Dextro-transposition of the great vessels associated with pulmonary stenosis, double-outlet right ventricle, and straddling of the tricuspid valve is an uncommon condition. Several treatment options are available for this malformation, but most of them are not optimal. For patients with transposition of the great vessels, the gold standard procedure, which is an arterial switch procedure, would usually be performed, whereas for patients with pulmonary stenosis, a Rastelli operation or a Nikaidoh procedure would be proposed. Both of these methods have several advantages and disadvantages. Selected patients can qualify for the double-root rotation procedure, which is limited by the function of the pulmonary and aortic valves, the position of the coronary arteries, and the skill of the surgeon[1]. After a thorough analysis of all the preoperative test results, our patient qualified for a surgical correction of the malformation. Due to preexisting pulmonary regurgitation and severe dilation of the pulmonary root, the patient was not considered a good candidate for the arterial switch operation. Therefore, it was decided that the double-root inversion was the best option. Introduction The double-root inversion gives the patient the possibility of avoiding a reoperation. If the patient were to have the Nikaidoh or the Rastelli procedure, we know that the pulmonary graft would eventually have to be replaced. For this reason, we would like to share our experience with the double-root inversion method.

"Micro-Bentall" procedure.

Multimed Man Cardiothorac Surg 2020 12 24;2020. Epub 2020 Dec 24.

University Hospital of Geneva University Hospital of Laussane Switzerland.

Truncus arteriosus, an anomaly of the conotruncus, is an extremely rare congenital heart disease that affects 1.19% of all patients with congenital heart diseases.  We present a surgical technique using an 8-mm cryopreserved aortic root homograft in the aortic position and a 12-mm pulmonary valved conduit in the right position that allowed us to correct this rare congenital malformation.  The cryopreserved aortic root homograft was considered a priority option for surgical correction.  The neonatal Bentall (micro-Bentall) procedure is a surgically demanding procedure but can be performed successfully by an experienced surgeon.  If we were performing a non-salvage procedure, we would have chosen a decellularized allograft.

Incidental diagnosis of a silent brachiocephalic vein aneurysm and its surgical treatment.

J Vasc Surg Cases Innov Tech 2020 Mar 4;6(1):21-23. Epub 2020 Feb 4.

Division of Cardiovascular Surgery, Department of Surgery, Geneva University Hospitals and Faculty of Medicine, Geneva, Switzerland.

Brachiocephalic vein aneurysm is an extremely rare clinical entity, with a limited number of case reports in the literature. We report the case of a 74-year-old woman with a left brachiocephalic vein aneurysm (3 × 3 × 6.5 cm) that was discovered fortuitously by contrast-enhanced chest computed tomography. Surgical intervention was performed simultaneously during tricuspid valve surgery with coronary artery bypass grafting. This paper discusses the details of our case, the surgical treatment of brachiocephalic vein aneurysms, and the different treatment options.
