Primary heart neoplasms are rare occurring with an estimated incidence of 0.0017-0.19%. Myxoma is the most prevalent primary heart tumor. The right atrium is an unusual localization, occurring only in 15-20% of myxoma cases. We report a rare case of a massive right atrial myxoma causing tricuspid valve obstruction and presenting as syncope and exertional dyspnea. This case illustrates the influence of myxoma's size, position and mobility as well as patient's body posture and respiration to the development of signs and symptoms. Three-dimensional echocardiography proved useful in surgery planning, allowing a better definition of the tumor outline and attachment.

Background: COVID-19 was declared a pandemic by the World Health Organization (WHO) on March 11st, 2020. Responses to this crisis integrated resource allocation for the increased amount of infected patients, while maintaining an adequate response to other severe and life-threatening diseases. Though cardiothoracic patients are at high risk for Covid-19 severe illness, postponing surgeries would translate in increased mortality and morbidity. We reviewed our practice during

Candida endocarditis is a rare infection associated with high mortality and morbidity. There are still some controversies about Candida endocarditis treatment, especially about the treatment duration. We report a case of a Candida parapsilosis endocarditis that presented as a lower limb ischemia. The patient was surgically treated with a cryopreserved homograft aortic replacement. We used intravenous fluconazole 800 mg as initial treatment, followed with 12 months of 400 mg fluconazole per os. The patient outcome was good.

The availability of population-based epidemiological data on the incident risk of stroke is very scarce in Argentina and other Latin American countries. In response to the priorities established by the World Health Organization and the United Nations, PREVISTA was envisaged as a population-based program to determine the risk of first-ever and recurrent stroke and transient ischemic attack incidence and mortality in Tandil, Buenos Aires, Argentina. The study will be conducted according to Standardized Tools for Stroke Surveillance (STEPS Stroke) methodology and will enroll all new (incident) and recurrent consecutive cases of stroke and transient ischemic attack in the City of Tandil between May 1st, 2013 and April 30, 2015. The study will include patients with ischemic stroke, non-traumatic primary intracerebral hemorrhage, subarachnoid hemorrhage, and transient ischemic attack. To ensure the inclusion of every cerebrovascular event during an observation period of two years, we will instrument an 'intensive screening program', consisting of a comprehensive daily tracking of every potential event of stroke or transient ischemic attack using multiple overlapping sources. Mortality would be determined during follow-up for every enrolled patient. Also, fatal community events would be screened daily through revision of death certificates at funeral homes and local offices of vital statistics. All causes of death will be adjudicated by an ad-hoc committee. The close population of Tandil is representative of a large proportion of Latin-American countries with low- and middle-income economies. The findings and conclusions of PREVISTA may provide data that could support future health policy decision-making in the region.

Background Covid‐19 was declared a pandemic by the World Health Organization (WHO) on 11 March 2020. Responses to this crisis integrated resource allocation for the increased amount of infected patients while maintaining an adequate response to other severe and life‐threatening diseases. Though cardiothoracic patients are at high risk for Covid‐19 severe illness, postponing surgeries would translate to increased mortality and morbidity. We reviewed our practice during the initial time of the pandemic, with emphasis on safety protocols. Methods From 11 March to 15 May 2020, 148 patients underwent surgery at the Department of Cardiothoracic Surgery of Centro Hospitalar Universitário de São João. The clinical characteristics of the patients were retrospectively registered, along with novel containment and infection prevention measures targeting the new coronavirus. Results The majority of adult cardiac patients were operated on an emergency basis. Hospital mortality was 1.9% (n = 2 patients). Most adult thoracic patients were admitted from home, with a diagnosis of neoplastic disease in 60% of patients. Hospital mortality was 3.3% (1 patient). Fifteen children underwent cardiothoracic surgery. There was no mortality. The infection prevention procedures applied, totally excluded the transmission of Covid‐19 in the department. Conclusion While guaranteeing a prompt response to emergent, urgent, and high priority cases, novel safety measures in individual protection, patients circuits, and preoperative diagnoses of symptomatic and asymptomatic infection were adopted. The surgical results corroborate that it was safe to undergo cardiothoracic surgery during the initial time of the Covid‐19 pandemic. The new policies will be maintained while the virus stays in the community.

Descending necrotising mediastinitis has been linked with significant morbidity and mortality. We report two recent cases and discuss the surgical management of this serious disease. Complete thoracic drainage was achieved through a median stemotomy, allowing a fast recovery.
