Coronary-cameral fistulas, though mostly regarded as congenital entities, have also been encountered as complications of major traumas and percutaneous coronary interventions (PCIs).1 On the other hand, interventricular septal (IVS) hematoma might potentially arise mostly during retrograde chronic total occlusion (CTO) interventions and has a benign course in this context.2 Herein, we describe a challenging PCI complication (and its management strategy) presenting with IVS hematoma, right ventricular fistula, and right ventricular outflow tract (RVOT) obstruction due to a misimplanted coronary stent in the septal perforating artery (SPA).

As fístulas coronário-camerais, embora consideradas em sua maioria como entidades congênitas, também têm sido encontradas como complicações de grandes traumas e intervenções coronárias percutâneas (ICPs).1 Por outro lado, o hematoma do septo interventricular (SIV) pode potencialmente surgir principalmente durante intervenções de oclusão total crônica retrógrada (OTC) e tem um curso benigno nesse contexto.2 Aqui, descrevemos uma complicação desafiadora da ICP (e sua estratégia de manejo) apresentando hematoma do SIV, fístula ventricular direita e obstrução da via de saída do ventrículo direito (VSVD) devido a um stent coronário mal implantado na artéria septal perfurante (ASP).

Cancer Therapy-Related Pulmonary Hypertension: A Review of Mechanisms and Implications for Clinical Practice.

Cancer therapy-related pulmonary hypertension is a rare yet potentially fatal cardiotoxicity. However, it is a reversible cause of pulmonary hypertension if detected in its early stages. Cancer therapy-related pulmonary hypertension has been encountered in patients using tyrosine kinase inhibitors, particularly dasatinib. However, it is also well known that many agents used in cancer treatment such as alkylating agents, proteasome inhibitors, thoracic radiation exposure, and immune checkpoint inhibitors are particularly associated with pulmonary hypertension evolution. In case that history, symptoms, and clinical findings suggest a potential cancer therapy-related pulmonary hypertension, echocardiography is considered as the initial tool to detect pulmonary hypertension. If the possibility of pulmonary hypertension is high based on echocardiographic data, cancer treatment, as the initial step, should be discontinued due to its potential risks and other causes for pulmonary hypertension should be investigated thoroughly. Right heart catheterization should be the next step to establish the final diagnosis, and medical management, where appropriate, should be started without delay in these patients according to their pulmonary hypertension subgroup. There exists limited information regarding the diagnostic and management strategies of cancer therapy-related pulmonary hypertension in the current guidelines. In this review article, we aim to present current literature data on the mechanisms and management of cancer therapy-related pulmonary hypertension along with its follow-up algorithm in the setting of cardio-oncology practice.

Systemic Immune-Inflammation Index: A Novel Predictor of Coronary Thrombus Burden in Patients with Non-ST Acute Coronary Syndrome.

Background and Objectives: Excessive coronary thrombus burden is known to cause an increase in mortality and major adverse cardiac events (MACEs) in NSTE-ACS (non-ST acute coronary syndrome) patients. We investigated the association between the systemic immune-inflammation index (SII) and coronary thrombus burden in patients with non-ST segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography and percutaneous coronary intervention (PCI). Materials and Methods: A total of 389 patients with the diagnosis of NSTEMI participated in our study. Coronary thrombus burden was classified in the TIMI (thrombolysis in myocardial infarction) thrombus grade scale and patients were divided into two groups: a TIMI thrombus grade 0-1 group (n = 209, 157 males) and a TIMI thrombus grade 2-6 group (n = 180, 118 males). Demographics, angiographic lesion images, coronary thrombus burden, clinical risk factors, laboratory parameters, and SII score were compared between the two groups. Results: The high thrombus burden patient group had a higher neutrophil count, WBC count, platelet count, and systemic immune-inflammation index (SII) (p < 0.001). The receiver operating characteristic (ROC) curve analysis showed that at a cutoff of 1103, the value of SII manifested 74.4% sensitivity and 74.6% specificity for detecting a high coronary thrombus burden. Conclusions: Our study showed that the SII levels at hospital admission were independently associated with high coronary thrombus with NSTEMI.

The etiology and age-related properties of patients with delirium in coronary intensive care unit and its effects on inhospital and follow up prognosis.

Background and purpose: Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. Methods: This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. Results: A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Conclusion: Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

The Effect of Thyroid Stimulating Hormone Level Within the Reference Range on In-Hospital and Short-Term Prognosis in Acute Coronary Syndrome Patients.

Background and objectives: Despite being within the normal reference range, changes in thyroid stimulating hormone (TSH) levels have negative effects on the cardiovascular system. The majority of patients admitted to hospital with acute coronary syndrome (ACS) are euthyroid. The aim of this study was to investigate the effect of TSH level on the prognosis of in-hospital and follow-up periods of euthyroid ACS patients. Materials and Methods: A total of 629 patients with acute coronary syndrome without thyroid dysfunction were included in the study. TSH levels of patients were 0.3-5.33 uIU/mL. Patients were divided into three TSH tertiles: TSH level between (1) 0.3 uIU/mL and <0.90 uIU/mL (n = 209), (2) 0.90 uIU/mL and <1.60 uIU/mL (n = 210), and (3) 1.60 uIU/mL and 5.33 uIU/mL (n = 210). Demographic, clinical laboratory, and angiographic characteristics were compared between groups in terms of in-hospital and follow-up prognosis. Results: Mean age was 63.42 ± 12.5, and 73.9% were male. There was significant difference between tertiles in terms of TSH level at admission (p < 0.001), the severity of coronary artery disease (p = 0.024), in-hospital mortality (p < 0.001), in-hospital major hemorrhage (p = 0.005), total adverse clinical event (p = 0.03), follow-up mortality (p = 0.022), and total mortality (p < 0.001). In multivariate logistic regression analysis, the high-normal TSH tertile was found to be cumulative mortality increasing factor (OR = 6.307, 95%; CI: 1.769-22.480; p = 0.005) during the 6-month follow-up period after hospitalization and discharge. Conclusions: High-normal TSH tertile during hospital admission in euthyroid ACS patients is an independent predictor of total mortality during the 6-month follow-up period after hospitalization and discharge.
