Case Studies

Total AV block as a cardiac manifestation of Weil’s disease

Weil’s disease is a zoonotic infection which may cause arrhythmias. This fatal case of total AV block induced by leptospirosis is a warning of the importance of early, and accurate, diagnosis and treatment of this infection. 

Diagnosing Bartonella-induced infective endocarditis

Blood culture-negative infective endocarditis can be difficult to diagnose. In this case, a woman with Bartonella-induced infective endocarditis required aortic valve replacement surgery, CABG, and targeted antibiotic therapy, 

Minimally invasive treatment of an LVA

Full median sternotomy is common in the surgical intervention of LVA, but can have negative long-term effects. In this case, LVA with concomitant VSR was successfully treated by minimally invasive bilateral thoracotomy.

Purulent pericarditis following oral fish bone impaction

The first reported case of E. corrodens and P. micra coinfection in a patient with purulent pericarditis, but does this unusual case have an even more unusual cause?

Rare complication of Kawasaki disease

Kawasaki disease rarely causes arrhythmias, but this infant was diagnosed with supraventricular tachycardia, which resolved after combination treatment with intravenous immunoglobulin and steroids.

Baffling chest pain in a healthy adolescent

Congenital agenesis of the pericardium, a rare and frequently asymptomatic anomaly, was diagnosed using cardiac imaging after a 16 year old presented with sudden onset, non-exertional chest pain. 

Pregnancy-related aortic dissection mistaken for anxiety

Dyspnea, chest pain and palpitations were initially attributed to an anxiety disorder in a pregnant woman. A chest CT revealed signs of chronic type A aortic dissection.

Multimodality imaging features of systemic amyloidosis

Myocardial amyloidosis is often missed in the early stages. Understand the importance of multimodal imaging in diagnosing systemic AL amyloidosis, particularly when patients present with extra-cardiac symptoms.

An idiopathic case of chylopericardium

A prime example of the the importance of multidisciplinary efforts in managing rare cases. Follow the diagnostic journey of this young man with idiopathic chylopericardium and chylothorax.

A culprit for the steal phenomenon

Can you explain the steal phenomenon? Read this example from a case of persistent angina lasting months after coronary artery bypass grafting, caused by a thick lateral costal artery. 

Cholesterol crystal embolization following alteplase for stroke

CCE led to multiorgan failure and death after intravenous alteplase to treat acute ischemic stroke. This case highlights the urgent need for greater awareness of this serious complication.

Myocarditis in a complex postpartum adolescent

An 18-year-old postpartum patient is admitted with concomitant acute myocarditis and congenital long QT syndrome with electrical storm and incessant Torsade de Pointes. What would your management strategy be?

Recurrent strokes after TAVR in patient with BAV

TAVR use has increased in low-risk patients, but serious complications can still occur. An elderly patient underwent TAVR to treat severe bicuspid aortic valve stenosis but experienced multiple strokes 6 months later.

A hypokalemic hypertension mystery

Reninoma should be considered in young people with hypokalemic hypertension when common causes have been excluded. Excision can cure hypertension and prevent morbidity and mortality.

Atypical Kawasaki disease in a 2-month-old boy

A case underscoring the importance of considering Kawasaki disease in infants presenting with prolonged, antibiotic-resistant fever, even though the condition is uncommon in children younger than 6 months.

DVT and aneurysm co-occurrence

An isolated rupture of the right common iliac aneurysm occurred in a young woman, one year after a deep vein thrombosis episode.

Acute MI presenting as headache

Acute myocardial infarction unusually presenting with primary complaint of headache and right arm numbness. After an ECG and enzyme analysis, cardiac cephalalgia was diagnosed and all symptoms resolved following revascularisation. 

Acute PDA stent occlusion in a newborn

Surgical resolution of a long tortuous patent ductus arteriosus from the undersurface of the aorta, in a newborn term infant diagnosed with Tetralogy of Fallot and pulmonary atresia.

Four cases of ICI-related fulminant myocarditis

Fatal outcomes in three cases, despite aggressive treatment, emphasize the poor prognosis of fulminant myocarditis related to immune checkpoint inhibitor therapy.

Use of GLP-1 agonists in patients with a Fontan circulation

A deep dive into eight cases of patients with a Fontan circulation who were prescribed GLP-1 agonists for obesity or diabetes. Find out if the treatments were effective, and what effects they had on patient comorbidities and safety outcomes.
