Comparison of myocardial tissue reperfusion of inferior wall and a right ventricle among patients after primary angioplasty for an inferior myocardial infarction with right ventricular infarction.

Background: Impaired myocardial tissue reperfusion affects prognosis of patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI) and can be identified by ST-segment analysis. To date, evaluation of the myocardial tissue reperfusion of the right ventricle (RV) among the patients treated with PCI for inferior STEMI with right ventricular infarction (RVI) has not been made yet.

Methods: Patients with inferior STEMI were screened for RVI.

Lumen and calcium characteristics within calcified coronary lesions. Comparison of computed tomography coronary angiography versus intravascular ultrasound.

Introduction: Computed tomography coronary angiography (CTCA) is a diagnostic method used for exclusion of coronary artery disease. However, lower accuracy of CTCA in assessment of calcified lesions is a significant factor impeding applicability of CTCA for assessment of coronary atherosclerosis.

Aim: To provide insight into lumen and calcium characteristics assessed with CTCA, we compared these parameters to the reference of intravascular ultrasound (IVUS).

Prognostic value of renal fractional flow reserve in blood pressure response after renal artery stenting (PREFER study).

Background: The aim of our study was to determine a potential relationship between resting translesional pressures ratio (Pd/Pa ratio), renal fractional flow reserve (rFFR) and blood pressure response after renal artery stenting.

Methods: Thirty five hypertensive patients (49% males, mean age 64 years) with at least 60% stenosis in angiography, underwent renal artery stenting. Translesional systolic pressure gradient (TSPG), Pd/Pa ratio (the ratio of mean distal to lesion and mean proximal pressures) and hyperemic rFFR - after intrarenal administration of papaverine - were measured before stent implantation.

Comparison of usefulness of percutaneous coronary intervention guided by angiography plus computed tomography versus angiography alone using intravascular ultrasound end points.

The aim of our study was to assess the impact of coronary computed tomographic angiographic (CTCA) guidance on outcomes of percutaneous coronary intervention (PCI). The study was a randomized single-center trial. Consecutive eligible patients with CTCA-detected significant coronary lesions who were scheduled for PCI were randomized to an angiographically guided versus an angiographically plus computed tomographically guided (ACTG) group.

Functionally driven complete vs incomplete revascularisation in multivessel coronary artery disease--long-term results from a large cohort.

Background: Complete revascularisation (CR) by means of percutaneous coronary intervention (PCI) has been associated with better long-term prognosis than incomplete revascularisation (IR) in several clinical trials. However, in the published studies, the completeness of myocardial revascularisation has been judged mainly on an anatomical basis, while including criteria directed at functionally driven IR might lead to different results.

Aim: To examine the potential value of functionally driven IR in a large cohort of patients with multivessel coronary artery disease (MVD) undergoing PCI.
