Article Synopsis
  • * The study involved 597 patients, finding a low 30-day mortality rate of 0.7%, significant improvements in heart function, and good long-term survival rates at 1, 5, and 10 years.
  • * Results indicate that both single and repeated ASA procedures had similar outcomes in terms of survival and heart function over time, suggesting effectiveness in the treatment of HCM.

Conventional radial access in endovascular surgery has certain limitations, primarily associated with the presence of local complications and radial artery occlusion. Over the past 7 years, distal radial access has exploded into all areas of endovascular procedures, from interventional cardiology to vascular surgery and interventional oncology. However, puncture of the distal radial artery has its own nuances and features: a learning curve, the use of ultrasound navigation in the initial stages of mastering the access, limitations in patients with acute conditions (acute coronary syndrome and stroke).

Electrocardiography occupies a special place among a significant list of other methods for diagnosing the pathology of the cardiovascular system of athletes. Often its results differ significantly from those in the general population, being a consequence of the adaptation of the heart to economical functioning at rest and super-intensive work in training and competitions. This review focuses on the features of the "athlete's electrocardiogram (ECG).

The cardiovascular system experiences the greatest overload, morphological and functional changes inelite sport, which in a number of athletes undergoes nonadaptive (pathological) remodeling both functional and morphological. The latter is characterized by certain objective features, including echocardiography indicators, which occupies a special place in sports cardiology. Structural and functional changes beyond the generally accepted norm (pronounced cardiac hypertrophy or dilatation, high arterial hypertension) can be associated with systolic or diastolic myocardial dysfunction and impaired electrical properties, some of which are predictors of severe complications up to sudden cardiac death and pose a serious problem regarding the admission of athletes to training and competition.

Objective: There is a lack of data regarding the long-term clinical efficacy of the kissing balloon inflation (KBI) after provisional stenting of coronary bifurcation lesions. The aim of this study was to analyze the impact of KBI on long-term clinical outcomes in patients undergoing provisional stenting for the coronary bifurcation lesions in a large real-world population.

Methods: A total of 873 patients who underwent percutaneous coronary interventions (PCI) with provisional stenting and had clinical follow up were analyzed.

Article Synopsis
  • Atrioventricular block is a common complication following alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy, leading to some requiring a permanent pacemaker (PPM).
  • In a study involving 1,814 patients using the Euro-ASA registry, 9.4% underwent PPM implantation within 30 days after the procedure, with a follow-up averaging 4 years.
  • Long-term outcomes revealed that while survival and functional class were similar between groups, those with PPM had a lower left ventricular outflow gradient and lower likelihood of needing further interventions.

Article Synopsis
  • A new risk score called ASA-SCARRE was developed to assess the risk of sudden cardiac arrest in patients with hypertrophic obstructive cardiomyopathy after alcohol septal ablation.
  • The study analyzed over 1,800 patients and found that independent predictors of sudden cardiac arrest included septum thickness and left ventricular outflow tract gradient.
  • The ASA-SCARRE scores ranged from 0 to 2 based on these two factors, providing a simple method to predict long-term risk of cardiac events post-treatment.

Background: The aim of this study was to evaluate short- and long-term outcomes related to dose of alcohol administered during alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy (HOCM). Current guidelines recommend using 1-3 mL of alcohol administered in the target septal perforator artery, but this recommendation is based more on practical experience of interventionalists rather than on systematic evidence.

Methods: We included 1448 patients and used propensity score to match patients who received a low-dose (1.

Objectives: The objective of this research was to assess the long-term results of alcohol septal ablation in patients with hypertrophic obstructive cardiomyopathy (HOCM), with all of them receiving a standard 3 mL ethanol dose.

Background: Generally, ethanol (0.5-3 mL) is infused depending on a septal artery width or interventricular septum (IVS) thickness during alcohol septal ablation.

Objective: The current guidelines suggest alcohol septal ablation (ASA) is less effective in hypertrophic obstructive cardiomyopathy (HOCM) patients with severe left ventricular hypertrophy, despite acknowledging that systematic data are lacking. Therefore, we analysed patients in the Euro-ASA registry to test this statement.

Methods: We compared the short-term and long-term outcomes of patients with basal interventricular septum (IVS) thickness <30 mm Hg to those with ≥30 mm Hg treated using ASA in nine European centres.

Aims: Based on European guidelines, alcohol septal ablation (ASA) for hypertrophic obstructive cardiomyopathy (HOCM) is indicated only in patients with interventricular septum (IVS) thickness >16 mm. The aim of this study was to evaluate the short- and long-term outcomes in ASA patients with mild hypertrophy (IVS ≤ 16 mm).

Methods And Results: We retrospectively evaluated 1505 consecutive ASA patients and used propensity score to match 172 pairs (344 patients) in groups IVS ≤ 16 mm or IVS > 16 mm.

This study looks at 10-year follow-up outcomes of alcohol septal ablation in patients with obstructive hypertrophic cardiomyopathy. Between 2000 and 2008, 40 patients with obstructive hypertrophic cardiomyopathy (27 males, 13 females) underwent alcohol septal ablation. The median follow-up period was 123 (2-179) months.
