The underlying cause can be attributed to various anemias, most often, beta thalassemia major, a form of microcytic anemia. In β thalassemia major the beta hemoglobin chain is completely absent, rendering an increase in fetal hemoglobin.

Arteriosclerotic heart disease

Arteriosclerotic heart disease, is a thickening and hardening of the walls of the coronary arteries. Atherosclerosis is a potentially serious condition where arteries become clogged with fatty substances called plaques, or atheroma.

Atrioventricular fistula

An atrioventricular fistula is a fistula between an atrium and a ventricle of the heart.
The formation of AVF is a potential complication of catheter ablation.

Bigeminal pulse

Bigeminal pulse is a medical condition, easily confused with pulsus alternans. Similar features between bigeminal pulse and pulsus alternans are strong peak and weak peak. However, unlike pulsus alternans, the weak beat in bigeminal pulse occurs prematurely. Thus, not followed a pause as it is in pulsus alternans but occurs close to normal strong beat.

Capillaritis

Capillaritis is where the capillaries, usually of the legs or lungs, are inflamed.
This can occur in the lungs, pulmonary capillary, deposits or in the skin like pigment Magenta dermatosis.
On her feet she begins as small brown dots and can cause pain. Mild capillaritis clears up within 3-4 months.

Intimal hyperplasia

Intimal hyperplasia is the thickening of the tunica intima of a blood vessel as a complication of a reconstruction procedure or endarterectomy. Intimal hyperplasia is the universal response of a vessel to injury and is an important reason of late bypass graft failure, particularly in vein and synthetic vascular grafts.

Intradural pseudoaneurysm

Intradural pseudoaneurysm is a broad term to describe several subtypes of aneurysms that fundamentally are different from the more typical intracranial berry-type aneurysms.

Ischemic monomelic neuropathy

Ischemic monomelic neuropathy is a rare, immediate, limb-threatening complication of hemodialysis access surgery.
Symptoms are acute pain in hand and forearm Muscle weakness. The main risk factors are the presence of diabetes and the creation of the brachial artery to vein fistula for vascular access. Operative treatment of the victim open with surgical ligation.

MBL deficiency

MBL deficiency is a pathology of the innate immune system involving Mannan-binding lectin pathway components such as MBL2.
It is believed that 5-10% of the population have an MBL deficiency of some degree. There are varying degrees of MBL deficiency, some people dont even know that they have a deficiency, while others may have such a low level that they suffer from infections with great frequency. Babies and young children are most at risk.

No reflow phenomenon

No reflow phenomenon is the failure of blood to reperfuse an ischemic area after the physical obstruction has been removed or bypassed.
This may be due to damage to the blood vessels of the microvasculature.

Phagocyte bactericidal dysfunction

Phagocyte bactericidal dysfunction refers to a class of medical conditions where phagocytes have a diminished ability to fight bacterial infection.
Examples include:
Hyperimmunoglobulin E syndrome. (Синдром Hyperimmunoglobulin е)
Chronic granulomatous disease. (Хроническая гранулематозная болезнь)
Chediak–Higashi syndrome. (Синдром Chediak–Хигасихиросимы)

Right atrial enlargement

Right atrial enlargement is a form of cardiomegaly. It can broadly be classified as either right atrial hypertrophy or dilation. Common causes include right ventricular failure, pulmonary hypertension, tricuspid regurgitation, tricuspid stenosis and atrial septal defect. It is characterized by a P wave height greater than 2.5 mm.
