Background: Takotsubo cardiomyopathy (TTC) is a non-ischaemic cardiomyopathy, characterized by transient wall motion abnormalities of the left ventricle. Although biventricular involvements are common with a poor prognosis, isolated right ventricular (RV) involvement of TTC is a rare, and its diagnosis remains challenging.
Case Presentation: We encountered a case of isolated RV-TTC presenting as acute RV failure, with progression to cardiogenic shock requiring intensive treatment. Conflicting echocardiographic findings of RV asynergy with RV enlargement despite normal left ventricular wall motion and mild tricuspid regurgitation led to the correct diagnosis. Finally, the patient showed complete recovery with normalization of cardiac structure and function.
Conclusions: This case underscores the clinical significance of considering isolated RV-TTC as a new distinct variant form of TTC in terms of presentation, diagnostic findings, differential diagnosis, treatment strategy, and prognosis.

To investigate how PD-L1 monoclonal antibodies (mAbs) affect the left ventricular function in mice with myocardial infarction (MI) and through what mechanisms they exert their effects. In vivo experiments were conducted using 27 female BALB/c mice, which were divided equally into 3 groups. Cardiac function was assessed by ultrasound.

Purpose: Despite significant improvements in the design and performance of continuous flow left ventricular assist devices (CFLVADs), one of the most important reasons hampering further penetration of this technology is the occurrence of adverse events, especially strokes. One of the well-known risk factors for strokes is hypertension which is particularly common in patients undergoing a CFLVAD implant. While the device is implanted in the heart, strokes happen due to pathology in the brain and we hypothesised that modelling the blood flow in the circle of Willis might shed light on the causation of strokes in this situation.

Cardiac cystic echinococcosis is a rare form of cystic hydatid disease. Hydatid cysts are multilocular and are picked up incidentally. We here describe a case of an isolated unilocular cardiac hydatid cyst of the interventricular septum with multimodality imaging, treatment approach, and operative findings.

Sustained pathologic myocardial hypertrophy can result in heart failure(HF); a significant health issue affecting a large section of the population worldwide. In HF there is a marked elevation in circulating levels of the peptide urotensin II(UII) but it is unclear whether this is a result of hypertrophy or whether the high levels contribute to the development of hypertrophy. The aim of this study is to investigate a role of UII and its receptor UT in the development of cardiac hypertrophy and the signalling molecules involved.

Objectives: We present a case series of patients with granulomatous myocarditis presenting as atrial arrhythmias accompanied by lymphadenopathy.
Background: Atrial myocarditis (AM) may be the cause of atrial fibrillation (AF) in patients without risk factors.
Methods: Patients with atrial fibrillation without risk factors underwent 18F-Fluorodeoxyglucose positron emission tomography (18F-FDG-PET).
