Del nido cardioplegia in adults: a retrospective observational study in comparison to modified St. Thomas cardioplegia in cardiac surgery.

Background: St. Thomas cardioplegia is commonly administered to adults, yet repeated dosing at brief intervals is required. Del Nido's cardioplegic solution provides a prolonged duration of safe myocardial arrest, yet it was primarily intended for pediatric cardiac surgery.

Goal-directed therapy improves the outcome of high-risk cardiac patients undergoing off-pump coronary artery bypass.

Background: There has been a constant emphasis on developing management strategies to improve the outcome of high-risk cardiac patients undergoing surgical revascularization. The performance of coronary artery bypass surgery on an off-pump coronary artery bypass (OPCAB) avoids the risks associated with extra-corporeal circulation. The preliminary results of goal-directed therapy (GDT) for hemodynamic management of high-risk cardiac surgical patients are encouraging.

Perioperative utility of goal-directed therapy in high-risk cardiac patients undergoing coronary artery bypass grafting: "A clinical outcome and biomarker-based study".

Goal-directed therapy (GDT) encompasses guidance of intravenous (IV) fluid and vasopressor/inotropic therapy by cardiac output or similar parameters to help in early recognition and management of high-risk cardiac surgical patients. With the aim of establishing the utility of perioperative GDT using robust clinical and biochemical outcomes, we conducted the present study. This multicenter randomized controlled study included 130 patients of either sex, with European system for cardiac operative risk evaluation ≥3 undergoing coronary artery bypass grafting on cardiopulmonary bypass.

Asymptomatic type B right atrial thrombus in a case with protein S deficiency.

Thirty seven year old asymptomatic male underwent routine medical examination which revealed an abnormal mass in the right atrium. Family history was not suggestive of any cardiac or malignant disease. Detailed investigation detected deficiency of protein S, which is a vitamin K dependent protein and a cofactor for activated protein C mediated cleavage of factor Va and VIIIa.

Coronary artery bypass surgery in the presence of cerebrospinal fluid rhinorrhea.

A seventy eight year old male patient was admitted in our hospital with headache, vomiting, irritability and confusion. Initially he was diagnosed as a case of pyogenic encephalitis. Further investigations revealed that patient had cerebrospinal fluid rhinorrhea and coronary artery disease.
