Recurrent pulmonary microemboli secondary to primary cardiac hydatidosis.

Primary cardiac hydatid cysts are rarely diagnosed and seldom rupture to lungs via pulmonary vein resulting in multifocal cystic lesions. We report a rare instance of an interventricular hydatid cyst. A 19-year-old patient was admitted with dyspnea and multiple homogenous opacities with different sizes in his chest X-ray and contrast enhanced thorax computed tomography.

Current role of laser angioplasty of restenotic coronary stents.

Treatment of in-stent restenosis (ISR) with conventional percutaneous transluminal coronary angioplasty (PTCA) causes significant recurrent neointimal tissue growth in 30-85%. Therefore, laser ablation of intrastent neointimal hyperplasia before balloon dilation can be an attractive alternative. However, the long-term outcomes of such treatment have not been studied thoroughly enough.

[Rheolytic thrombectomy with AngioJet catheter during transluminal coronary revascularization in patients with acute myocardial infarction].

Background: Although balloon angioplasty and stenting are effective in the treatment of acute myocardial infarction (M1), reduced coronary flow and distal embolization frequently complicate interventions when thrombus is present. Adjunctive treatment with mechanical thrombectomy devices was suggested to reduce these complications.

Methods: We evaluated immediate angiographic, in-hospital and 30-day follow-up clinical outcomes of 185 patients with acute MI and angiographically evident thrombus who were treated with AngioJet rheolytic thrombectomy followed by immediate definitive treatment.

[Effectiveness of excimer laser coronary angioplasty in treatment of patients with in-stent restenosis].

In-stent restenosis (ISR), when treated with balloon angioplasty (PTCA) alone, has an angiographic recurrence rate of 30-85%. Ablating the hypertrophic neointimal tissue prior to PTCA is an attractive alternative, however late outcomes of such treatment have not been fully determined. This multicenter case control study assessed angiographic and clinical outcomes of 137 consecutive procedures in 125 patients treated for ISR with either PTCA alone (n = 58) or excimer laser assisted coronary angioplasty (ELCA, n = 67).

[Immediate and long-term outcomes after "Ephesos" coronary stent implantation in patients with stable or unstable angina].

Aim: An open non-randomized trial was initiated to assess clinical and angiographic results of using the coronary stent "Ephesos" in 457 patients with stable or unstable angina pectoris and native coronary affections.

Material And Methods: 268 stents have been implanted in 231 patients with stable angina (SA) and 271 stents--in 226 patients with unstable angina (UA). 46% lesions were complicated.

The relationship of ST segment elevation shape with preserved myocardium and signal-averaged electrocardiography in acute anterior myocardial infarction.

Although a relation between magnitude of ST segment elevation and myocardial damage has been shown in the early period of acute myocardial infarction (AMI), such a relation between the shape of the ST segment elevation, myocardial damage, and the clinical course remains obscure. For this purpose 62 first anterior AMI patients admitted in the first 6h were enrolled for the study. On the basis of precordial V3 derivation prior to thrombolytic therapy, the shape of the ST elevation was separated into three groups: concave (n = 26), straight (n = 24), or convex types (n = 12).

[The relation between infarction localization and late potentials].

Objective: There are controversies about the relation between infarction localization and late potentials (LP) following acute myocardial infarction (AMI). To evaluate this issue 124 consecutive patients with first Q-wave AMI fulfilling the inclusion criteria were enrolled in this signal--averaged ECG (SAECG) study.

Methods: The patients were divided into three groups according to infarction localization: anterior (Group I n = 62; 50%), inferior (Group II: n = 42; 34%) and both inferior and right ventricular (RV) involvement (Group III n = 20; 16%).

A complicated case of pericardial hydatid cyst manifesting as constrictive pericarditis.

Although cardiac involvement with hydatid cyst is quite rare as a major complication, constrictive pericarditis is even less common. A 55-year-old man is presented in whom a hydatid cyst located in the right cardiophrenic angle anterior to the right ventricle ruptured into the pericardial sac, resulting in constrictive pericarditis.

Relation between QT dispersion and ventricular arrhythmias in uncomplicated isolated mitral valve prolapse.

Complications of mitral valve prolapse (MVP), among which serious ventricular arrhythmia and sudden death are of major importance, affect many individuals due to the high incidence of MVP itself in the community despite the actual low incidence of these complications. The present study investigated the incidence and distribution of ventricular arrhythmias according to their severity and relationship with the QT interval and dispersion of repolarization in uncomplicated isolated MVP (IMVP) cases. Fifty-eight uncomplicated IMVP patients, 33 patients with accompanying tricuspid valve prolapse (TVP), to compare its relationship with ventricular arrhythmia, and 60 age- and sex-matched control subjects were enrolled in the study.
