In-hospital and late outcomes of patients undergoing percutaneous mitral valvuloplasty in a center with intermediate volume of structural procedures

ABSTRACTBackgroundPercutaneous mitral valvuloplasty is the treatment of choice for rheumatic mitral stenosis with favorable anatomy, for its ability to prevent complications inherent to a surgical procedure, while maintaining effectiveness. It is necessary to promote comparisons between the results obtained by the procedure performed at referral centers with high patient inflow and at institutions with lower volume and fewer patients, which represents the main objective of this study.MethodsThirty-one consecutive patients undergoing percutaneous mitral valvuloplasty were analyzed from September 2006 to January 2015. Immediate procedural success and late event-free survival rates were evaluated, defined as cardiovascular death or need for a new mitral valve intervention.ResultsThe mean age was 40.9 ± 14.2 years, with a predominance of females (96.8%). The mean Wilkins and Block score was 8.1 ± 1.2. All procedures were performed using the Inoue technique, with an immediate success rate of 90.3%. At mean follow-up of 6.8 ± 2.5 years, seven events (22.6%) were observed: two cardiovascular deaths, four surgeries for mitral valve replacement, and one mitral commissurotomy.ConclusionsIn a hospital with intermediate procedure volume, the results of percutaneous mitral valvuloplasty in the treatment of rheumatic mitral stenosis with favorable anatomy were comparable to those achieved by high-volume centers

Perfil clínico e angiográfico de pacientes jovens submetidos à intervenção coronária percutânea primária

ResumoIntroduçãoO atual declínio observado na taxa de mortalidade entre pacientes com infarto do miocárdio com supradesnivelamento do segmento ST pode ser atribuído não apenas a maior utilização de estratégias de reperfusão, mas também a uma mudança no perfil demográfico dessa população, notadamente à redução em sua média de idade.MétodosForam analisados retrospectivamente todos os pacientes submetidos à intervenção coronária percutânea primária no período de abril de 2010 a dezembro de 2014. O objetivo primário foi a caracterização dos fatores de risco mais prevalentes, a natureza angiográfica das lesões, os aspectos técnicos do procedimento e a evolução clínica hospitalar de pacientes jovens, com idade ≤ 45 anos, comparando‐os àqueles com idade > 45 anos.ResultadosDentre 489 pacientes com diagnóstico de infarto agudo do miocárdio, 54 tinham idade ≤ 45 anos e 435, idade > 45 anos. Pacientes jovens exibiram maior prevalência de tabagismo e obesidade, enquanto pacientes > 45 anos eram mais propensos a apresentar hipertensão arterial sistêmica, diabetes melito, dislipidemia e infarto do miocárdio antigo. Intervenção coronária percutânea primária em jovens associou‐se ao uso de menor quantidade de cateteres‐guia, menor tempo de fluoroscopia e maior porcentual de implante direto de stent. Pacientes jovens exibiram boa evolução hospitalar, com reduzida taxa de eventos cardíacos adversos (3,7% vs. 9,2%; p = 0,30).ConclusõesPacientes com idade ≤ 45 anos representaram aproximadamente 10% dos casos de infarto do miocárdio com supradesnivelamento do segmento ST e exibiram elevada prevalência de fatores de risco modificáveis.AbstractBackgroundThe current decline observed in mortality rate among patients with ST‐segment elevation acute myocardial infarction can be attributed not only to the increased use of reperfusion strategies, but also to a change in the demographic profile of this population, notably the reduction in mean age.MethodsWe retrospectively reviewed all patients undergoing primary percutaneous coronary intervention in the period from April 2010 to December 2014. The primary objective was the characterization of the most prevalent risk factors, the angiographic nature of the lesions, the technical aspects of the procedure, and in‐hospital clinical outcomes in patients aged ≤ 45 years, comparing them to those aged > 45 years.ResultsAmong 489 patients with acute myocardial infarction, 54 were ≤ 45 years, and 435 were > 45 years. Young patients exhibited a higher prevalence of smoking and obesity, while patients > 45 years were more likely to have hypertension, diabetes mellitus, dyslipidemia, and previous myocardial infarction. Primary percutaneous coronary intervention in young patients was associated with the use of fewer guide catheters, shorter fluoroscopy time, and higher percentage of direct stent implantation. Young patients exhibited good in‐hospital outcomes, with lower rate of adverse cardiac events (3.7% vs. 9.2%; p = 0.30).ConclusionsPatients aged ≤ 45 years accounted for approximately 10% of cases of ST‐segment elevation acute myocardial infarction and exhibited high prevalence of modifiable risk factors
