Cardiac herniation and volvulus with acquired dextrocardia: echocardiographic diagnosis

We report an extremely rare cause of elevated jugular venous pulse where two esoteric causes for the same-cardiac volvulus and cardiac herniation have occurred together. Echocardiographic evidence for making the diagnosis of cardiac volvulus--subcostal long axis, subcostal short axis, and suprasternal views--have been presented. Awareness of this complication is necessary as immediate intervention is mandatory for a positive outcome.     

先天性右位心伴内脏转位植入心脏再同步治疗除颤器一例

患者男52岁,因＂反复心力衰竭发作＂在第四军医大学西京医院治疗,超声心动图示：右位心,左心室射血分数（LVEF）0.29;心电图示：右位心,电轴左偏,完全性左束支阻滞,QRS时限144 ms;动态心电图示：频发的室性早搏（室早）,并伴短阵室性心动过速（室速）,最长持续时间3 s.患者符合心室再同步治疗的Ⅰ类适应证,准备植入心脏再同步治疗除颤器（CRT-D,7298,美国美敦力公司）.成功穿刺右锁骨下静脉,导引钢丝植入时很难进入下腔静脉,通过钢丝走行判定其进入传统意义上的右心房（图1A）,但指引导管在进入冠状静脉窦口时导致夹层,改用冠状动脉延迟造影观察心脏静脉的走行,发现夹层应在心中静脉开口（图1B）,重新进入指引导管到心大静脉逆行造影（图1C）,选择心侧静脉为靶血管植入左心室导线（4195,美国美敦力公司）,随后顺利植入右心室及右心房导线（图1D）.     

Coronary arteriography in patients with dextrocardia

Coronary arteriography is described in a patient with dextrocardia and situs inversus totalis. Six cases of coronary arteriography in dextrocardia were reviewed from the literature, and 3 other cases were reported from the authors' institutions. In 9 of the 10 patients, coronary arteriography was performed without difficulty using standard Judkins or Sones catheters. Angiographers encountering patients with dextrocardia may use standard coronary arteriographic techniques with a few subtle modifications.     

Primary angioplasty in a patient with dextrocardia

Dextrocardia is a rare anomaly affecting 0.01% of newborns. We report on a case of a 60-year-old female with mirror-image dextrocardia who presented with an acute myocardial infarction and underwent primary angioplasty of the left circumflex artery. A review of the literature and technical challenges of the case will be addressed.     

Coronary angioplasty in a patient with dextrocardia

This report, concerning the procedures applied to a patient with dextrocardia, describes how such a patient was able to undergo a normal diagnostic catheterization. These data should be added to the limited data on interventional procedures in patients who have this anomaly.     

Myocardial revascularization in dextrocardia with situs inversus]

BACKGROUND: The incidence of coronary artery disease in patients with dextrocardia associated with situs inversus is similar to that of the general population: Nevertheless, there are few papers regarding surgical myocardial revascularization in these patients. METHODS: We report two patients with dextrocardia and situs inversus who underwent myocardial revascularization by means of coronary artery bypass grafting, with the right internal mammary artery to the left anterior descending coronary artery in one case and with the left internal mammary artery as a free graft to the left anterior descending coronary artery associated with the repair of an aneurysm of the right coronary sinus of Valsalva in the second patient. RESULTS: There were no surgical complications; the patients were discharged on the 4th and 7th postoperative days, respectively. They are alive and well after 24 and 60 months of follow-up respectively. CONCLUSIONS: This report suggests that durable myocardial revascularization in dextrocardia with situs inversus can be successfully achieved with right or left mammary artery bypass grafting to the left anterior descending coronary artery. The advantage of using an in situ mammary artery is discussed.
