Atrial and ventricular arrhythmia predictors with electrocardiographic parameters in myocardial infarction with non-obstructive coronary artery disease (MINOCA).

Background: The clinical importance and recognition of myocardial infarction with non-obstructive coronary artery disease (MINOCA) is increasing. Nevertheless, no studies are investigating the risk of atrial fibrillation and ventricular arrhythmia in MINOCA patients. This study aimed to determine the risk of arrhythmia with electrocardiographic predictors in MINOCA patients.

Prognostic Value of Nutritional Indexes in Evaluating the 1-Year Results after Implantation of the Carillon Mitral Contour System.

Background: The prognostic importance of nutritional indexes has been shown in some diseases. We aimed to examine the prognostic value of these indexes in patients implanted with the Carillon Mitral Contour System (CMCS).

Methods: Fifty-four patients who underwent successful CMCS implantation were evaluated.

Unrecognized indication for aortic valve neocuspidization: Patient with warfarin-induced Stevens-Johnson syndrome and toxic epidermal necrolysis.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe disorders, characterized by necrosis and epidermal detachment. Most important known acquired etiological factor is medications. Warfarin is one of the most common medications of cardiac valve surgery, which may rarely cause SJS or TEN.

Percutaneous Mitral Valve Repair with the MitraClip System in Mitral Regurgitation Due to Mitral Annular Calcification.

Percutaneous valve repair with the MitraClip represents a new and promising therapeutic option for patients with severe mitral regurgitation (MR). Mitral valve prolapse and flail leaflet are two major causes of degenerative MR in patients who underwent the MitraClip procedure. Mitral annular calcification (MAC) is also a less-frequent cause of degenerative MR.

Concurrent Transcatheter Aortic Valve Implantation and Percutaneous Transvenous Mitral Commissurotomy for Totally Percutaneous Treatment of Combined Severe Rheumatic Aortic and Mitral Stenosis.

Transcatheter aortic valve implantation (TAVI) is a new promising therapeutic option for patients with symptomatic severe calcific aortic valve stenosis (AS) who are inoperable or at high risk for conventional cardiac surgery. Percutaneous transvenous mitral commissurotomy (PTMC) is performed routinely in patients with severe mitral stenosis (MS) having a favorable anatomy. Although concurrent TAVI and PTMC is a theoretically possible approach in the treatment of patients with severe AS and MS who are unsuitable for conventional surgery, no cases have yet been reported in which this combined technique is used.

First experience with the jailed pressure wire technique in the provisional side branch stenting of coronary bifurcation lesions.

Aims: The provisional strategy (PS) is an accepted modality of treatment in coronary bifurcation interventions, though, after main vessel (MV) stenting, the assessment of the side branch (SB) becomes more difficult. In bifurcation interventions, the major advantage of fractional flow reserve (FFR) is the avoidance of the need for SB intervention. However, SB access with a pressure wire after MV stenting may be difficult, sometimes impossible.

Comparison of a safety strategy using transradial access and dual-axis rotational coronary angiography with transfemoral access and standard coronary angiography.

Objectives: We sought to investigate the radiation exposure and contrast utilization associated with using a strategy of transradial access and rotational angiography (radial-DARCA) compared to the traditional approach of transfemoral access and standard angiography (femoral-SA).

Background: There is an increased focus on optimizing patient safety during cardiac catheterization procedures. Professional guidelines have highlighted physician responsibility to minimize radiation doses and contrast volume.

Transcatheter aortic valve implantation with a CoreValve bioprosthesis in a 57-year-old man.

Transcatheter aortic valve implantation (TAVI) is a promising new technology which is typically used to treat elderly patients with severe aortic stenosis who cannot undergo surgical aortic valve replacement due to high risk factors. This procedure may also be a therapeutic option in particular relatively young cases with severe symptomatic aortic stenosis who are unsuitable candidates for surgery. Clinical experience with TAVI in these patients is very limited due to concerns regarding long-term valve durability.

Successful percutaneous mitral valve repair with the MitraClip system of acute mitral regurgitation due to papillary muscle rupture as complication of acute myocardial infarction.

Percutaneous mitral valve repair with the MitraClip is a new promising therapeutic option for symptomatic severe mitral regurgitation (MR). Acute myocardial infarction (MI) is a well recognized cause of papillary muscle rupture (PMR). If PMR is untreated, the prognosis is poor and the mortality could be as high as 80% during the first week of post MI.

The Correlation between Infarct Size and the QRS Axis Change after Thrombolytic Therapy in ST Elevation Acute Myocardial Infarction.

Objective: Electrocardiography (ECG) may be a practical guiding tool for prognostic infarct sizing in ST elevation acute myocardial infarction (STEAMI). In this study, we sought to find a relation between the infarct size and the change in the QRS axis after thrombolytic therapy.

Materials And Methods: Patients with STEAMI who received thrombolytic therapy were selected retrospectively.

Effect of primary percutaneous coronary intervention on myocardial repolarization.

Objective: We aimed to investigate the effect of coronary perfusion on QT interval dispersion in patients with acute myocardial infarction (MI).

Methods: Seventy-seven consecutive patients who had undergone primary percutaneous coronary intervention (PCI) for a first ST segment elevation MI during the first 12 h of symptom onset were included in the study. After achievement of thrombolysis in MI (TIMI) 3 flow of the infarct-related artery, corrected TIMI frame count (cTFC) and TIMI myocardial perfusion grade (TMPG) were measured.

Assessment of coronary veins in patients with isolated coronary artery ectasia by antegrade coronary venous angiography.

Background: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. The most common cause of CAE is atherosclerosis but other possible etiologies include congenital abnormalities and inflammatory and connective tissue disease. Earlier studies have documented the association of CAE with the presence of aneurysms in other vascular beds.

Effect of autonomic dysfunction on p-wave dispersion in patients with chronic spinal cord injury.

Objective: To provide information about the effect of autonomic dysfunction on P-wave dispersion, as a predictor of atrial fibrillation, in patients with spinal cord injury.

Design: Thirty patients with chronic traumatic spinal cord injury and 27 healthy controls were included in this study. The initial assessment of the patients included routine physical examination and evaluation of 12-lead electrocardiography.

Association between admission mean platelet volume and coronary patency after thrombolytic therapy for acute myocardial infarction.

Objectives: High levels of mean platelet volume (MPV) have been shown to be a predictor of poor clinical outcome among survivors of myocardial infarction. We evaluated the association between admission MPV and infarct-related artery (IRA) patency in patients treated with thrombolytic therapy for acute myocardial infarction (AMI).

Study Design: We retrospectively evaluated 133 consecutive patients with ST-elevation AMI, who received thrombolytic therapy within 12 hours of chest pain.

Penetrating atherosclerotic aortic ulcer mimicking acute inferior myocardial infarction.

Penetrating atherosclerotic ulcers (PAU), aortic dissection, and intramural hematoma are the three most important diseases involving the aorta which are classified as acute aortic syndromes. Penetrating atherosclerotic aortic ulceration is characterized by ulceration of atheromatous plaque disrupting the internal elastic lamina. These aortic ulcers may penetrate through the media to cause aortic pseudoaneurysms or less often through the adventitia to cause transmural aortic rupture.

Left atrial appendage aneurysm secondary to eccentric severe ischemic mitral regurgitation.

Dilatation primarily confined to the left atrial appendage (LAA) is an unusual condition in nonrheumatic mitral valve disease. We report a case of 56-year-old male with a giant LAA secondary to ischemic severe mitral regurgitation without significant dilatation of the left atrial main chamber. The mitral regurgitation jet was directed toward the LAA, which we thought as the cause of disproportionate LAA enlargement.

P-wave duration and dispersion in patients with metabolic syndrome.

Background: Metabolic syndrome (MS) has been reported to be associated with an increased risk of atrial fibrillation (AF). The aim of this study was to investigate P-wave dispersion (PWD) in patients with MS.

Methods: The study population included 66 patients with MS (21 men, 45 women; mean age, 49.

Impact of metabolic syndrome on coronary patency after thrombolytic therapy for acute myocardial infarction.

Objectives: The metabolic syndrome (MS) is highly prevalent in patients with acute myocardial infarction. It has been shown that MS is associated with poor in-hospital outcome and long-term survival in patients with acute myocardial infarction. We aimed to investigate the effect of MS on the infarct-related artery patency in patients treated with thrombolytic therapy for acute myocardial infarction.

Isolated pulmonic valve endocarditis in an adult patient with ventricular septal defect and infundibular pulmonary stenosis.

Ventricular septal defect associated with infundibular pulmonary stenosis is a relatively uncommon congenital cardiac defect. We report the first case of a patient with perimembranous small ventricular septal defect and infundibular stenosis suffered from pulmonary valve endocarditis and septic pulmonary embolism.

Comparison of major coronary risk factors in female and male patients with premature coronary artery disease.

Objective: The present study was designed to analyse and compare the major coronary risk factors of female and male patients with premature coronary artery disease (CAD) aged < or = 45 years.

Methods: We evaluated 4613 consecutive patients who underwent coronary angiography at our institution; 572 symptomatic patients (489 men and 83 women) diagnosed as having premature CAD (age < or = 45 years) were included in our analysis. For each patient, the presence of major coronary risk factors such as family history of CAD, hypercholesterolaemia, diabetes mellitus, hypertension and cigarette smoking were recorded.

The impact of metabolic syndrome on left ventricular function: evaluated by using the index of myocardial performance.

Aim: To evaluate the impact of metabolic syndrome on global left ventricular function by using the index of myocardial performance.

Methods: The study population included 106 patients with metabolic syndrome (66 male, 40 female, mean age =54+/-11 years) and 106 control subjects without metabolic syndrome (71 male, 35 female, mean age=53+/-10). The diagnosis of metabolic syndrome was based on The National Cholesterol Education Program Adult Treatment Panel III criteria.

Increased platelet activity in patients with isolated coronary artery ectasia.

Background: The common coexistence with coronary artery disease has led to the suggestion that coronary artery ectasia (CAE) is a variant of coronary artery disease. The mechanisms, however, responsible for CAE formation during the atherosclerotic process and the exact clinical significance are not well known. In this study, we aimed to investigate platelet activity in patients with isolated CAE by using specific markers of platelet activation as P-selectin, beta-thromboglobulin (beta-TG) and platelet factor 4 (PF4).
