Retrograde coronary sinus perfusion is a technique being used to deliver cardioplegia during cardiac surgery. This article reviews the history behind its use, the procedure for delivery, and the advantages and limitations that exist in comparison with the standard antegrade infusion of cardioplegia via the aortic root. The complications resulting from the technique of retrograde coronary sinus perfusion are rare. Nursing considerations specific to the potential complications of this patient population are discussed.

The aim of this study was to describe the features of myocardial lymph flow using a new combined method of visualization of the lymphatic system. The study was performed on pig hearts harvested from a local slaughterhouse. The original dye, consisting of lipid-soluble chlorophyll and lipiodol, was injected stepwise into the lymphatic vessels.

Endoscopic retrograde cholangiopancreatography (ERCP) training remains challenging. This study used 3D printing techniques to develop and optimize a portable ERCP training simulator and to implement basic and advanced practical techniques. Subsequently, we aimed to determine whether endoscopy trainees acquired proficiency in ERCP techniques and assess any improvements in their skill levels from using this model.

Objective: The pyeloureteral anastomosis remains the most challenging part of pyeloplasty. A purpose-built anastomotic device could simplify this step and potentially improve outcomes. The concept of a pyeloureteral magnetic anastomosis device (PUMA) was proven in minipigs, but only in short term.

Background: Left ventricular assist device (LVAD) has been widely used as an alternative treatment for heart failure, however, aortic regurgitation is a common complication in patients with LVAD support. And the O-A angle (the angle between LVAD outflow graft and the aorta) is considered as a vital factor associated with the function of aortic valve. To date, the biomechanical effect of the O-A angle on the aortic valve remains largely unknown.

Coronary sinus (CS) defects are rare congenital cardiac anomalies that occur in isolation or with other congenital heart diseases. Persistent left superior vena cava (LSVC) is a relatively common entity that usually drains into the CS, is of no hemodynamic consequence, and is easily diagnosed on echocardiography by a dilated CS and an antegrade flow toward the heart. However, a combination of LSVC and CS defect may reverse its flow direction and CS dilation may be absent.
