The aim of our study was to assess the diagnostic accuracy of a global longitudinal strain and strain rate (GLS, GLSR) and mean radial strain and strain rate (MRS, MRSR) of the left ventricle to predict multivessel disease. In 113 patients, who underwent coronary angiography, left ventricular deformation was analysed by speckle-tracking based velocity vector imaging. In three standard apical views strain and strain rate curves were generated corresponding with two opposite basal, mid, and apical segments. The negative peaks of systolic strain and strain rate from 18 curves were averaged as GLS and GLSR. Similarly, in short axis view 6 negative systolic peaks were averaged and considered as MRS and MRSR. Four subgroups were defined: (1) without significant coronary stenosis, 0-vessel disease (0VD), (2) single-vessel disease (1VD), (3) double-vessel disease (2VD), and (4) triple-vessel disease (3VD). In comparison with patients without significant coronary artery disease, all deformation indexes were significantly decreased in patients with 3VD. The left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) showed lower significance level as deformation parameters. MRSR was the strongest predictor of multivessel disease. Receiver-operating characteristic curves (ROC) showed that MRSR had the highest diagnostic accuracy. Comparing ROC areas, MRSR had significantly higher diagnostic accuracy than LVEF and WMSI. The results of our study show that global deformation indexes have a good diagnostic accuracy in differentiating multivessel disease. MRSR tended to be better in identification of 3VD than traditional indexes of global and regional left ventricular function.

Slovakia. To evaluate procedural effi cacy and safety. BACKGROUND: Atrial fi brillation increases the risk of stroke. While anticoagulation therapy can reduce the risk of stroke, it is associated with bleeding risk and often unsatisfactory prescribed. Most thrombi form in the left atrium appendage, hence left atrium appendage occlusion may be a suitable therapeutic alternative for these patients. METHODS: This is an observational, retrospective, single-centre, case-series study including 30 patients with atrial fi brillation at a high risk of stroke, undergoing left atrial appendage occlusion from June 2015 to December 2018. RESULTS: The left atrial appendage was successfully closed in 29 (96.7 %) patients. Three months after the procedure, 4 patients had small leaks (< 2 mm). No complications were reported so far. Prior to the procedure, patients mostly received low molecular weight heparin (53.3 %). Three months after the procedure, patients mostly received acetylsalicylic acid (60.7 %) and clopidogrel (32.1 %). CONCLUSION: Left atrial appendage occlusion was shown to be an effective and safe alternative to anticoagulation therapy in patients with atrial fi brillation, at a high risk of stroke and bleeding. The procedure is safe, when performed carefully even by less experienced cardiologists (Tab. 6, Fig. 4, Ref.

Cor triatriatum sinister (CTS) patrí k zriedkavým vrodeným srdcovým anomáliám. Zvyčajne je ľavá predsieň rozdelená membránou, ktorá bráni prítoku krvi cez pľúcne žily k mitrálnej chlopni a spôsobuje klinické príznaky ako u mitrálnej stenózy s pľúcnou kongesciou a pľúcnou hypertenziou. Najlepším spôsobom liečby je chirurgické odstránenie membrány, ale je možná aj katetrizačná intervencia. V našom príspevku uvádzame prípad pacienta s vrodenou anomáliou CTS, u ktorého sme úspešne, katetrizačne balónom dilatovali stenotický otvor v membráne s priaznivým hemodynamickým a klinickým výsledkom.

Defekt predsieňového septa predstavuje 5,9 % všetkých vrodených vývojových chýb srdca. Perkutánna implantácia okluzora je často používanou stratégiou liečby tejto malformácie. Šesťdesiatpäť ročná žena bola prijatá za účelom perkutánneho uzáveru defektu predsieňového septa. Počas zákroku došlo k dislokácii Amplatzerovho okluzora do pravej pľúcnej tepny. Vykonaný bol kardiochirurgický zákrok s explantáciou dislokovaného okluzora, uzáverom defektu a vytvorením aortokoronárneho bypassu s dobrým výsledkom. Dislokácia okluzora počas uzáveru defektu predsieňového septa je vzácna, ale život ohrozujúca komplikácia. Najčastejšie vyžaduje kardiochirurgickú intervenciu s explantáciou dislokovaného zariadenia a chirurgickým uzáverom defektu. Perkutánny uzáver defektu predsieňového septa je moderný a efektívny prístup liečby. Vzhľadom na možné riziká procedúry, možnosť okamžitej kardiochirurgickej intervencie pri vzniku komplikácií zvyšuje bezpečnosť tohto postupu.
