[...]Guangqing et al. study does not discuss the hemodynamic management protocol employed in their setting [1]. [...]the lack of account for low cardiac output syndrome (LCOS) incidence or intra-aortic balloon pump (IABP) use merits attention, particularly amidst Yi et al. delineating postoperative LCOS and intraoperative IABP use as important CSA-AKI predictors (OR; 95% CI; p value: 2.30; 1.05–5.04; 0.04 and 4.44; 2.37–8.30; < 0.00001, respectively) in a meta-analysis including 2157 cases and 49,777 controls [4]. [...]Guangqing et al. additionally overlook the contextual vasopressor-inotropic requirements. [...]the absence of blood-transfusion and glucose-homeostasis regimen in the Guangqing et al. study is also difficult to neglect when perioperative transfusions and glycemic fluctuations have been linked to an accentuated risk for CSA-AKI [1, 6, 7] While parsimonious inflammatory prognostication is indeed a welcome inclusion to the risk-stratification repertoire [8], a comprehensive approach is pivotal to a sound understanding of the research subject.

Williams-Beuren syndrome is a rare genetic malformation with predilection for supravalvular aortic stenosis. Apart from cardiovascular malformation, hypocalcemia, developmental delay, and elfin facies, challenging airway make perioperative management more eventful. Association of infective endocarditis within the aortic arch and pseudoaneurysm formation is infrequent. We, hereby report a case of pseudoaneurysm formation and infective vegetation within the aortic arch in a patient with Williams syndrome and the role of transthoracic echocardiography in its perioperative management.

The perioperative period induces unpredictable and significant alterations in coronary plaque characteristics which may culminate as adverse cardiovascular events in background of a compromised myocardial oxygen supply and demand balance. This \"ischemic-imbalance\" provides a substrate for perioperative cardiac adversities which incur a considerable morbidity and mortality. The propensity of myocardial injury is dictated by the conglomeration of various factors like pre-existing medical condition, high-risk surgical interventions, intraoperative hemodynamic management, and the postoperative care. Perioperative myocardial infarction (PMI) differs from myocardial infarction (MI) in a non-operative setting. PMI can often be notoriously \"silent\" demonstrating a conspicuous absence of the classic clinical symptoms. Moreover, myocardial injury following non-cardiac surgery (MINS) characterized by an elevation of the cardiac insult biomarkers has demonstrated an independent prognostic significance in the perioperative scenario despite the lack of a formal categorization as PMI. This has evoked interest in the meticulous characterization of MINS as a discrete clinical entity. Multifactorial etiology, varying symptomatology, close differential diagnosis, and a debatable management regime makes perioperative myocardial injury-infarction, a subject of detailed discussion.

Background: Prophylactic use of intra-aortic balloon pump (IABP) mainly depends on left ventricular (LV) systolic function. Global longitudinal strain (GLS) is a robust prognostic parameter for LV strain. It has proved to be more sensitive than LV ejection fraction (EF) as a measure of LV systolic function and is a strong predictor of outcome. Aim: To determine whether GLS can be used as a reliable marker and its cut-off value for IABP insertion in patients undergoing elective off-pump coronary artery bypass grafting (OPCABG). Settings and Design: A prospective observational clinical study which included 100 adult patients scheduled for elective OPCABG. Materials and Methods: Two-dimensional (2D) speckle tracking echocardiography (STE)-estimated GLS was computed and compared with LV EF measured by three dimensional (3D) echocardiography for the insertion of IABP. The intensive care unit (ICU) parameters were correlated with echocardiographic parameters to predict early post-operative outcome. Results: IABP insertion correlates better with GLS (post-revascularization > pre-revascularization) than with 3D LV EF. Receiver operating characteristic (ROC) curve analysis revealed the highest area under the curve (AUC, 0.972) with a cut-off value of > -9.8% for GLS compared to 3D LV EF (AUC, 0.938) with a cut-off value of ≤ 44%. ICU parameters show better correlation with E/e'> GLS > WMSI than 3D LV EF. Conclusion: GLS is a better predictor of IABP insertion compared to 3D LV EF in patients undergoing OPCABG.

[...]we miss the account on the comparison of renal outcomes in the Rösler et al.1 evaluation. [...]given postoperative stroke was an important outcome under consideration in the analysis of Rösler et al.1, the absence of intergroup matching for the prevalence of carotid artery stenosis as well as incidence of postoperative atrial fibrillation (POAF) is difficult to overlook. [...]the description of the corresponding transfusion requirements in the on-pump and of-pump groups would have further consolidated the comparative perspective of the study by Rösler et al.1.

Pseudoaneurysm of the common carotid artery (CCA) is exceptionally unstable and unpredictable; it mandates quick medical attention in order to circumvent neurologic sequelae or hemorrhage. Unanticipated rupture is extremely lethal and a potential provocation for the anesthesia caregiver. It is an arduous challenge for an anesthetist to establish emergency airway when a huge bleeding pseudoaneurysm is compressing and deviating the trachea, securing invasive lines in collapsing vessels, volume and vasopressor resuscitation in deteriorating hemodynamics in order to maintain cerebral perfusion without compromising other vital organs, arranging huge amount of blood and blood products in a short span of time, and transferring an exsanguinating patient for the rapid institution of cardiopulmonary bypass. Not only preoperatively it also necessitates appropriate neuromonitoring and neuroprotection during and after surgery. The association of unforeseen rupture of common carotid artery pseudoaneurysm secondary to the tubercular spine and lifesaving management by the rapid institution of cardiopulmonary bypass (CPB) is a rare occasion. To the best of the authors' knowledge, there is not any similar case in the peer-reviewed literature. Therefore, the authors enumerate the clinical experience of an unexpected rupture of CCA pseudoaneurysm requiring lifesaving CPB and emphasize the \"Timely Teamed Effort Approach\" that can sustain a life in such an inevitable situation.

Background: Cancellation of any scheduled surgery is a significant drain on health resources and potentially stressful for patients. It is frequent in menstruating women who are scheduled to undergo open heart surgery (OHS), based on the widespread belief that it increases surgical and menstrual blood loss. Aims: The aim of this study was to evaluate blood loss in women undergoing OHS during menstruation. Settings and Design: A prospective, matched case-control study which included sixty women of reproductive age group undergoing OHS. Patients and Methods: The surgical blood loss was compared between women who were menstruating (group-M; n = 25) and their matched controls, i.e., women who were not menstruating (group-NM; n = 25) at the time of OHS. Of the women in group M, the menstrual blood loss during preoperative (subgroup-P) and perioperative period (subgroup-PO) was compared to determine the effect of OHS on menstrual blood loss. Results: The surgical blood loss was comparable among women in both groups irrespective of ongoing menstruation (gr-M = 245.6 ± 120.1 ml vs gr-NM = 243.6 ± 129.9 ml, P value = 0.83). The menstrual blood loss was comparable between preoperative and perioperative period in terms of total menstrual blood loss (gr-P = 36.8 ± 4.8 ml vs gr-PO = 37.7 ± 5.0 ml, P value = 0.08) and duration of menstruation (gr-P = 4.2 ± 0.6 days vs gr-PO = 4.4 ± 0.6 days, P value = 0.10). Conclusion: Neither the surgical blood loss nor the menstrual blood loss is increased in women undergoing OHS during menstruation.
