Takotsubo syndrome (TTS) is characterized by often reversible but acute heart failure occurring after an emotional or physical trigger event. The 'brain failure' counterpart is posterior reversible encephalopathy syndrome (PRES) characterized by often reversible but acute neurological symptoms. This case report elaborates on a complex clinical scenario with co-existence of coronary artery disease, TTS and PRES and discusses the pathophysiology, differential diagnosis, and management.

An 82-year-old woman presented with acute heart failure and generalized tonic-clonic seizures following an acute exacerbation of her chronic back pain. Brain magnetic resonance imaging demonstrated vasogenic oedema consistent with the diagnosis of PRES. Focal wall motion abnormalities on echocardiography without causal coronary stenoses on angiography were consistent with the diagnosis of TTS. After an interdisciplinary approach to differential diagnosis and treatment, the patient was discharged to geriatric rehabilitation without heart failure or neurological defects 4 weeks later.

TTS and PRES share significant similarities in proposed pathogenesis, epidemiology, management, and clinical outcome. This case report highlights the need for early recognition of this rare association and multidisciplinary approach to diagnosis and treatment as both heart and brain disease may require early intervention up to rapid intensive care support.

An endocardial radiofrequency ablation is a common approach for the treatment of idiopathic ventricular arrhythmia. find more However, rare cases have been reported in which ventricular arrhythmia could not be ablated from endocardium due to an epicardial origin of the arrhythmia.

In this article, we describe the rarely used, but acceptable approach to terminate ventricular arrhythmias in the summit of the left ventricle. We present a case of a 56-year-old patient with sustained monomorphic premature ventricular complexes, originating from the summit of the left ventricle, that were successfully eliminated. After unsuccessful ablation of the anterior wall right ventricular outflow tract, left coronary cusp, and distal coronary sinus, arrhythmia was eliminated by method of transvenous ethanol ablation. Complaints, such as palpitations and weakness, resolved after the procedure.

This approach is used when an epicardial location of the substrate of arrhythmia is suspected and ablation through the right ventricular outflow tract, left coronary cusp, and great cardiac vein fails. The total effectiveness of eliminating ventricular arrhythmia increases if it is possible to use endo- and epicardial methods of mapping and ablation. In clinics with extensive experience in this area, ethanol ablation of epicardial ventricular arrhythmia is safe and effective.

The Modified Duke criteria is an important structured schematic for the diagnosis of infective endocarditis (IE).
is a rare cause of IE that is often resistant to standard IE anti-microbials. We present a case of
IE, fulfilling the Modified Duke pathological criteria.

A 50-year-old male presented with left leg peripheral vascular disease with septic changes requiring amputation. Routine echocardiography post-amputation demonstrated severe aortic valve regurgitation with vegetations that required valve replacement. Two initial blood cultures from a single venepuncture showed
which was treated with penicillin G prior to surgery. Subsequent aortic valve tissue cultured
with suggestive IE histological valvular changes and was successfully treated on a prolonged course of vancomycin.

This is the first
IE case diagnosed on heart valvular tissue culture and highlights the importance for the fulfilment of the Modified Duke criteria in diagnosing left-sided IE. Mixed infection IE is rare, and this case possibly represents an unmasking of resistant
IE following initial treatment of penicillin G.
This is the first C. jeikeium IE case diagnosed on heart valvular tissue culture and highlights the importance for the fulfilment of the Modified Duke criteria in diagnosing left-sided IE. Mixed infection IE is rare, and this case possibly represents an unmasking of resistant C. jeikeium IE following initial treatment of penicillin G.
Discovering concomitant diagnoses results in a challenge to determine the true cause of a patient's presentation. Evaluating this fully is vital to plan appropriate and avoid inappropriate therapy.

A 55-year-old gentleman presents in cardiac arrest whilst watching an unusual occurrence of England dominating a Football World Cup game vs. Panama in 2018. Diagnostic coronary angiography discovered an anomalous right coronary artery from the opposite sinus (R-ACAOS), but clinical suspicion this was incidental lead to a further diagnosis of Type 1 Brugada Syndrome (BrS) following a positive Ajmaline provocation challenge. Risk stratification of these two zebras using computed tomography coronary angiography (CTCA), Cardiac magnetic resonance imaging (CMRI), Exercise Stress Echocardiography was performed and following a multi-disciplinary meeting, BrS was felt to be the primary diagnosis. The patient received a secondary prevention implantation of a cardiac defibrillator and avoided cardiac surgery.

Diagnosing a rare condition does not necessarily mean it is the cause of a patient's presentation and should not end the investigative process. Right coronary artery from the opposite sinus rarely causes cardiac arrest in middle age and is typically associated with peak exercise. Type 1 BrS is associated with cardiac arrest with vagal activity, perhaps such as England winning a World Cup game! Clinical correlation and risk stratification is required for suspected incidental findings.
