Multi-Center Experience of Coronary Artery Perforation During Percutaneous Coronary Intervention: Clinical and Angiographic Characteristics, Management, and Outcomes Between 2010 and 2020.

Background: Coronary artery perforations are one of the most feared, rare, and catastrophic complication of percutaneous coronary intervention. Despite the remarkable increase in coronary angiography and percutaneous coronary intervention, there is no large database that collects coronary artery perforation for the Turkish population. Our study aimed to report our experience over a 10-year period for clinical and angiographic characteristics, management strategies, and outcomes of coronary artery perforation during the percutaneous coronary intervention at different cardiology departments in Turkey.

Frontal QRS/T angle can predict mortality in COVID-19 patients.

Aims: The frontal QRS-T (fQRS) angle has been investigated in the general population, including healthy people and patients with heart failure. The fQRS angle can predict mortality due to myocarditis, ischaemic and non-ischaemic cardiomyopathies, idiopathic dilated cardiomyopathy, and chronic heart failure in the general population. Moreover, no studies to date have investigated fQRS angle in coronavirus disease 2019 (COVID-19) patients.

Prognostic value of C-reactive protein/albumin ratio in hypertensive COVID-19 patients.

Objectives: The aim of this study was to investigate the relationship between the C-reactive protein/albumin ratio and the prognosis of hypertensive COVID-19 patients.

Methods: It was designed as a single center retrospective study. PCR positive COVID-19 patients who were followed up in the intensive care unit (ICU) and received antihypertensive treatment were included in the study.

Comparison of Framingham risk score and atherogenic indices as a predictor of atherosclerosis in patients with myocardial bridge in left anterior descending artery.

Background: Myocardial bridge (MB) is generally considered as a benign condition, but it may trigger atherosclerosis, especially in the adjacent proximal coronary artery segment. In this study, we aimed to investigate whether the Framingham risk score (FRS) or atherogenic indices are risk factors for coronary atherosclerosis in patients with MB in the left anterior descending coronary artery (LAD).

Methods: We performed a retrospective study evaluating 155 patients who have MB in LAD.

CHA2DS2-VASc score and modified CHA2DS2-VASc score can predict mortality and intensive care unit hospitalization in COVID-19 patients.

In this study, we investigated whether the CHA2DS2-VASc score could be used to estimate the need for hospitalization in the intensive care unit (ICU), the length of stay in the ICU, and mortality in patients with COVID-19. Patients admitted to Merkezefendi State Hospital because of COVID-19 diagnosis confirmed by RNA detection of virus by using polymerase chain reaction between March 24, 2020 and July 6, 2020, were screened retrospectively. The CHA2DS2-VASc and modified CHA2DS2-VASc score of all patients was calculated.

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.

MicroRNA -143 and -223 in obesity.

Background: Obesity alters endocrine and metabolic functions of adipose tissue and has been recognized as a chronic inflammatory disease, which in turn may contribute to the development of insulin resistance, type 2 diabetes, obesity-associated vasculopathy and cardiovascular disease. The pathogenesis of obesity involves many regulatory pathways including transcriptional regulatory networks, including microRNAs.

Methods: A total of 83 patients were included in the study.

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.

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.
