International Journal of Hyperthermia, 2017Co-Authors: Noureldin A Noureldin, Sybille Exner, Mohammed Alsubhi, N Naguib, Benjamin Kaltenbach, Andrei Roman, Thomas J VoglAbstract:AbstractPurpose: To retrospectively compare the local tumour response and survival rates in patients with non-colorectal cancer lung metastases post-Ablation Therapy using laser-induced thermoTherapy (LITT), radiofrequency Ablation (RFA) and microwave Ablation (MWA).Material and methods: Retrospective analysis of 175 computed tomography (CT)-guided Ablation sessions performed on 109 patients (43 males and 66 females, mean age: 56.6 years). Seventeen patients with 22 lesions underwent LITT treatment (tumour size: 1.2–4.8 cm), 29 patients with 49 lesions underwent RFA (tumour size: 0.8–4.5 cm) and 63 patients with 104 lesions underwent MWA treatment (tumour size: 0.6–5 cm). CT scans were performed 24-h post-Therapy and on follow-up at 3, 6, 12, 18 and 24 months.Results: The overall-survival rates at 1-, 2-, 3- and 4-year were 93.8, 56.3, 50.0 and 31.3% for patients treated with LITT; 81.5, 50.0, 45.5 and 24.2% for patients treated with RFA and 97.6, 79.9, 62.3 and 45.4% for patients treated with MWA, respec...

Radiofrequency Ablation of a left anterior accessory pathway in a patient with Wolff-Parkinson-White and major venous drainage anomaly.
International Journal of Cardiology, 2007Co-Authors: Rosaly Bucce, John Inglessis, Abdel J FuenmayorAbstract:Anomalies of the venous system may impose serious limitations to the treatment of arrhythmias by means of Ablation Therapy. We describe a patient who had the Wolff-Parkinson-White syndrome with frequent episodes of antidromic supraventricular tachycardia in whom an Ablation was performed. The patient was found to have no inferior vena cava, a hemiazygos vein draining in a persistent left superior vena cava, and a left anterior manifest accessory pathway.

atypical atrioventricular nodal reentry tachycardia with atrioventricular block mimicking atrial tachycardia electrophysiologic properties and radiofrequency Ablation Therapy
Journal of Cardiovascular Electrophysiology, 1997Co-Authors: Yasuhiro Taniguchi, Chunchieh Wang, W U DelonAbstract:AVNRT Mimicking Atrial Tachycardia, Introduction: Fast-intermediate form AV nodal reentry tachycardia (AVNRT) sometimes may mimic atrial tachycardia or atrial flutter and render the diagnosis difficult when the tachycardia rate is fast and AV block occurs during tachycardia. Methods and Results: A 45-year-old woman with paroxysmal supraventricular tachycardia was referred to this institution. Initially, the tachycardia was thought to be an atrial tachycardia because of: (1) a short cycle length of the tachycardia with 2:1 and Wenckebach AV block; (2) a difference in the atrial activation sequence during tachycardia and during ventricular pacing; and (3) failure of burst ventricular pacing to affect the atrial rate and the atrial activation sequence during tachycardia. An accurate diagnosis of fast-intermediate form AVNRT was subsequently made based on the finding that the tachycardia was induced following delivery of a third ventricular extrastimulus, which showed a sequence of V-A-H and a change on atrial activation sequence of the induced beat. Successful radiofrequency Ablation was achieved only after accurate diagnosis of the tachycardia was made. Conclusion: Fast-intermediate form AVNRT sometimes may masquerade as atrial tachycardia. Accurate diagnosis is mandatory for successful Ablation Therapy.

Radiofrequency Ablation Therapy in atypical or multiple atrioventricular node reentry tachycardias
American Heart Journal, 1994Co-Authors: Chunchieh Wang, I-ching Chen, Delon WuAbstract:Electrophysiologic study and radiofrequency Ablation Therapy were performed in 23 patients with atypical (8 patients) or multiple (15) atrioventricular node reentry tachycardias. Dual pathways with anterograde fast and slow pathway conductions were demonstrated in 16 patients. Studies on retrograde conduction revealed the presence of three different pathways, including fast (15 patients), intermediate (17), and slow (16). The radiofrequency current was applied to the inferior aspect, one-third anterior two-thirds posterior between the His bundle and the ostium of the coronary sinus, of Koch's triangle along the tricuspid annulus in all patients. Application of the current resulted in selective Ablation or modification of both retrograde intermediate and slow pathway conductions in 20 patients. In two patients retrograde fast pathway conduction was also modified. Complete atrioventricular block occurred in the remaining patient. Sixteen patients had no induction of tachycardia or echo, 4 had induction of a single echo, and 2 had induction of the slow-fast form tachycardia; one of those 2 patients underwent a second trial and was successful. A median application of 2 was delivered at a power of 25 ± 5 W and a duration of 18 ± 4 sec. The total fluoroscopic time was 25 ± 21 minutes. The anterograde fast pathway conduction was unaffected; the shortest atrial paced cycle length that sustained 1:1 fast pathway conduction was 329 ± 65 msec and 330 ± 68 msec before and after Ablation, respectively. A follow-up electrophysiologic study was performed in 16 patients 60 ± 15 days after Ablation. Eleven had no induction of tachycardia or echo, and five had induction of

Late clinical and electrophysiologic outcome of radiofrequency Ablation Therapy by the inferior approach in atrioventricular node reentry tachycardia
American Heart Journal, 1994Co-Authors: Chunchieh Wang, I-chang Hsieh, Delon WuAbstract:Abstract A late electrophysiologic study was conducted in 182 of 289 patients with slow-fast atrioventricular node reentry tachycardia 81 ± 36 days after radiofrequency Ablation Therapy by the inferior approach. Of these 182 patients, electrophysiologic study immediately after Ablation revealed a selective modification of the slow pathway in 159, a modification of both the slow and fast pathways in 15, a modification of the fast pathway alone in 3, and failure of Ablation in 5. One hundred two patients had no induction of echoes; 75 had induction of fewer than four echoes; and 5 had induction of sustained tachycardia with or without isoproterenol infusion. The late electrophysiologic study in these 182 patients revealed a persistent effect without changes in conduction properties in 161 (88%) patients. A change in conduction properties was noted in 21 patients, including 5 with resumption of slow- or fast-pathway conduction with induction of sustained tachycardia, 8 with improved fast- or slow-pathway conduction, and 8 with an additional depression of fast- or slow-pathway conduction. Of the 102 patients with no induction of echoes and the 75 patients with induction of fewer than four echoes during the immediate postAblation electrophysiologic study, 5 (3 and 2, respectively) patients had induction of tachycardia. Of the 5 patients with induction of sustained tachycardia in the immediate postAblation electrophysiologic study, 3 continued to have induction of sustained tachycardia; 1 had induction of echoes only; and 1 had no induction of echoes. The predictability of late success by using a combination of induction of no and fewer than four echoes in the immediate postAblation electrophysiologic study had a sensitivity of 99%, a specificity of 38%, a positive predictive value of 97%, a negative predictive value of 60%, and a total predictive accuracy of 96%. Thus the effects of radiofrequency Ablation persist in the majority of patients during follow-up, and elimination of all echoes is unnecessary for achieving a late success.

the use of endovenous laser treatment in toddlers
Journal of Vascular and Interventional Radiology, 2013Co-Authors: Kendall King, Mary Landriganossar, Robert K Clemens, Gulraiz Chaudry, Ahmad I AlomariAbstract:The use of endovenous laser Ablation Therapy in children is limited. Klippel-Trenaunay syndrome (KTS) is associated with persistent ectatic anomalous veins within the affected extremity, with increased risk of thromboembolism. The present report describes four toddlers (<20 kg) with KTS of the lower extremity who underwent a total of five endovenous laser procedures for treatment of ectatic anomalous marginal venous system, without complications.
