Prognostic Value of Cardiac Magnetic Resonance Imaging in Acute Coronary Syndrome Patients With Troponin Elevation and Nonobstructive Coronary Arteries.

Objective: To define the diagnostic yield of cardiac magnetic resonance (CMR) in differentiating the underlying causes of myocardial infarction with nonobstructive coronary arteries (MINOCA) and to determine the long-term prognostic implications of such diagnoses.

Methods: Cardiac magnetic resonance evaluation was performed in 227 patients (mean age, 56.4±14.

Overview of Optimal Techniques for Pericardiocentesis in Contemporary Practice.

Purpose Of Review: This review summarizes the optimal techniques for the performance of pericardiocentesis in contemporary practice, highlighting the indications, contraindications, and techniques used. Routine pericardial catheter management and the diagnostic role of pericardial fluid analysis are described.

Recent Findings: Echocardiographic-guided pericardiocentesis should be considered the therapy of choice in current clinical practice and may be performed safely despite the presence of coagulopathy and thrombocytopenia in the hands of expert operators.

Usefulness of Mitral Valve Prosthetic or Bioprosthetic Time Velocity Index Ratio to Detect Prosthetic or Bioprosthetic Mitral Valve Dysfunction.

This study aimed to investigate the utility of transthoracic echocardiographic (TTE) Doppler-derived parameters in detection of mitral prosthetic dysfunction and to define optimal cut-off values for identification of such dysfunction by valve type. In total, 971 TTE studies (647 mechanical prostheses; 324 bioprostheses) were compared with transesophageal echocardiography for evaluation of mitral prosthesis function. Among all prostheses, mitral valve prosthesis (MVP) ratio (ratio of time velocity integral of MVP to that of left ventricular outflow tract; odds ratio [OR] 10.

Safety and efficacy of microwave ablation for medically inoperable colorectal pulmonary metastases: Single-centre experience.

Introduction: To evaluate the safety and therapeutic efficacy of percutaneous microwave ablation (MWA) for colorectal pulmonary metastases.

Methods: Retrospective review of CT-guided lung MWA at a single tertiary institution. Adverse events within 30 days of MWA were considered procedure-related complications.
