Off-pump coronary artery bypass grafting in a high-risk dextrocardia patient: a case report

Total arterial revascularization in a case of dextrocardia with situs inversus

Dextrocardia and situs inversus with coronary artery disease poses unique challenges with respect to presentation and diagnosis. From a surgical point of view, the main decision-making revolves around the strategy of revascularization: the choice of right internal thoracic artery or the left internal thoracic artery for the left anterior descending artery anastomosis, the operating surgeon standing on the left or the right side of the operating table, and the choice of arterial or venous conduits. We report a case of total arterial revascularization using off pump coronary artery bypass technique in a case of dextrocardia with situs inversus using We discuss the various challenges involved in the diagnosis and management.

Off-Pump Triple Coronary Artery Bypass Grafting in a Patient with Situs Inversus Totalis: Case Presentation and a Brief Review of the Brazilian and the International Experiences

A 76-year-old man with situs inversus totalis underwent a successful off-pump three-vessel coronary artery bypass surgery. The postoperative course was uneventful, and the patient was discharged 8 days later. At 9-month follow-up a coronary computed tomography angiography confirmed the viability of all of the grafts, and one year after the operation the patient remained asymptomatic. It comprises the fifth Brazilian case of a coronary surgery in a patient with situs inversus totalis and the first one of the country of a coronary artery bypass surgery without the use of the cardiopulmonary bypass in this condition.

Coronary artery bypass surgery in a patient with Kartagener syndrome: a case report and literature review

Kartagener syndrome consists of congenital bronchiectasis, sinusitis, and total situs inversus in half of the patients. A patient diagnosed with Kartagener syndrome was referred to our department due to 3-vessel coronary disease. An off-pump coronary artery bypass operation was performed using both internal thoracic arteries and a saphenous vein graft. We performed a literature review for cases with Kartagener syndrome, coronary surgery and dextrocardia. Although a few cases of dextrocardia were found in the literature, no case of Kartagener syndrome was mentioned.

Should you stand on the left or the right of a patient with dextrocardia who needs coronary surgery?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was which side of the operating table you should stand on when carrying out surgical revascularization on a patient with dextrocardia. Altogether 40 papers were found using the reported search, of which 19 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes, and results of these papers are tabulated. The side on which the operating surgeon stood was mentioned in 20 out of the 24 cases. Surgery was carried out from the conventional right side of the patient in 5 cases, while in 10 cases, it was carried out from the left side. The surgeon needed to switch sides to facilitate surgery in three cases. In addition, the right internal mammary artery (RIMA) was anastomosed to the left anterior descending artery (LAD) in 16 cases. Of these, surgery was carried out from the left side in 11 cases. The left internal mammary artery (LIMA) to LAD anastomosis was carried out in two cases, one of which was a free LIMA graft. In six cases, only vein grafts were used. Fourteen cases were carried out using cardiopulmonary bypass while 10 cases were carried out as off-pump cases with one conversion. The majority of patients were operated on from the left of the table. More cases were performed with the RIMA as the conduit of choice to the LAD.
