Twelve patients with refractory myocardial failure following open heart surgery were treated with a temporary left (10), right (1) or biventricular (1) assist circuits driven by extracorporeal pumps. Ten of 11 patients were weaned from the pump oxygenator. During left ventricular assist, maximal pump flow was 2.2 +/- 0.6 l/min per m2 at a cardiac index of 2.5 +/- 0.9 l/min per m2. Diuresis was ...

Pump failures are an inherent problem associated with the operation of a heart lung machine. This report details the observation and identification of an unusual modular pump failure. Pump stoppage occurred intermittently over a period of two months with two separate Stockert/Shiley Computer Aided Perfusion System (CAPS) consoles. The mechanism was identified as a static discharge transferred t...

Water is the most essential component for sustaining lives of humans and other living creatures. Supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. But sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. Th...

OBJECTIVES To evaluate incidence, mortality, and risk factors related to the development of acute renal failure (ARF) after on-pump coronary artery bypass grafting (CABG), between January 2002 and November 2004. METHODS Seventy four patients who underwent on-pump CABG were analyzed retrospectively and distributed into two groups according to the development of ARF. Bivariate and multivariate ...

Left ventricular assist devices (LVADs) are increasingly used for the treatment of end-stage congestive heart failure, both as a bridge to transplantation and as destination therapy (1). The HeartWare HVAD (HeartWare Inc, Framingham, MA, USA) is a continuous centrifugal-flow left ventricular assist device with a magnetic levitating rotor pump. The pump weighs just 140 g and its small design all...

The twin reversed arterial perfusion (TRAP) sequence is a rare complication of 1% of monochorionic twin gestation with an incidence of 1 in 35,000 births. One twin is structurally normal while the other is abnormal with development of legs and lower body and undeveloped thorax, head and heart. The abnormal twin also referred as Acardiac monster twin receives its blood supply from normal or the ...

OBJECTIVES The purpose of this study was to test the ability of cardiopulmonary exercise testing (CPET)-derived variables as sudden cardiac death (SCD) predictors. BACKGROUND The CPET variables, such as peak oxygen uptake (VO2), ventilatory requirement to carbon dioxide (CO2) production (VE/VCO2) slope, and exercise oscillatory breathing (EOB), are strong predictors of overall mortality in ch...

BACKGROUND It has been well documented that women have higher morbidity and mortality rates than men following coronary artery bypass graft (CABG) surgery. In view of this evidence, it is necessary to know if there is benefit to off-pump CABG surgery in women in comparison to on-pump CABG. OBJECTIVES Compare outcomes between off-pump CABG and on-pump CABG in women. METHODS Retrospective stu...

The kinetic characteristics of the Na:K pump in high potassium (HK) and low potassium (LK) goat red cells were investigated after altering the intracellular cation concentrations. At low concentrations of intracellular K (K(c)), increasing K(c) at first stimulates the active K influx in HK cells, but at higher K(c) the pump is inhibited. These results suggest that in HK cells K(c) acts both at ...
