Percutaneous coronary intervention (PCI) is actually the most used method of revascularization. Although complete revascularization remains a desirable goal, it may not be possible or not easy to plan in many patients. Thus, incomplete revascularization might be a preferred treatment strategy in selected patient categories. Stress myocardial scintigraphy, because of its high diagnostic accuracy...

Near-maximal treadmill exercise tests (TET) performed at the time of coronary arteriography and bypass graft visualization an average of 13 months after direct myocardial revascularization were analyzed in 217 consecutive patients to assess the accuracy of the TET in predicting completeness of revascularization. TET results were correlated with bypass patency and extent of revascularization. Al...

The natural history of aneurysms of the major arteries after revascularization in moyamoya disease has yet to be documented. At our institute, we treated two patients with moyamoya disease-associated aneurysms involving major arteries of the posterior cerebral circulation. The aneurysms became enlarged at an early stage after revascularization, necessitating coil embolization. Although cerebral...

OBJECTIVES The aim of this study was to evaluate the impact of coronary artery calcium (CAC) burden and regional distribution on the need for and type of future coronary revascularization-percutaneous versus surgical (coronary artery bypass graft [CABG])-among asymptomatic subjects. BACKGROUND The need for coronary revascularization and the chosen mode of revascularization are thought to be f...

The impact of a coronary revascularization strategy (early or deferred) on clinical outcomes of non-ST-segment elevation acute coronary syndrome (NSTE-ACS) has not been well established. The goal of this study was to systematically review randomized trials comparing early to deferred revascularization for NSTE-ACS. A systematic literature search of MEDLINE, ISI Web of Science, and Cochrane data...

Background—In 1995, the Bypass Angioplasty Revascularization Investigation (BARI) found that patients with diabetes had a survival benefit when treated with surgical revascularization versus balloon angioplasty, prompting a National Heart Lung and Blood Institute (NHLBI) “Clinical Alert.” The influence of the BARI findings and of the Clinical Alert on practice patterns is unknown. Methods and R...

With the advent of direct bypass surgery, the dramatic clinical responses in some patients has been followed by enormous enthusiasm in many centers. Surgical technics have advanced to such a point that nearly all patients with obstructive coronary disease could have the obstructions bypassed to one or many areas. Criteria for evaluating surgery include mortality, operative infarction rate, pate...

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. ...
