Full-Scale 3D Printing as a Guide to Right Ventricular Pseudoaneurysm Due to Chronic Pacemaker Lead Erosion.

Background: Ventricular pseudoaneurysm formation due to longstanding lead erosion is rare, and standardized guidelines for diagnosis and management are limited.

Case Summary: We present a case of a right ventricular pseudoaneurysm noted on computed tomography after a patient with a pacemaker, originally placed in 2013, was admitted for respiratory failure. PolyJet three-dimensional printing was employed to assist in presurgical planning and evaluating the spatial anatomic relationship of the lead to the ventricular outpouching.

Resistive index of central retinal artery is a bioimaging biomarker for severity of diabetic retinopathy.

Background: The present study was undertaken to assess the resistive index (RI) of central retinal artery (CRA) as a bioimaging biomarker for the severity of diabetic retinopathy (DR), for the first time.

Methods: Eighty-one consecutive patients of type 2 diabetes mellitus between the ages of 40 and 70 years were included in a tertiary care center-based cross sectional study. Severity of retinopathy was assessed according to Early Treatment Diabetic Retinopathy Study (ETDRS) classification: diabetes mellitus with no retinopathy (No DR) (n = 26); non-proliferative diabetic retinopathy (NPDR) (n = 29); and proliferative diabetic retinopathy (PDR) (n = 26).

Secondary Hypertension and Complications: Diagnosis and Role of Imaging.

Hypertension is a common problem; if left untreated, it can result in significant complications, including those involving the cardiovascular system and end organs. Approximately 10% of patients with hypertension are classified as having , defined as hypertension attributable to a specific and potentially remediable cause. The evaluation for secondary hypertension typically begins with acquiring the patient history and performing a physical examination and screening laboratory tests.

Comparison of Drug-Eluting Balloon and Standard Balloon Angioplasty for Infrapopliteal Arterial Diseases in Diabetic Patients.

Objective: To consider the clinical outcomes and restenosis rates of drug-eluting balloons (DEBs) and percutaneous transluminal angioplasty (PTA) in diabetic patients with infrapopliteal (IP) arterial disease.

Materials And Methods: This retrospective, single-center study included 51 patients (37 males; mean age: 63.43 ± 9.

Evaluation of right atrium-to-right ventricle diameter ratio on computed tomography pulmonary angiography: Prediction of adverse outcome and 30-day mortality.

Objective: The aim of this study was to examine the association between right atrium (RA) and right ventricle (RV) diameters on computed tomography (CT) pulmonary angiography in response to acute pulmonary embolism (APE), in addition to 30-day mortality and adverse outcomes in patients with APE.

Methods: This retrospective study was accepted by the institutional ethics committee. From January 2013 to March 2014, 79 hospitalized adult patients with symptomatic APE were included.
