Sudden death is probably the most important challenge of modern cardiology. Not only because of the large number of deaths it causes, but also because of the social impact it causes. It is currently a major public health problem worldwide. The objective of this study is to present a near-clinic of sudden death in a 14-yearold female patient with a history of hypertrophic cardiomyopathy and corset use due to scoliosis who was brought to the emergency room after having suffered a sudden loss of consciousness. In the emergency room, cardiorespiratory arrest is diagnosed and cardiopulmonary resuscitation is performed immediately, not recovering the patient. The enormous challenge posed by the SDC in this century, justified by an increase in the incidence and prevalence of cardiovascular diseases in the coming decades worldwide, makes it necessary to review the current approaches in its approach.

Endothoracic goiter is rare and mostly affects women between the fifth and sixth decade of life. A case of endothoracic goiter is presented in a 63-year-old man who smoked and presented with cough, dyspnea, and easy fatigue. A chest X-ray and CT scan were performed and an endothoracic goiter was diagnosed. A medial sternotomy with total thyroidectomy was performed. The biopsy revealed Thyroid Nodular Hyperplasia with degenerative changes. The patient evolved favorably. The accurate diagnosis helped effective treatment and satisfactory evolution of the patient. Knowledge about this disease contributes to better management of it.

Pulmonary thromboembolism (PTE) is a disease that is difficult to diagnose, and is a problem in the global health system. It is one of the complications described in COVID-19. We present a case of a 49-year-old man, with a history of being a smoker who, ten days after having suffered from COVID 19, begins with right hemithorax pain, cough with yellowish expectoration, slight shortness of breath and tiredness on exertion. interpreted as post_COVID pneumonia and antibiotic treatment is indicated. He does not improve and an EKG is performed which shows rapid response atrial fibrillation. An AndioCT is performed with which he is diagnosed with bilateral pulmonary thromboembolism. It evolves towards healing with treatment with Fraxiheparin. Pulmonary thromboembolism is a feared complication of COVID-19, which requires rapid diagnosis to ensure adequate treatment to achieve patient recovery and prevent death.

Aortic dissection is infrequent and affects mainly males. We present a 44-year-old male patient with a history of arterial hypertension who presented chest pain which was alleviated spontaneously, in the guardhouse a restless patient was seen, with pain in the upper abdomen, BP 170/100, saturation 98%, FC 100x´, FR 20x´, oliguria. Complementary tests were indicated and while the patient was on guard duty, he suffered sudden death. Aortic dissection is life threatening, an immediate diagnosis is essential, although in many cases it is carried out postmortem.
