A 60-year-old man with squamous cell carcinoma of the tongue had atypical chest pain and mild troponin elevation. No significant electrocardiogram changes or arrhythmias were noted. Cardiac magnetic resonance revealed several myocardial metastases with pericardial involvement, confirmed by positron emission tomography/computed tomography. Unsuitable for surgery, he was referred for palliative chemotherapy., Competing Interests: The authors have reported that they have no relationships relevant to the contents of this paper to disclose., (© 2025 The Authors.)

It is important to maintain a vigilant approach towards incidental, rare findings like coronary artery aneurysms (CAAs) presenting with arrhythmia, particularly in patients with a history of myocardial infarction and cardiovascular risk factors. Diagnosis needs thorough evaluation. Tailoring management strategies to individual patient characteristics is crucial for optimizing outcomes., Competing Interests: The authors declare that they have no competing interests., (© 2024 The Author(s).

Background: Transcatheter patent foramen ovale (PFO) occluder device is a procedure mostly performed to prevent secondary stroke as a result of paradoxical emboli traversing an intracardiac defect into the systemic circulation. The complications and outcomes following the procedure remain poorly studied. We aimed to investigate morbidity and mortality associated with occluder device procedures using hospital frailty index score stratification., Methods: The Nationwide Readmission Database was employed to identify patients admitted for PFO closure from 2016 to 2020. Two groups divided by index frailty score were compared to report adjusted odds ratio (aOR) for primary and secondary cardiovascular outcomes. Outcomes included in-hospital mortality, acute kidney injury, acute ischemic stroke, and post-procedure bleeding. Statistical analysis was performed using STATA v.17 ., Results: Of the 2,063 total patients who underwent the procedure, 45% possessed intermediate to high frailty scores while the other 55% had low frailty scores. The first cohort had higher odds of in-hospital mortality (aOR 6.3, 95% CI 2.05-19.5), acute kidney injury (aOR 17.6, 95% CI 9.5-32.5), and stroke (aOR 3.05, 95% CI 1.5-5.8) than the second cohort. There was no difference in the incidence of post-procedural bleeding and cardiac tamponade and 30/90/180-day readmission rates between the two cohorts. Hospitalizations in the first cohort were associated with a higher median length of stay and total cost., Conclusion: High to intermediate frailty scores may predict an increased risk of in-hospital mortality in patients undergoing PFO occluder device procedures., Competing Interests: None., (AJCD Copyright © 2024.)

Pulmonary embolism (PE) is a common acute cardiovascular condition. Within this review, we discuss the incidence, pathophysiology, and treatment options for patients with high-risk and massive pulmonary embolisms. In particular, we focus on the role of mechanical circulatory support devices and their possible therapeutic benefits in patients who are unresponsive to standard therapeutic options. Moreover, attention is given to device selection criteria, weaning protocols, and complication mitigation strategies. Finally, we underscore the necessity for more comprehensive studies to corroborate the benefits and safety of MCS devices in PE management.

Serotonin toxicity, an adverse consequence of elevated serotonin levels in the brain, poses a considerable threat to life. Antidepressants, frequently prescribed for various conditions in older adults, such as depression, anxiety, and sleep disturbances, significantly contribute to this risk. The elderly are particularly vulnerable due to multiple comorbidities, cognitive decline, medication interactions, polypharmacy, and chronic kidney disease. This case underscores the critical importance of considering serotonin syndrome as a potential diagnosis in patients using serotonin and norepinephrine reuptake inhibitors, especially within vulnerable populations. Here, we present the case of an 89-year-old female who presented with altered mental status and a hypertensive emergency. Following a thorough examination and exclusion of alternative causes of acute encephalopathy, serotonin syndrome induced by the use of venlafaxine and oxycodone was diagnosed., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Erdem et al.)

Patent foramen ovale (PFO) occluder devices are increasingly utilized in minimally invasive procedures used to treat cryptogenic stroke. Data on the impact of Atrial Fibrillation (AF) among PFO occluder device recipients are limited. The Nationwide Readmissions Database was queried between 2016 and 2019 to identify PFO patients with and without AF. The 2 groups were compared using propensity score matching (PSM) and multivariate regression models. The outcomes included in-hospital mortality, acute kidney injury (AKI), Mechanical circulatory support use (MCS), Cardiogenic shock (CS), acute ischemic stroke, bleeding, and other cardiovascular outcomes. Statistical analysis was performed using STATA v. 17. Out of 6508 Weighted hospitalizations for PFO occluder device procedure over the study period, 877 (13.4%) had AF compared to 5631 (86.6%) who did not. On adjusted analysis, PFO with AF group had higher rates of MCS (PSM, 4.5% vs 2.2 %, P value = 0.011) and SCA (PSM, 7.6% vs 4.6 %, P value = 0.015) compared to PFO with no AF. There was no statistically significant difference in the rate of in-hospital mortality (PSM, 5.4% vs 6.4 %, P value = 0.39), CS (PSM, 8.3% vs 5.9 %, P value = 0.075), AKI (PSM, 32.4% vs 32.3 %, P value = 0.96), bleeding (PSM, 2.08% vs 1.3%, P value = 0.235) or the readmission rates among both cohorts. Additionally, AF was associated with higher hospital length of stay (9.5 ± 13.2 vs 8.2 ± 24.3 days, P-value = 0.012) and total cost ($66,513 ± $80,922 vs $52,013±$125,136, 0.025, P-value = 0.025) compared to PFO without AF. AF among PFO occluder device recipients is associated with increased adverse outcomes, including MCS use and SCA, with no difference in mortality and readmission rates among both cohorts. Long-term follow-up needs further studies., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Transcatheter aortic valve implantation (TAVI) is accepted as an alternative to surgery, but data on combined percutaneous coronary interventions (PCI) and TAVI during the same in-hospital stay are still lacking. Using the national inpatient sample (NIS) database, we identified all TAVI encounters and compared in-hospital outcomes of patients who had TAVI only to patients who had TAVI and PCI. We used multivariable logistic regression analysis to calculate the adjusted odds ratio (aOR). Of 291,810 patient encounters with TAVI, 13,114 (4.5%) had combined PCI during the same index admission. The average age was 79.61 ± 8.61 years in the TAVI-only vs 80.25 ± 8.73 years in the combined TAVI-PCI group. Combined TAVI and PCI was associated with higher in-hospital mortality (4.5% vs 1.8%, aOR: 2.3), stroke (4.7% vs 2.9%, aOR: 1.4), net adverse events (NAE) (20.2% vs 5.7%, aOR: 3.6), major bleeding (40.1% vs 24.3%, aOR: 1.8), vascular complications (10.6% vs 2.5%, aOR: 3.9), acute kidney injury (AKI) (23.3% vs 11.7%, aOR: 2.1), hemodialysis (HD) (4.2% vs 2.4%, aOR: 1.4), postoperative cardiogenic shock (1.2% vs 0.4%, aOR: 2.8), need for mechanical circulatory support (6.9% vs 1%, aOR: 7); p-value < 0.001 for all. The utilization of permanent pacemakers was similar between the groups (9.8% vs 9.2%, aOR: 1; p = 0.6). Combining TAVI and PCI during the same index admission is associated with worse outcomes. The decision to do PCI for patients undergoing TAVI should be individualized and tailored based on the patient's clinical conditions., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Extracorporeal membrane oxygenation (ECMO) is a significant treatment modality for COVID-19 patients on ventilators. The current data is limited for understanding the indicators and outcomes of ECMO in COVID-19 patients with acute respiratory distress syndrome (ARDS). The National Inpatient Sample (NIS) database from 2020 was queried in this study. Among 1,666,960 patients admitted with COVID-19, 99,785 (5.98%) patients developed ARDS, and 60,114 (60.2%) were placed on mechanical ventilation. Of these mechanically ventilated COVID-ARDS patients, 2580 (4.3%) were placed on ECMO. Patients with ECMO intervention had higher adjusted odds (aOR) of blood loss anemia (aOR 9.1, 95% CI: 6.16-13.5, propensity score-matched (PSM) 42% vs 5.4%, P < 0.001), major bleeding (aOR 3.79, 95% CI: 2.5-5.6, PSM 19.9% vs 5.9%, P < 0.001) and acute liver injury (aOR 1.7, 95% CI: 1.14-2.6 PSM 14% vs 6%, P = 0.009) compared to patients without ECMO intervention. However, in-hospital mortality, acute kidney injury, transfusions, acute MI, and cardiac arrest were insignificant. On subgroup analysis, patients placed on veno-arterial ECMO had higher odds of cardiogenic shock (aOR 13.4, CI 3.95-46, P < 0.0001), cardiac arrest (aOR 3.5, CI 1.45-8.47, P = 0.0057), acute congestive heart failure (aOR 4.18, CI 1.05-16.5, P = 0.042) and lower odds of major bleeding (aOR 0.26, CI 0.07-0.92). However, there was no significant difference in mortality, intracranial hemorrhage, and acute MI. Further studies are needed before considering COVID-19 ARDS patients for placement on ECMO., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Pneumatosis intestinalis (PI) is a relatively rare gastrointestinal finding that has a wide variety of causes - ranging from benign to life-threatening. It is described as the pathological presence of gas within the bowel wall with multiple hypotheses emerging as to the likely mechanism. An important indicator of a life-threatening source of PI is the presence of gas within the hepatic portal vein, referred to as hepatic portal venous gas (HPVG). While non-specific for isolated PI, HPVG has been reported in PI patients to be associated with bowel ischemia and is thereby considered an indication for emergent management. Herein we report a case involving an atypical presentation of altered mental status in which the patient was found to have PI with contemporaneous HPVG. These findings have been reported to have a high mortality rate. Our patient rapidly deteriorated during their hospital course, expiring shortly after being deemed a poor surgical candidate due to their severe co-morbidity burden. Through this case, we review evidence supporting the management of patients with PI and concurrent HPVG from an extensive review of available literature. While PI is a non-specific finding and commonly a source of diagnostic confusion, a better understanding of its natural course and potentially unorthodox sequela may afford more directed and crucial care for critically ill patients, in which time is often a precious commodity., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Erdem et al.)

Transradial access (TRA) and transulnar access (TUA) are in close vicinity, but TRA is the preferred intervention route. The cardiovascular outcomes and access site complications of TUA and TRA are understudied. Databases, including MEDLINE and Cochrane Central registry, were queried to find studies comparing safety outcomes of both procedures. The outcome of interest was in-hospital mortality and access site bleeding. Secondary outcomes were all-cause major adverse cardiovascular events, crossover rate, artery spasm, access site large hematoma, and access site complications between TUA and TRA. A random-effect model was used with regression to report unadjusted odds ratios (ORs) by limiting confounders and effect modifiers, using software STATA V.17. A total of 4,796 patients in 8 studies were included in our analysis (TUA = 2,420 [50.4%] and TRA = 2,376 [49.6%]). The average age was 61.3 and 60.1 years and the patients predominantly male (69.2% vs 68.4%) for TUA and TRA, respectively. TUA had lower rates of local access site bleeding (OR 0.58, 95% confidence interval 0.34 to 0.97, I 2  = 1.89%, p = 0.04) but higher crossover rate (OR 1.80, 95% confidence interval 1.04 to 3.11, I 2  = 75.37%, p = 0.04) than did TRA. There was no difference in in-hospital mortality, all-cause major adverse cardiovascular events, arterial spasm, and large hematoma between both cohorts. Furthermore, there was no difference in procedural time, fluoroscopy time, and contrast volume used between TUA and TRA. TUA is a safer approach, associated with lower access site bleeding but higher crossover rates, than TRA. Further prospective studies are needed to evaluate the safety and long-term outcomes of both procedures., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier Inc.

We describe a rare case of a  Streptococcus pneumoniae  ( S. pneumoniae ) infection causing mitral valve endocarditis and bacterial meningitis in a previously healthy young adult male in his 20s who presented with altered mentation. Though our patient did not endorse any respiratory issues, we suspected the paranasal sinuses to have been the cryptic primary source of disseminated infection into the respiratory system and meninges due to incidental mucosal thickening being found on imaging. Blood and cerebrospinal fluid analyses and cultures revealed the proliferation of  S. pneumoniae  serotype 23B, despite our patient having previously received appropriate pneumococcal vaccinations in his childhood without delinquency. Ultimately, surgical replacement of the mitral valve, as well as a course of ceftriaxone, was indicated for this patient, in which full resolution of symptoms was achieved upon discharge., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Erdem et al.)

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) cannulation is a potential cause of episodic bradycardia during an intensive care course because of the proximal cannula insertion site being in the vicinity of the carotid sinus. Herein, we report the case of episodic bradycardia throughout a multi-week intensive care stay of a VV-ECMO recipient due to a severe coronavirus disease 2019 (COVID-19) infection that did not emerge for the rest of the patient's hospitalization after decannulation., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Dayco et al.)

Cardiorenal benefits of sodium-glucose cotransporter 2 inhibitors (SGLT2is) have been demonstrated in patients with type 2 diabetes in multiple trials. We aim to provide a comprehensive review of the role of SGLT2i in cardiovascular disease. Reducing blood glucose to provide more effective vascular function, lowering the circulating volume, reducing cardiac stress, and preventing pathological cardiac re-modeling and function are the mechanisms implicated in the beneficial cardiovascular effects of SGLT2 inhibitors. Treatment with SGLT2i was associated with a decrease in cardiovascular and all-cause mortality, acute heart failure exacerbation hospitalization, and composite adverse renal outcomes. Improved symptoms, better functional status, and quality of life were also seen in heart failure with reduced ejection fraction (HFrEF), heart failure and mildly reduced ejection fraction (HFmrEF), and heart failure with preserved ejection fraction (HFpEF) patients. Recent trials have shown a notable therapeutic benefit of SGLT2is in acute heart failure and also suggest that SGLT2is have the potential to strengthen recovery after acute myocardial infarction (AMI) in percutaneous coronary Intervention (PCI) patients. The mechanism behind the cardio-metabolic and renal-protective effects of SGLT2i is multifactorial. Adverse events may occur with their usage including increased risk of genital infections, diabetic ketoacidosis, and perhaps limited amputations; however, all of them are preventable. Overall, SGLT2i clearly has many beneficial effects, and the benefits of using SGLT2i by far outweigh the risks., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Erdem et al.)

A patient with severe aortic stenosis and left ventricular hypertrophy underwent a transcatheter aortic valve replacement. The patient's blood pressure significantly dropped after protamine administration. A diagnosis of suicide left ventricle post-valve replacement was made. The diagnosis and management of the protamine reaction are detailed. This case highlights the need to slowly infuse protamine sulfate and monitor for adverse events., (© 2023 Wiley Periodicals LLC.)
