OBJECTIVES: Concomitant surgical ablation of atrial fibrillation (AF) is recommended for patients undergoing off-pump coronary revascularization in the presence of this arrhythmia. Achievement of optimal visualization of pulmonary veins while maintaining stable haemodynamic conditions is crucial for proper completion of the ablation procedure. This study evaluates the safety and feasibility of right atrial positioning using a suction-based cardiac positioner as opposed to compressive manoeuvres for exposure during off-pump surgical ablation for AF...

It has been shown that inflammation and oxidative stress are important factors in postoperative atrial fibrillation (POAF). Angiotensin converting enzyme (ACE) and apelin have a close relationship with inflammation and oxidative stress. The effect of ACE and apelin on POAF after off-pump coronary artery bypass grafting (OPCABG) remains a question. The concentrations of serum ACE, angiotensin II (Ang II), apelin, bradykinin (BK), malondialdehyde (MDA), and C reactive protein (CRP) were measured in the perioperative period of OPCABG...

Transaortic approach represents an alternative variant of transcatheter aortic valve implantation (TAVI) which combines benefits of antegrade transapical approach and high safety profile characteristic of transfemoral approach. This method has substantial advantages over subclavian and transapical approaches in cases of pronounced myocardial hypertrophy, left ventricular dysfunction, thinning of left ventricular wall. We describe here a hybrid intervention with simultaneous coronary artery bypass grafting and TAVI in a patient from high surgical risk group with multivessel coronary artery involvement and critical aortic stenosis...

BACKGROUND: Coronary endarterectomy (CE) may be a good option for complete revascularization of diffuse coronary artery diseases, but it has not been widely used because the outcomes have not been definitively identified. This study aims to evaluate the mid-term clinical results of CE and compare the outcomes according to the use of cardiopulmonary bypass (CPB) and the surgical technique used. METHODS: Between 2004 and 2014, 69 cases of coronary endarterectomy were performed in 64 patients...

OBJECTIVE: By removing systematic differences across treatment groups, simple randomization is assumed to protect against bias. However, random differences may remain if the sample size is insufficiently large. We sought to determine the minimal sample size required to eliminate random differences, thereby allowing an unbiased estimation of the treatment effect. STUDY DESIGN AND SETTING: We re-analyzed two published multicenter, large and simple trials: the International Stroke Trial (IST) and the CORONARY study...

BACKGROUND Coronary artery bypass grafting (CABG) is a common procedure to circumvent the obstruction of coronary arteries when stents are unsuitable. CABG is a very traumatic surgery that requires redirecting blood flow to an external pump. Thus, this procedure has many risks during and after surgery, and minimizing these risks would greatly benefit the patients. MATERIAL AND METHODS We selected 126 patients with coronary artery syndrome and who were unsuitable for stent percutaneous coronary intervention...

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...
