The early results of coronary artery grafting with an aortic connector system were assessed in Japanese patients. From May 2002 through April 2003, 24 consecutive patients underwent off-pump coronary artery bypass using an aortic connector system. Another patient was excluded because the saphenous vein was insufficient for the smallest available aortic connector system. Saphenous veins were harvested from the thigh in 17 (70.8%) patients, and from the lower leg in 7. The size of the aortic connector system was 4.5-5.0 mm in 19 (79.2%) patients. Intraoperative epiaortic echo indicated that a side-clamp was contraindicated in 15 cases. Hemostasis was instantaneous in all patients. There were no hospital deaths and no neurologic morbidity. Pre-discharge angiography revealed 100% patency of the anastomoses. Use of the aortic connector system demonstrated excellent early results with low neurologic morbidity even when employed in the context of an atheromatous ascending aorta. However, smaller sizes of the device are required for some Japanese patients.

Article Synopsis
- Peripheral veno-arterial extracorporeal membrane oxygenation (ECMO) can save lives but may cause significant pulmonary edema in heart failure patients; this study highlights better outcomes with a novel central ECMO system that adjusts blood perfusion.!* -
- Analyzed 10 patients with severe heart failure and pulmonary edema treated using the RALV-AOPA ECMO, which provided optimized blood flow patterns and lower pulmonary arterial pressure, leading to improved heart function within 24 hours.!* -
- Six patients improved enough to be weaned off ECMO, while others received heart devices or transplants; all patients survived long-term with manageable complications, showcasing the central ECMO system's effectiveness in critical cases.!*
Apico-aortic conduit: a readily available technical modification.

When neither surgical valve replacement nor transcatheter aortic valve implantation is possible, performing an apico-aortic conduit remains a therapeutic option. This procedure has become rare and the rigid angled apical connectors usually used to facilitate ventricular anastomosis are no longer commercially available. We described the technique that we performed on a 60-year-old patient with readily available material.

Unlabelled: was to study the complex biomechanics of the aortic valve prosthesis and to analyze the effect of frame mobility on the stress-strain state and geometry of the valve leaflet apparatus using a numerical simulation method, which reproduces the qualitative and quantitative results of its bench tests.
Materials And Methods: The object of the study was a commercial valve bioprosthesis UniLine (NeoCor, Russia), a three-dimensional mesh of which was obtained on the basis of computer microtomography with a subsequent analysis of its stress-strain state in the systole- diastole cycle by the finite element method in the Abaqus/CAE medium. The simulation was validated by comparing the results of numerical and bench simulation on the ViVitro Labs hydrodynamic system (ViVitro Labs Inc.
Thrombosis in Extracorporeal Membrane Oxygenation (ECMO) Circuits.

From the Seattle Children's Hospital, Seattle, Washington.
Thrombosis in extracorporeal membrane oxygenation (ECMO) circuits remains a frequent complication. We characterize the location, extent, structure, and clinical implications of thrombi in 53 ECMO circuits from 46 pediatric patients. The tubing, pump, and oxygenator were examined for visible thrombi.

Abnormal congenital aorto-cardiac communications (CACC) are a heterogeneous constellation of anomalies that provide an abnormal connection between the aorta and other cardiac chambers or structures, including the atria, ventricles, the main pulmonary artery, and the coronary sinus. The current terminology of CACC has significant errors and shortcomings including inconsistent and interchangeable use of terms of fistula and tunnel and lack of an inclusive classification with practical information on therapeutic management. The aims of this study were threefold: firstly, to perform a concise narrative review of congenital pathologic connections between the aortic root and cardiac chambers which include rupture of congenital sinus of Valsalva aneurysm, aorto-left ventricular and less commonly right ventricular tunnels, coronary cameral fistulas, and aorto-atrial communications; secondly, to investigate the differentiating features of the so-called aorta right atrial tunnel (ARAT), with and without coronary artery take-off from the tunnel, and coronary cameral fistula (CCF) by applying a differential diagnostic assistance toolbox to two groups of patients with ARAT and CCF; and lastly, to propose a practical and inclusive anatomic-therapeutic classification for CACCs.
