- Innovative approach to a functional mediastinal paraganglioma with anomalous coronary supply: a case reportPublication . Luz, André; Amaral, Cláudia; Silveira, Inês; Trêpa, MariaBackground: Mediastinal paragangliomas (PGs) are rare and particularly challenging neuroendocrine tumours. Clinical presentation is heterogeneous and tumour resection can be challenging due to bleeding and the risk of catecholamine surges in functional tumours. Case summary: A 36-year-old man with multiple cardiovascular risk factors was admitted with subacute heart failure. Investigations revealed a large non-metastatic functional mediastinal PG irrigated mainly by a left circumflex coronary anomalous feeder branch. The surgical risk was deemed very high due to patient comorbidities, tumour vascularization, and close relation to major thoracic structures. A multidisciplinary team decided to perform embolization of the anomalous coronary branch followed by peptide-receptor radionuclide therapy with 177-LuDOTATE aiming to decrease tumour size and perioperative risk. Follow-up studies showed a reduction in tumour vascularization, size, and hormonal production. Discussion: The innovative strategy of combining embolization of the anomalous feeder branch with radionuclide therapy proved to be a promising approach.

- Cardiovascular Complications of COVID-19 InfectionPublication . Trêpa, Maria; Hipólito-Reis, António; Oliveira, MarioIntroduction: Reports of cardiovascular complications related to the COVID-19 infection have been frequent. Methods: Narrative review for relevant articles on the topic. The classic cardiovascular risk factors, like age, obesity, diabetes, and hypertension are associated with adverse outcomes in COVID-19 patients. Cardiovascular complications can have a diverse clinical presentation including silent myocardial injury, acute coronary syndromes, thromboembolism, cardiac arrhythmias, and heart failure. There are multiple mechanisms of cardiac injury that are not mutually exclusive. The approach to diagnosis and management should be carried out according to usual practice, while considering the particularities of COVID-19 infection. Conclusion: The interaction between SARS-CoV-2 and the heart is complex and is manifested in multiple ways. Regardless of the clinical presentation, cardiac complications convey a worse prognosis. Patients should be actively monitored and treated accordingly.
- Cardiovascular rehabilitation in patients aged 70-year-old or older: benefits on functional capacity, physical activity and metabolic profile in younger vs. older patientsPublication . Fontes-Oliveira, Marta; Trêpa, Maria; Rodrigues, Patrícia; Preza-Fernandes; Magalhães, Sandra; Cabral, Sofia; Santos, Mario; Torres, SeveroBackground: The benefits of exercise-based cardiac rehabilitation (EBCR) programs in post-acute myocardial infarction (AMI) patients have been demonstrated. Our aim was to assess the impact of EBCR in ≥ 70-years-old vs. younger post-AMI patients. Methods: We retrospectively evaluated patients who underwent a supervised EBCR protocol, twice a week during 6-12 weeks. We evaluated changes in several outcomes based on pre- and post-CRP assessments. Results: Of a total of 1607 patients, 333 (21%) were ≥ 70-years-old. After the EBCR, an overall improvement on functional capacity, daily physical activity, lipid profile, body mass index, glycated hemoglobin (HbA1c), N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and C-reactive protein was observed in both younger and older patients (P < 0.05). Older patients showed a smaller benefit on the increment of daily physical activity and lipid profile improvement, but a larger reduction in NT-pro-BNP. In the multivariate analysis, only improvements on daily physical activity and HbA1c were dependent on age. Conclusion: As their younger counterparts, older patients, significantly improved functional capacity, metabolic parameters and level of daily physical activity after EBCR.
- Echocardiographic Assessment of Right Ventriculo-arterial Coupling: Clinical Correlates and Prognostic Impact in Heart Failure Patients Undergoing Cardiac Resynchronization TherapyPublication . Bragança, Bruno; Trêpa, Maria; Baggen Santos, Raquel; Silveira, Inês; Fontes-Oliveira, Marta; Sousa, Maria João; Hipólito-Reis, António; Torres, Severo; Santos, MarioBackground: Right ventriculo-arterial coupling (RV-PA) can be estimated by echocardiography using the ratio between tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP) and it has prognostic value in the general heart failure (HF) population. We aimed to study the clinical correlates and prognostic value of RV-PA in HF patients undergoing cardiac resynchronization therapy (CRT). Methods: We retrospectively studied 70 HF patients undergoing CRT implantation. Results: RV-PA coupling was estimated by TAPSE/PASP ratio using baseline echocardiography. Non-response to CRT was defined as improvement of left ventricular ejection fraction < 5% in a follow-up echo 6-12 months after CRT. Those with lower TAPSE/PASP ratios (worse RV-PA coupling) had higher NT-proBNP concentrations and increased E/e' ratio. TAPSE/PASP ratio and PASP, but not TAPSE, predicted nonresponse to CRT with TAPSE/PASP ratio showing the best discriminative ability with a sensitivity of 76% and specificity of 71%. Among these parameters, PASP independently predicted all-cause mortality. Conclusions: RV-PA coupling estimated by TAPSE/PASP ratio was associated with established prognostic markers in HF. It numerically outperformed PASP and TAPSE in predicting the response to CRT. Our data suggest that this simple and widely available echocardiographic parameter conveys significant pathophysiological and prognostic meaning in HF patients undergoing CRT.
- Predictors of In-Hospital Mortality after Recovered Out-of-Hospital Cardiac Arrest in Patients with Proven Significant Coronary Artery Disease: A Retrospective StudyPublication . Trêpa, Maria; Bastos, Samuel; Fontes-Oliveira, Marta; Costa, Ricardo; Dias-Frias, André; Luz, André; Dias, Vasco; Santos, Mario; Torres, SeveroIntroduction: Recovered Out-of-Hospital Cardiac Arrest (rOHCA) population is heterogenous. Few studies focused on outcomes in the rOHCA subgroup with proven significant coronary artery disease (SigCAD). We aimed to characterize this subgroup and study the determinants of in-hospital mortality. Methods: Retrospective study of consecutive rOHCA patients submitted to coronary angiography. Only patients with SigCAD were included. Results: 60 patients were studied, 85% were male, mean age was 62.6 ± 12.1 years. In-hospital mortality rate was 43.3%. Patients with diabetes and history of stroke were less likely to survive. Significant univariate predictors of in-hospital mortality were further analysed separately, according to whether they were present at hospital admission or developed during hospital evolution. At hospital admission, initial non-shockable rhythm, low-flow time>12min, pH<7.25mmol/L and lactates >4.75mmol/L were the most relevant predictors and therefore included in a score tested by Kaplan-Meyer. Patients who had 0/4 criteria had 100% chance of survival till hospital discharge, 1/4 had 77%, 2/4 had 50%, 3/4 had 25%. Patients with all 4 criteria had 0% survival. During in-hospital evolution, a pH<7.35 at 24h, lactates>2mmol/L at 24h, anoxic brain injury and persistent hemodynamic instability proved significant. Patients who had 0/4 of these in-hospital criteria had 100% chance of survival till hospital discharge, 1/4 had 94%, 2/4 had 47%, 3/4 had 25%. Patients with all 4 criteria had 0% survival. Contrarily, CAD severity and ventricular dysfunction didn't significantly correlate to the outcome. Conclusion: Classic prehospital variables retain their value in predicting mortality in the specific group of OHCA with SigCAD. In-hospital evolution variables proved to add value in mortality prediction. Combining these simple variables in risk scores might help refining prognostic prediction in these patients's subset.

Araiza-Garaygordobil, D; Montalto, C; Martinez-Amezcua, P; Cabello-Lopez, A; Gopar-Nieto, R; Alabrese, R; Almaghraby, A; Catoya-Villa, S; Chacon-Diaz, M; Kaufmann, C C; Corbi-Pascual, M; Deharo, P; El-Tahlawi, M; Elgohari-Abdelwahab, A; Guerra, F; Jarakovic, M; Martinez-Gomez, E; Moderato, L; Montero, S; Morejon-Barragan, P; Omar, A M; Jorge-Pérez, P; Przybyło, P; Selim, E; Sinan, U Y; Stratinaki, M; Tica, O; Trêpa, Maria; Uribarri, A; Uzokov, J; Wilk, K; Czerwińska-Jelonkiewicz, K; Sionis, A; Gierlotka, M; Leonardi, S; Krychtiuk, K A; Tavazzi, GBackground: COVID-19 has challenged the health system organization requiring a fast reorganization of diagnostic/therapeutic pathways for patients affected by time-dependent diseases such as acute coronary syndromes (ACS). Aim: To describe ACS hospitalizations, management, and complication rate before and after the COVID-19 pandemic was declared. Design: Ecological retrospective study. Methods: We analyzed aggregated epidemiological data of all patients > 18 years old admitted for ACS in twenty-nine hub cardiac centers from 17 Countries across 4 continents, from December 1st, 2019 to April 15th, 2020. Data from December 2018 to April 2019 were used as historical period. Results: A significant overall trend for reduction in the weekly number of ACS hospitalizations was observed (20.2%; 95% confidence interval CI [1.6, 35.4] P = 0.04). The incidence rate reached a 54% reduction during the second week of April (incidence rate ratio: 0.46, 95% CI [0.36, 0.58]) and was also significant when compared to the same months in 2019 (March and April, respectively IRR: 0.56, 95%CI [0.48, 0.67]; IRR: 0.43, 95%CI [0.32, 0.58] p < 0.001). A significant increase in door-to-balloon, door-to-needle, and total ischemic time (p <0.04 for all) in STEMI patents were reported during pandemic period. Finally, the proportion of patients with mechanical complications was higher (1.98% vs. 0.98%; P = 0.006) whereas GRACE risk score was not different. Conclusions: Our results confirm that COVID-19 pandemic was associated with a significant decrease in ACS hospitalizations rate, an increase in total ischemic time and a higher rate of mechanical complications on a international scale.
