Here we report the case of a 31-year-old man admitted to our hospital with echocardiografic and Cardiac Magnetic Resonance signs of myocarditis complicated by ventricular tachycardia, initially resolved with direct current shock. After the recurrence of ventricular tachycardia the patient was submitted to electrophysiological study revealing a re-entrant circuit at the level of the medium segment of interventricular septum, successfully treated with transcatheter ablation. This case highlights how the presence of recurrent ventricular arrhythmias at the onset of acute myocarditis, suspected or proven, could be associated with a pre-existing arrhythmogenic substrate, therefore these patients should be submitted to electrophysiological study in order to rule out the presence of arrhythmogenic focuses that can be treated with transcatheter ablation...

Cardiovascular diseases are the leading cause of death in patients on haemodialysis. Cardiovascular mortality rate in these patients is approximately 9% per year, with the highest prevalence of left ventricular hypertrophy, ischemic heart disease and congestive heart failure being the most frequent cardiovascular complications. Risk factors for cardiac failure include hypertension, disturbed lipid metabolism, oxidative stress, microinflammation, hypoalbuminemia, anaemia, hyperhomocysteinemia, and increased concentration of asymmetric dimethylarginine, increased shunt blood flow and secondary hyperparathyroidism...

BACKGROUND: High dosage anthracyclines in pediatric patients with acute lymphoblastic leukemia (ALL) is associated with cardiotoxicity. However, data on the cardiac effects of lower cumulative doses of these drugs are not conclusive. The aim of this study was to assess the cardiac effects of low cumulative anthracycline doses in long-term survivors of ALL. PROCEDURE: Echocardiograms were performed on 62 long-term ALL survivors, without any overt or sub-clinical signs or symptoms of heart failure...

BACKGROUND/AIM: It is well known that patients with coronary artery disease and viable tissue as a guarantee of contractile recovery (CR), despite of decreasing ejection fraction (EF) and systolic dysfunction, could have benefit from surgical revascularization. Therefore, relationship between diastolic filling type and early postoperative recovery and complications need to be established. The aim of this study was to investigate the relation between different left ventricular (LV) diastolic filling types and CR in patients after surgical revascularization with differently preserved systolic function...

The aim of our study is to show the clinical potential of laparoscopic treatment of pericardial effusions. In spite of the small number of the patients we want to bring to attention the benefit of this mininvasive procedure. The laparoscopic fenestration is indicated when the pericardial effusion persists after unsuccessful medical treatment and when clinical and echocardiografic signs of tamponade develop (Ref 13).

The case-history occupies of a case of acute cardiac insufficiency in a patient at early postoperative period, who underwent a small surgical operation. Apparently the banal operation became the starting mechanism of life threatening cardiopulmonary insufficiency. Transthoracic echocardiografic diagnostic process not gave us the unambiguous response about a cause of that distressed state. The primary clinical consideration of the pulmonary embolization was not ambiguously acknowledged, though nor excluded. The clinical had to decided, whether the heparinization or the thrombolysing treatment was justified...

OBJECTIVE: Because of an increase of aortic root wall stress, prosthetic replacement of the ascending aorta might be a risk factor for the progressive increase of the aortic root dimension. Aim of the present study was to evaluate the aortic root diameter change and the progression of aortic valve regurgitation late after ascending aorta replacement for different ethiology. METHODS: Sixty-three late survivors after supracoronary ascending aortic replacement were evaluated...

Many studies have demonstrated that left ventricular hypertrophy is the most frequent cardiac alteration in patients on chronic hemodialysis. Autopsy studies have shown that hypertrophic hearts of uremic patients have peculiar characteristics, namely deposition of calcium salts, intermyocytic fibrosis, sometimes amyloid. None of the parameters obtainable from conventional echocardiografic images provides information on myocardial tissue structure. Analysis of "texture" originated as analysis of images sent by satellites for military or agricultural purposes and subsequently was applied to medicine for studying various organs like mainly and widely heart...

Systemic autoimmune diseases form a diverse group which includes: systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), scleroderma, dermato-polymyositis, Wegener's granulomatosis, Sjögren syndrome. Although multisystem involvement is the hallmark of these diseases, the heart seems to be less affected than other organ systems. The aim of the study was to study possible cardiac abnormalities in patients with documented systemic autoimmune diseases and to assess whether there was any relation between antiphospholipid, anti-dsDNA antibodies and myocardial dysfunction findings...

Ten patients with mitral stenosis underwent right and left heart catheterization. In order to assess the diastolic properties of these ventricles an hemodynamic-echocardiografic techniques was employed. Left ventricular pressure and an echocardiogram of the body of the left ventricle were simultaneously registered. Ventricular volume was determined using the minor axis (T) of the left ventricle measured form the echogram and assuming the long axis (L) from the L to T relationship observed in the left cineventriculography...

The preoperative diagnosis of an aneurysm of the posterior sinus of Valsalva with rupture into the right atrium was made by echocardiography in a 21-year-old patient. The M-mode echocardiography revealed the following findings: 1) a vibrating anomalous structure, continuous with the aortic wall, was present in the right atrium. The echo-producing mass was the wall of the aneurysm, which adhered to the septal leaflet of the tricuspid valve during early-to-mid systole and had an abrupt posterior motion in late systole...

REVIEW
W Urbaszek
The definition of the syndrome of heart failure is dependent upon clinical, pathophysiological and biochemical criteria. The interrelationship of the contributing factors in a given hemodynamic situation must be clarified by simple examination. "Heart failure" implies a condition with insufficient peripheral perfusion, despite a normal blood volume, a sufficient or increased filling pressure, and intact intrinsic and extrinsic compensatory mechanisms. The cardiac output varies with basic illness. The worsening vicious cycle between cardiac dysfunction and neuroendocrinal dysregulation in chronic heart failure has to be taken into consideration, especially while planning therapeutic strategy...

Echocardiographic studies were performed in 15 patients, aged 8 months to 20 years, with congenital valvular aortic stenosis confirmed by hemodynamic findings. Seven patients showed an anomalous pattern of the valvular echo in diastole (multiple valve echoes), seven exhibited an eccentric closure, and only in two patients the area was significantly reduced in systole. Therefore aortic valve diastolic pattern was more important than systolic appearance in the echocardiografic diagnosis of congenital valvular aortic stenosis...
