76-year-old female presented following an episode of collapse. She was hypotensive with the paramedics and remained refractory despite fluid resuscitation. Her initial baseline tests revealed an elevated troponin; she subsequently underwent a coronary angiogram that showed mild coronary artery disease. Left ventriculogram was performed, which showed abnormal mid-wall ballooning and severely impaired systolic function, characteristic of Takotsubo syndrome. Echocardiogram confirmed the presence of diagnosis and presence of left ventricular outflow tract obstruction with high gradient. She was initiated on medical heart failure therapy and improved. Follow-up investigations after 2 months showed complete resolution of systolic dysfunction and symptoms., Learning Points: Takotsubo syndrome can present similarly to ACS.Early use of echocardiography in the acute setting can provide vital information.Takotsubo syndrome can result in hemodynamic instability requiring urgent interventions.Other investigative modalities can be used in conjunction with echocardiography to confirm the diagnosis of Takotsubo syndrome.Prognosis is generally good in patients with Takotsubo syndrome., (© 2017 The authors.)

A 25-year-old male with a background of ulcerative colitis presented with a two-week history of central chest pain. His ECG on presentation showed global T wave inversion with a peak troponin I of 165 ng/ml. Clinical diagnosis of myopericarditis/myocarditis was made. Echocardiography and cardiac MR confirmed the diagnosis. On detailed assessment of his medication history, mesalazine was suspected as an aetiological factor, with discontinuation resulting in an improvement in symptoms, inflammatory markers and cardiac enzymes. This is a unique case of mesalazine induced myopericarditis on a background of inflammatory bowel disease., (© 2017 The authors.)

A 73-year-old male was brought into hospital with chest pain and inferior ST elevation on ECG. The patient immediately proceeded to the catheter lab for primary percutaneous coronary intervention. Angiography did not identify any culprit lesions to account for the patient's electrocardiographic changes and ongoing symptoms of chest pain. Bedside echocardiography revealed critical aortic stenosis. Intra-aortic balloon pump (IABP) was inserted, resulting in resolution of chest pain and ST-segment changes. The patient underwent successful aortic valve (AV) replacement without the need for coronary intervention. This is a rare presentation of critical aortic stenosis (AS) presenting as ST-segment elevation myocardial infarction (STEMI)., Learning Points: Aortic stenosis (AS) affects 2-9% of population above 65 years old and increases with age.AS induces ischaemia via abnormal cardiac coronary coupling.Focused clinical examination in patients with ST-segment elevation myocardial infarction (STEMI) is vital prior to cardiac catheterisation.Detection of murmurs should be followed on by an echocardiography examination.Other differentials of STEMI include acute aortopathy, endocarditis with embolus, myopericarditis and intracranial haemorrhage., (© 2017 The authors.)
