Acute right ventricular failure is caused by inadequate right ventricular hypothermia

Pre‐ and Postoperative Quantitation of Right Ventricular Tissue Doppler Velocities in Infants with Hypoplastic Left Heart Syndrome

“…The relationship of systolic RV velocity to inotropic support is not documented in the literature and that of left ventricle velocity has been debated. 11,12 The negative effects of cardiopulmonary bypass on RV function have been widely reported; [13][14][15] however, Stein et al reported a recovery of RV function after initial depression due to cardiopulmonary bypass within 24 hours. 16 In our patient population, all patients showed a significant decline in tissue Doppler systolic and diastolic velocities from the preoperative to the postoperative period, quantitatively indicating that clinical postoperative recovery occurs despite severe decrease in systolic and diastolic function.…”

Severe right heart failure after heart transplantation. A single-center experience

“…Different additional intraoperative risk factors can lead to early postoperative RHF and should therefore be considered in heart transplantation. Numerous studies evaluating different preservation solutions, influence of the duration of cold and warm ischemia and influence of PEEP in the recipient have been performed [4,16–21]. Patients might benefit from consideration of these results and therefore carefully chosen preservation solutions and well established surgical techniques to reduce duration of ischemia are believed to be mandatory in heart transplantation.…”

Atrial natriuretic peptide and N‐terminal atrial natriuretic peptide in plasma reflect right ventricular volumes following coronary artery surgery

“…Transient RV dysfunction of varying degrees is common after CABG surgery (17,24). Preservation of RV integrity during cardiac surgery is more difficult than left ventricular protection (15)(16)(17). Patients with severe RCA stenosis are at increased risk of developing RV ischaemia and dysfunction perioperatively, this manifesting itself in a decrease in RVEF (18,19), as also seen in our study later postoperatively, when RVEF in the RCA-diseased patients was still below the baseline but had recovered in the controls.…”

“…The protection of the right ventricular (RV) myocardium during ischaemia induced by aortic clamping in cardiac surgery is limited because RV hypothermia is more difficult to achieve and maintain (15)(16)(17). The problem is emphasized when the right coronary artery (RCA) is diseased (18,19).…”
