Use of Levosimendan as bridge therapy to surgical correction of post-infarction ventricular septal defect: a case report.

Objective: Ventricular septal defect (VSD) is an uncommon but frequently fatal complication following acute myocardial infarction. In medically treated patients, mortality rates exceed 90%, while the surgical repair is associated with better outcomes, even though optimal surgical timing is still under debate.

Case Report: We present the case of a 78-years-old man with no previous remarkable cardiological history admitted to our Emergency Department with the diagnosis of anterior ST-elevation myocardial infarction and significant reduction of left ventricular ejection fraction.

Coronary microvascular dysfunction beyond microvascular obstruction in ST-elevation myocardial infarction: Functional and clinical correlates.

Objectives: To retrospectively characterize clinical predictors and impact on left ventricular (LV) ejection fraction (EF) of microvascular dysfunction (MVD) beyond microvascular obstruction (MVO), in 49 consecutive patients (58 ± 11 years), with successfully treated ST-elevation myocardial infarction.

Methods: By myocardial contrast echocardiography, MVD was considered as myocardial segments with delayed/patchy opacification, while MVO as areas without any opacification. Both MVD and MVO were planimetered and expressed as percentage of total LV wall area.

The Effects of Granulocyte Colony-Stimulating Factor in Patients with a Large Anterior Wall Acute Myocardial Infarction to Prevent Left Ventricular Remodeling: A 10-Year Follow-Up of the RIGENERA Study.

Background: the RIGENERA trial assessed the efficacy of granulocyte-colony stimulating factor (G-CSF) in the improvement of clinical outcomes in patients with severe acute myocardial infarction. However, there is no evidence available regarding the long-term safety and efficacy of this treatment.

Methods: in order to evaluate the long-term effects on the incidence of major adverse events, on the symptom burden, on the quality of life and the mean life expectancy and on the left ventricular (LV) function, we performed a clinical and echocardiographic evaluation together with an assessment using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the Seattle Heart Failure Model (SHFM) at 10-years follow-up, in the patients cohorts enrolled in the RIGENERA trial.

Coronary slow flow is associated with a worse clinical outcome in patients with Takotsubo syndrome.

Objective: Patients with Takotsubo syndrome (TTS) present an acute microvascular dysfunction that leads to an impaired myocardial perfusion and, in more severe forms, an impaired epicardial flow. However, clinical relevance of a delayed coronary flow, the coronary slow flow (CSF), has never been investigated. We studied the prognostic value of CSF occurring in the acute phase of TTS.

Rationale, experimental data, and emerging clinical evidence on early and preventive use of levosimendan in patients with ventricular dysfunction.

Acute ventricular dysfunction (AVD) is a complex condition with substantial morbidity and mortality, still featuring unique therapeutic challenges. Levosimendan is a calcium sensitizer and ATP-dependent potassium channel opener that was developed as an inodilating drug for the treatment of acute heart failure and cardiogenic shock. Differently from other more widely used inotropic agents, levosimendan has some exclusive characteristics, in terms of mechanisms of action, pharmacodynamic profile, and haemodynamic effects.
