Removal of tissue by vaporization, abrasion, or destruction. Methods used include heating tissue by hot liquids or microwave thermal heating, freezing (CRYOABLATION), chemical ablation, and photoablation with LASERS.
Procedures used for the targeted destruction of the mucous membrane lining of the uterine cavity.
Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
Excessive uterine bleeding during MENSTRUATION.
The veins that return the oxygenated blood from the lungs to the left atrium of the heart.
Procedures using an electrically heated wire or scalpel to treat hemorrhage (e.g., bleeding ulcers) and to ablate tumors, mucosal lesions, and refractory arrhythmias. It is different from ELECTROSURGERY which is used more for cutting tissue than destroying and in which the patient is part of the electric circuit.
The use of freezing as a special surgical technique to destroy or excise tissue.
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
That portion of the electromagnetic spectrum from the UHF (ultrahigh frequency) radio waves and extending into the INFRARED RAYS frequencies.
The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.

Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.
Tumors or cancer of the LIVER.
The use of focused, high-frequency sound waves to destroy tissue. It is sometimes used in conjunction with but is distinct from INTERVENTIONAL ULTRASONOGRAPHY.
Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.
Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in Wolff-Parkinson-White syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel. (Braunwald, Heart Disease, 4th ed)
A generic expression for any tachycardia that originates above the BUNDLE OF HIS.
An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.
The chambers of the heart, to which the BLOOD returns from the circulation.
A small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus. It gives rise to the atrioventricular bundle of the conduction system of the heart.
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.

Non-thermal ablation of rabbit liver VX2 tumor by pulsed high intensity focused ultrasound with ultrasound contrast agent: Pathological characteristics. (4/191)

AIM: To investigate the pathological characteristics of non-thermal damage induced by pulsed high intensity focused ultrasound (PHIFU) combined with ultrasound contrast agent (UCA), SonoVue (Bracco SpA, Milan, Italy) in rabbit liver VX2 tumor. METHODS: Liver VX2 tumor models were established in 20 rabbits, which were divided randomly into PHIFU combined with ultrasound contrast agent group (PHIFU + UCA group) and sham group. In the PHIFU + UCA group, 0.2 mL of SonoVue was injected intravenously into the tumor, followed by ultrasound exposure of I(SP) 5900 W/cm(2). The rabbits were sacrificed one day after ultrasound exposure. Specimens of the exposed tumor tissues were obtained and observed pathologically under light microscope and transmission electron microscope. The remaining tumor tissues were sent for 2,3,5-Triphenyltetrazolium chloride (TTC) staining. RESULTS: Before TTC staining, tumor tissues in both the sham and the PHIFU + UCA groups resembled gray fish meat. After TTC staining, the tumor tissues were uniformly stained red, with a clear boundary between tumor tissue and normal tissue. Histological examination showed signs of tumor cell injury in PHIFU + UCA group, with cytoplasmic vacuoles of various sizes, chromatin margination and karyopyknosis. Electron microscopic examination revealed tumor cell volume reduction, karyopyknosis, chromatin margination, intercellular space widening, the presence of high electron-density apoptotic bodies and vacuoles in cytoplasm. CONCLUSION: The non-thermal effects of PHIFU combined with UCA can be used to ablate rabbit liver VX2 tumors.  (+info)

Causes of Menorrhagia

There are several potential causes of menorrhagia, including:

1. Hormonal imbalance: Hormonal changes can lead to an imbalance in the uterus, causing excessive bleeding.
2. Uterine fibroids: These noncancerous growths in the uterus can cause heavy bleeding during menstruation.
3. Adenomyosis: This condition occurs when tissue similar to the lining of the uterus grows into the muscle of the uterus, leading to heavy bleeding.
4. Endometrial polyps: These are growths that can develop on the lining of the uterus and cause heavy bleeding.
5. Thyroid disorders: Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can cause menorrhagia.
6. Pelvic inflammatory disease (PID): This is an infection of the reproductive organs that can cause scarring and lead to heavy bleeding.
7. IUDs: Intrauterine devices (IUDs) can cause heavy bleeding, especially during the first few months after insertion.
8. Medications: Certain medications such as anticoagulants and anti-inflammatory drugs can increase the risk of menorrhagia.
9. Bleeding disorders: Women with bleeding disorders, such as von Willebrand disease or platelet dysfunction, may experience heavy menstrual bleeding.
10. Cancer: In rare cases, menorrhagia can be a symptom of uterine cancer.

Symptoms of Menorrhagia

The primary symptom of menorrhagia is heavy menstrual bleeding that lasts for more than 7 days or bleeds that are heavier than usual. Other symptoms may include:

1. Soaking through sanitary products every hour or two
2. Using double sanitary products (e.g., a pad and a tampon) to control bleeding
3. Bleeding that lasts for more than 7 days
4. Menstrual blood clots larger than a quarter
5. Painful menstruation (dysmenorrhea)
6. Passing large blood clots during bowel movements or urination
7. Fatigue, dizziness, or fainting due to anemia
8. Weakness or shortness of breath

Diagnosis and Treatment of Menorrhagia

If you experience any of the symptoms of menorrhagia, it is important to see a healthcare provider for proper diagnosis and treatment. The healthcare provider will perform a physical examination and may order one or more of the following tests to determine the cause of heavy menstrual bleeding:

1. Complete Blood Count (CBC) to check for anemia and other blood abnormalities
2. Blood smear examination to look for abnormal cells or blood clotting disorders
3. Ultrasound to evaluate the uterus and ovaries
4. Endometrial biopsy to examine the lining of the uterus
5. Hysteroscopy to visualize the inside of the uterus
6. Laparoscopy to evaluate the pelvic organs

Treatment for menorrhagia depends on the underlying cause and may include:

1. Medications such as hormonal contraceptives, nonsteroidal anti-inflammatory drugs (NSAIDs), or iron supplements to control bleeding and anemia
2. Surgical procedures such as endometrial ablation or hysterectomy in severe cases that do not respond to other treatments
3. Lifestyle changes such as avoiding caffeine, alcohol, and spicy foods, as well as taking regular exercise and maintaining a healthy diet
4. Hormone replacement therapy (HRT) to regulate hormonal imbalances
5. Platelet transfusions or blood transfusions in cases of severe bleeding

It's important to note that menorrhagia can be a symptom of a more serious underlying condition, so it's essential to seek medical attention if you experience any of the following:

1. Prolonged or heavy menstrual bleeding (more than 7 days)
2. Bleeding between periods or after sex
3. Painful periods or difficulty using tampons
4. Fever, chills, or vomiting during menstruation
5. Unusual vaginal discharge or odor
6. Abdominal pain or bloating

Early diagnosis and treatment can help manage symptoms and prevent complications of menorrhagia, such as anemia, fatigue, and infertility.

There are several risk factors for developing AF, including:

1. Age: The risk of developing AF increases with age, with the majority of cases occurring in people over the age of 65.
2. Hypertension (high blood pressure): High blood pressure can damage the heart and increase the risk of developing AF.
3. Heart disease: People with heart disease, such as coronary artery disease or heart failure, are at higher risk of developing AF.
4. Diabetes mellitus: Diabetes can increase the risk of developing AF.
5. Sleep apnea: Sleep apnea can increase the risk of developing AF.
6. Certain medications: Certain medications, such as thyroid medications and asthma medications, can increase the risk of developing AF.
7. Alcohol consumption: Excessive alcohol consumption has been linked to an increased risk of developing AF.
8. Smoking: Smoking is a risk factor for many cardiovascular conditions, including AF.
9. Obesity: Obesity is a risk factor for many cardiovascular conditions, including AF.

Symptoms of AF can include:

1. Palpitations (rapid or irregular heartbeat)
2. Shortness of breath
3. Fatigue
4. Dizziness or lightheadedness
5. Chest pain or discomfort

AF can be diagnosed with the help of several tests, including:

1. Electrocardiogram (ECG): This is a non-invasive test that measures the electrical activity of the heart.
2. Holter monitor: This is a portable device that records the heart's rhythm over a 24-hour period.
3. Event monitor: This is a portable device that records the heart's rhythm over a longer period of time, usually 1-2 weeks.
4. Echocardiogram: This is an imaging test that uses sound waves to create pictures of the heart.
5. Cardiac MRI: This is an imaging test that uses magnetic fields and radio waves to create detailed pictures of the heart.

Treatment for AF depends on the underlying cause and may include medications, such as:

1. Beta blockers: These medications slow the heart rate and reduce the force of the heart's contractions.
2. Antiarrhythmics: These medications help regulate the heart's rhythm.
3. Blood thinners: These medications prevent blood clots from forming and can help reduce the risk of stroke.
4. Calcium channel blockers: These medications slow the entry of calcium into the heart muscle cells, which can help slow the heart rate and reduce the force of the heart's contractions.

In some cases, catheter ablation may be recommended to destroy the abnormal electrical pathway causing AF. This is a minimally invasive procedure that involves inserting a catheter through a vein in the leg and guiding it to the heart using x-ray imaging. Once the catheter is in place, energy is applied to the abnormal electrical pathway to destroy it and restore a normal heart rhythm.

It's important to note that AF can increase the risk of stroke, so anticoagulation therapy may be recommended to reduce this risk. This can include medications such as warfarin or aspirin, or in some cases, implantable devices such as a left atrial appendage closure device.

In conclusion, atrial fibrillation is a common heart rhythm disorder that can increase the risk of stroke and heart failure. Treatment options depend on the underlying cause and may include medications, cardioversion, catheter ablation, or anticoagulation therapy. It's important to work closely with a healthcare provider to determine the best course of treatment for AF.

Liver neoplasms, also known as liver tumors or hepatic tumors, are abnormal growths of tissue in the liver. These growths can be benign (non-cancerous) or malignant (cancerous). Malignant liver tumors can be primary, meaning they originate in the liver, or metastatic, meaning they spread to the liver from another part of the body.

There are several types of liver neoplasms, including:

1. Hepatocellular carcinoma (HCC): This is the most common type of primary liver cancer and arises from the main cells of the liver (hepatocytes). HCC is often associated with cirrhosis and can be caused by viral hepatitis or alcohol abuse.
2. Cholangiocarcinoma: This type of cancer arises from the cells lining the bile ducts within the liver (cholangiocytes). Cholangiocarcinoma is rare and often diagnosed at an advanced stage.
3. Hemangiosarcoma: This is a rare type of cancer that originates in the blood vessels of the liver. It is most commonly seen in dogs but can also occur in humans.
4. Fibromas: These are benign tumors that arise from the connective tissue of the liver (fibrocytes). Fibromas are usually small and do not spread to other parts of the body.
5. Adenomas: These are benign tumors that arise from the glandular cells of the liver (hepatocytes). Adenomas are usually small and do not spread to other parts of the body.

The symptoms of liver neoplasms vary depending on their size, location, and whether they are benign or malignant. Common symptoms include abdominal pain, fatigue, weight loss, and jaundice (yellowing of the skin and eyes). Diagnosis is typically made through a combination of imaging tests such as CT scans, MRI scans, and ultrasound, and a biopsy to confirm the presence of cancer cells.

Treatment options for liver neoplasms depend on the type, size, location, and stage of the tumor, as well as the patient's overall health. Surgery may be an option for some patients with small, localized tumors, while others may require chemotherapy or radiation therapy to shrink the tumor before surgery can be performed. In some cases, liver transplantation may be necessary.

Prognosis for liver neoplasms varies depending on the type and stage of the cancer. In general, early detection and treatment improve the prognosis, while advanced-stage disease is associated with a poorer prognosis.

The symptoms of AVNRT may include palpitations, shortness of breath, chest pain, and dizziness or lightheadedness. The arrhythmia can be triggered by stress, caffeine, exercise, or certain medications. It is important to seek medical attention if these symptoms persist or worsen over time, as AVNRT can increase the risk of more serious complications such as stroke or heart failure.

Diagnosis of AVNRT typically involves a physical examination, electrocardiogram (ECG), and other diagnostic tests such as echocardiography or stress testing. Treatment options for AVNRT include medications to regulate the heart rhythm, cardioversion, catheter ablation, or implantation of a cardioverter-defibrillator (ICD).

In summary, Tachycardia, Atrioventricular Nodal Reentry (AVNRT) is an arrhythmia that originates in the AV node and causes an abnormal and rapid heart rate. It can be triggered by various factors and can lead to more serious complications if left untreated. Accurate diagnosis and appropriate treatment are essential to managing this condition and preventing potential complications.

There are several types of SVT, including:

1. Paroxysmal SVT: This type of SVT comes and goes on its own and may be triggered by certain activities or stimuli.
2. Persistent SVT: This type of SVT lasts for more than 24 hours and may require treatment to return the heart to a normal rhythm.
3. Permanent SVT: This type of SVT is ongoing and may require long-term treatment.

Symptoms of SVT may include:

* Rapid or fluttering heartbeat
* Palpitations
* Shortness of breath
* Dizziness or lightheadedness
* Chest pain or discomfort

SVT is caused by a variety of factors, including:

* Abnormal electrical pathways in the heart
* Increased activity of the sympathetic nervous system
* Certain medications
* Caffeine and other stimulants
* Thyroid problems

Treatment for SVT may include:

* Medications to slow the heart rate or regulate the heart rhythm
* Cardioversion, which is a procedure that uses electrical shock to return the heart to a normal rhythm
* Catheter ablation, which is a procedure that destroys the abnormal electrical pathways in the heart
* Implantable devices such as pacemakers or implantable cardioverter-defibrillators (ICDs)

It is important to seek medical attention if you experience any symptoms of SVT, as it can lead to more serious complications such as atrial fibrillation or stroke if left untreated.
