Case Reports in Clinical Medicine 2013年第8期2卷 460-462页

作者： Xiangmin Shi yutang wang Zhaoliang Shan Department of Cardiology The General Hospital of People’s Liberation Army Beijing China

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an autosomal dominant genetic form of cardiomyopathy (CM), which primarily affects the right ventricle (RV) and results in life threatening ventricular arrhythmias and sudden cardiac death (SCD). Diagnosis is difficult due to the broad spectrum of phenoltypic variations, especially in the early stage. Clinical suspicion should be raised in the setting of refractory ventricular tachycardia originating from the RV, and the final diagnosis could be made based on the combination of electrocardiography, echocardiography, cardiac magnetic resonance imaging (CMRI) and myocardial biopsy. Implantable cardioverter-defibrillator (ICD) implantation is an effective option for the treatment of ARVC.

Purpose: To investigate the alteration of left ventricular function in subjects with persistent atrial tachyarrhythmia induced cardiomyopathy (TIC) undergoing radiofrequency ablation, and to study the pathogenesis and effective treatment of TIC. Methods: A total of 25 cases with persistent atrial tachyarrhythmia and impaired left ventricular systolic function were studied (16 men and 9 women, aged 53.3 ± 15.2 years), and all subjects underwent electrophysiological study and radiofrequency ablation of atrial tachyarrhythmia under the guidance of CARTO system during 2006.9-2011.8. Indexes related to cardiac function, including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), New York Heart Association functional classification (NYHA class), 6 minutes walking test (6MWT), N-terminal pro-brain natriuretic peptide (BNP) and 24 hours average heart rate (AHR), were analyzed at the time point of 7 days, 3 and 6 months after the procedure as well as 1 day before ablation. Results: No refractory atrial arrhythmia recurred in all cases after ablation, compared with LVEDD (51.7 ± 4.5 mm), LVEF (39.0% ± 4.3%), number of patients with NYHA class IV and III (n = 17), 6MWT (212 ± 56 m), BNP (3622 ± 1860 ng/L) and AHR (112.5 ± 23.2 bpm) before ablation, the index of LVEDD (45.2 ± 3.3 mm;41.7 ± 2.5 mm;40.5 ± 3.1 m), BNP (2429 ± 1355 ng/L;1530 ± 866 ng/L;1300 ± 520 ng/L), total number of patients of NYHA class IV and III (n = 11;3;2) and AHR (73.3 ± 15.3 bpm;68.7 ± 13.5 bpm;66.3 ± 13.6 bpm) significantly decreased (P 0.05), no significant difference existed between 3 and 6 months in all indexes (P > 0.05).
