- Congenital Heart Disease in Adults: Assessment of Functional Capacity Using Cardiopulmonary Exercise TestinPublication . Aguiar Rosa, S; Agapito, A; Soares, RM; Sousa, L; Oliveira, JA; Abreu, A; Silva, AS; Alves, S; Aidos, H; Pinto, MF; Cruz Ferreira, RAIM: The aim of the study was to compare functional capacity in different types of congenital heart disease (CHD), as assessed by cardiopulmonary exercise testing (CPET). METHODS: A retrospective analysis was performed of adult patients with CHD who had undergone CPET in a single tertiary center. Diagnoses were divided into repaired tetralogy of Fallot, transposition of the great arteries (TGA) after Senning or Mustard procedures or congenitally corrected TGA, complex defects, shunts, left heart valve disease and right ventricular outflow tract obstruction. RESULTS: We analyzed 154 CPET cases. There were significant differences between groups, with the lowest peak oxygen consumption (VO2) values seen in patients with cardiac shunts (39% with Eisenmenger physiology) (17.2±7.1ml/kg/min, compared to 26.2±7.0ml/kg/min in tetralogy of Fallot patients; p<0.001), the lowest percentage of predicted peak VO2 in complex heart defects (50.1±13.0%) and the highest minute ventilation/carbon dioxide production slope in cardiac shunts (38.4±13.4). Chronotropism was impaired in patients with complex defects. Eisenmenger syndrome (n=17) was associated with the lowest peak VO2 (16.9±4.8 vs. 23.6±7.8ml/kg/min; p=0.001) and the highest minute ventilation/carbon dioxide production slope (44.8±14.7 vs. 31.0± 8.5; p=0.002). Age, cyanosis, CPET duration, peak systolic blood pressure, time to anaerobic threshold and heart rate at anaerobic threshold were predictors of the combined outcome of all-cause mortality and hospitalization for cardiac cause. CONCLUSION: Across the spectrum of CHD, cardiac shunts (particularly in those with Eisenmenger syndrome) and complex defects were associated with lower functional capacity and attenuated chronotropic response to exercise.
- Implantação Percutânea de Válvulas Pulmonares: Experiência InicialPublication . Martins, JD; Ewert, P; Sousa, L; Freitas, I; Trigo, C; Jalles, N; Matos, P; Agapito, A; Cruz Ferreira, R; Pinto, MFOs doentes com cardiopatias submetidos a intervenção cirúrgica com implantação de condutos entre o ventrículo direito e a artéria pulmonar (VD-AP) podem desenvolver estenose e/ou insuficiência pulmonares ao longo do tempo. Nestas situações, associadas a arritmias cardíacas, disfunção ventricular direita e morte súbita, a re-intervenção cirúrgica permanece um desafio pela complexidade, mortalidade e morbilidade significativas. A implantação percutânea de válvulas pulmonares (IPVP), recentemente desenvolvida, representa uma abordagem alternativa para estes doentes. Objectivo: Reportar a experiência inicial com a IPVP, analisando o seu impacto no manejo destes doentes. Material e Métodos: Avaliação prospectiva dos dados clínicos, ecocardiográficos, da ressonância magnética, hemodinâmicos e angiográficos dos doentes submetidos a IPVP. Resultados: Seis doentes em classe funcional igual ou superior a II com disfunção do conduto VD-AP foram submetidos a IPVP. Tinham todos evidência de insuficiência e 5/6 de estenose. O procedimento consistiu na implantação de stents não cobertos no conduto para reforçar a sua rigidez e prevenir fracturas dos stents valvulados pulmonares Melody ® (Medtronic), que foram em seguida implantados com sucesso em todos. Obteve-se uma redução da pressão ventricular direita (94±27 para 44±7mmHg), da relação entre a pressão ventricular direita e esquerda (94±27 para 44±7%), do gradiente do conduto (65±28 para 11±4mmHg) e ausência de regurgitação pulmonar. O procedimento teve uma duração mediana de 180 minutos e decorreu sem complicações major. Os doentes tiveram alta em mediana dois dias após o procedimento. Na última avaliação, em mediana 7,8 meses após o procedimento, os doentes encontramse em classe funcional I (5) ou II (1), sem evidência não invasiva de disfunção do conduto. Conclusões: Os nossos resultados acompanham a experiência actual com esta modalidade terapêutica, com excelentes resultados nestes grupo de doentes complexos. A implementação da IPVP em doentes com cardiopatia congénita que requerem re-intervenção no tracto de saída do ventrículo direito tem-se revelado uma técnica promissora, embora complexa, alternativa a mais uma intervenção cirúrgica.
- Quality of Life Among Adults with Repaired Tetralogy of Fallot: a Literature ReviewPublication . Rodrigues, C; Silva, M; Cerejo, R; Rodrigues, R; Sousa, L; Trigo, C; Branco, LM; Agapito, A; Fragata, JTetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. Survival into adulthood is currently expected following surgical repair, leading to a growing population of adults with repaired TOF. In this literature review, we aim to summarize the current state of knowledge on the quality of life of adults with repaired TOF. A search was conducted on PubMed and results were reviewed for articles published between January of 2010 and June of 2020. Search terms included "Tetralogy of Fallot", "repaired", "adults" and "quality of life". For the subjective health status evaluation, most published studies used Short-Form-36. Most studies agree that physical complex status is poorer for adult patients with repaired TOF than for controls. Mental complex status was also lower. Patients reported similar satisfaction with their lives and levels of social participation. Most patients had a college or university degree. Higher education, male gender and having a partner were positively associated with being employed. Studies found no difference in the proportion of patients that are married or living with a partner, compared to control groups. Patients operated for TOF have a lower reproduction rate compared with the background population. A consistent finding of these studies is abnormal physical parameters compared to psychosocial issues. The diverse needs of adults with repaired TOF require a multidisciplinary care, that takes into consideration all aspects that affect their quality of life. Despite abnormal physical functional status, it is reassuring that most adult patients with TOF lead independent and productive lives.
- RoPE Score As a Predictor of Recurrent Ischemic Events After Percutaneous Patent Foramen Ovale ClosurePublication . Morais, LA; Sousa, L; Fiarresga, A; Martins, JD; Timóteo, AT; Viveiros Monteiro, A; Soares, C; Agapito, A; Pinto, MF; Cruz Ferreira, RThe benefits of patent foramen ovale (PFO) closure for cryptogenic stroke secondary prevention are still debated. The Risk of Paradoxical Embolism (RoPE) study developed a score to improve patient selection for this procedure. We proposed to assess the validity of this score to assess the prognostic impact of PFO closure.From 2000 to 2014, all consecutive patients submitted to PFO closure were included in a prospective registry in a university center. The primary endpoint was recurrent ischemic cerebrovascular events and the secondary endpoints were all-cause, neurological, and cardiac mortality rates and new-onset atrial fibrillation (NOAF) rates. In total, 403 patients were included in the study (women: 52.1%; mean age: 44.7 ± 10.9 years). The mean follow-up period was 6.4 ± 3.7 years. Immediate success was achieved in 97% patients. There were 23 (5.8%) ischemic cerebrovascular events, 8 (2.0%) deaths, and 17 (4.3%) NOAFs. The mean RoPE score was 6.10 ± 1.79. Smoker status, coronary artery disease, lower RoPE score, and higher left atrial dimensions were predictors of the primary endpoint. However, a lower RoPE score and coronary artery disease remained independent predictors in multivariate analysis.RoPE score was shown to be an independent predictor of recurrent ischemic cerebrovascular events, and a score of ≤ 6 was shown to identify patients with significantly higher risk of mortality and recurrent ischemic events.
- Successful Percutaneous Closure of a Residual Atrial Septal Defect Due to Device FailurePublication . Aguiar Rosa, S; Ferreira, F; de Sousa, L; Fiarresga, A; Martins, JD; Galrinho, A; Agapito, A; Fazendas, P; Pinto, MF; Cruz Ferreira, RA 39-year-old woman underwent uneventful percutaneous occlusion of an ostium secundum atrial septal defect (ASD) with a 22 mm Ultrasept ASD Occluder®. Transesophageal echocardiography (TEE) performed two years after implantation revealed a de novo residual left-to-right shunt through the correctly implanted device. Three-dimensional transesophageal echocardiography (3D TEE) further clarified this finding by showing a perforation of the device membrane coating. The patient underwent transcatheter closure of the residual shunt with a 20 mm Ultrasept PFO®device. The procedure was guided by fluoroscopy and real-time 3D TEE. At the end of the procedure 3D TEE documented correct device deployment with complete defect coverage and absence of residual shunt.
- Uhl's Disease: an Uncommon Presentation of a Rare DiseasePublication . Aguiar Rosa, S; Agapito, A; António, M; de Sousa, L; Oliveira, JA; Laranjo, S; Martins, S; Jalles Tavares, N; Pinto, MF; Cruz Ferreira, RUhl's disease, also known as Uhl anomaly, is a rare disease secondary to selective but uncontrolled apoptosis of right ventricular myocytes during the perinatal period, after complete cardiac development, leading to the absence of right ventricular myocardium and the direct apposition of endocardium to epicardium without a myocardial layer in between, resulting in right ventricular failure. The present paper describes a case of Uhl's disease with an uncommon presentation. A 28-year-old man was admitted with dyspnea and cyanosis. Transthoracic echocardiography showed severe dilation of the right chambers, impaired right ventricular systolic function and a large ostium secundum atrial septal defect (ASD). Cardiac catheterization revealed pulmonary hypertension, with increased pulmonary capillary wedge pressure (mean 19mmHg) and Qp:QS 0.88:1. At this point, the authors considered that a main diagnosis of ASD could not explain the clinical features and hemodynamic data. A primary disease of the right ventricle was the most likely hypothesis and cardiac magnetic resonance imaging was performed, which demonstrated an extremely thin-walled right ventricle, with almost complete absence of right ventricular free wall myocardium, compatible with Uhl's disease.
