Factors that Determined a Positive Response to Resynchronization Therapy in Patients With Chronic Heart Failure and Cardiac Dyssynchrony. One Center Experience.

Aim: To evaluate the efficacy of cardiac resynchronization therapy (CRT) in patients with chronic heart failure (CHF) associated with cardiac dyssynchrony and to identify the factors that influence the CRT efficacy.

Material And Methods: This retrospective study included 155 patients after implantation of CRT devices. The CRT devices with a built-in cardioverter-defibrillator (CRT-D) and without it (CRT-P) were implanted in 139 (89.

VisQA: X-raying Vision and Language Reasoning in Transformers.

Visual Question Answering systems target answering open-ended textual questions given input images. They are a testbed for learning high-level reasoning with a primary use in HCI, for instance assistance for the visually impaired. Recent research has shown that state-of-the-art models tend to produce answers exploiting biases and shortcuts in the training data, and sometimes do not even look at the input image, instead of performing the required reasoning steps.

The Necessity of an ICD-Therapy in Patients with Indications for Primary Prevention of Sudden Cardiac Death. One Center Experience.

Aim      Analysis of responses of cardioverter-defibrillators implanted in patients with cardiomyopathies (CMPs) of various origins and a high risk of sudden cardiac death (SCD) to assess the effectiveness of a modern strategy for primary prevention of SCD.Material and methods  In the Federal Center for High Medical Technologies in Kaliningrad from 2014 through 2018, implantable cardioverter-defibrillators (ICD) and cardiac resynchronization therapy defibrillators (CRT-D) were installed in 165 patients. Major indications for device implantation in these patients included left ventricular (LV) systolic dysfunction with ejection fraction (EF) ≤35 %; chronic heart failure (CHF) consistent with the New York Heart Association (NYHA) functional class (FC) II-III (IV for CRT-D) without previous episodes of life-threatening ventricular arrhythmias, circulatory arrest and resuscitation, which was consistent with the current international strategy for primary prevention of SCD.

[Angiographic Results After Coronary Artery Bypass Grafting].

Unlabelled: The main place among cardiovascular diseases takes coronary heart disease. The number of coronary artery bypass surgery increases every year. The large number of coronary artery bypass grafting (CABG) performed worldwide.

[Experience of Treatment of Spontaneous Rupture of Left Ventricular Posterior Wall After Mitral Valve Replacement].

Spontaneous rupture of the left ventricular posterior wall after mitral valve replacement is a severe complication and is associated with high mortality rate. This complication was first described in 1967 by Roberts and Morrow, which describe the results of autopsy of two patients. In leading clinics around the world left ventricular wall ruptures after mitral valve replacement account for up to 20% of causes of hospital mortality.

First experience of cardiac autotransplantation for giant left atrium treatment.

Giant left atrium is a pathology that causes a lot of different complications, therefore it is very important to perform volume reduction. In some cases left atrium volume reaches a huge size. There are a lot of different methods for left atrium reduction: from wall plication, multicomponent resection followed by restoration integrity of wall to autotransplantation.
