What If We Let It Fibrillate? New Perspective on Atrial Fibrillation in Sepsis.
(PubMed, Curr Med Sci)
- "Studies with ultrashort-acting beta-blockers, such as esmolol and landiolol, have shown that hemodynamic stabilization may occur even in the absence of sinus rhythm restoration. Recognizing AF as a potential adaptive rhythm reframes research priorities: identifying biomarkers of atrial inflammation, stratifying patients according to hemodynamic impact, and testing permissive versus corrective strategies in prospective trials. The permissive AF strategy proposed herein is expected to foster patient-centered care and reduce iatrogenic harm in the complex interplay between sepsis and the heart."

Permanent Junctional Reciprocating Tachycardia (PJRT): A Rare Case of Refractory Neonatal SVT
(SCCM 2026)
- "There, he underwent six attempts of transcutaneous pacing and was started on a combination of esmolol, flecainide, and amiodarone. However, in neonates this procedure is very rarely performed. Given its resistance to pharmacologic agents, PJRT demands early recognition and a targeted approach to management in pediatric and neonatal populations."

Utilization of Intravenous Immunoglobulin for Basedow Paraplegia in Thyroid Storm
(SCCM 2026)
- "After 12 days of management with cholestyramine, dexamethasone, esmolol, and methimazole, thyroid hormone levels normalized, and sedation was stopped. Given the theorized immune-mediated aspect of BP, IVIG, a therapy utilized for immune-mediated myopathies, was trialed. In this case of thyrotoxic myopathy, normalization of thyroid hormone levels failed to resolve the paralysis, and muscle strength improved after a 5-day course of IVIG."

Severe Pediatric Caffeine Toxicity: Early Extracorporeal Therapy With TPE and CRRT
(SCCM 2026)
- "She was intubated and treated with anticonvulsants, epinephrine infusion, and propofol for transport. In the PICU, a 240 bpm wide-complex tachycardia was treated with a 100 mg lidocaine load, three synchronized cardioversions, and titration of an esmolol infusion for rate control.The initial caffeine level was 241 mcg/mL (therapeutic range 5-20 mcg/mL)...Its low molecular weight, minimal protein binding, and small volume of distribution favor clearance with dialysis. This case highlights that combined TPE and CRRT may rapidly reduce toxic levels and manage rhabdomyolysis, supporting early extracorporeal therapy in severe pediatric caffeine poisoning."

Characterization of Esmolol Use for Acute Aortic Syndrome at a Tertiary Academic Medical Center
(SCCM 2026)
- "Esmolol was not effective in achieving an initial heart rate goal in 64% of patients. Despite the relaxation of heart rate goals in 67% of the study population, 37% still never reached their target heart rate. Patients not meeting their initial heart rate goal required higher esmolol doses and received larger volumes from the infusion."

Esmolol Versus Labetalol in Acute Aortic Syndromes
(SCCM 2026)
- "In this retrospective crossover analysis of AAS, there was a higher proportion of esmolol infusions that failed to achieve hemodynamic goals compared to labetalol, but no statistically significant differences were observed. Labetalol was associated with a lower rate of secondary vasoactive agent use, fewer therapy changes, and reduced drug volume requirements compared to esmolol."

Rethinking Our PLEXit Strategy in Thyroid Storm: When to Cut Our Losses on Medical Therapy Alone
(SCCM 2026)
- "Medical therapy includes methimazole or propylthiouracil, beta blocker, iodine, glucocorticoids, and cholestyramine...Despite treatment for thyroid storm with methimazole, esmolol, potassium iodide, hydrocortisone, and cholestyramine, she continued to deteriorate with worsening shock requiring multiple vasopressors, liver and kidney failure, and was subsequently intubated...We argue that PLEX should be considered earlier in medically refractory cases, such as in our patient, whose acute liver failure likely disrupted thyroid metabolism. Prompt initiation of PLEX could be a life-saving measure, and this case illustrates the importance of considering this intervention earlier in medically refractory thyroid storm."

Dual Threat: Hemodynamic Challenges in Stroke With Acute Type A Aortic Dissection
(SCCM 2026)
- "Esmolol and nicardipine infusions were started with goals of systolic BP < 120 mmHg and HR < 60 bpm...Postoperatively, BP was maintained around 140 mmHg with HR < 100 bpm using norepinephrine, nitroglycerin, and nicardipine infusions...Prioritizing aortic protection may risk cerebral hypoperfusion, while maintaining cerebral perfusion may exacerbate aortic wall injury. This case emphasizes the importance of tailored decision-making to navigate conflicting therapeutic goals and reduce morbidity in critically ill patients."

RAGING HEART, CALM THYROID: REFRACTORY AF CONTROLLED WITH IV AMIODARONE WITHOUT WORSENING HYPERTHYROIDISM
(ACC 2026)
- "Electrocardiogram showed sinus tachycardia.Shortly after admission, the patient developed atrial fibrillation (AF) with rapid ventricular response (RVR) which was refractory to multiple doses of IV metoprolol, IV diltiazem, and two rounds of synchronized cardioversion. He was subsequently started on IV esmolol drip and digoxin.Further workup revealed suppressed TSH (<0.01 mIU/L) with elevated free T4 (2.82 ng/dL) and T3 (53.17 ng/dL)...He also received hydrocortisone, methimazole, IV fluids, and antibiotics, leading to hemodynamic stabilization... IV amiodarone can be considered in thyroid storm with refractory tachyarrhythmias. Potential mechanisms may include induction of the Wolff-Chaikoff effect and inhibition of peripheral T4 to T3 conversion. Short term IV use has been reported to stabilize both arrhythmias and thyroid function, although robust clinical data are lacking."

WHEN THE THYROID STORMS THE HEART: A CHALLENGING CASE OF THYROTOXICOSIS-INDUCED CARDIOGENIC SHOCK REQUIRING VA-ECMO
(ACC 2026)
- "Of note, patient had not taken her methimazole and atenolol for several months...Patient was initiated on high dose steroids, esmolol, methimazole, potassium iodide, and lithium... Thyrotoxicosis-induced circulatory collapse portends a grim prognosis. It is critical to quickly diagnose and treat this condition, harnessing the power of a multidisciplinary team. Prompt initiation of VA-ECMO often becomes necessary to offer a positive outcome, although sadly in our patient's case, it was still not enough."

Systolic-Synchronized Intraventricular Pump with an Embedded Bio-Impedance Sensor Adjusting Pump Parameters to LV Unloading and Impairment Levels
(ISHLT 2026)
- "To facilitate this personalized approach, a bio-impedance sensor was embedded into the FM allowing for the continuous monitoring of hemodynamic and anatomical parameters.Methods Acute implantation of a FM was conducted in a healthy calf with esmolol-induced contractility and altered cardiac output to assess the hemodynamic performance of the pump...In a HF patient, the additional SV value should be higher, as the heart's baseline ejection velocity is lower 0.6-0.8 m/s, whereas in a healthy calf, the ejection velocity was near the pump outlet velocity 1 m/s. The current work will provide valuable information to clinicians to optimize the FM therapy and achieve myocardial recovery."
