ABSTRACT
We present an asymptomatic pregnant patient with congenitally corrected transposition of the great arteries and severe atrioventricular bioprosthesis regurgitation - with increased maternal and fetal risk due to volume overload. She was considered high risk for reintervention and was submitted to an off-label post-partum transcatheter valve-in-valve implantation with a Sapiens 3 valve. The procedure was successful, and she remains asymptomatic 30 months after - and even went through another successful pregnancy.

Lipid control is one of the most important secondary cardiovascular prevention targets. Although cardiovascular disease is the most common cause of death in both sexes, women are less likely to receive guideline-recommended secondary prevention medications. To compare sex disparities in dyslipidemia control in a secondary prevention population, we retrospectively analysed all patients who participated in a Coronary Rehabilitation Program (CRP) after an acute coronary syndrome (ACS) from January 2011 to October 2019. Of a total of 881 patients enrolled, mean age 55.0-year-old, 16.1% were female. At hospital admission, females and males had similar mean LDL-levels. Female patients received more high intensity therapy during follow-up (67.8% vs 53.9% at baseline, p = 0.015; 75.6% vs 59.0% after CRP, p = 0.003; and 79.8% vs 65.1% at 1-year-follow-up, p = 0.007). At the end of the CRP, male patients exhibit a better control of LDL [82.0 vs 75.6 mg/dL, t(597) = 2.4, p = 0.016)] with 12.8% vs 16.4% below 55 mg/dL and 29.8% vs 44.5% below 70 mg/dL (p = 0.008). At 1-year follow-up, both sexes exhibited similar LDL-control thanks to a worsening control of the male population (81.9 vs 80.6 mg/dL, t(540) = 0.52, p = 0.605). Only 13.3% of females had LDL below 55 mg/dL (vs 12.9%, p = 0.921) and 32.5% below 70 mg/dL (vs 37.0%, p = 0.432). This real-life study showed that guideline recommended LDL target is not achieved in the majority of patients. Unlike other reports, there were more women receiving more potent anti-dyslipidemic therapy. Nevertheless, women showed a poor control of LDL-concentration after three months of ACS and a similar control after 1-year.

Resumo Fundamento Os distúrbios de condução (DC) são a complicação mais frequente após a substituição da válvula aórtica transcateter (TAVR) e ainda não há consenso sobre seu tratamento. Objetivo Avaliar novos DC e implante de marca-passo definitivo (MPD) após a TAVR e avaliar a porcentagem de estimulação ventricular (EV) até 1 ano de acompanhamento. Métodos Pacientes submetidos a TAVR de outubro de 2014 a novembro de 2019 foram cadastrados; pacientes com MPD anterior foram excluídos. Dados clínicos, do procedimento, do ECG e do MPD foram coletados até 1 ano após o implante. O nível de significância adotado para a análise estatística foi 0,05%. Resultados Um total de 340 indivíduos foram submetidos a TAVR. O DC mais comum foi bloqueio de ramo esquerdo novo (BRE; 32,2%), sendo que 56% destes foram resolvidos após 6 meses. O bloqueio do ramo direito (BRD) foi o maior fator de risco para bloqueio atrioventricular avançado (BAV) [RC=8,46; p<0,001] e implante de MPD [RC=5,18; p<0,001], seguido de BAV de baixo grau prévio [RC=2,25; p=0,016 para implante de MPD]. Em relação às características do procedimento, válvulas de gerações mais recentes e procedimentos de válvula-em-válvula foram associados a menos DC. No total, 18,5% dos pacientes tiveram MPD implantado após a TAVR. Na primeira avaliação do MPD, pacientes com BAV avançado tinham uma porcentagem mediana de EV de 80%, e, após um ano, de 83%. Em relação aos pacientes com BRE e BAV de baixo grau, a EV mediana foi mais baixa (6% na primeira avaliação, p=0,036; 2% após um ano, p = 0,065). Conclusão O BRE foi o DC mais frequente após a TAVR, com mais da metade dos casos se resolvendo nos primeiros 6 meses. O BRD foi o principal fator de risco para BAV avançado e implante de MPD. O BAV avançado foi associado a uma porcentagem mais alta de EV no acompanhamento de 1 ano.
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<0.001] and PPM implantation [OR=5.18, p<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.

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.
