New breakthroughs in Gaoming Medical
Foshan Daily News reporter Chen Jiayi reports: Atrial fibrillation (AF) is the most common clinical arrhythmia and one of the few curable arrhythmias one. It can cause stroke, heart failure, and even death. Catheter ablation is the best treatment for patients with atrial fibrillation. Recently, under the guidance of Professor Liang Yuanhong of Guangdong Provincial People’s Hospital, the intervention team of the Cardiovascular Medicine Department of Gaoming District People’s Hospital successfully completed the first radiofrequency ablation of atrial fibrillation.
It is reported that in this case, the patient is a 54-year-old female who has been diagnosed with persistent atrial fibrillation for many years and complicated with cardiac insufficiency, which has caused serious trouble to daily life. According to the preliminary evaluation by the Department of Cardiovascular Medicine of the hospital, the patient has the indications for catheter radiofrequency ablation, and the patient is given regular anticoagulation therapy, and atrial fibrillation catheter ablation is recommended.
After the patient is readmitted to the hospital, the cardiovascular medical team will make a series of careful preparations for the patient’s surgical treatment, including preoperative preparation, preoperative and intraoperative medication, various instruments, and electrophysiological instruments used in the operation. installation, commissioning, and even the travel situation of the patient and the psychological state of the patient.
The operation officially started at 9:30 a.m. that day. After mapping, ablation and repeated verification, the patient’s atrial fibrillation was terminated. The operation was successfully completed in less than 2 hours. The patient had no complaints and returned to the ward. .
Atrial fibrillation is not a benign cardiac arrhythmia, and the risk of death is 2 times higher than that of those without atrial fibrillation. The most dangerous complication is cerebral embolism, which is 5 times higher than that of normal people. The number of new atrial fibrillation patients in my country is as high as 8 million every year. In the past, only anti-arrhythmic drugs or ventricular rate control could be used to improve patient symptoms. Now, catheter ablation of atrial fibrillation has been developed globally for more than 20 years and has become a milestone in the development of the cardiovascular field.
At present, domestically, catheter ablation is not only a hot spot in the treatment of atrial fibrillation, but also a difficulty in cardiac interventional technology. It has the advantages of one-time radical cure and no need for thoracotomy. The successful implementation of catheter ablation of atrial fibrillation in this case marks a solid step forward in the treatment of arrhythmia in the District People’s Hospital, and the level of interventional diagnosis and treatment in the Department of Cardiovascular Medicine has reached a new level.
Atrial Fibrillation Tips
1. What is Atrial Fibrillation?
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. The incidence of atrial fibrillation increases with age, reaching 10% of people over the age of 75. During atrial fibrillation, the frequency of atrial excitation is 300 to 600 beats/min, and the heart rate is often fast and irregular, sometimes reaching 100 to 160 beats/min. effective contraction. Atrial fibrillation is also closely related to diseases such as coronary heart disease, hypertension and heart failure.
2. What are the symptoms of atrial fibrillation?
Atrial fibrillation is a rapid and irregular heartbeat, and patients often experience palpitation, shortness of breath, chest pain, fatigue, decreased exercise capacity, dizziness, and syncope. Because of individual differences, some people experience no discomfort with atrial fibrillation, especially if the heart rate is slow or if the atrial fibrillation lasts for a long time. Because of this, atrial fibrillation is ignored by many patients, thus missing the best time for treatment.
3. What are the hazards of atrial fibrillation?
Atrial fibrillation has two main hazards: stroke and heart failure. Atrial fibrillation can easily lead to stroke: In atrial fibrillation, the blood in the atria cannot be fully pumped into the ventricle, and the stagnant blood can easily form a blood clot in the atrium. The thrombus breaks off and reaches the brain, blocking the blood vessels in the brain, causing an ischemic stroke. Long-term atrial fibrillation can increase the burden on the heart, eventually leading to heart failure and even death.
4. What is radiofrequency ablation?
Radiofrequency ablation of atrial fibrillation is a technique that uses radiofrequency energy at the tip of an intracardiac catheter to eliminate abnormal electrical activity in atrial tissue. The principle is to apply radio frequency current through the myocardial tissue to generate heat energy and conduct it to the deep tissue. Generally, at 50 °C, most of the myocardial tissue will form irreversible coagulation necrosis, and become a myocardial scar that will not conduct and trigger activity, so as to achieve Purpose of treatment of atrial fibrillation.
