How Do Patients Understand Safety for Cardiac Implantable Devices? Importance of Postintervention Education.

Aim: This study was designed to assess the effect of patient education on the knowledge of safety and awareness about living with cardiac implantable electronic devices (CIEDs) within the context of phase I cardiac rehabilitation.

Methods: The study was conducted with 28 newly implanted CIED patients who were included in "education group (EG)". Patients were questioned with a survey about living with CIEDs and electromagnetic interference (EMI) before and 1 month after an extensive constructed interview.

Evaluation of heart rate variability in patients with coronary artery ectasia and coronary artery disease.

Objective: The present study compared heart rate variability (HRV) parameters in patients with coronary artery ectasia (CAE) and coronary artery disease (CAD).

Methods: The study population consisted of 60 consecutive patients with CAE (14 women; mean age 51.63±7.

Evaluating functional capacity, and mortality effects in the presence of atrial electromechanical conduction delay in patients with systolic heart failure.

Objective: Atrial functions are relatively suppressed in heart failure (HF). We aimed to investigate the associations of intra- and inter-atrial electromechanical conduction delay (EMCD) with functional class and mortality over a 12-month follow-up period.

Methods: The prospective study included 65 patients with systolic HF and 65 healthy subjects with normal sinus rhythm.

A rare complication: an attempt of retrieval of an aortic valve wrapped with pig tail catheter during transcatheter aortic valve implantation.

Transcatheter aortic valve implantation is preferred to treat high surgical risk patients with severe aort stenosis. Wrapping of a pig tail catheter with device struts during transcatheter aortic valve implantation is a very rare complication. In this report, we present the images and videos of an attempt of retrieval of an aortic valve wrapped with pig tail catheter during transcatheter aortic valve implantation in a 71-year-old man.

Effects of ivabradine therapy on heart failure biomarkers.

Background: Heart rate (HR) reduction is associated with improved outcomes in patients with heart failure (HF) and biomarkers can be a valuable diagnostic tool in HF management. The primary aim of our study was to evaluate the short-term (6 months) effect of ivabradine on N-terminal pro B-type natriuretic peptide (NT-proBNP), CA-125, and cystatin-C values in systolic HF outpatients, and secondary aim was to determine the relationship between baseline HR and the NT-proBNP, CA-125, cystatin-C, and clinical status variation with ivabradine therapy.

Methods: Ninety-eight patients (mean age: 65.

Sustained ventricular tachycardia in a patient with isolated non-compaction cardiomyopathy.

Isolated non-compaction of the left ventricular myocardium (INVM) was first described in 1984 as an unclassified cardiomyopathy, not being dilated, hypertrophic or restrictive. It is assumed to occur as a result of an arrest in endomyocardial morphogenesis during normal development of the heart. The disease is characterised by heart failure due to systolic and diastolic left ventricular (LV) dysfunction, systemic emboli and ventricular arrhythmias.

Atrial tachycardia treated by coil embolization of a giant coronary artery fistula.

Coronary artery fistulas are the second most frequently seen coronary anomaly following abnormalities of coronary artery origin and distribution. A coronary fistula is defined as a direct communication between a coronary artery and any cardiac chamber or vessel. Treatment options include percutaneous embolization and surgical intervention.

Left lateral free wall pathway ablation complicated by plaque rupture and acute occlusion of the left anterior descending coronary artery.

Radiofrequency (RF) ablation of accessory bypass tracts associated with the Wolff-Parkinson-White (WPW) syndrome has become the treatment of choice for many arrhythmias. Complications are unusual and acute coronary artery occlusion is very rare. We here present a 38-year-old male patient with an acute occlusion of proximal left anterior descending (LAD) coronary artery after RF ablation of a left free wall accessory pathway.

Disappearance of myocardial bridging of the left anterior descending coronary artery after inferior myocardial infarction.

Myocardial bridging (MB) is defined as the intramural course of a major epicardial coronary artery, and is mostly confined to the left ventricle and the left anterior descending coronary artery (LAD). MB is a common congenital abnormality of a coronary artery, and is usually thought to be a benign anatomical variant. Although rare, previous studies have reported that patients with MB may suffer from myocardial ischemia, myocardial infarction (MI), arrhythmias, and even sudden death.

Ventricular tachycardia-based long QT without hypocalcaemia after use of ibandronic acid.

Many drugs are known to cause lengthening of the QT interval. Ibandronic acid is a frequently used agent in the treatment of osteoporosis and is known to cause prolongation of the QT interval due to hypocalcaemia. However, no cases of long QT syndrome associated with ventricular tachycardia (VT) with a serum calcium level within the normal limits have been reported in the literature.

A case of multiple coronary microfistulas to the left ventricle and apical myocardial hypertrophy coexisting with stable angina.

A coronary artery fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common congenital anomaly that can affect coronary perfusion. However, coronary fistulas to one of the cardiac chambers and coexisting apical myocardial hypertophy are infrequent anomalies, and usually are found unexpectedly.

Coronary artery perforations: four different cases and a review.

Coronary artery perforation (CAP) is a rare but feared complication of percutaneous coronary intervention. With the advent of new devices and technologies, interventionalists attempt more complex lesions, including more calcified or tortuous vessels and chronic total occlusions, which increases the incidence of CAP. A short literature review, in addition to four cases of CAP, is presented in this report.

A good surgical option for ischemic mitral regurgitation in co-morbid patients: semicircular reduction annuloplasty.

Background: Ring annuloplasty is the standard treatment of ischemic mitral regurgitation (MR), however, it has been associated with some drawbacks. It abolishes normal annular dynamics and freezes the posterior leaflet. In the present study, we evaluated Paneth suture annuloplasty in chronic ischemic MR and both early and mid-term outcomes of the technique on a selected population.

Assessment of left ventricular systolic and diastolic function with conventional and tissue Doppler echocardiography imaging techniques in patients administered tyrosine kinase inhibitor.

Objectives: The aim of this study was to use echocardiographic techniques to determine the possible cardiotoxic effects of low molecular weight tyrosine-kinase inhibitors (TKI) in patients receiving the therapy for the first time.

Study Design: Thirty patients (17 females; 13 males; mean age 49±16; range 22 to 76 years) who met the exclusion criteria and were diagnosed as having malignancy were enrolled. All patients underwent conventional echocardiography and tissue Doppler imaging (TDI) prior to the treatment.

Appropriateness of the current guidelines on reperfusion treatment for patients applying to our hospital with ST-segment elevation acute myocardial infarction.

Objectives: This study investigated the appropriateness of treatment for patients admitted with ST-segment elevation myocardial infarction (STEMI) according to the current guidelines. We also aimed to determine in-patient and out-patient factors affecting optimal reperfusion therapy.

Study Design: The reperfusion therapy of 176 patients with STEMI was determined.

Serum chitotriosidase activity in acute coronary syndrome.

Aim: Inflammation is a critical participant in mediating all stages of cardiovascular disease. Studies related with chitotriosidase that was recently found to be relevant to arterial inflammation. In this study we evaluated activity of serum chitotriosidase in acute coronary syndrome patients and its relationship with cardiovascular events, cardiac enzymes and inflammatory indicators.

[The effect of nondipper blood pressure pattern on target organ damage in patients with metabolic syndrome].

Objectives: Both metabolic syndrome (MetS) and nondipping status (insufficient reduction in nocturnal blood pressure) have been linked with target organ damage. We evaluated the effect of nondipping status on target organ damage in subjects with MetS.

Study Design: Eighty-two patients diagnosed as having MetS were divided into two groups according to the findings of 24-hour ambulatory blood pressure monitoring as dipper (n=35, 19 women, 16 men; mean age 48.
