Minimally invasive mitral valve surgery is effective, with excellent late results. The durability of minimally invasive mitral valve repair compared favorably with conventional full sternotomy methods at late follow-up.

The assessment of frailty may enhance the preoperative workup and offer an optimized risk stratification measure in patients undergoing cardiothoracic procedures even though the reporting standards of calibration and classification measures have been relatively poor.

Cardiopulmonary exercise variables and plasma NT-proBNP are associated more with NYHA functional class and SAQ score than with MLHF score. When combined, SAQ score, NT-proBNP, and etiology of heart failure can satisfactorily predict peak oxygen uptake.

In a large, community-based sample of women nationwide, this comprehensive analysis shows remarkable geographic variation in risk factors, which provides opportunities to improve and reduce a woman's CVD risk. Further investigation is required to understand the reasons behind such variation, which will provide insight toward tailoring preventive interventions to narrow gaps in CVD risk reduction in women.

Subvalvular techniques are gaining ground as adjunct procedures for addressing ischaemic mitral regurgitation. The aim of this study was to describe the different techniques and assess their results. A systematic review of the literature was performed. The end points of interest were recurrence of mitral regurgitation, cardiac events and early and late echocardiographic measurements. After initial screening, 450 articles were identified, of which 24 provided the best available evidence on the topic. The different subvalvular techniques had similar mortality rates when compared with the standard restrictive annuloplasty. Recurrence of mitral regurgitation was of lower degree and the remodelling process was better for these techniques. Reoperation rates were also quite low. The subvalvular techniques showed superiority, addressing more successfully the leaflet tethering. However, larger randomized studies are needed to confirm these early positive results.

Peak VO2 is independently associated both with QoL and activity capacity. In addition to peak VO2, LVEF is independently associated with QoL, and LA with activity capacity.

Left main stem (LMS) disease is known to be a poor prognostic factor in terms of morbidity or mortality. Traditionally, it has been treated with constitution of bypass to provide required haemodynamic stability. We searched the literature for evidence on off-pump (OFP) surgery for treating this high-risk group of patients focusing in our review on postoperative outcomes, concerns and controversies. The majority of the studies identified showed favourable or equal outcomes of OFP when compared to conventional approach. All of the studies, apart from two, which showed lower incidence of postoperative deaths, demonstrated equal mortality rates. Stroke rates were found less in three studies. Less blood transfusions, inotropic use and length of study has been also demonstrated. The main concerns of OFP surgery are: haemodynamic instability and less complete revascularization. Main controversies are: same or favourable outcomes despite lower number of grafts with OFP surgery and less stroke rates despite manipulation of aorta with side-clamping. Despite these concerns and controversies OFP surgery has been proven to be feasible and safe as demonstrated by results from numerous studies.
