Zero-fluoroscopy transseptal puncture guided by right atrial high dense precision mapping: First in human experience

Zero-fluoroscopy procedures have recently become feasible in catheter ablations, and transseptal puncture (TSP) is the key step of this procedure. With use of the TSP method, zero-fluoroscopy method can be performed in three ways, with transesophageal echocardiography, intracardiac echocardiography or total 3-dimensional technique. However, each method has its own shortcomings. Here, we documented, for the first time to the best of our knowledge, that carried out zero-fluoroscopy TSP guided by right atrial high dense precision mapping using a PentaRay multipolar mapping catheter combined with ConfiDense intelligent high-precision mapping technology, which avoid the shortness of previous method.
