Could Selective Re-look Angiography Improve the Outcome of Cardiogenic Shock in Patients Under Veno-arterial Extracorporeal Membrane Oxygenator?

It is not well studied whether a secondary look by angiography (Re-Ang) after fixing the culprit lesion would be beneficial or not in cardiogenic shock (CS) supported by veno-arterial extracorporeal membrane oxygenator (VA-ECMO). This study was a retrospective observational one that looked at 5-year data from a single tertiary center. Patients were grouped according to the need of Re-Ang during the VA-ECMO course into 2 groups.

Chest radiography requirements for patients with asymptomatic COVID-19 undergoing coronary artery bypass surgery: Three case reports.

Background: The coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2, represents a major challenge to health care systems both globally and regionally, with many opting by cancelling elective surgeries. Cardiac operations in patients diagnosed with COVID-19 have been imperative due to their emergency nature, critical condition of patients awaiting cardiac surgery, and accumulated number of cardiac surgical interventions throughout the last months.

Case Summary: Here we describe three COVID-19 positive cases who underwent coronary surgery, on an urgent basis.

Urgent coronary artery bypass graft surgery supported by veno-arterial extracorporeal membrane oxygenation: a report of two cases.

Mechanical circulatory support (MCS) devices, especially veno-arterial extracorporeal membrane oxygenation (VA-ECMO) devices, are increasingly used to shore complex cardiac procedures in high-risk patients. We are reporting two cases where patients underwent coronary artery bypass grafting (CABG) under support of VA-ECMO in the setting of cardiogenic shock complicating acute myocardial infarction. The patients had different courses, but both survived the initial insult and were weaned successively from VA-ECMO.

Periprocedural Anticoagulation Management of Patients receiving Warfarin in Qatar: A Prospective Cohort Study.

Background: The use of anticoagulant bridging remains controversial. This study was conducted to evaluate our warfarin periprocedural management in Qatar and investigate the associated clinical outcomes with such management.

Methods: A prospective cohort study was designed to describe the periprocedural clinical practice in warfarin patients in Qatar and to compare clinical safety and efficacy outcomes between anticoagulant bridging and nonbridging.

SARS-CoV-2 (COVID-19) PCR cycle threshold: can it help in the timing of urgent cardiac surgery?

Background: The COVID-19 pandemic has resulted in a significant reduction in urgent cardiac surgery due to concerns about safety for both patients and care givers. The timing of safe cardiac surgery is yet to be clarified in the setting of COVID-19 diagnosis.

Methods: Due to the urgency of the cardiac conditions on presentation, we have operated on four patients who exhibited the spectrum of COVID-19 disease from asymptomatic to severe COVID-19 pneumonia.

A tale of three pumps and a mechanical heart.

Temporary mechanical circulatory support device (tMCS) failure could qualify patients with advanced heart failure to receive a long-term solution. We report on a patient who presented with cardiorespiratory arrest that required a tMCS and developed acute type A aortic dissection. Data Sources: our case adds further evidence regarding the support of a patient with a second (or more) incidence of tMCS.

Perioperative management of COVID 19 patients undergoing coronary artery bypass surgery.

• COVID-19 represents a major challenge for healthcare systems globally and regionally. • The complexity of the disease requires special considerations when cardiac surgery is imminent. • Worsening of the patients’ clinical condition because of COVID-19 association was not encountered in our series.

"High Frequency/Small Tidal Volume Differential Lung Ventilation": A Technique of Ventilating the Nondependent Lung of One Lung Ventilation for Robotically Assisted Thoracic Surgery.

With the introduction of new techniques and advances in the thoracic surgery fields, challenges to the anesthesia techniques had became increasingly exponential. One of the great improvements that took place in the thoracic surgical field was the use of the robotically assisted thoracic surgical procedure and minimally invasive endoscopic thoracic surgery. One lung ventilation technique represents the core anesthetic management for the success of those surgical procedures.
