RESUMEN

A 54-year-old patient with a medical history of hypertension, dyslipidemia, and diabetes underwent mitral valve replacement surgery with a biologic valve. During a chest computed tomography scan for breast neoplasia staging, a reduced luminal filling in the left atrium (3.6 cm) was unexpectedly found, prompting further cardiac evaluation. The patient was referred to the emergency department experiencing shortness of breath and fatigue, which improved after furosemide administration, and remaining stable throughout hospitalization. A transesophageal echocardiogram was performed the following day and revealed a biologic mitral valve prosthesis slightly displaced toward the left ventricle with an average transprosthetic gradient of 7 mmHg. Notably, a sizable intermediate echogenic mass measuring 3.0 cm × 3.5 cm was detected and attached to the prosthesis ring in a lateral and posterior position, within the left atrium. A mild degree of periprosthetic regurgitation was also noted. Given the substantial suspicion that the observed mass was a thrombus, the patient was commenced on anticoagulation therapy while awaiting cardiac magnetic resonance imaging for better characterization of the mass. Over 4 weeks, the thrombus notably decreased in size, disappearing entirely by the 6th week. This case highlights the significance of employing multiple imaging techniques in managing cardiac masses. The incidental discovery of the mass, its characterization, and subsequent management through anticoagulation, followed by confirmation and monitoring through echocardiogram, underscore the importance of a multimodal approach in diagnosing and treating such conditions.

RESUMEN

BACKGROUND: The shock index (SI), reflecting heart rate (HR) to SBP ratio, is established for predicting adverse outcomes in acute coronary syndrome (ACS) patients. Exploring the age shock index (ASI), obtained by multiplying SI with age, could offer further insights into ACS prognosis. OBJECTIVES: Assess ASI's effectiveness in predicting in-hospital death in individuals with ACS. METHODS: This study encompassed patients with acute myocardial infarction, drawn from a national registry spanning October 2010 to January 2022. The optimal ASI threshold was established using receiver operating characteristic (ROC) curve analysis. The primary outcome was in-hospital mortality. RESULTS: A total of 27 312 patients were enrolled, exhibiting a mean age of 66 ±â€…13 years, with 72.3% being male and 47.5% having ST-elevation myocardial infarction. ROC analysis yielded an area under the curve (AUC) of 0.80, identifying the optimal ASI cutoff as 44. Multivariate regression analysis, adjusting for potential confounders, established ASI ≥ 44 as an independent predictor of in-hospital death [hazard ratio: 3.09, 95% confidence interval: 2.56-3.71, P  < 0.001]. Furthermore, ASI emerged as a notably superior predictor of in-hospital death compared to the SI (AUC ASI  = 0.80 vs. AUC SI  = 0.72, P  < 0.0001), though it did not outperform the Global Registry of Acute Coronary Events (GRACE) score (AUC ASI  = 0.80 vs. AUC GRACE  = 0.85, P  < 0.001) or thrombolysis in myocardial infarction (TIMI) risk index (AUC ASI  = 0.80 vs. AUC TIMI  = 0.84, P  < 0.001). CONCLUSION: The ASI offers an expedient mean to promptly identify ACS patients at elevated risk of in-hospital death. Its simplicity and effectiveness could render it a valuable tool for early risk stratification in this population.

RESUMEN

Despite constant medical evolution, the reimbursement policy of Portuguese National Health Service (NHS) for the study and risk stratification of coronary heart disease has remained unchanged for several decades. Lack of adjustment to contemporary clinical practice has long been evident. However, the recent publication of the European Guidelines for diagnosis and treatment of chronic coronary syndromes further highlighted this gap and the urgent need for a change. Prompted by these Guidelines, the Working Group on Nuclear Cardiology, Cardiac Magnetic Resonance and Cardiac CT, the Working Group on Echocardiography and the Working Group on Stress Pathophysiology and Cardiac Rehabilitation of the Portuguese Society of Cardiology, began a process of joint reflection on the current limitations and how these recommendations could be applied in Portugal. To this end, the authors suggest that the new imaging methods (stress echocardiogram, cardiac computed tomography and cardiac magnetic resonance), should be added to exercise treadmill stress test and myocardial perfusion scintigraphy in the available exam portfolio within the Portuguese NHS. This change would allow full adoption of European guidelines and a better use of tests, according to clinical context, availability and local specificities. The adoption of clinical guidance standards, based on these assumptions, would translate into a qualitative improvement in the management of these patients and would promote an effective use of the available resources, with potential health and financial gains.

RESUMEN

INTRODUCTION: Cardiac rehabilitation (CR) programs have a central role in cardiovascular medicine, encompassing a comprehensive framework able to holistically address various facets of cardiovascular disease. However, several obstacles to their optimal application have been reported. Over the years, the Portuguese Society of Cardiology has periodically conducted a national survey on the state of CR in Portugal. OBJECTIVES: This study reports the results of the 2019 survey on CR. METHODS: In December 2019 a voluntary questionnaire was sent to centers offering CR programs, consisting of several items concerning this intervention. RESULTS: In 2019, 25 centers provided structured CR programs. A total of 2182 patients underwent phase II programs, representing an increase of 13% from the previous survey. Of these, 67.2% were referred due to ischemic heart disease, and 14.5% due to heart failure. Acute coronary syndromes (ACS) comprised 49.3% of referrals, leading to an estimated 9.3% CR coverage. A total of 606 patients participated in phase III programs (a decrease of 37%). Drop-out rates ranged from 0-68%; 91% of centers presented drop-out rates <25%. CONCLUSION: The present survey shows an increase in the number of centers and patients undergoing phase II CR, and an increase in the estimated CR coverage after ACS. Despite this, the level of increase means that overall patient representation remained below the optimal range, while the data also showed a decrease in the number of patients in phase III programs. These findings reinforce the importance of optimization of CR entry and maintenance, in order to improve the uptake of this pivotal intervention.

RESUMEN

INTRODUCTION AND OBJECTIVES: In December 2019, SARS-CoV-2, was discovered as the agent of COVID-19 disease. Cardiac arrhythmias have been reported as frequent but their incidence is unknown. The aim of this research was to assess the real incidence of cardiac arrhythmias among COVID-19 patients admitted to Portuguese hospitals and to understand the underlying prognostic implications. METHODS: The Portuguese Association of Arrhythmology, Pacing and Electrophysiology (APAPE) conducted a survey in Portuguese hospitals to assess the occurrence of arrhythmias in COVID-19 patients, their clinical characteristics, the use of experimental therapies and the impact on QT interval. RESULTS: Twenty hospitals participated, reporting 692 hospitalized patients. An arrhythmic episode occurred in 81 (11.7%) and 64 (79%) had detailed information on these episodes. New onset arrhythmias occurred in 41 (64%) patients, 45 (70.3%) male, median age 73.5 (61-80.3) years. There were 51 (79.7%) with associated comorbidities, mainly arterial hypertension (41, 64.1%). Of 53 patients (82.3%) on experimental therapy, 7 (10.9%) had an increased QTc interval. Regarding arrhythmias, two patients (3.1%) had ventricular tachycardia, 5 (7.8%) sinus bradycardia, 17 (26.6%) paroxysmal supraventricular tachycardia and 40 (62.5%) atrial fibrillation or flutter. At the time of reporting, there had been no deaths due to arrhythmic syndrome or related complications. CONCLUSIONS: In a population of COVID-19 patients. The incidence of cardiac arrhythmias is high but not associated with increased cardiac mortality although it does though occur frequently in extremely ill patients and with multiple organ failure. Regardless of the use of experimental drugs, the incidence of ventricular arrhythmias is low and atrial fibrillation and other supraventricular arrhythmias are the most prevalent arrythmias.


INTRODUÇÃO E OBJETIVOS: Em dezembro de 2019, o SARS-CoV-2 foi descoberto como agente da doença Covid-19. As arritmias cardíacas são reportadas como frequentes, mas a sua incidência é desconhecida. O objetivo deste trabalho foi entender a incidência de arritmias em doentes Covid-19 tratados em hospitais portugueses e entender as suas implicações prognósticas. MÉTODOS: A Associação Portuguesa de Arritmologia, Pacing e Electrofisiologia (APAPE) conduziu um inquérito em hospitais portugueses, documentando a ocorrência de arritmias em doentes com Covid-19, as suas caraterísticas clínicas, o uso de terapêutica experimental e o seu impacto no intervalo QT. RESULTADOS: Participaram 20 hospitais, reportando 692 doentes hospitalizados. Ocorreram episódios arrítmicos em 81 (11,7%), 64 (79%) com informação adicional. Documentaram-se arritmias de novo em 41 (64%) doentes, 45 (79%) do sexo masculino, idade mediana 73,5 (61-80,3) anos. Destes, 51 (79,7%) tinham comorbilidades associadas, maioritariamente hipertensão arterial (41, 64,1%). Dos 53 (82,3%) doentes sob terapêutica experimental, 7 (10,9%) tiveram aumento do intervalo QTc. Tiveram taquicardia ventricular 2 (3,1%) doentes, 5 (7,8%) bradicardia sinusal, 17 (26,6%) taquicardia paroxística supraventricular e 40 (7,8%) fibrilhação ou flutter auricular. Nenhum doente teve morte por causa arrítmica ou complicações associadas, à data do registo. CONCLUSÕES: Numa população de doentes com Covid-19, a incidência de arritmias é elevada, mas não associada a aumento de mortalidade cardíaca, apesar da ocorrência mais frequente em doentes graves e com falência multiorgânica. Independentemente do uso de terapêuticas experimentais, a incidência de arritmias ventriculares é baixa e a fibrilhação auricular e outras arritmias supraventriculares são as arritmias mais prevalentes.

RESUMEN

Tricuspid stenosis (TS) is an uncommon complication of transvenous ventricular pacing. We present a case of TS developed 14 years after pacemacker implantation. The etiology of stenosis appeared to be inflammation and fibrosis of tricuspid valve (TV) secondary to leaflet perforation by the pacemacker lead and it was managed successfully with surgical valvuloplasty. Iatrogenic TS may occur more frequently than is clinically suspected and it should be considered in any patient with endocardial leads presenting with right heart failure.
