An alternative method of indexation in aortic stenosis: height-adjusted effective orifice area : An observational prospective study.

Background: Although indexing effective orifice area (EOA) by body surface area (BSA) is recommended, this method has several disadvantages, since it corrects by acquired fatty tissue. Our aim was to analyze the value of EOA normalized by height for predicting cardiovascular outcome in patients with aortic stenosis (AS).

Methods: Patients with AS (peak velocity > 2 m/s) evaluated in our echocardiography laboratory between January 2015 and June 2018 were prospectively enrolled.

Early recruitable coronary collaterals preserve miocardial viability in late presentation infarctions.

Background: Previous studies showed conflicting results regarding the contribution of coronary collateral circulation (CCC) to myocardial perfusion and function in the setting of myocardial infarction (MI). In the primary angioplasty era, the role of CCC in these studies may have been influenced by the effect of early reperfusion. The true impact of CCC could be clarified by studying its effect on nonreperfused patients.

Effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on left ventricular remodelling and longitudinal strain: a prospective observational study.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) lower cardiovascular events in type 2 diabetes mellitus (T2DM) patients, although the mechanisms underlying these benefits are not clearly understood. Our aim was to study the effects of SGLT2i on left ventricular remodelling and longitudinal strain.

Methods: Between November 2019 and April 2020, we included 52 patients with T2DM ≥ 18 years old, with HbA1c between 6.

Outcome implication of sex-related effective orifice area normalized to body size in aortic stenosis.

Introduction: Although several echocardiographic parameters have different values according to sex, there are no studies in echocardiographic variables of aortic stenosis (AS) severity. Our aim was to evaluate the sex-related prognosis of several echocardiographic parameters in AS.

Methods: Two hundred and twenty-five patients with at least moderate AS (effective orifice area [EOA] ≤ 1.

Prognostic value of aortic valve area normalized to body size in native aortic stenosis.

Introduction And Objectives: Although guidelines recommend the use of a cutoff value of 0.60 cm/m for aortic valve area (AVA) normalized to body surface area (BSA) for severe aortic stenosis, there is little evidence of its prognostic value. Our aim was to test the value of AVA normalized to body size for outcome prediction in aortic stenosis.

Acceleration Time and Ratio of Acceleration Time to Ejection Time in Aortic Stenosis: New Echocardiographic Diagnostic Parameters.

Background: Inconsistencies between gradients and aortic valve area are frequent in the echocardiographic evaluation of aortic stenosis (AS). Assessing AS severity is essential for the correct management of the disease. The aim of this study was to evaluate whether ejection dynamics, particularly acceleration time (AT) and the ratio of AT to ejection time (ET), could be diagnostic parameters in patients with AS.

Invasive assessment of coronary microvascular dysfunction in hypertrophic cardiomyopathy: the index of microvascular resistance.

We present a review of microvascular dysfunction in hypertrophic cardiomyopathy (HCM) and an interesting case of a symptomatic familial HCM patient with inducible ischemia by single photon emission computed tomography. Coronary angiography revealed normal epicardial arteries. Pressure wire measurements of fractional flow reserve (FFR), coronary flow reserve (CFR) and index of microvascular resistance (IMR) demonstrated a significant microcirculatory dysfunction.
