ABSTRACT

Kounis syndrome (KS) is an acute coronary syndrome triggered by allergic or anaphylactic reactions. It manifests as coronary artery vasospasm, acute myocardial infarction, or coronary stent thrombosis, resulting from inflammatory cytokine release and inappropriate activation of platelets and mast cells. We present a case of an 85-year-old male with Crohn's disease who suffered anaphylaxis during infliximab infusion, culminating in non-ST myocardial infarction (NSTEMI). The patient's symptoms were effectively managed with epinephrine and diphenhydramine, and KS secondary to infliximab was diagnosed. Diagnosing KS can be challenging due to the overlapping signs of an allergic reaction and myocardial infarction. Timely recognition and appropriate management of KS are crucial to enhance patient outcomes. Therefore, healthcare providers should maintain a high index of suspicion for KS in patients with acute coronary syndromes linked to allergic reactions to optimize care and minimize potential risks. This case report underscores the significance of prompt intervention and awareness of Kounis syndrome in clinical practice.

ABSTRACT

This case report describes a rare variant of partial anomalous pulmonary venous connections (PAPVCs) in a patient who presented with an insidious progression of dyspnea on exertion as an adult, leading to the diagnosis of PAPVC. The patient had an anomalous right upper pulmonary vein connecting to an anomalous pulmonary-azygos trunk that connected to the cranial superior vena cava (SVC), producing a large left-to-right extracardiac shunt. The diagnosis of PAPVC was made after evaluating for causes of right heart chamber enlargement. This case highlights the importance of considering PAPVC as a potential cause of unclear etiology for exertional dyspnea, right-sided chamber enlargements, and intact atrial septum. The onset and severity of symptoms in patients with PAPVC depend on various factors, including the number of pulmonary veins, site of connection, pulmonary vascular resistance, atrial compliance, and the presence of other congenital heart defects. Therefore, clinicians should maintain a high level of suspicion for PAPVC in patients with these types of symptoms.

ABSTRACT

Arterial pseudoaneurysm formation after transradial cardiac catheterization is a rare post-procedural complication occurring in less than 0.1% of radial arterial access. While the data on the management of femoral pseudoaneurysms is extensive, few studies have evaluated how these techniques apply for small vessel arterial pseudoaneurysms. We present the case of an octogenarian man with a radial artery pseudoaneurysm after transradial coronary intervention that failed initial compression therapy, and surgical intervention was avoided by applying continuous compression therapy with a TR Band® radial compression device.
