What is radiofrequency ablation? It is a minimally invasive method using cardiac catheterization technology to treat various types of tachycardia. In particular, it has been widely used for the eradication of supraventricular tachycardia, and in this regard, it is a technique that involves a one-time cost (usually around$25,000), risking a single procedure, and obtaining a once-and-for-all cure. This technology has a history of more than 20 years and is now very mature. In hospitals with a large number of cases and experience, the success rate can be more than 99%, and the associated risks have been reduced to a very low level, for example, the complications of atrioventricular block requiring a permanent pacemaker are much lower than the one in two hundred that is generally believed. Domestic radiofrequency ablation is generally performed in the cardiac catheterization laboratory, mostly by specialized cardiologists. For adult patients, local anesthesia is generally used (general anesthesia is mostly used abroad, and pediatric patients sometimes need general anesthesia), and only a little anesthetic is administered near a few sites of puncture (subclavian vein, femoral vein, femoral artery, etc.), so that the patient’s consciousness is clear and he or she can communicate with the doctor at any time and tell how he or she feels. Step 1: After the puncture is completed, the physician delivers several very thin catheters to the patient’s heart to perform an induction test (sometimes with specific drugs) that can cause an on-the-spot attack of supraventricular tachycardia (the patient should not be afraid to have an attack, because the physician can terminate an on-the-spot attack of supraventricular tachycardia at any time with specific electrophysiological stimulation). This step is called “cardiac electrophysiological examination”, which allows to locate the location of the “extra wire” and to understand the characteristics of the patient’s electrical activity. It can be said that this step is the essential pre-work of “radiofrequency ablation”. In general, almost all patients with supraventricular tachycardia can be induced tachycardia on site, except for a very small number of patients, and some patients with preexcitation (dominant bypass) can be located without inducing tachycardia. Prior to electrophysiological examination, the patient is taken off antiarrhythmic drugs that may affect the results for several days (e.g., betalactam, cardioplegia, isoptin, amiodarone, etc.). Step 2: For the supraventricular tachycardia induced in the first step, radiofrequency ablation is performed. The doctor delivers a special catheter through the puncture site to the location of the “excess wire” and, with precise positioning, begins to dispense radiofrequency energy for a few tens of seconds or a few minutes to permanently eliminate the “excess wire”. Step 3: Repeat the first step of the “electrophysiological examination” again, at this time can no longer induce tachycardia, indicating that the “extra wire” has been removed. At this point, the physician withdraws all catheters and compresses and dresses the puncture site. No devices are left in the patient’s body. After the surgery, the patient usually recuperates for 1-2 days and most are discharged without incident, with the total length of stay generally ranging from 3-5 days. Is the procedure uncomfortable and painful? This is a question that many patients are concerned about. However, it is a little difficult to answer because it is very subjective and easily “influenced by the personality characteristics of the patient”. It should be said that “the surgery is very traumatic and the discomfort during the surgery is very minimal”. At the end of the surgery, we often say to the patient, “So-and-so, well, it’s done~~~!” Many patients are surprised to ask in return, “Ah~~~, this is done, so quickly …..” , which, from one side, reflects the fact that most surgeries, most patients, are smooth and easily tolerated. From the doctor’s point of view, of course, they will do their best to operate gently and accurately, and communicate with the patient in order to minimize the patient’s discomfort. However, there are some patients who are particularly timid and psychologically weak, so they tend to magnify this “discomfort”. Therefore, after treating many patients, our experience is that, in general, men are more likely to be nervous and scared than women, and therefore may feel “uncomfortable” more easily, especially in younger men (20-30 years old), who are most likely to be nervous, while in women, patients between the ages of 50-80 seem to be most relaxed. We have met big boys who are big and tall (200 pounds), who have cried out in pain before the doctor punctured the needle (of course, after repeated patient persuasion and chatting with the doctor, the surgery was eventually completed successfully), as well as skinny girls of the same age who completed the surgery calmly and comfortably. In fact, many patients are already done with the surgery before they are done being nervous. Of course, as doctors, we can understand this kind of nervousness of patients, after all, this is an unfamiliar experience that patients have never experienced before, and we doctors are willing to help patients to relieve this kind of fear and nervousness. For hospitals with many cases of patients with supraventricular tachycardia, there are often several patients with supraventricular tachycardia in the same ward, some of whom have successfully completed radiofrequency ablation and have not yet been discharged, while others have just been hospitalized and are waiting for surgery. “It is easier to adjust the mentality from the patient’s point of view in order to complete the operation successfully.
