In this article, the hemodynamic, humoral, and immunological perturbations following brain death (BD) are going to be discussed in a stepwise manner. ⋯ Delineation of the mechanisms responsible for donor heart dysfunction (DHD) would be presented. Furthermore, an attempt would be made to apply this knowledge into the clinical practice in order to increase the suitability of donor hearts for transplantation.

Case Reports
Unexpected persistent left superior vena cava and absent right superior vena cava in situs solitus patient.
We, herein, report a patient with persistent left superior vena cava with enlarged coronary sinus and absent right superior vena cava. This anomaly, diagnosed intraoperatively during the third open-heart surgery in the course of transesophageal echocardiography examination, was not mentioned during the patient's previous two cardiac operations. Challenges in intraoperative management and implications for subsequent treatments are discussed.

It is well known by now that during open heart surgery many detrimental factors are involved in lung injury. The influence mainly of cardiopulmonary bypass (CPB), anesthesia, hypothermia, operation itself, as well as medication and transfusion, can cause a diffuse injury in the lungs, which most often leads to a postoperative pulmonary edema and abnormal gas exchange. ⋯ In this review we highlight the possible pathophysiological mechanisms implicated in the observed postoperative lung dysfunction.

Heterogeneous double cardiac tumor is rarely encountered. We present a case of simultaneous resection of myxoma and papillary fibroelastoma. ⋯ Pathohistologic examination confirmed the diagnosis. We discuss the echocardiographic characteristics and preferred surgical approaches for the two tumors.

Kommerell's diverticulum of an aberrant left subclavian artery associated with a right-sided aortic arch is a rare congenital aortic anomaly. This communication reports two cases of this congenital anomaly leading to severe dysphagia. Both cases were successfully repaired with a staged open approach rather than an endovascular approach, which would not have addressed the presenting symptom of dysphagia.
