Background: A cardiac lipoma is a rare primary cardiac tumor. They are usually asymptomatic and carry a good prognosis. Cardiac Magnetic Resonance Imaging (CMR) is the confirmatory investigation of choice. Case presentation: We present a case of left ventricular lipoma in an asymptomatic patient, which was successfully treated with surgical resection. Conclusion: Cardiac lipomas are rare and are usually benign. There is no guideline on the management of cardiac lipomas and treatment is individualized.

Blunt thoracic trauma may result in cardiac injuries ranging from simple arrhythmias to fatal cardiac rupture. Coronary artery dissection culminating in acute myocardial infarction (AMI) is rare after blunt chest trauma. Here we report a case of a 37-year-old man who had an AMI secondary to coronary dissection resulting from blunt chest trauma after involvement in a physical fight.

The term myocardial infarction with non-obstructive coronary arteries (MINOCA) applies to patients who have clinical evidence of AMI but coronary angiography reveals no coronary obstructions and an alternative diagnosis is not possible. It is a heterogenous group of disease. Its prognosis, predictors of mortality and optimum management is unclear. In this review, we present a disease overview for MINOCA including the clinical features, adopted definitions, prevalence, diagnosis, treatment, and prognosis.

In the current issue of the Journal, Mogassabi et al. review the effects of waterpipe (WP) smoking on the respiratory system. [1] The article is a narrative, nonsystemic review on the acute and long-term effects of WP smoking on the respiratory system. Among the serious acute respiratory effects of WP smoking on the respiratory system that have been reported are acute eosinophilic pneumonia, carbon monoxide poisoning, increase in respiratory rate, transmission of infection, and acute reduction in lung function. Long-term effects include increased risk of lung cancer, chronic obstructive pulmonary disease, asthma exacerbation, and deterioration in lung function. The article describes the history and background of WP smoking, prevalence, factors responsible for the promotion of WP smoking, and the acute and long-term effects on the respiratory system.
