Abstract

A 57-year-old male with previously known severe primary mitral regurgitation was admitted to the intensive care unit (ICU) due to massive venous thromboembolism, associated with right ventricular dysfunction and two large mobile right atrial thrombi. Due to deterioration in his clinical condition despite standard treatment with unfractionated heparin, it was decided to use an ultra-slow low-dose thrombolysis protocol, which consisted of a 24-hour infusion of 24 mg of alteplase at a rate of 1 mg per hour, without initial bolus. The treatment was continued for 48 consecutive hours, with clinical improvement and resolution of the intracardiac thrombi and no complications. One month after ICU admission, successful mitral valve repair surgery was conducted. This case demonstrates that ultra-slow low-dose thrombolysis is a valid bailout treatment option in patients with large intracardiac thrombi refractory to the standard approach., (Copyright © 2023.

Abstract

Introduction and Objectives: Heart failure (HF) has significant morbidity and mortality, and its prevalence will continue to increase in the future. This unfavorable evolution requires reflection as well as recommendations and decisions based on expert critical and strategic appraisal., Methods: In the Acceleration on Heart Failure Empowerment and Awareness - the Portuguese Challenge (ATHENA-PT) study, a range of strategic factors that represent the strengths, weaknesses, threats, and opportunities (SWOT) of HF in Portugal were established. These factors were assessed quantitatively by experts, to create a final SWOT matrix for the management and prevention of HF in Portugal and to outline recommendations., Results: For HF management, the panel emphasized the following strategic recommendations: (i) reimbursement of natriuretic peptides testing in primary healthcare; (ii) reimbursement of Doppler assessment in echocardiographic studies and promotion of detailed information in reports; (iii) intervention to improve the prognosis of patients with HF with preserved ejection fraction; (iv) ensuring effective healthcare transition between hospital and ambulatory units, using checklists/protocols; and (v) reinforcement and commitment to the training of primary health physicians and to the cardiac rehabilitation of patients. For the prevention of HF, the following recommendations/proposals were proposed: (i) campaigns to raise awareness of cardiovascular disease risk factors; (ii) promotion of physical exercise and healthy eating; and (iii) avoidance of therapeutic inertia in the management of risk factors., Conclusions: The acknowledgment of various strategic factors and their prioritization by experts made it possible to create and reinforce a range of new strategic recommendations for the management and prevention of HF., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

Abstract

Introduction and Objectives: Acute total occlusion of the unprotected left main coronary artery (LMCA) is a dramatic event. There are limited data regarding this population. We aimed to describe the clinical presentation and outcomes of patients and to determine predictors of in-hospital mortality., Methods: This retrospective study included patients presenting with acute (<12 h) myocardial infarction due to total occlusion of the LMCA (TIMI flow 0) between January 2008 and December 2020 in three tertiary hospitals., Results: During this period, 11036 emergent coronary angiographies were performed, 59 (0.5%) of which revealed acute total occlusion of the LMCA. Patients' mean age was 61.2 (SD±12.2) years and 73% were male. No patients had left dominance. At presentation, 73% were in cardiogenic shock, aborted cardiac arrest occurred in 27% and 97% underwent myocardial revascularization. Primary percutaneous coronary intervention was performed in 90% of cases and angiographic success was achieved in 56% of procedures, while 7% of patients underwent surgical revascularization. In-hospital mortality was 58%. Among survivors, 92% and 67% were alive after one and five years, respectively. After multivariate analysis, only cardiogenic shock and angiographic success were independent predictors of in-hospital mortality. Use of mechanical circulatory support and presence of well-developed collateral circulation were not predictive of short-term prognosis., Conclusion: Acute total occlusion of the LMCA is associated with a dismal prognosis. Cardiogenic shock and angiographic success play a major role in predicting the prognosis of these patients. The effect of mechanical circulatory support on patient prognosis remains to be determined., (Copyright © 2023. Publicado por Elsevier España, S.L.U.)

Abstract

Introduction: Spontaneous coronary artery dissection (SCAD) represents 1-4% of all acute coronary syndromes (ACS), and is a particularly important cause among young women and individuals with few cardiovascular risk factors., Objectives: To characterize clinical background, therapeutic management and clinical outcomes in a SCAD population., Methods: We retrospectively analyzed all consecutive patients diagnosed with SCAD at a tertiary center between August 2009 and May 2020, with a median follow-up of 40 months (IQR 14-95 months). SCAD was classified according to the Saw angiographic SCAD classification., Results: A total of 36 patients were included, 94% female, mean age 51 years (±11 years). A trigger was only detected in 8% and associated conditions in 31% of patients, mainly inflammatory or autoimmune systemic diseases and migraine. Most patients had non-ST-elevation ACS and 33% presented with ST-elevation ACS. The most frequent culprit lesion was the left anterior descending (LAD) artery (67%); mid to distal segments were the most affected (94%) and type 2 dissection the most prevalent (60%). Almost all patients were successfully medically managed, with only four undergoing percutaneous intervention. During follow-up, ischemic events recurred in 15% of patients and no patient died. Patients with type 2 dissection exhibited lower risk of recurrence compared to type 1 (p=0.049, OR=0.13)., Conclusion: SCAD patients were mainly young or middle-aged women; the LAD artery was the most affected vessel and type 2 dissection the most prevalent. This report showed for the first time a correlation between type 2 SCAD and lower risk of recurrence., (Copyright © 2023 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U.

Abstract

Introduction: In patients with cryptogenic stroke, one of the most frequently found abnormalities is patent foramen ovale (PFO). Percutaneous 'deviceless' systems based on surgical suture-mediated PFO closure have recently been introduced and show a favorable efficacy and safety profile with clear advantages., Objectives: To present procedural details of the technique and baseline characteristics of patients who underwent the procedure in our center., Methods: A single-center prospective observational registry was established between February 2020 and February 2021, to assess the safety, efficacy and possible advantages of a novel percutaneous PFO closure system (NobleStitch® EL). Patient and PFO characteristics as well as technical features were collected for analysis., Results: Twenty-three patients were considered suitable for this technique after transesophageal echocardiography. Their mean age was 51 years and 69.5% were women. Most patients (91.3%) had a history of cryptogenic stroke. PFO closure with the NobleStitch® system was successfully performed in all patients. All procedures were performed under local anesthesia and fluoroscopic monitoring. The mean duration of the procedure was 52 min and median contrast dose used was 187 ml. Median radiation dose absorbed per patient was 61.5 Gy cm 2 . All patients were discharged asymptomatic 24 hours after the procedure with no peri- or postprocedural complications recorded., Conclusion: Suture-mediated PFO closure represents a valid and safe alternative to traditional umbrella-like devices, and is feasible in the majority of PFO anatomies. Follow-up information, results of larger series and clinical trials may possibly validate this technique as the first choice for PFO closure., (Copyright © 2022 Sociedade Portuguesa de Cardiologia.

Abstract

Background: Conduction disturbances (CD) are the most frequent complication after transcatheter aortic valve replacement (TAVR), and there continues to be a lack of consensus on their management., Objective: To assess new CD and permanent pacemaker (PPM) implantation after TAVR and to evaluate the ventricular pacing percentage (VP) up to 1 year of follow-up., Methods: Patients who underwent TAVR from October 2014 to November 2019 were enrolled; patients with previous PPM were excluded. Clinical, procedure, ECG, and PPM data were collected up to 1 year after implantation. The significance level adopted in the statistical analysis was 0.05., Results: A total of 340 patients underwent TAVR. The most frequent CD was the new left bundle branch block (LBBB; 32.2%), which 56% resolved after 6 months. Right bundle branch block (RBBB) was the biggest risk factor for advanced atrioventricular block (AVB) [OR=8.46; p&lt;0.001] and PPM implantation [OR=5.18, p&lt;0.001], followed by previous low-grade AVB [OR=2.25; p=0.016 for PPM implantation]. Regarding procedure characteristics, newer generation valves and valve-in-valve procedures were associated with fewer CDs. Overall, 18.5% of patients had a PPM implanted post-TAVR. At first PPM evaluation, patients with advanced AVB had a median percentage of VP of 80% and 83% at one year. Regarding patients with LBBB plus low-grade AVB, median VP was lower (6% at first assessment, p=0.036; 2% at one year, p = 0.065)., Conclusion: LBBB was the most frequent CD after TAVR, with more than half being resolved in the first six months. RBBB was the major risk factor for advanced AVB and PPM implantation. Advanced AVB was associated with a higher percentage of VP at 1 year of follow-up.

Abstract

Introduction and Objectives: Coronary artery fistulas (CAFs) are rare abnormalities, often detected incidentally during invasive coronary angiography (ICA). While most are clinically silent, they can cause significant morbidity. We aimed to investigate the clinical, angiographic and management features of CAFs in a population undergoing ICA., Methods: We retrospectively reviewed the data of all ICAs conducted in our department between May 2008 and January 2020 and selected those with CAFs. Clinical, angiographic, therapeutic and follow-up data were obtained from medical records., Results: A total of 55 patients with CAFs (35 male, median age 64 years) were identified among 32 174 ICAs. The majority (n=37) had a single fistula. CAFs arose most frequently from the left anterior descending artery (LAD), followed by the right coronary and left circumflex coronary arteries. The most frequent drainage site was the pulmonary artery. Fourteen patients had fistulas originating from both left and right coronary systems. Seven had concomitant congenital cardiovascular disorders. The majority (n=40) were incidental findings. Chest pain was the most common symptom attributable to CAFs and heart murmur the most frequent sign. Conservative management was the main approach (n=40). Eight patients underwent transcatheter closure and seven underwent surgical ligation (six of those during surgery for another heart condition), with no periprocedural mortality., Conclusions: In our series, the prevalence of CAFs was 0.2%. The majority originated from the LAD and the pulmonary artery was the main drainage site. In patients undergoing intervention, both percutaneous and surgical techniques were safe and effective., (Copyright © 2022. Publicado por Elsevier España, S.L.U.)

Abstract

Introduction and Objectives: The coronavirus SARS-CoV-2 (COVID-19) pandemic has been an unmatched challenge to global healthcare. Although the majority of patients admitted with acute coronary syndrome (ACS) may not be infected with COVID-19, the quarantine and public health emergency measures may have affected this particular high risk group. The objective of this study is to assess the impact of the early period of the COVID-19 pandemic on ACS admissions and clinical course in a tertiary care hospital in Portugal's most affected region., Methods: This retrospective, case-control study included patients admitted with a diagnosis of ACS during March and April 2020 (pandemic group) and in the same period in 2019 (control group). Clinical course and complications were also assessed., Results: During the pandemic, there were fewer ACS admissions but presentation was more severe, with a larger proportion of acute ST-elevation myocardial infarctions (54.9% vs. 38.8%, p=0.047), higher maximum troponin levels and greater prevalence of left ventricular systolic dysfunction at discharge (58.0% vs. 35.0%, p=0.01). In this population, although not statistically significant, it was observed a delay between the onset of symptoms and percutaneous coronary intervention, which may traduce a deferred search for urgent medical care during the pandemic., Conclusion: The lockdown phase of COVID-19 pandemic was associated with fewer and more severe ACS in a Tertiary Care Hospital in Portugal's most affected region by the pandemic., (Copyright © 2021 Sociedade Portuguesa de Cardiologia.

Abstract

We report a case of temporary pacemaker lead malposition in the left ventricle crossing the interventricular septum (IVS). The majority of described cases occur due to a patent foramen ovale and are frequently incidental findings. A course across the IVS is rarely found and this complication with temporary leads is not even reported in the literature. This very rare location entails a risk of dangerous complications associated with left-to-right flow after lead removal. Echocardiography was an essential tool to diagnose the lead's course inside the heart and enabled secure removal of the lead with cardiac surgery backup., (Copyright © 2020 Sociedade Portuguesa de Cardiologia.

block vertebrae
Abstract

We present a case of a 15-year-old boy in whom an x-ray of the vertebral column was performed to investigate dorsal hipercyphosis. The exam showed partial block vertebrae in D8-D9. Block vertebrae may be congenital or acquired, partial or complete. Most of the times it is an incidental x-ray finding.

cervical ribs
Abstract

We present a case of a 17-year-old adolescent with a painless hard palpable mass in the left supraclavicular fossa. Thoracic x-ray revealed a left cervical rib. A normal variant of the ribs must be considered in the differential diagnosis of a supraclavicular mass. In most cases x-ray is sufficient for the diagnosis.

Abstract

INTRODUÇÃO: A colonografia por TC (CTC) tem um papel diagnóstico controverso. Objectivos: Determinação da eficácia e da experiência dos pacientes com a CTC comparando com a colonoscopia óptica (CO). Métodos: Estudo prospectivo, cego para os avaliadores, com recrutamento de 100 pacientes com indicação para CO, que foram submetidos a CTC prévia. Resultados: Excluídos 6 pacientes por impossibilidade de realização da CTC ou da CO. A sensibilidade (S) e a especificidade (E) da CTC na detecção de pacientes com pólipos ≥10 mm foi 57% (intervalo de confiança [CI] de 95%, 12-86%) e 96% (IC95%, 43-63%); pólipos no global S = 49% (IC95%, 12-86%) e E = 67% (IC95%; 57-77%); entre 6-9 mm S = 31% (IC95%, 6-56%) e E = 80% (IC95%, 71-89%) e ≤ 5 mm S = 18% (IC95%, 7-31%) e E = 88% (IC95%, 71-89%). A CTC não detectou 3 lesões planas e 1 dos 2 tumores observados na CO; 56% dos pacientes preferiram a CTC. Conclusões: Neste estudo, a CTC mostrou sensibilidade insatisfatória para pólipos, apesar de melhor quando de dimensões significativas. A especificidade para pólipos foi elevada. Salientam-se as falhas para cancro e lesões planas. Os pacientes manifestaram preferência pela CTC. BACKGROUND: CT colonography (CTC) has a controversial diagnostic role in the diagnosis of colorectal lesions. aims: In this study we prospectively assess the accuracy and patient experience with CTC compared with optical colonoscopy (OC) in a evaluator-blinded study of 100 patients referred for colonoscopy who previously performed CTC. results: Six patients were excluded due to impossibility to perform CTC or OC. Sensitivity (S) and specificity (E) of CTC for detecting polyps ≥10 mm was 57% (95% confidence interval [IC], 12-86%) and 96% (95%CI, 43-63%); overall polyps S = 49% (95%CI, 12-86%) and E = 67% (95%CI; 57-77%); between 6-9 mm S = 31% (95%CI, 6-56%) and E = 80% (IC95%, 71-89%); ≤ 5 mm S = 18% (95%CI, 7-31%) and E = 88% (95%CI, 71-89%). CTC missed 3 flat lesions and 1of the 2 cancers detected on OC. 56% patients expressed preference for CTC. Conclusions: In this study, overall estimated sensitivity of CTC was inadequate to detect polyps for polyps, although it was better in the detection of polyps with significant dimensions. Estimated specificity of CTC was high for polyps. CTC had a relevant number of missed flat lesion and cancer. Patients preferred CTC over OC.
