Pulmonary arterial (PA) vasoconstriction in cardiac surgery can originate from the action of combined humoral, endothelial, and sympathetic tone changes. The consequence of PA vasoconstriction is pulmonary hypertension (PHT) and, when present after cardiopulmonary bypass (CPB), can predispose to right ventricular dysfunction. Right ventricular dysfunction after CPB is a serious ...

A case of isolated ventricular non-compaction associated to three-vessel disease and a mitral regurgitation is described. The patient underwent triple coronary artery bypass graft and restrictive mitral annuloplasty. The postoperative course was unsuccessful despite the very depressed left ventricular (LV) function. At two years follow-up, no major adverse cardiac event ...

BACKGROUND: Volatile anesthetics provide myocardial protection during cardiac surgery. Sevoflurane and desflurane are both efficient agents that allow immediate extubation after off-pump coronary artery bypass grafting (OPCABG). This study compared the incidence of arrhythmias after OPCABG with the two agents. MATERIALS AND METHODS: Forty patients undergoing OPCABG with immediate extubation ...

Right ventricular dysfunction occurs very soon after conventional coronary bypass surgery with cardiopulmonary bypass and might not recover within 1 year after the operation. It has been postulated that performing coronary surgery without cardiopulmonary bypass might preserve right ventricular function. We hypothesized that right ventricular global and overall systolic functions ...

Cardiopulmonary bypass (CPB) is widely used for cardiac surgery by virtue of its proven safety over the course of its use during the past half century. Even though perfusion is safer, incidents still occur. During the repair of a ventricular-septal defect in an 11-month-old infant, we experienced a critical incident ...

Approximately 10% of patients undergoing cardiac surgery have perioperative myocardial injury. A recent genome-wide association study identified an association between myocardial infarction in nonsurgical populations and common genetic variants on chromosome 9p21. We hypothesized that these variants are also associated with perioperative myocardial injury after isolated primary coronary artery bypass ...

Two features of off-pump coronary artery bypass (OPCAB) can lead to hemodynamic instability: transient occlusion of coronary arteries during distal anastomosis construction and displacement of the heart to provide access to distal coronary arteries. The position of the heart during OPCAB trans-esophageal echocardiography (TEE) can often provide an indication as ...

BACKGROUND: The calcium sensitizer levosimendan has anti-ischaemic effects mediated via the opening of sarcolemmal and mitochondrial ATP-sensitive potassium channels. These properties suggest potential application in clinical situations where cardioprotection would be beneficial, such as cardiac surgery. We thus decided to investigate whether pharmacological pre-treatment with levosimendan reduces intensive care unit ...
