Role of different echocardiographic modalities in the assessment of microvascular function in women with ischemia and no obstructive coronary arteries.

This review summarizes current knowledge about echocardiographic modalities used to assess microvascular function and left ventricular (LV) systolic function in women with ischemia and no obstructive coronary arteries (INOCA). Although the entire pathophysiological background of this clinical entity still remains elusive, it is primarily linked to microvascular dysfunction which can be assessed by coronary flow velocity reserve. Subtle impairments of LV systolic function in women with INOCA are difficult to assess by interpretation of wall motion abnormalities. LV longitudinal function impairment is considered to be an early marker of subclinical systolic dysfunction and can be assessed by global longitudinal strain quantification.

The preoperative assessment of patients with valvular heart disease as a comorbidity.

In patients with valvular heart disease planned for any type of surgery preoperative evaluation and preparation are especially important for a successfull outcome of the surgery. Preoperative preparation and intraoperative treatment of patients with valvular heart disease are different de-Spending on the type of valvular disease: aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation or mitral valve prolapse. In this paper we have outlined the criteria for evaluating the severity of valvular disease, given that the risk in surgery is proportional to the degree of valvular disease. Also, given that the risk in surgery is also directly proportional to the type and extent of non cardiac surgery, it will be presented recommendations for intraoperative monitoring, with the purpose of evaluating patient's hemodynamic state, as well as recommendations for perioperative treatment of hypotension, tachycardia, and other hemodynamic disturbances. In the paper we will separately discuss bacterial endocarditis profilaxys which can occur after the surgery of patients with valvular disease. Since the patients with valvular disease, and especially the ones with implanted prosthetic valve or heart arrhythmia, are usually on oral anticoagulation therapy, it will be given recommendations for treatment of patients on oral anticoagulation therapy as part of preoperative preparations.
