Abstract
Transcatheter therapies for the treatment of structural heart diseases (SHD) have expanded dramatically over the last years, thanks to the developments and improvements of devices and imaging techniques, along with the increasing expertise of operators. Imaging, in particular echocardiography, is pivotal during patient selection, procedural monitoring, and follow-up. The imaging assessment of patients undergoing transcatheter interventions places demands on imagers that differ from those of the routine evaluation of patients with SHD, and there is a need for specific expertise for those working in the cath lab. In the context of the current rapid developments and growing use of SHD therapies, this document intends to update the previous consensus document and address new advancements in interventional imaging for access routes and treatment of patients with aortic stenosis and regurgitation, and mitral stenosis and regurgitation.

Wasserlauf J, Knight BP. Comparing the safety and effectiveness of dedicated radiofrequency transseptal wires to electrified metal guidewires. J Cardiovasc Electrophysiol 2022; 33:371-379. [PMID: 34978365 PMCID: PMC9303383 DOI: 10.1111/jce.15341] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Revised: 11/10/2021] [Accepted: 12/06/2021] [Indexed: 12/04/2022]
Abstract
Background Application of electrocautery to a metal guidewire is used by some operators to perform transseptal puncture (TSP). Commercially available dedicated radiofrequency (RF) guidewires may represent a better alternative. This study compares the safety and effectiveness of electrified guidewires to a dedicated RF wire. Methods TSP was performed on freshly excised porcine hearts using an electrified 0.014″ or 0.032″ guidewire under various power settings and was compared to TSP using a dedicated RF wire with 5 W power (0.035″ VersaCross RF System, Baylis Medical). The primary endpoint was the number of attempts required to achieve TSP. Secondary endpoints included the rate of TSP failure, TSP consistency, the effect of the distance between the tip of the guidewire and the tip of the dilator, and effect of RF power output level. Qualitative secondary endpoints included tissue puncture defect appearance, thermal damage to the TSP guidewire or dilator, and tissue temperature using thermal imaging. Results The RF wire required on average 1.10 ± 0.47 attempts to cross the septum. The 0.014″ electrified guidewire required an overall mean of 2.17 ± 2.36 attempts (2.0 times as many as the RF wire; p < .01), and the 0.032″ electrified guidewire required an overall mean of 3.90 ± 2.93 attempts (3.5 times as many as the RF wire; p < .01). Electrified guidewires had a higher rate of TSP failure, and caused larger defects and more tissue charring than the RF wire. Thermal analysis showed higher temperatures and a larger area of tissue heating with electrified guidewires than the RF wire. Conclusion Fewer RF applications were required to achieve TSP using a dedicated RF wire compared to an electrified guidewire. Smaller defects and lower tissue temperatures were also observed using the RF wire. Electrified guidewires required greater energy delivery and were associated with equipment damage and tissue charring, which may present a risk of thrombus, thermal injury, or scarring.

A novel and easy approach to difficult transseptal puncture during atrial fibrillation ablation. J Interv Card Electrophysiol 2020; 62:269-276. [PMID: 33034794 DOI: 10.1007/s10840-020-00891-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Accepted: 09/28/2020] [Indexed: 10/23/2022]
Abstract
AIMS Transseptal passage is sometimes difficult to obtain. This study evaluates the feasibility and safety of a novel and easy transseptal puncture (TSP) technique named 2D2G (using two dilators and two guidewires) in patients with difficult TSP. METHODS AND RESULTS Forty-four paroxysmal atrial fibrillation patients with difficult TSP were enrolled in this study. They were allocated to the 2D2G group or the conventional group in a 1:1 fashion. The primary endpoint in both groups was successful TSP without changing the puncture site or using auxiliary tools. The secondary endpoints were the safety, total transseptal puncture time, and ablation time. There were no differences in baseline demographic or clinical characteristics between the two groups. Successful LA access in the 2D2G group was 100% (vs. 64%, P < 0.05). The total TSP time (10 ± 3 min vs. 5 ± 1 min, P < 0.05) and ablation time (42 ± 19 min vs. 58 ± 22 min, P < 0.05) in the conventional group were significantly longer than those in the 2D2G group. No major complications occurred in either group, and all the patients underwent successful circumferential pulmonary vein isolation (CPVI). CONCLUSION In AF patients with difficult TSP, the 2D2G technique is safe, feasible, and time-saving.
