Randomized Controlled Trial Multicenter Study Clinical TrialPercutaneous coronary intervention for cardiogenic shock in the SHOCK trial.
We examined the clinical, angiographic, and procedural characteristics determining survival after percutaneous coronary intervention (PCI) for cardiogenic shock. ⋯ Restoration of coronary blood flow is a major predictor of survival in cardiogenic shock. Benefit appears to extend beyond the generally accepted 12-h post-infarction window. Surgery should be considered in shock patients with severe mitral insufficiency or multivessel disease not amenable to relatively complete percutaneous revascularization.

Time interval between onset of mitral inflow and onset of early diastolic velocity by tissue Doppler: a novel index of left ventricular relaxation: experimental studies and clinical application.
The goal of this study was to examine the diagnostic utility of the time to onset of early (Ea) diastolic velocity of the mitral annulus by tissue Doppler (TD) in comparison with the time to onset of mitral inflow (T(Ea-E)) for the assessment of left ventricular (LV) relaxation. ⋯ T(Ea-E) is a useful novel index of LV relaxation. It can be used to identify patients with diastolic dysfunction and predict PCWP.

Role of left atrial appendage obliteration in stroke reduction in patients with mitral valve prosthesis: a transesophageal echocardiographic study.
The aim of our study was to assess whether left atrial appendage (LAA) ligation in patients undergoing mitral valve replacement is associated with the risk of future embolisms. ⋯ Our study shows that LAA ligation during surgery of mitral valve replacement, performed in a high-risk population, is consistent with a reduction of the risk of late embolism and supports this technique if a mitral valve replacement is indicated.
