Assessment of Admission Hemoglobin Levels and Gender Differences in Transvenous Radiofrequency Ablation Therapy for the Treatment of the Slow Pathway of Atrioventricular Nodal Reentrant Tachycardia

Abstract

Introduction: Atrioventricular nodal reentrant tachycardia is the most common regular supraventricular arrhythmia in humans. This study investigated the admission hemoglobin levels and gender differences in transvenous radiofrequency ablation therapy for the treatment of the slow pathway of atrioventricular nodal reentrant tachycardia. Patients and Methods: Nineteen consecutive patients with symptomatic drug-resistant typical slow-fast atrioventricular nodal reentrant tachycardia underwent an invasive electrophysiology study and performed radiofrequency ablation of slow conduction pathway within atrioventricular node. Blood samples were taken between 08.30 and 09.30 a.m. from the antecubital vein for complete blood count. Results: Nineteen consecutive patients with slow-fast atrioventricular nodal reentrant tachycardia (12 female, 7 male) were ablated. Mean admission hemoglobin and hematocrit (%) levels were significantly increased in male patients as compared with female patients (15.38 ± 1.21 mg/ dL, 12.72 ± 1.36 mg/dL, p < 0.001; 45.41 ± 3.26, 37.90 ± 2.88, p < 0.001 respectively). There was not gender differences in the radiation exposure time, fluoroscopy time, complication rate (0%) and acute success rate (100%).Conclusion: There was not gender differences in the radiation exposure time, fluoroscopy time, complication rate and acute success rate at the transvenous radiofrequency ablation therapy for the treatment of atrioventricular nodal reentrant tachycardia. Mean admission hemoglobin and hematocrit levels were significantly decreased in female patients as compared with male patients.

Atriyoventriküler Nodal Reentran Taşikardide Yavaş Yolun Transvenöz Radyofrekans ile Ablasyonunda Başvuru Hemoglobin Seviyeleri ve Cinsiyet Farklılığının Değerlendirilmesi

Abstract

Giriş: Atriyoventriküler nodal reentran taşikardi insanda en sık gözlenen düzenli supraventriküler aritmidir. Bu çalışmada, atriyoventriküler nodal reentran taşikardide yavaş yolun transvenöz radyofrekans ile ablasyonunda başvuru hemoglobin seviyeleri ve cinsiyet farklılığı araştırılmıştır. Hastalar ve Yöntem: Semptomatik, ilaca dirençli tipik (yavaş-hızlı) atriyoventriküler nodal reentran taşikardisi olan 19 ardışık hasta, invaziv elektrofizyoloji çalışması ve atriyoventriküler yavaş iletim yolunun radyofrekans ablasyonu için çalışmaya alındı. Sabah saat 08.30- 09.30 aralarında tam kan sayımı için antekübital venden kan örneği alındı. Bulgular: Yavaş-hızlı atriyoventriküler nodal reentran taşikardisi olan (12 kadın, 7 erkek) 19 ardışık hasta ablate edildi. Ortalama başvuru hemoglobin ve hematokrit (%) değerleri erkeklerde kadınlara göre daha yüksekti (sırası ile, 15.38 ± 1.21 mg/dL, 12.72 ± 1.36 mg/dL, p < 0.001; 45.41 ± 3.26, 37.90 ± 2.88, p < 0.001). Radyasyon maruziyet zamanı, floroskopi zamanı, komplikasyon oranı (%0) ve akut başarı oranı (%100) açısından cinsiyet farklılığı yoktu. Sonuç: Atriyoventriküler nodal reentran taşikardinin transvenöz radyofrekans ablasyonu ile tedavisinde radyasyon maruziyet zamanı, floroskopi zamanı, komplikasyon oranı ve akut başarı oranı açısından cinsiyet farklılığı saptanmamıştır. Başvuru ortalama hemoglobin ve hematokrit değerleri kadınlarda erkeklere göre daha düşüktür
