BACKGROUND: ProSeal laryngeal mask airways (PLMAs) are routinely used after failed tracheal intubation as airway rescue, facilitating tracheal intubation by acting as a conduit and to secure airway during emergencies. In long duration surgeries, use of endotracheal tube (ETT) is associated with various hemodynamic complications, which are minimally affected during PLMA use. However, except for few studies, there are no significant data available that promote the use of laryngeal mask during cardiac surgery...

Minimally invasive cardiac surgery is establishing itself as the standard of care across the world. MICS CABG is currently performed in only a few centers. Hemodynamics disturbances are peculiar during MICS CABG due to space constraints. We report a 70-year-old man who underwent MICS CABG who developed tension pneumothorax during revascularization that was diagnosed in a novel way.

The heart team, consisting of conservative cardiologists, cardiac surgeons and interventional cardiologists, is important for a balanced, multidisciplinary decision-making process for patients suffering from coronary artery disease (CAD). Standard evidence-based, interdisciplinary, institutional protocols can be used for commonly encountered case scenarios to avoid the need for a systematic case by case review. Complex cases with a SYNTAX score of more than 32, diabetes mellitus and lesions of the left main stem or three-vessel disease should in general not be treated by an ad hoc percutaneous coronary intervention (PCI) but first discussed in the heart team...

In patients with prior coronary artery bypass graft (CABG) surgery, distal coronary perforations are commonly considered to be at low risk for causing cardiac tamponade due to a potential protective role of pericardial adhesions, which obliterate the pericardial space. Loculated effusions can however form in such patients, compressing various cardiac structures and causing hemodynamic compromise. We present two cases of distal coronary perforation in prior CABG patients undergoing chronic total occlusion percutaneous coronary intervention...

UNLABELLED: A 61-year-old male presented to our emergency room with chest tightness, dyspnea, and cold sweat. He underwent a 12-lead EKG which showed ST-elevation from leads V1-V4 and T wave inversion in leads II, III, and aVF. His troponin-I level was elevated to 70.3 ng/ml. He went into cardiogenic shock when he was in the catheter room. After advanced cardiac life support was administered for 30 min, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) cannulation was set up using 21-french arterial and 21-french venous cannula through the right femoral artery and right femoral vein by the puncture method for hemodynamic support...

CONTEXT: Left ventricle diastolic dysfunction (LVDD) is gaining importance as useful marker of mortality and morbidity in cardiac surgical patients. Different algorithms have been proposed for the intraoperative grading of DD. Knowledge of the particular grade of DD has clinical implications with the potential to modify therapy, but there is a paucity of literature on the role of diastolic function evaluation during off-pump coronary artery bypass grafting (OPCABG) surgery. AIMS: The aim of this study was to monitor changes in LVDD using simplified algorithm proposed by Swaminathan et al...

The effects of isoflurane on the determinants of blood flow during Coronary Artery Bypass Graft (CABG) surgery are not completely understood. This study characterized the influence of isoflurane on the diastolic Pressure-Flow (P-F) relationship and Critical Occlusion Pressure (COP) during CABG surgery. Twenty patients undergoing CABG surgery were studied. Patients were assigned to an isoflurane or control group. Hemodynamic and flow measurements during CABG surgery were performed twice (15 minutes after the discontinuation of extracorporeal circulation (T15) and again 15 minutes later (T30))...

Background Neurohumoral and hemodynamic mechanisms have an effect on cardiac activity. C-type natriuretic peptide (CNP) is accessible in the cardiovascular system. The aim of this study was to determine whether CNP concentrations in pericardial fluid and blood are related to cardiac dysfunction in patients undergoing coronary artery bypass graft surgery. Materials and Methods In this study, 40 patients undergoing coronary artery bypass grafting were enrolled. The patients were separated into two groups according to left ventricular (LV) ejection fraction (EF): group 1 contained 28 patients with normal LV systolic function (LVEF ≥ 50%) and group 2 contained 12 patients with impaired LV systolic function (LVEF < 45%)...

BACKGROUND: Atrial fibrillation is the most common arrhythmia following cardiac surgery. It is associated with increased hemodynamic instability, systemic embolization, and complications linked to anticoagulant therapy. Oxidative stress and consequent electrophysiological remodeling have been proposed as a cause of postoperative atrial fibrillation. Ascorbic acid supplementation was suggested as a novel and effective preventive agent. The aim of this study was to evaluate the capability of ascorbic acid to reduce the incidence of postoperative atrial fibrillation in coronary artery bypass grafting (CABG) patients...

BACKGROUND: In observational studies of patients undergoing percutaneous coronary intervention (PCI), surgical ineligibility is associated with increased mortality. Whether the use of hemodynamic support during PCI can mitigate the adverse prognostic importance of surgical ineligibility is unknown. METHODS AND RESULTS: We sought to evaluate the association between request for surgical consultation (presumed surgical ineligibility) prior to PCI and clinical outcomes in 427 patients with multivessel coronary artery disease or unprotected left main disease and severely reduced left ventricular systolic function undergoing PCI assisted by hemodynamic support (intraaortic balloon pump or Impella) from the PROTECT II randomized trial...

BACKGROUND: Levosimendan a calcium ion sensitizer improves both systolic and diastolic functions. This novel lusitropic drug has predictable antiischemic properties which are mediated via the opening of mitochondrial adenosine triphosphate-sensitive potassium channels. This action of levosimendan is beneficial in cardiac surgical patients as it improves myocardial contractility, decreases systemic vascular resistance (SVR), and increases cardiac index (CI) and is thought to be cardioprotective...
