Disturbing effect of intra-tissue temperature sensors in pre-clinical experimental studies of radiofrequency cardiac ablation: A computer-based modeling study
Cuenca-Dacal, Luis; Berjano, Enrique; González-Suárez, Ana; Pérez, Juan J. (MDPI, 2023-04-11)Background: Preclinical studies on radiofrequency (RF) cardiac ablation (RFCA) use very small temperature sensors in specific positions in the tissue subjected to RF heating. Despite the sensors¿ small size, the proximity ... -
How far the zone of heat-induced transient block extends beyond the lesion during RF catheter cardiac ablation
Pérez, Juan J.; Berjano, Enrique; González-Suárez, Ana (Taylor and Francis Group, 2023-01-02)Purpose While radiofrequency catheter ablation (RFCA) creates a lesion consisting of the tissue points subjected to lethal heating, the sublethal heating (SH) undergone by the surrounding tissue can cause transient ... -
Impact of ultra-short pauses between stacked lesions with and without active esophageal cooling
Mercado Montoya, Marcela; Gomez Bustamante, Tatiana; Berjano, Enrique; Mickelsen, Steven R.; Hernandez Arango, Pablo; González Suárez, Ana; Schieber, Jay; Kulstad, Erik; Daniels, James D. (Oxford University Press, 2023-05-24)Background Placing lesions at the same point (stacking lesions) in the left atrium during radiofrequency (RF) ablation can increase the risk of collateral injury. The use of active esophageal cooling has been shown to ... -
Proactive esophageal cooling during laser cardiac ablation: A computer modeling study
Gomez Bustamante, Tatiana; Mercado Montoya, Marcela; Berjano, Enrique; González Suárez, Ana; Kulstad, Erik (Wiley, 2024-03-04)Background and Objectives Laser ablation is increasingly used to treat atrial fibrillation (AF). However, atrioesophageal injury remains a potentially serious complication. While proactive esophageal cooling (PEC) reduces ... -
Relationship between mechanical deformation and contact force applied by a catheter tip on cardiac muscle: Experimentation and computer modeling
Ijima, Yukako; Masnok, Kriengsak; Perez, Juan J.; González-Suárez, Ana; Berjano, Enrique; Watanabe, Nobuo (IEEE, 2023-08-25)The cardiac muscle is elastic and deformable. Pushing a catheter in contact with the cardiac muscle surface to conduct focal energy-based ablative therapies, such as RF ablation, requires an adequate electrode-tissue contact ...
