We present the case of a type AB thymoma in a 69-year-old man with previous coronary artery bypass grafting (CABG) in whom angiography revealed a left internal mammary artery graft supplying blood flow to a thymic neoplasm, which simultaneously occluded the graft. This required a redo sternotomy, lysis of pericardial adhesions, complete thymectomy, and redo one vessel off-pump CABG. This case seeks to sensitize physicians to the possibility of coronary adverse events in patients with a previous CABG in the setting of management of mediastinal neoplasms, and it presents the novel findings on cardiac imaging associated with this case...

The porcine model is a commonly used animal model in cardiovascular research. Along with new innovative operative techniques, choice of the optimal imaging technique is crucial. Transesophageal echocardiography (TEE) is a reliable imaging tool is highly important in a large number of experimental evaluations. But so far, TEE data for swine are limited, and few standard values have been established for the porcine model. The experience and baseline results for TEE in 45 swine are presented in this study. A full TEE examination was conducted in 45 German landrace or German large white swine, with an average body weight of 49 ± 3 kg, before experimental off-pump mitral valved stent implantation...

Mediastinal radiation is commonly used to treat Hodgkin's and non-Hodgkin's lymphoma, lung and breast cancer. Cardiac complications after radiation therapy are well described, although rare. A large spectrum of injuries can occur, causing long term morbidity among survivors. We describe a case of post-actinic ascending aortic wall thickening that prevented saphenous vein proximal anastomosis and was successfully managed with aortic no-touch off-pump coronary artery bypass grafting (OPCAB), 25 years after radiation therapy for Hodgkin's lymphoma...

The release of myocardial necrosis biomarkers after off-pump coronary artery bypass grafting (OPCAB) frequently occurs. However, the correlation between biomarker release and the diagnosis of procedure-related myocardial infarction (MI) (type 5) has been controversial. This study aimed to evaluate the amount and pattern of cardiac biomarker release after elective OPCAB in patients without evidence of a new MI on cardiac magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE).Patients with normal baseline cardiac biomarkers referred for elective OPCAB were prospectively included...

Although randomized clinical trials have compared the short-term results of coronary revascularization with on-pump vs. off-pump, the long-term survival effect of off-pump coronary surgery has not been analyzed. The aim of this study was to compare the long-term survival of patients with coronary surgery with off-pump technique. All patients that underwent coronary revascularization from November 1996 to March 2015 were included (n = 4687). We analyzed the long-term survival and the incidence of cardiac events between patients who received off-pump coronary revascularization (n = 3402) against those revascularized with on-pump technique (n = 1285)...

Since the 1990s, a large body of literature has been published regarding minimally invasive coronary artery bypass grafting. Varying techniques, complexity of the procedures and the necessity of patient selection have led to its inconsistent application. We describe the standardized technique of left internal mammary artery grafting to the left anterior descending coronary artery, off-pump through a left inferior J-hemisternotomy (JOPCAB). This approach is straightforward, safe, effective, and replicable in virtually all patients...
