BACKGROUND Avoiding cardiopulmonary bypass in coronary artery bypass grafting is thought to reduce early mortality and morbidity. METHODS We used our prospective database to compare all patients having off-pump coronary surgery (n = 389) with those having on-pump coronary surgery (n = 2412) between March 15, 1995, and November 1, 2000. Patients were grouped by age (years) in decades (>90, 80-...

Background/Introduction Acute kidney injury (AKI) occurs in up to 30% of patients undergoing coronary artery bypass grafting. Development of kidney injury is associated with high overall mortality and a more complicated hospital course. Cardiopulmonary bypass is considered as one of the major risk factors for developing AKI. Off-pump coronary artery bypass (OPCAB) grafting eliminates the need f...

Abstrad------------------Hemofiltration during or after cardiopulmonary bypass has proved to be an efficient tool for hemoconcentration. Classically, the hemofilters are supplied by the arterial line and the filtration rate is mainly a function of the perfusion pressure. We have developed a convertible cardiopulmonary bypass system including a double head roller pump for blood cardioplegia appl...

We report a 66-yr-old male patient who developed tricuspid regurgitation secondary to internal cardiac massage. After uneventful off-pump coronary artery bypass surgery, the subject experienced cardiac arrest in the intensive care unit. External cardiac massage was initiated and internal cardiac massage was performed eventually. A transesophageal echocardiography revealed avulsion of the anteri...

This centrifugal pump (CP) includes two parts: the blood pump and the driving apparatus. They are connected by six twin magnetic disc plates and driven by a magnetic DC motor (120W). The blood pump had six leaves deadlocked between two plastic discs. Six leaves were set at 30 degrees angles, separately. In the lower chamber of the CP, there was an inlay magnetic disc, which is connected with th...

Results Age, diabetes, preoperative renal insufficiency, and prolonged cardiopulmonary bypass time (CPB) were the independent predictive factors of postoperative renal insufficiency in patients undergoing on-pump coronary revascularization. Postoperative mortality rate was 12.5% (no = 1) and 47.4% (n = 27) in patients with postoperative renal insufficiency undergoing off-pump and onpump coronar...

CABG being one of the most common types cardiac surgery, lowers risk Myocardial Infarctions and patients can remain symptom free for as long 10-15 years. Though this surgery became more common, there are 2 methods performing CABG, they On-pump Off-pump techniques. Recent studies reveals several advantages technique than technique. So intention study was to analyze if is anyphysiological signifi...

Background: Lactic acidosis in cardiac surgical patients is a manifestation of systemic inflammation and excess pro-inflammatory cytokine production. This investigation was designed to integrate basic concepts about lactate acidosis with a clinically used of serum lactate in patients under coronary artery bypass surgery (CABG) by on pump method. Methods: From August to September 2012, 15 patie...

A 69-year-old woman with angina had a lesion in the left lower lobe on chest film. Angiography revealed coronary artery disease in three vessels. Combined off pump coronary artery bypass grafting (CABG) and left lower lobectomy were performed through median sternotomy. This approach avoids complications due to staged operations and cardiopulmonary bypass (CPB). This report shows that simultaneo...

Background. Conventional coronary artery bypass surgery has been associated with cerebral injury attributed to cardiopulmonary bypass (CPB) and surgical manipulation of the ascending aorta. Off-pump coronary artery surgery avoids these factors and could prevent cerebral injury. However, moving the heart from its natural position affects the circulation and could compromise cerebral oxygenation ...
