During catheter ablation, delivery of radiofrequency(RF) energy to a target site is sometimes interrupted due to catheter instability and clinical factors; the impact of interruption of RF delivery on lesion characteristics has not been characterized.

Design and optimization of statistical models for use in methods for estimating radiofrequency ablation (RFA) lesion depths in soft real-time performance.
Contact force (CF) between radiofrequency (RF) ablation catheter and myocardium and ablation index (AI) correlates with RF lesion depth and width in normal-voltage (>1.5 mV) myocardium (NVM). We inves...
Background Radiofrequency ablation (RFA) is a common approach to treat cardiac arrhythmias. During this intervention, numerous strategies are applied to indirectly estimate lesion formation. However, ...
Cutting balloons and scoring balloons are commonly used for the preparation of calcified lesion. However, problems with crossability occasionally limit the use of cutting balloons. We prospectively se...
To date, there is limited data on evaluation of the cordotomy lesion and predicting clinical outcome.
This study is to evaluate the safety and efficacy of radiofrequency energy procedure for Gastro-esophageal reflux disease (GERD) based on changes of symptoms, medication esophagitis grade,...
In 2017, all IMPACTT investigators experimented in coordinated manner on multifacet intervention program, proposed by the present research protocol, with 2 teams from healthcare units from...
The purpose of this study is to perform a prospective, randomised study investigating the safety and efficacy of cryoballoon catheter ablation compared with radiofrequency ablation in the ...
In this randomized study, two energy sources for the ablation of AV nodal reentry tachycardia are compared: The standard technique of radiofrequency energy delivery is compared with the n...
A study in the postpartum period reveals that among women who delivered vaginally and having perineal lesions, between 95 and 100% of them suffer from perineal pain (episiotomy, tears from...
The application, via IMPLANTED ELECTRODES, of short bursts of electrical energy in the radiofrequency range, interspersed with pauses in delivery of the current long enough to dissipate the generated heat and avoid heat-induced tissue necrosis.
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.
Those characteristics that distinguish one SEX from the other. The primary sex characteristics are the OVARIES and TESTES and their related hormones. Secondary sex characteristics are those which are masculine or feminine but not directly related to reproduction.
A lesion with cytological characteristics associated with invasive carcinoma but the tumor cells are confined to the epithelium of origin, without invasion of the basement membrane.
