The diagnostic accuracy of the cardiothoracic ratio on chest X-ray to detect left ventricular (LV) enlargement has not been well defined despite its traditional association with cardiomegaly. We aimed to determine whether the cardiothoracic ratio can accurately predict LV enlargement based on indexed linear measurements of the LV on transthoracic echocardiography (TTE). We included consecutive patients who had a TTE and a posteroanterior chest X-ray performed within 90 days of each other at a tertiary care center. LV size was determined by measuring the LV end-diastolic dimension (LVEDD) and LV end-diastolic dimension indexed (LVEDDI) to body surface area. The cardiothoracic ratio was calculated by dividing the maximum transverse diameter of the cardiac silhouette by the maximum transverse diameter of the right and left lung boundaries. 173 patients were included in the study (mean age 68 ± 15 years, 49.1% female). Mean cardiothoracic ratio was 0.56 ± 0.09, and the mean LVEDD and indexed LVEDDI were of 47 ± 8.6 mm and dimension of 27 ± 4.5 mm/m respectively. There was no significant correlation between the cardiothoracic ratio measured on chest X-ray and either the LVEDD or LVEDDI measured on TTE (r = 0.011, p = 0.879; r = 0.122, p = 0.111). The ability of the cardiothoracic ratio to predict LV enlargement (defined as LVEDDI > 30 mm/m) was not statistically significant. The cardiothoracic ratio on chest X-ray is not a predictor of LV enlargement based on indexed linear measurements of the LV by TTE.

Background: To evaluate the clinical outcomes of valve-in-valve transcatheter aortic valve replacement (ViV TAVR) with newer-generation self-expanding Evolut valves according to the size of the failed surgical bioprosthesis.
Methods: This single-center retrospective study evaluated consecutive patients undergoing ViV TAVR with the Evolut Pro/Pro+/Fx between 2018 and 2022. These patients were compared based on the true internal diameter (ID) of the failed bioprosthesis, specifically ≤19 mm (small group) vs.

Introduction: Chemoradiation followed by durvalumab is considered a standard approach for patients with locally advanced NSCLC. With improvements in perioperative and neoadjuvant approaches, there is renewed interest in offering surgery to carefully selected patients with cT3/4N2 stage IIIB cancer. We sought to assess survival outcomes after surgery as part of a multimodality treatment regimen for these patients.

Background: Lung cancer is a leading cause of cancer-related mortality. Non-small cell lung cancer (NSCLC) comprises 85% of cases with rising incidence among never-smokers (NS). This study seeks to compare clinical, imaging, pathology, and outcomes between NS and ever-smokers (S) NSCLC patients to identify significant differences if any.

Background: It is crucial to distinguish type-1 myocardial infarction (T1MI) from type-2 myocardial infarction (T2MI) at admission and during hospitalization to avoid unnecessary invasive exams and inappropriate admissions to the acute cardiac care unit.
Objectives: The purpose of the study was to define a simple profile derived from commonly used biomarkers to differentiate T1MI from T2MI.
Methods: We prospectively enrolled in an observational study 213 iconsecutive patients with a provisional diagnosis of non-ST-elevation acute myocardial infarction (NSTEMI) admitted to the Cardiology Department.

Objectives: Re-operations due to material degeneration carry a burden for patients with congenital heart disease (CHD). The study aim was to compare rapid vs. slow degeneration of biomaterials in CHD patients.
