Percutaneous mitral repair: current and future devices

Mitral regurgitation (MR) is the second most common valvular heart disease and its prevalence is increasing with population ageing. In the recent years we have witnessed the development of several transcatheter devices to correct MR in patients at high-risk for surgery. The majority of evidence regarding safety and efficacy of this new therapy comes from MitraClip studies. However, new alternatives on the field of valve repair have emerged with promising results. The aim of this review is to portrait the landscape of transcatheter mitral repair alternatives, from currently used devices to those that will have a role in the near future

Frailty, disability and comorbidity: different domains lead to different effects after surgical aortic valve replacement in elderly patients

OBJECTIVES: Frailty syndrome predicts adverse outcomes after surgical aortic valve replacement. However, disability or comorbidity is frequently associated with preoperative frailty evaluation. The effects of these domains on early and late outcomes were analysed. METHODS: A prospective study including patients aged >/=75 years with symptomatic severe aortic stenosis who received aortic valve replacement with or without coronary artery bypass grafting was conducted. We used the Cardiovascular Health Study Frailty Phenotype to assess frailty, the Lawton-Brody index to define disability and the Charlson comorbidity index (CCI) to evaluate comorbidity. RESULTS: Frailty was identified in 57 (31%), dependence in 18 (9.9%) and advanced comorbidity (CCI >/= 4) in 67 (36.6%) of the 183 enrolled patients. Operative mortality (1.6%), transfusion rate and duration of stay increased in patients with CCI >/=4 (P /=75 years is a safe procedure with low mortality rates. Operative outcomes are mainly affected by comorbidities. The main influence of survival occurs throughout the first year, and an improved functional status prevents any progression towards disabilities, which could potentially benefit long-term outcomes.
