“…The importance of the Wilkins et al 10 echocardiographic scores is demonstrated in the results obtained in percutaneous mitral balloon valvuloplasty 30 . Because our percutaneous mitral balloon valvuloplasty postsurgical mitral commissurotomy group had higher echo scores than the primary percutaneous mitral balloon valvuloplasty group, 7.7±1.5 versus 7.2±1.4 points (p=0.0158) and a tendency toward slightly better results in the primary percutaneous mitral balloon valvuloplasty group, we redivided the total 459 procedures into a patient group with echo scores ≤8 and a patient group with echo scores >8 to better study the influence of echocardiographic scores on the obtained results.…”

“…The following parameters were studied: age, sex, rhythm, preprocedure NYHA functional class, mitral valve, echo score 10 , preprocedure echo mitral valve area, pre-and postballoon valvuloplasty mean pulmonary artery pressure, pre-and postprocedure mean mitral gradient, pre-and postprocedure hemodynamic measured mitral valve area, and pre-and postprocedure mitral regurgitation. The data obtained in the 2 groups were compared.…”

“…The morphologic features of the mitral valve were categorized using the Wilkins echo score 13 and the total echocardiographic score was obtained by adding the scores for leaflet mobility, thickness, calcification, and subvalvular lesions. MVA was measured by direct planimetry in parasternal short-axis view, and continuous wave Doppler was used to calculate peak pressure gradient of tricuspid regurgitation.…”

Introduction and aim: Percutaneous mitral valvuloplasty (PMV) is an effective treatment option for mitral stenosis (MS), but its success is assessed on the basis of clinical and echocardiographic outcomes in studies with relatively short follow-up. We aimed to characterize a cohort of patients undergoing PMV with long-term follow-up and to determine independent predictors of post-PMV mitral re-intervention and event-free survival. Methods: We studied 91 consecutive patients with MS who underwent PMV with a median clinical follow-up duration of 99 months. Two endpoints were considered: post-PMV mitral re-intervention (PMV or mitral surgery) and a composite clinical events endpoint including cardiovascular death, mitral valve re-intervention and hospital admission due to decompensated heart failure. We compared patients who required post-PMV mitral re-intervention with those who did not during follow-up. Results: The study population included 83.5% females and mean age was 48.9 ± 13.9 years. The 1-, 3-, 5-, 7-and 9-year rates of clinical event-free survival were 93.0 ± 2.8%, 86.0 ± 3.9%, 81.0 ± 4.4%, 70.6 ± 5.6%, and 68.4 ± 5.8%, respectively. The 1-, 3-, 5-, 7-and 9-year rates of mitral re-intervention-free survival were 98.8 ± 1.2%, 97.5 ± 1.7%, 92.1 ± 3.1%, 85.5 ± 4.5%, and 85.5 ± 4.5%, respectively. The median time to mitral re-intervention was 6.2 years. Patients who required mitral re-intervention during follow-up were younger (43.3 vs. 51.2 years, p=0.04) and had higher pre-and post-PMV mitral gradient (14.9 vs. 11.5 mmHg, p=0.02 and 6.4 vs. 2.1 mmHg, p<0.001) and higher post-PMV mean pulmonary artery pressure (mPAP) (30.0 vs. 23.2 mmHg, p=0.01). In a Cox proportional hazards model, mPAP ≥25 mmHg was the sole predictor of both mitral re-intervention .528], p=0.025) and clinical events .260], p=0.039). PALAVRAS-CHAVEEstenose mitral; Valvuloplastia mitral percutânea; Prognóstico; Pressão média na artéria pulmonar A pressão média na artéria pulmonar após a valvuloplastia mitral percutânea é um preditor de mau prognóstico a longo prazo Resumo Introdução e objetivos: A valvuloplastia mitral percutânea (PMV) é uma opção eficaz para o tratamento da estenose mitral. Contudo, os resultados deste procedimento são baseados em estudos clínicos e ecocardiográficos com tempos de seguimento relativamente curtos. Os objetivos deste estudo são caracterizar uma população de doentes submetidos a PMV, realizar um seguimento clínico de longa duração e determinar os preditores independentes de reintervenção mitral após PMV e de sobrevida livre de eventos. Métodos: Foi estudada uma população de 91 doentes com estenose mitral tratada por PMV e realizou-se um seguimento clínico com a duração média de 99 meses. Foram pré-definidos dois endpoints: reintervenção mitral pós-PMV (PMV ou cirurgia mitral) e um endpoint clínico combinado que incluiu morte de causa cardiovascular, reintervenção mitral e internamento hospitalar por insuficiência cardíaca descompensada. Foi realizado um estudo comparativo entre os doentes que necessi...

“…(5) Rheumatic disease, in turn, is considered the most important causal determinant of valve diseases, as the scar from the inflammatory process that affects the follow-up of the heart during episodes of rheumatic fever causes deformation of the heart valves. (6) The cardiovascular changes associated with pregnancy and the postpartum period can contribute to the clinical worsening of these patients' condition and, often, to the initial diagnosis of a valve disease. (7) In this period, the circulating blood volume increases by about 30 to 50%.…”

Objective: Analyze the changes in the quality of life of cardiac patients during pregnancy and after birth and study the correlations between the sociodemographic and clinical characteristics and quality of life measures during the postpartum period. Methods: This prospective study included 33 pregnant women selected through non-probabilistic sampling. The research instrument was the SF-36 questionnaire. To compare the mean domain scores of the SF-36, Student's t-test was used, as well as Spearman's coefficient for possible correlations. Results: In comparison with the pregnancy, the assessed quality of life improved after birth, except in the domains general health status and vitality. The variable pregnancy planning indicated a positive correlation with the mental health domain and a negative correlation with emotional aspects in the postpartum period. Conclusion: After birth, the quality of life improved. Not planning the pregnancy contributed to improve the mental health, but aggravated the emotional aspects in the postpartum period. ResumoObjetivo: Analisar as mudanças na qualidade de vida em pacientes cardiopatas durante a gestação e após o parto, e estudar as correlações das características sociodemográficas e clínicas com medidas de qualidade de vida no puerpério. Métodos: Estudo prospectivo que incluiu 33 gestantes selecionadas por amostra não probabilística. O instrumento de pesquisa foi o questionário SF-36. Para a comparação das médias dos escores dos domínios do SF-36 foi utilizado o test t de Student e o coeficiente de Spearman para possíveis correlações. Resultados: Comparada à gestação, houve melhora na avaliação de qualidade de vida após o parto, exceto nos domínios estado geral de saúde e vitalidade. A variável planejamento da gestação indicou correlação positiva com o domínio saúde mental e negativa com aspectos emocionais no puerpério. Conclusão: Após o parto houve melhora na qualidade de vida. Não planejar a gestação contribuiu melhorou a saúde mental, mas agravou os aspectos emocionais no puerpério.
