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.

Fragmented QRS is a marker of mortality in patients with severe COVID-19: A retrospective observational study.

Objective: In this study, we aimed to investigate the association of fragmented QRS (f-QRS) with in-hospital death in patients with severe novel coronavirus disease 2019 (COVID-19).

Methods: This was a retrospective and observational study. A total of 201 consecutive patients with severe COVID-19 were enrolled.

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.

Type 1 Kounis Syndrome Induced by Inactivated SARS-COV-2 Vaccine.

Background Vaccination is the most important way out of the novel coronavirus disease 2019 (COVID-19) pandemic. Vaccination practices have started in different countries for community immunity. In this process, health authorities in different countries have preferred different type of COVID-19 vaccines.

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.

Hydroxychloroquine/azithromycin treatment, QT interval and ventricular arrhythmias in hospitalised patients with COVID-19.

Background: Hydroxychloroquine (HCQ) and azithromycin (AZM) are widely used in off-label treatment of novel coronavirus disease (COVID-19). However, cardiac safety of these drugs is still controversial in COVID-19. Therefore, we aimed to evaluate association of HCQ or HCQ + AZM treatment regimens, corrected QT (QTc) interval and malignant ventricular arrhythmias in hospitalized patients.

The effect of transcatheter aortic valve implantation on mean platelet volume.

Background/aim: Transcatheter aortic valve implantation (TAVI) is an innovative approach to the treatment of aortic stenosis (AS) as an alternative to surgery in high-risk patients. Mean platelet volume (MPV) is considered an indicator of endothelial dysfunction, platelet function, and activation. In this study, we aimed to investigate MPV changes in patients undergoing TAVI.

Prosthetic valve endocarditis 7 months after transcatheter aortic valve implantation diagnosed with 3D TEE.

Transcatheter aortic valve implantation (TAVI) was introduced as an alternative treatment for patients with severe symptomatic aortic stenosis for whom surgery would be high-risk. Prosthetic aortic valve endocarditis is a serious complication of surgical AVR (SAVR) with high morbidity and mortality. According to recent cases, post-TAVI prosthetic valve endocarditis (PVE) seems to occur very rarely.

Transcatheter aortic valve implantation in the presence of hematologic malignancies.

Objective: Cardiac surgery may be performed in patients with hematologic disorders, but carries an increased risk of morbidity. This series describes an experience of transcatheter aortic valve implantation (TAVI) in patients with hematologic malignancies, and highlights the technical considerations to be kept in mind.

Methods: Between June 2011 and April 2014, 133 consecutive high-risk patients with symptomatic severe aortic stenosis were treated with TAVI at our centre.

Successful transcatheter aortic valve implantation in a Hodgkin lymphoma patient with severe aortic stenosis.

Transcatheter aortic valve implantation (TAVI) has emerged as an acceptable treatment modality for patients with severe aortic stenosis (AS) who are deemed unsuitable for conventional surgical aortic valve replacement. TAVI not only provides the treatment of AS, but also makes some other diseases treatable by relieving hemodynamic distress resulting from AS. In this case report, we presented a 74-year-old patient with Hodgkin's lymphoma (HL) that had been left untreated due to the development of acute pulmonary edema caused by severe degenerative AS during chemotherapy.

Assessment of the relationship between aortic stiffness and left ventricular functions with echocardiography in patients with Sjögren's syndrome.

Background And Aim: Capable of multi-organ involvement in Sjogren's syndrome (SS), cardiac findings of pulmonary effusion, left ventricular diastolic dysfunction and pulmonary hypertension are seen in patients with SS. Aortic stiffness (AS) reflects the mechanical tension and elasticity of the aorta. In this study, our aim is to determine if there is any differences in AS and left ventricular function between patients diagnosed as SS and healthy control groups.
