The performance of coronary bypass surgery without cardiopulmonary bypass (“off pump”) may reduce perioperative morbidity and costs, but it is uncertain whether the outcome is similar to that ...

Coronary-artery bypass grafting (CABG) has traditionally been performed with the use of cardiopulmonary bypass (on-pump CABG). CABG without cardiopulmonary bypass (off-pump CABG) might reduce the ...

Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

Bypass surgery done without a heart-lung machine, known as off-pump, may provide better post-operative outcomes than on-pump bypass surgery for high-risk patients, according to new research. Bypass ...

In August’s column, I discussed three-way control valves, their associated bypass pipes, and the importance of a balancing valve being located within the bypass pipe. Such balancing valves are needed ...

Coronary artery bypass surgery is a procedure to treat coronary heart disease. There are various types, including multiple bypass and minimally invasive. The medical name for coronary artery or heart ...
