Cardiac maneuvering during off-pump coronary artery bypass surgery can compress the right ventricle, causing temporary dysfunction and hemodynamic instability. The hemodynamic impact of a decompression technique comprising right pleurotomy and pericardial release was investigated during cardiac elevation. Intraoperative continuous real-time monitoring of cardiac index and stroke volume index was carried ...

Thiamine is an essential component of cellular metabolism, and lack of this vitamin results in a potentially life-threatening biochemical lesion. The stress of surgery and critical disease depletes electrolytes, minerals, and essential biochemical substrates. We hypothesized that critical illness (represented by major surgery) would result in decreased thiamine levels over ...

Cardiac allograft vasculopathy is a severe complication after heart transplant, and is the major cause of death in patients surviving 1 year after transplant. We present a 59-year-old patient undergoing off-pump, coronary artery bypass surgery, 8 years after heart transplant. Owing to toxic liver disease, the lipid lowering therapy with ...

Heparin-induced thrombocytopenia (HIT) is a rare immune-mediated complication of heparin administration. A potentially life-threatening complication, HIT is difficult to diagnose in patients in the intensive care unit after cardiac surgery because there can be multiple reasons for thrombocytopenia. Moreover, immune-mediated platelet consumption may be masked by reactive thrombocytosis, which is ...

BACKGROUND: True lung injury is among the leading causes of transfusion-related mortality. Pulmonary morbidity after cardiac surgery has been related to damaging effects of cardiopulmonary bypass and transfusion, but is confounded by cardiac-related events that may not reflect true lung injury. Thus, cardiac surgery poses unique challenges to criteria-specific diagnosis ...

Delirium is an acute change in cognition which occurs frequently after coronary artery bypass graft (CABG) surgery. Cerebral microemboli, from plaque, air, or thrombus, have been hypothesized to contribute to delirium and cognitive decline after CABG. The purpose of this study was to determine if there was an association between ...

Atrial fibrillation (AF) is the most common adverse event following coronary artery bypass graft surgery. A recent study identified chromosome 4q25 variants associated with AF in ambulatory populations. However, their role in postoperative AF is unknown. We hypothesized that genetic variants in the 4q25 chromosomal region are independently associated with ...

Uncalibrated arterial waveform analysis (FloTrac/Vigileo) uses standard arterial access to determine cardiac output (CO). Calculations are based on arterial waveform characteristics in combination with patient characteristic data to estimate individual arterial compliance. It has been shown that obesity is associated with altered arterial compliance independently of other risk factors. We ...

The authors prospectively compared three techniques of continuous cardiac index measurements. They were, invasive Continuous Cardiac Index using thermodilution flow-directed Swan-Ganz pulmonary artery catheters, semi invasive Flotrac-arterial pressure derived cardiac index and the non invasive cardiac index measurement-body impedance plethsmography. The cardiac index measurements were made simultaneously in the postoperative ...

Residual left-sided valvular insufficiencies after valvular surgery may confound transpulmonary thermodilution cardiac output (COtp). We compared the technique with the continuous right-sided thermodilution technique (CCO) after valvular surgery (n=8) and coronary artery surgery (n=8). Patients with pulmonary and femoral artery catheters in the intensive care unit (ICU) were included. After ...
