Myocardial revascularization in a patient with situs inversus totalis

We report the case of a patient with dextrocardia and situs inversus totalis associated with obstructive coronariopathy in the anterior and posterior descending arteries, right coronary artery, first diagonal branch and left marginal branch. The patient underwent coronary artery bypass grafting surgery. This surgery has been rarely reported in literature and we found only one similar case in the national medical literature. The myocardial revascularization was carried out with the right mammary artery for the anterior descending artery. The saphenous vein anastomosed the aorta to the right coronary artery, left marginal branch, fist diagonal branch and posterior descending artery. The surgery was performed with extracorporeal circulation.     

Discrete type subaortic stenosis in dextrocardia with situs inversus totalis

This paper presents the case report of a patient with discrete type subaortic stenosis in dextrocardia and its associated clinical manifestations.     

Biventricular implantable cardiac defibrillator in dextrocardia with situs viscerum inversus.

A case of dextrocardia in situs viscerum inversus, prior myocardial infarction, dilated cardiomyopathy with severe left ventricular systolic dysfunction, ventricular tachyarrhythmias and recurrent episodes of heart failure is described. Coronary artery bypass grafting for multivessel coronary artery disease had been previously performed; coronary and graft anatomy evaluation excluded the possibility of any further revascularization procedure. Electrocardiography showed left bundle branch block and echocardiography revealed significant interventricular mechanical dyssynchrony. After a complete vascular and cardiac anatomy evaluation, the patient was submitted to biventricular cardiac defibrillator implantation via a right approach and using conventional fluoroscopic equipment.     

Acute myocardial infarction in a patient with dextrocardia and situs inversus

We report a case of 54-year-old man who presented to hospital with severe prolonged retrosternal chest pain of anginal nature. Electrocardiogram taken by his general practitioner showed minimal ST elevation in chest leads V1 and V2; there was also marked right axis deviation of P wave (negative in lead I and aVL) and of QRS complexes, together with low voltage in precordial leads V4 through V6 suggestive of dextrocardia. Repeat electrocardiogram with chest and limb leads reversed showed widespread, significant ST elevation in lead I, aVL, and V1 through V5 in keeping with extensive acute anterior myocardial infarction (MI). High cardiac enzymes and troponin level provided further confirmation. The extent of MI in such patients may be underestimated unless dextrocardia is timely recognized and leads reversed. We recommend that for patients with dextrocardia and situs inversus presenting with MI, both chest and limb leads be reversed to reveal the true extent of the infracted area.     

Mitral valve replacement in a patient with situs inversus and dextrocardia

Dextrocardia is a rarely seen cardiac malposition, often associated with multiple and complex congenital cardiac anomalies. Valve surgery for acquired valvular lesions in dextrocardia with situs inversus is rare. A 65-year-old man was admitted to our department with palpitation and dyspnea. Chest X-ray showed dextrocardia, and echocardiography revealed severe mitral regurgitation due to rheumatic valve degeneration. Prosthetic mitral valve replacement using a transseptal approach via a median sternotomy was successfully performed in the patient.     

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）.     

Aortic atresia with situs inversus]

We report a case of mitro-aortic atresia with situs inversus. The patient was studied with two-dimensional echocardiography and the diagnosis was confirmed in the necropsy. Our newborn infant is the second case reported with this abnormality and the first in our country.     

Angina pectoris associated with dextrocardia and situs inversus (case report)

A case of angina pectoris with pain radiating to the right arm is reported in an individual with dextrocardia with situs inversus.
