Cardiac surgery during the COVID-19 sine wave: Preparation once, preparation twice. A view from Houston.

The novel coronavirus disease (COVID-19) pandemic has created major challenges and disruptions to hospitals throughout the world, with profound implications for cardiac surgery and cardiac surgeons. In this review, we highlight the hospital and cardiac surgical experience at Baylor St. Luke's Medical Center in the Texas Medical Center in Houston, Texas as of mid-July 2020.

Anesthetic Management of Laser Lead Extraction for Cardiovascular Implantable Electronic Devices.

Cardiovascular implantable electronic devices (CIEDs) play a significant role in the modern management of cardiovascular disease. CIEDs include implantable pacemakers (PMs), implantable cardioverter-defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices. These devices improve the quality of life of their recipients and help reduce the incidence of sudden cardiac death.

Anesthetic Management of Patients Undergoing Percutaneous Endocardial and Epicardial Left Atrial Appendage Occlusion.

Atrial fibrillation is the most common cardiac arrhythmia in adults affecting almost 6 million adults in the United States. The 2 most common comorbidities associated with atrial fibrillation are heart failure and thromboembolic events. Heart failure symptoms may be treated with rate control, antiarrhythmic medications or by catheter ablation.

Anesthetic Management in Radiofrequency Catheter Ablation of Ventricular Tachycardia.

Radiofrequency catheter ablation is increasingly being used to treat patients who have ventricular tachycardia, and anesthesiologists frequently manage their perioperative care. This narrative review is intended to familiarize anesthesiologists with preprocedural, intraprocedural, and postprocedural implications of this ablation. Ventricular tachycardia typically arises from structural heart disease, most often from scar tissue after myocardial infarction.

Early detection of a cavopulmonary tumor embolus with the use of transesophageal echocardiography.

Pulmonary tumor embolization from renal cell carcinoma is associated with severe cardiopulmonary morbidity and high perioperative mortality rates. We report the case of a 71-year-old woman who presented with right-sided abdominal pain. Magnetic resonance images revealed a mass originating from the upper pole of the right kidney and extending into the infrahepatic portion of the inferior vena cava.

Perioperative management of lower extremity revascularization.

Patients presenting for lower extremity revascularization often have multiple systemic comorbidities, making them high-risk surgical candidates. Neuraxial anesthesia and general anesthesia are equivocal in their effect on perioperative cardiac morbidity and improved graft patency. Postoperative epidural analgesia may improve perioperative cardiac morbidity.
