1. Introduction There are currently a wide modalities of interventional strategies – both transcatheter and surgical – which can be indicated for patients with valvular heart diseases (VHD), with the objective of reducing the morbidity and mortality. The correct timing for indication and the type of interventional treatment are linked to the precise anatomical and functional diagnosis of the VHD, and comprehensive global evaluation of the patient.

A male patient with flu-like symptoms and tomography and laboratory diagnosis of severe acute respiratory syndrome. He developed acute cardiac dysfunction during admission and was submitted to a cardiac magnetic resonance imaging examination, which confirmed acute myocarditis, indicating cardiac involvement by coronavirus disease 2019. A review and discussion about coronavirus disease 2019-related cardiac manifestations are reported, focusing on the imaging findings to make diagnosis.

Predicting mortality in patients undergoing transcatheter aortic valve implantation (TAVI) remains a challenge. To evaluate the performance of 5 risk scores for cardiac surgery in predicting the 30-day mortality among patients of the Brazilian Registry of TAVI. The Brazilian Multicenter Registry prospectively enrolled 418 patients undergoing TAVI in 18 centers between 2008 and 2013. The 30-day mortality risk was calculated using the following surgical scores: the logistic EuroSCORE I (ESI), EuroSCORE II (ESII), Society of Thoracic Surgeons (STS) score, Ambler score (AS) and Guaragna score (GS). The performance of the risk scores was evaluated in terms of their calibration (Hosmer-Lemeshow test) and discrimination [area under the receiver-operating characteristic curve (AUC)]. The mean age was 81.5 ± 7.7 years. The CoreValve (Medtronic) was used in 86.1% of the cohort, and the transfemoral approach was used in 96.2%. The observed 30-day mortality was 9.1%. The 30-day mortality predicted by the scores was as follows: ESI, 20.2 ± 13.8%; ESII, 6.5 ± 13.8%; STS score, 14.7 ± 4.4%; AS, 7.0 ± 3.8%; GS, 17.3 ± 10.8%. Using AUC, none of the tested scores could accurately predict the 30-day mortality. AUC for the scores was as follows: 0.58 [95% confidence interval (CI): 0.49 to 0.68, p = 0.09] for ESI; 0.54 (95% CI: 0.44 to 0.64, p = 0.42) for ESII; 0.57 (95% CI: 0.47 to 0.67, p = 0.16) for AS; 0.48 (95% IC: 0.38 to 0.57, p = 0.68) for STS score; and 0.52 (95% CI: 0.42 to 0.62, p = 0.64) for GS. The Hosmer-Lemeshow test indicated acceptable calibration for all scores (p > 0.05). In this real world Brazilian registry, the surgical risk scores were inaccurate in predicting mortality after TAVI. Risk models specifically developed for TAVI are required.

Preamble In Brazil, cardiovascular diseases represent an important cause of mortality. From 2010 to 2019, 28% of deaths recorded by the Information Technology Department of the Brazilian Unified Health System resulted from this group of diseases. Within the measures involved in tackling this public health problem, strategies for rational use of resources have been boosted by advances in diagnostic imaging techniques. Notably, computed tomography and magnetic resonance imaging have expanded their potential within the diagnostic and prognostic arsenal in cardiovascular [...] Preamble In Brazil, cardiovascular diseases represent an important cause of mortality.
