BACKGROUND/AIM: Sacubitril/valsartan (SV), a novel pharmacological class of angiotensin receptor neprilysin inhibitors, is effective in treating heart failure (HF) by inhibiting the degradation of natriuretic peptides and the renin-angiotensin-aldosterone system. However, no studies have observed the long-term effects of SV on patients with HF and preserved left ventricular ejection fraction (LVEF) undergoing hemodialysis (HD) over a long period. PATIENTS AND METHODS: This single-center retrospective study of 21 months duration involved consecutive patients with HF and preserved LVEF undergoing HD, who received 50-200 mg/day...

OBJECTIVE: Segmentectomy is becoming the standard of care for small, peripheral non-small cell lung cancer. To improve perioperative management in this population, this study aims to identify factors influencing hospital length of stay after segmentectomy. METHODS: Patients who underwent segmentectomy for any indication between 01/2018-05/2023 were identified using a prospectively maintained institutional database. Multivariable logistic regression models were used to estimate associations between clinical features and prolonged (≥ 3days) hospital stay...

PURPOSE: We investigated the associations between cardiac parameters and aetiologies of CKD in an exploratory study. METHODS: The study population consisted of 883 participants, 174 controls and 709 patients with aetiologies of CKD including diabetic nephropathy/renovascular KD in diabetes mellitus, hypertensive/renovascular nephropathy, tubulointerstitial nephritis, glomerulonephritis/vasculitis, polycystic KD (PKD), and CKD of unknown origin. Echocardiographic measures included left ventricular (LV) ejection fraction, global longitudinal, area, and radial strain, E/e' ratio, and LV mass index...

Dystrophinopathies, such as Duchenne and Becker muscular dystrophy, frequently lead to cardiomyopathy, being its primary cause of mortality. Detecting cardiac dysfunction early is crucial, but current imaging methods lack insight into microstructural remodeling. This study aims to assess the potential of cardiac magnetic resonance (CMR) parametric mappings for early detection of myocardial involvement in dystrophinopathies and explores whether distinct involvement patterns may indicate impending dysfunction...

We evaluated the prevalence and the clinical associations of liver steatosis (LS) in patients with transfusion-dependent thalassaemia (TDT). We considered 301 TDT patients (177 females, median age = 40.61 years) enrolled in the Extension-Myocardial Iron Overload in Thalassaemia Network, and 25 healthy subjects. Magnetic resonance imaging was used to quantify iron overload and hepatic fat fraction (FF) by T2* technique and cardiac function by cine images. The glucose metabolism was assessed by the oral glucose tolerance test (OGTT)...

S-nitrosylation (SNO) is an emerging paradigm of redox signaling protecting cells against oxidative stress in the heart. Our previous studies demonstrated that valosin-containing protein (VCP), an ATPase-associated protein, is a vital mediator protecting the heart against cardiac stress and ischemic injury. However, the molecular regulations conferred by VCP in the heart are not fully understood. In this study, we explored the potential role of VCP in cardiac protein SNO using multiple cardiac-specific genetically modified mouse models and various analytical techniques including biotin switch assay, liquid chromatography, mass spectrometry, and western blotting...

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality, particularly in type 2 diabetes mellitus (T2DM). Novel markers of insulin resistance and progression of atherosclerosis include the triglycerides and glucose index (TyG index), the triglycerides and body mass index (Tyg-BMI) and the metabolic score for insulin resistance (METS-IR). Establishing independent risk factors for in-hospital death and major adverse cardiac and cerebrovascular events (MACCE) in patients with myocardial infarction (MI) remains critical...

Heart failure (HF) studies typically focus on ischemic and idiopathic heart diseases. Chronic chagasic cardiomyopathy (CCC) is a progressive degenerative inflammatory condition highly prevalent in Latin America that leads to a disturbance of cardiac conduction system. Despite its clinical and epidemiological importance, CCC molecular pathogenesis is poorly understood. Here we characterize and discriminate the plasma metabolomic profile of 15 patients with advanced HF referred for heart transplantation - 8 patients with CCC and 7 with idiopathic dilated cardiomyopathy (IDC) - using gas chromatography/quadrupole time-of-flight mass spectrometry...

BACKGROUND: Lipomyelomeningocele associated with an ulnar club hand in the spectrum of VACTERL association ([costo-]vertebral abnormalities; anal atresia; cardiac defects; tracheal-esophageal abnomalities, including atresia, stenosis, and fistula; renal and radial abnormalities; limb abnormalities; single umbilical artery) is a very rare and infrequently reported phenomenon. Within the fat mass of the lipoma, it is not common to find a well-defined cartilaginous mass with no attachments to the surrounding tissue...

PURPOSE: In a relatively large cohort of thalassemia intermedia (TI) patients, we systematically investigated myocardial iron overload (MIO), function, and replacement fibrosis using cardiac magnetic resonance (CMR), we assessed the clinical determinants of global heart T2* values, and we explored the association between multiparametric CMR findings and cardiac complications. MATERIALS AND METHODS: We considered 254 beta-TI patients (43.14 ± 13...

Ewing's sarcoma of the kidney is a rare tumor. Although renal carcinomas are known to involve the inferior cava, extension of the tumor up to the right atrium is not common. In the majority of cases when the tumor extends into the infrahepatic part of the inferior vena cava, it can be removed from the abdominal approach. Few patients require the use of cardiopulmonary bypass for removal of the tumor in the inferior vena cava and right atrium. The management of patients requiring resection of kidney tumors and right atrial mass is more complicated and requires a team approach consisting of oncosurgeons, cardiac surgeons, and cardiac anesthetists...

Using point of care ultrasound (POCUS) to evaluate patients with syncope in the emergency department facilitates the timely diagnosis of life-threatening pathologies. Case: A 56-year-old woman presented to the emergency department of a hospital in Bogotá, Colombia, for a syncopal episode. Vital signs, physical examination, electrocardiogram, and routine laboratory tests were normal. Cardiac POCUS was performed, which identified an echogenic mass located in the left atrium, measuring 35x28mm, which in left atrial systole appeared to occupy the entire chamber...

BACKGROUND: This study aims to understand the dose-response relationship between alcohol consumption, progression of left ventricular dysfunction (LVD) and/or symptomatic heart failure (HF) in an older European population at risk for HF (stage A) or with pre-HF (stage B). METHODS: This longitudinal, observational, secondary analysis of the St Vincent's Screening TO-Prevent Heart Failure (STOP-HF) follow-up study, excluded former alcohol drinkers and included patients with documented alcohol intake and echocardiography at baseline and follow up ≥18 months...

BACKGROUND: Benign mature teratomas are the most common type of anterior mediastinal germ cell tumor. Mature intrapericardial teratomas are generally diagnosed during infancy because of symptoms of cardiac compression. In contrast, mature adult intrapericardial teratomas are extremely rare, accounting for less than 1% of mature intrapericardial teratomas. We describe herein a case of a mature intrapericardial teratoma in an asymptomatic adult. CASE PRESENTATION: A 52-year-old woman was found by computed tomography during a health checkup to have an anterior mediastinal mass...

OBJECTIVE: This study aimed to report the initial experiences of 115 patients who underwent robotic thoracic surgery using the da Vinci single-port robotic surgical system (Intuitive Surgical). METHODS: Robotic thoracic surgery using the da Vinci single-port robotic surgical system was performed on 115 patients between November 2020 and June 2023. Patient characteristics, intraoperative outcomes, and postoperative outcomes were analyzed retrospectively. RESULTS: The type of surgeries included thymectomy, mediastinal mass excision, anatomical pulmonary resection (including lobectomy and segmentectomy), esophagectomy, and enucleation of esophageal submucosal tumors in 41, 13, 54, 5, and 2 patients, respectively...

BACKGROUND: Previous reports reveal inconsistent findings of right ventricular (RV) changes following pregnancy in subjects with repaired tetralogy of Fallot (rTOF). METHODS: A two-center, retrospective cohort study which included women with rTOF who completed pregnancy that were matched to nulliparous women with rTOF by age at the time of baseline cardiac magnetic resonance (CMR), RV ejection fraction (RVEF), and indexed RV end-diastolic volume (RVEDVi). Pre-pregnancy and postpartum cardiac magnetic resonance (CMR) were analyzed and compared to sequential CMR of nulliparous subjects with rTOF...

Diastolic dysfunction arising from alterations in myocardial structure and/or function is a central component of several cardiovascular disorders, including heart failure with preserved ejection fraction (HFpEF). Basic research aimed at understanding underlying mechanisms contributing to the development of diastolic dysfunction has generally centered upon models of left ventricular (LV) hypertrophy arising from persistent and severe elevations in myocardial afterload (e.g., aortic banding). Mechanisms of hypertrophy-independent diastolic dysfunction, on the other hand, have received less attention, even though overt anatomic LV hypertrophy is absent in many HFpEF patients...
