1/26. Coronary stenting in patients with situs viscerum inversus.Atherosclerotic coronary disease may develop even in patients with complex cardiovascular anomalies who reach adult life. Coronary revascularization (surgical or interventional) may present potential difficulties related to the unusual anatomy. We describe two cases of situs viscerum inversus who underwent cardiac catheterization and angiography as adults because of ingravescent angina. The study identified the cardiac relations and connections, and diagnosed severe coronary disease that was successfully treated with coronary angioplasty and stent implantation. The implications of performing such procedures in patients with similar cardiac anomalies are discussed.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/26. situs inversus totalis and single coronary ostium: A coincidence or a pattern?situs inversus totalis and single coronary ostium are rare congenital anomalies, and no ontogenic connection has been described between them. Only three cases of association of single coronary ostium and situs inversus have been reported in the literature, all found on angiography. Here we present the first case of this association discovered at autopsy. Based on the apparently higher than expected frequency of this finding, an underlying pathologic connection between these conditions is proposed.- - - - - - - - - - ranking = 2keywords = coronary (Clic here for more details about this article) |
3/26. Multiple coronary artery bypass grafting in dextrocardia: case report.This is a case report of an unusual case of a patient with dextrocardia and "situs inversus totalis" who presented with unstable angina. coronary angiography revealed severe main stem and severe triple vessel coronary artery disease. The patient later underwent successful emergency coronary artery bypass graft surgery. To the authors' knowledge this is the first reported case in malaysia and also, the first ever report in the literature of multiple vessel coronary artery grafting, including the use of the right internal mammary artery.- - - - - - - - - - ranking = 2.3333333333333keywords = coronary (Clic here for more details about this article) |
4/26. Coronary stent deployment in situs inversus.situs inversus with dextrocardia occurs in approximately one in 10 000 patients. Successful stent deployment for the treatment of unstable angina and situs inversus is presented. Three technical challenges associated with the procedure are highlighted. Firstly, the successful choice of diagnostic and interventional catheters is based on an understanding of the orientation of the aortic arch. With a right sided aorta Judkins catheters should be successful. Secondly, image reversal is not necessarily required for image interpretation. Thirdly, successful coronary engagement with catheters requires rotation in a direction opposite to that normally used.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
5/26. Case report: off-pump total myocardial revascularization for dextrocardia and situs inversus.A 42-year-old man with dextrocardia and situs inversus underwent successful off-pump total myocardial revascularization using the technique popularized by Tector [Tector 1994, Tector 1996]. The free left internal mammary artery (LIMA) was anastomosed to the in-situ right internal mammary artery (RIMA) at the level of the right-sided left atrial appendage, then anastomosed sequentially to the first diagonal branch (D1) of the left anterior descending artery (LAD), and to the LAD. The in-situ RIMA was sequentially anastomosed to the first and the second obtuse marginal branches (OM1 and OM2) of the circumflex coronary artery. A saphenous vein was then anastomosed to a diffusely diseased posterior descending branch (PDA) of the right coronary artery (RCA). The patient was asymptomatic and in excellent condition three months after surgery. In economically depressed regions of the world, such as the Gaza Strip, off-pump complete revascularization is an excellent alternative to cardiopulmonary bypass.- - - - - - - - - - ranking = 0.66666666666667keywords = coronary (Clic here for more details about this article) |
6/26. situs inversus totalis associated with subaortic and subpulmonic stenosis.The unusual occurrence of total situs inversus and idiopathic hypertrophic subaortic stenosis with the demonstration of right and left heart dynamic obstruction in one patient is presented. The fact that the patient was known to have a rare abnormality (total situs inversus) and the presenting symptom being angina pectoris, may have obscured the diagnosis of IHSS and emphasized the value of comprehensive evaluation of patients. The documentation of right ventricular dynamic obstruction, in addition to obstruction of the left side of the heart, was facilitated by the use of simultaneous pressure recordings in the pulmonary artery and in the body of the right ventricle. The angina-like pain was secondary to left ventricular outflow obstruction, rather than to coronary disease.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
7/26. Beating heart surgery in a patient with dextrocardia and complete situs inversus.We present a 65-year-old female patient with dextrocardia and situs inversus who underwent successful coronary artery bypass without cardiopulmonary bypass. Vessels revascularized included right internal mammary artery to the left anterior descending artery and a saphenous vein graft to the first obtuse marginal branch. The procedure was performed on a beating heart through a median sternotomy with the use of a compression epicardial stabilizer. The patient was discharged to her home after an uneventful recovery. Only 12 similar cases of myocardial revascularization in patients with dextrocardia have been reported so far, and this is one of the first procedures, in patients with dextrocardia, performed off pump.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
8/26. situs inversus, subaortic and subpulmonic stenosis, ventricular septal defect, and single coronary artery.The unusual occurrence of situs inversus totalis, ventricular septal defect, hypertrophic subaortic and subpulmonic stenosis, and single coronary artery in a 38-year-old man is presented. The clinical course was remarkably mild, as documented by data from 23 years of study including four cardiac catheterizations. At age 35 years, however, syncope, chest pain, and marked elevation of right ventricular pressure prompted complete surgical repair of the left and right ventricular outflow tract obstructions and closure of the septal defect. Three years after surgery the patient continues to lead an active life without symptoms. The unusually mild course can be attributed to the natural banding effects of the subpulmonic stenosis which prevented irreversible pulmonary hypertension.- - - - - - - - - - ranking = 1.6666666666667keywords = coronary (Clic here for more details about this article) |
9/26. coronary artery bypass grafting in dextrocardia with situs inversus totalis.dextrocardia with situs inversus totalis is a rare congenital abnormality of development involving a left-handed malrotation of the visceral organs. The incidence of coronary artery disease in this condition is probably similar to that in the general population. We report herein the case of a 62-year-old man with dextrocardia and situs inversus totalis who underwent myocardial revascularization by the use of right internal mammary artery and radial artery.- - - - - - - - - - ranking = 0.33333333333333keywords = coronary (Clic here for more details about this article) |
10/26. situs inversus and acute coronary syndrome.dextrocardia is a rare clinical phenomenon with a reported incidence of one in 10 000. Consequently, acute coronary syndromes in such patients are rare. When chest pain occurs in this setting, it is important to be aware of the unique problems that may occur if coronary intervention is contemplated. Previous case reports have shown successful attempts at reperfusing one coronary artery percutaneously. In this case, coronary stents were successfully deployed in two vessels of a man with situs inversus, which has not been reported before. Additionally, the angiographic results that followed from successful intervention did not produce the expected haemodynamic and electrocardiographic changes.- - - - - - - - - - ranking = 2.6666666666667keywords = coronary (Clic here for more details about this article) |
