Midterm results of left coronary artery reimplantation through the transverse sinus of the pericardium in adult Bland-White-Garland syndrome

The anomalous origin of the left coronary artery from the pulmonary artery - known as Bland-White-Garland syndrome - is a rare congenital malformation that affects 1 in 300,000 live births. Most patients die in infancy without any surgical treatment. Some patients who survive past childhood often have varying symptoms such as myocardial ischemia, impaired left ventricular function, mitral regurgitation, and progressive heart failure, depending on the development collateral circulation. In the present report, we describe a procedure wherein the left coronary artery ostium was translocated through the transverse sinus of the pericardium in a 43-year-old mother with Bland-White-Garland syndrome and concomitant mitral regurgitation and report on the associated midterm results

Reversed L-shaped incision for resection of a large azygos vein aneurysm: a case report

Abstract Background Azygos vein aneurysms are rare and asymptomatic in many cases. The management for these aneurysms is controversial, and there is no clear guideline or evidence-based threshold for surgical or interventional therapy. Case presentation Herein, we report the case of a giant azygos vein aneurysm in a 78-year-old man that was treated with a reversed L-shaped incision. A 56 × 77 mm saccular azygos vein aneurysm was incidentally detected on computed tomography. Subsequently, surgical resection with interventional radiology and reversed L-shaped thoracotomy was performed. First, we performed coil embolization of the azygos vein aneurysm inflow. Next, a cardiopulmonary bypass was established through a reversed L-shaped sternotomy, and the aneurysm was excised. Conclusions In this case, surgical resection via reversed L incision was effective

Self-align fabrication of nano-reservoir with NV center in diamond surface for nuclear magnetic resonance of small molecules

We propose a novel structure to confine small molecules in a nanoscale reservoir and perform nano-NMR with a single NV center created near the reservoir base. We also propose a self-align process to fabricate the nano-reservoir and the single NV center adjacently in the diamond surface using electron beam lithography, nitrogen ion implantation and oxygen plasma etching. In this paper, we discuss the feasibility of the nano-NMR using nano-reservoirs in terms of the damage induced in the diamond by dry etching, the detection volume (i.e. the implantation depth) and the electron spin coherence property of the NV center.32nd International Microprocesses and Nanotechnology Conferenc

New Delta Doping of Nitrogen for 2 Dimensionally Condensed NV C enter s Using Nitrogen Terminated Diamond Followed by High Purity Diamond Growth

We have successfully made 2 dimensionally condensed NV centers from N-terminated (111) diamond with near monolayer coverage. The N on the surface has been em-bedded by high purity homoepitaxial (111) diamond film to form NV centers. The NV centers made by these tech-niques were highly aligned. This new method of fabricat-ing NV centers is useful for application of NV centers to more sensitive quantum sensors.2019 International Conference on Solid State Devices and Material
