Implantation of a dual-chamber pacemaker in a patient with dextrocardia and sick sinus syndrome: a case report

Dextrocardia is a congenital abnormal position of the heart in which the main part of the heart is in the right chest, and the long axis of the heart points to the lower right. Cases of a combination of dextrocardia and sick sinus syndrome are rare. A 65-year-old female patient was admitted to hospital with palpitations and dizziness for 1 week. Mirror-image dextrocardia and sick sinus syndrome were diagnosed by an electrocardiogram, echocardiography, Holter monitoring, and X-rays. Finally, we successfully implanted a dual-chamber pacemaker into the patient. The patient had an uneventful recovery and was discharged when her symptoms had greatly improved 1 week later. When dextrocardia is present, using active fixation leads in the atrial and ventricular leads is easier for finding the pacing position with optimal sensing and pacing thresholds, and they reduce the incidence of falling off.     

单发右位心的心血管造影与外科术后诊断对比研究

目的比较单发右位心的心血管造影与外科术后诊断,评价心血管造影诊断结果的准确性,探讨最佳的造影方法及投照体位.方法27例先天性单发右位心病例接受外科姑息性或根治手术治疗,回顾性分析其心血管造影资料（常规左、右室造影,其中8例行选择性心房造影,18例加行双斜位）,根据先天性心脏病节段分析法原则,将其与外科术后诊断进行对比研究.结果心血管造影诊断与外科术后诊断结果对比显示22例诊断基本一致,5例不一致,包括1例解剖校正型大动脉错位误诊为功能校正型大动脉错位,1例完全性大动脉错位误诊为功能校正型大动脉错位,1例单心室误诊为右室双出口（合并心房不定位误诊为心房正位）,2例解剖左室双出口误诊为功能校正型大动脉错位.结论单发右位心并复杂的心血管病畸形,因解剖复杂,在常规行双侧心室造影和正侧位造影基础上加行选择心房造影和双斜位造影,有利于达到准确诊断的目的.     

A Rare Congenital Finding in an Elderly Lady—Scimitar Syndrome with Dextrocardia in a 79 Year Old

We present a case of a 79-year-old African-American woman with scimitar syndrome and associated dextrocardia. This case represents, to our knowledge, the oldest living patient described in the literature with scimitar syndrome.     

Left-Sided Gallbladder Discovered During Laparoscopic Cholecystectomy in a Patient with Dextrocardia

Left-sided gallbladder, a rare congenital anomaly, is often associated with transposition of single or multiple viscera of thorax and/or abdomen. Clinical features and routine presurgical ultrasonography could miss the anomalous position thereby producing unnecessary anxiety during surgery. Here we are reporting a patient with left-sided gallbladder, known to have dextrocardia with multiple intracardiac anomalies, and detected incidentally in a series of 1258 consecutive laparoscopic cholecystectomies. Laparoscopic cholecystectomy was performed successfully in this patient with port site modification and careful dissection. Some degree of abdominal visceral situs inversus is to be anticipated in patients with dextrocardia     

The Very Low Birthweight Neonate With an Interrupted Aortic Arch and Dextrocardia

Type 1A interruption of the aortic arch complex accompanied by mirror-image dextrocardia with situs inversus was diagnosed by counter-current aortography through the radial artery. This technique is useful for aortography of the very low birthweight neonate.     

成人右旋心及合并畸形彩色多普勒超声心动图特征

目的探寻成人右旋心及合并畸形的彩色多普勒超声心动图(CDE)特征。资料与方法应用CDE检查30例成人右旋心及合并畸形,寻找成人右旋心及合并畸形CDE特征,所有病例均心血管造影对照,26例手术证实。结果根据CDE特征,对所有病例全部做出正确诊断。成人右旋心及合并畸形CDE特征明显:①成人右旋心合并4种先天性心脏病,其中SLL型矫正性大动脉转位(80.0%)多见,AⅢ型心室双入口(10.0%)、SLL型右心室双出口(6.7%)和孤立性房间隔缺损(3.3%)少见。②成人右旋心无论合并那种先天性心脏病,CDE表现均为心房正位。③成人右旋心合并矫正性大动脉转位、心室双入口和右心室双出口的大动脉均为左转位。④成人右旋心合并复杂先天性心脏病多有肺动脉狭窄(93.3%)。肺动脉狭窄时,彩色多普勒血流显像显示过肺动脉五彩镶嵌射流束血流信号。⑤合并房间隔缺损和室间隔缺损时,彩色多普勒血流显像显示过房间隔或室间隔左向右或双向五彩镶嵌分流束血流信号。结论成人右旋心及合并畸形的CDE特征明显,应用CDE对成人右旋心及合并畸形可做出正确诊断,但检查者必须熟练掌握本病解剖。在探查手法上与正常位心脏明显不同,检查前阅读X线正位胸片对CDE正确诊断有帮助,并可提高检查效率。
