Assessment of the Relationship Between Waist Circumference as an Anthropometrical Indicator of Central Obesity and Fluoroscopic Exposure Time in Different Gender Patients Who Underwent Radiofrequency Catheter Ablation Due to Antiarrhythmic Drug-Refractory Tachycardia: a Multicenter Study

Abstract

Introduction: Radiofrequency catheter ablation therapy has been used to treat arrhythmia such as supraventricular and/or ventricular tachycardia. Increased waist circumference is important in assessing central obesity and may be an important factor for radiation injury. Therefore, this article describes the association between waist circumference and fluoroscopic exposure time during cardiac radiofrequency catheter ablation procedures for symptomatic drug-resistant tachycardia.

Patients and Methods: From August 2011 to March 2015, 214 (136 women, 78 men) consecutive patients with symptomatic drug-resistant atrioventricular nodal re-entrant tachycardia (174 patients), atrioventricular re-entrant tachycardia (12 patients), Wolf-Parkinson-White syndrome (5 patients), atrial tachycardia (8 patients), atrial flutter (7 patients), right ventricular outflow tract tachycardia (5 patients), and atrial fibrillation (3 patients) underwent an invasive electrophysiological study and radiofrequency catheter ablation. The fluoroscopic exposure time, radiofrequency catheter ablation time, and waist circumference were measured during the electrophysiological study.

Results: Although age was significantly higher in women than in men, body weight, body height, waist circumference, and radiofrequency catheter ablation time were significantly higher in men than in women. There was a correlation between waist circumference and fluoroscopic exposure time (p= 0.04, r= 0.13).

Conclusion: The study showed that there was a positive correlation between waist circumference and fluoroscopic exposure time in patients with antiarrhythmic drug-refractory tachycardia who underwent radiofrequency catheter ablation. This finding could help prevent radiation injury, especially increased waist circumference during radiofrequency catheter ablation.

Anti-Aritmik İlaçlara Dirençli Taşikardi Nedeni ile Radyofrekans Kateter Ablasyon Uygulanan Hastalarda Santral Obezitenin Antropometrik Bir Ölçütü Olarak Bel Çevresi ile Floroskopi Maruziyet Süresi Arasındaki İlişkinin Değerlendirilmesi: Çok Merkezli Çalışma

Abstract

Giriş: Radyofrekans kateter ablasyon tedavisi supraventriküler ve/veya ventriküler aritmilerin tedavisinde kullanılmaktadır. Artmış bel çevresi santral obeziteyi değerlendirmede önemli bir yöntemdir, aynı zamanda radyasyon hasarı için de önemli bir faktör olabilir. Bu nedenle bu makale semptomatik ilaca dirençli taşikardi nedeni ile yapılan kardiyak radyofrekans kateter ablasyonu sırasındaki floroskopi maruziyet süresi ile bel çevresi arasındaki ilişkiyi irdelemektedir.

Hastalar ve Yöntem: Ağustos 2011 ila Mart 2015 tarihleri arasında semptomatik ilaca dirençli; atriyoventriküler nodal re-entran taşikardi (174 hasta), atriyoventriküler re-entran taşikardi (12 hasta), Wolf Parkinson White sendromu (5 hasta), atriyal taşikardi (8 hasta), atriyal flutter (7 hasta), sağ ventriküler çıkış yolu taşikardisi (5 hasta), atriyal fibrilasyon (3 hasta) nedenleri ile invaziv elektrofizyolojik çalışma ve radyofrekans ablasyon uygulanan 214 (136 kadın, 78 erkek) ardışık hasta çalışmaya dahil edildi. Floroskopi maruziyet süresi, radyofrekans ablasyon zamanı ve bel çevresi işlem sırasında ölçüldü.

Bulgular: Kadınların yaşı anlamlı olarak erkeklerden yüksek olsa da vücut ağrılığı, boy, bel çevresi ve radyofrekans ablasyon süresi erkeklerde kadınlara göre daha anlamlı olarak yüksekti. Bel çevresi ile floroskopi maruziyet süresi arasında bir korelasyon mevcuttu (p= 0.04, r= 0.13).

Sonuç: Çalışmamız göstermiştirki, antiaritmik ilaç dirençli taşikardi nedenli radyofrekans kateter ablasyon uygulanan hastalarda floroskopi maruziyet süresi ile bel çevresi arasında pozitif bir korelasyon mevcuttur. Bu bulgu özellikle artmış bel çevresi olan hastalarda radyofrekans kateter ablasyon sırasında radyasyon hasarını önlemek için faydalı olabilir.
