BACKGROUND Myocardial revascularization in patients with renal insufficiency is challenging to the cardiac surgeon, irrespective of utilizing extracorporeal circulation. This study aimed to compare the number of bypass grafts and the mid-term results and to evaluate independent survival predictors in patients with renal insufficiency undergoing on-pump or off-pump myocardial revascularization. ...

We examined whether transmyocardial revascularization (TMR) relieves myocardial ischemia by increasing regional perfusion via the transmural channels in acute canine experiments. Regional blood flow during transient coronary ligation (2 min) was compared before and 30 min after TMR, and at the third transient ischemia the mid-left ventricle (LV) was cut and immediately frozen along the short ax...

background: the aim of the present study was to develop a scoring system for predicting 1-year major adverse cardiac events (mace), including mortality, target vessel or target lesion revascularization, coronary artery bypass graft surgery, and non-fatal myocardial infarction after percutaneous coronary intervention (pci). methods: the data were extracted from a single center pci registry. the ...

INTRODUCTION Prognosis after opening the obstructed coronary artery in acute myocardial infarction (AMI) is influenced by several factors. In routine clinical practice, revascularization is considered to be successful when the restoration of epicardial blood-flow is complete. However, the patent epicardial artery does not always provide functional recovery in the myocardium. There are two visua...

Rational management of patients with coronary artery disease (CAD) and poor left ventricular (LV) function relies on proper identification of the subgroup at high risk and those who have the highest potential of benefiting from a particular type of treatment. Before the advent of imaging techniques to determine myocardial viability, many patients with CAD and low ejection fractions (EFs) were r...

OBJECTIVE To identify risk factors for acute myocardial infarction during the postoperative period after myocardial revascularization. METHODS This was a case-control study paired for sex, age, number, type of graft used, coronary endarterectomy, type of myocardial protection, and use of extracorporeal circulation. We assessed 178 patients (89 patients in each group) undergoing myocardial rev...

Complete arterial revascularization for the right coronary artery is underused mainly due to technical issues. Herein we report on a new approach for complete arterial revascularization of arterial revascularization for the right coronary artery branches. Complete arterial revascularization for the right coronary artery revascularization was performed in 8 patients using a reverse T composite a...

In this case, we describe a 33-year-old man presenting with acute mesenteric ischemia. When we searched for a source of embolism, a giant right atrial mass and patent foramen ovale was discovered. Standard electrocardiography showed signs of an old, silent anteroseptal wall myocardial infarction, confirmed by echocardiography and left ventriculography. Coronary angiography revealed complete occ...

BACKGROUND Diabetic patients are a group of primary interest in the study of myocardial revascularization. AIM To compare coronary artery bypass grafting surgery (CABG) and percutaneous angioplasty with stents (PCI-S) in diabetic patients with coronary three-vessel or left main coronary artery disease. MATERIAL AND METHODS Meta-analysis of MEDLINE randomized controlled studies comparing CAB...

Within 30 days of acute myocardial infarction, 108 consecutive patients underwent urgent surgical myocardial revascularization for postinfarction angina between July 1976 and March 1983. There were 84 men and 24 women whose mean age was 59.6 +/- 9.5 years (range 34 to 80). Group I (15 patients, 14%) underwent surgery within 48 hours, Group II (47 patients, 43%) between 3 and 7 days and Group II...
