He had a history of atrial fibrillation as well as heart failure, and reported that he had recently experienced a thumping heartbeat, accompanied by chest tightness after activity. After relevant examinations, it was clear that the patient had permanent atrial fibrillation. After informing the patient of his condition, it was agreed to perform circumflex pulmonary vein electrical isolation for the treatment of atrial fibrillation, followed by oral medication to alleviate the symptoms. After the operation, the patient recovered well and his discomfort gradually disappeared, and he was discharged from the hospital. Basic information] Male, 66 years old [Type of disease] Permanent atrial fibrillation [Hospital] The First Affiliated Hospital of Xi’an Jiaotong University [Date of consultation] May 2020 [Treatment plan] Surgical treatment (circumflex pulmonary vein isolation) + intravenous drip (lidocaine hydrochloride injection, heparin sodium injection) + oral medication (amiodarone hydrochloride tablets, furosemide tablets) [Treatment cycle] Hospitalization for 5 days, followed by review in 2 weeks. Treatment effect] Panic and chest tightness disappeared and the condition was stabilized I. Initial Consultation When we first saw the patient, he was in poor mental state, with one hand pressing on the chest and open-mouth respiration, and his face and limbs were mildly swollen. He reported that he had atrial fibrillation and mild heart failure in the past, but had not been treated systematically. Recently, the symptoms of chest tightness and panic attacks have been worsening, especially after activity. I initially considered atrial fibrillation, and after obtaining the patient’s consent, I performed a general examination, which showed a heart rate of 75 beats/min, pulse of 66 beats/min, arrhythmia, and respiration of 25 beats/min; there was no pathologic murmur detected in the valves on cardiac auscultation. An ambulatory electrocardiogram was performed that clearly suggested atrial fibrillation. He was initially diagnosed with permanent atrial fibrillation and was admitted to the hospital for treatment. After the patient was admitted to the hospital, relevant examinations were carried out to exclude contraindications, and the circumflex pulmonary vein electric isolation operation was performed after communication with the patient. After signing the surgical consent form, the patient was given intravenous lidocaine hydrochloride injection for local anesthesia, and the coronary sinus electrode catheter was implanted through the patient’s right jugular vein, and the septum was punctured through the right femoral vein, and two long sheaths were implanted in the atrium, and the electrical recovery was sinus rhythm during the operation, and the repeated stimulation did not lead to the recurrence of atrial fibrillation. Postoperatively, the patient was given symptomatic treatment, anticoagulant drug rivaroxaban tablets were given to prevent thrombosis, amiodarone hydrochloride tablets were prescribed to control the ventricular rate, furosemide tablets and spironolactone tablets were prescribed to diuretically reduce swelling. Third, therapeutic effect After surgical treatment, the patient’s symptoms of atrial fibrillation obviously disappeared, and the measured heart rate of 79 beats/minute and respiration of 22 beats/minute were obviously better than the preoperative state, and the electrocardiogram examination showed sinus rhythm, with no obvious abnormality. The patient took oral medication regularly, and the symptoms of facial as well as limb edema disappeared, and the symptoms improved significantly compared with the previous ones. The patient was discharged from the hospital for convalescence, and continued to take the above medications as prescribed by the doctor outside the hospital, and returned to the hospital for review of electrocardiogram and cardiac ultrasound after 2 weeks, and review of CT of lungs after 2 months. After systematic treatment and seeing the patient’s disease gradually improving, I am sincerely happy for him and suggest that the patient should pay attention to the following matters after discharge: 1. Take oral medication regularly and do not stop or reduce or increase the dosage on your own, so as not to cause other uncomfortable symptoms; 2. Because diuretic drugs can promote the excretion of water in the body, the patient should be examined by a doctor regularly for potassium during the period of using the medication to avoid hypokalemia or hyperkalemia; 3. Hypokalemia or hyperkalemia; 3. At least 3-4 outpatient follow-up visits should be made within 1 year to avoid recurrence of atrial fibrillation. The patient should maintain a relaxed mood in daily life and avoid large fluctuations in mood to avoid recurrence of the disease. Because the patient had good physical quality and no other organ diseases, the postoperative recovery is faster and the prognosis is better. However, if the patient is found to have atrial fibrillation and a history of heart failure at an early stage and is treated in time, the early surgery may be able to control the symptoms well, thus reducing the patient’s pain and the degree of the disease. Therefore, if you experience rapid heartbeat, chest tightness, panic attacks, or fatigue without any cause, and if the symptoms are not relieved after resting or last for a long time, it is recommended that you consult a cardiovascular surgeon in a timely manner in order to avoid delays in your condition.
