Article Synopsis
  • - The study evaluates the effectiveness of quantitative perfusion cardiac magnetic resonance (QP-CMR) imaging in detecting significant coronary artery disease (CAD) in patients with a history of CAD and new chest pain, comparing it with visual assessment of stress perfusion CMR and quantitative PET imaging.
  • - Involving 145 patients with prior heart issues, the research found QP-CMR's sensitivity at 66%, which is lower than PET at 80%, but its specificity is on par with both v-CMR and PET at about 60-63%.
  • - Overall, the study concludes that QP-CMR's diagnostic performance is similar to that of both other imaging methods for identifying hemodynamically significant CAD, defined by fractional

Aims: In chronic coronary syndrome (CCS) patients with documented coronary artery disease (CAD), ischaemia detection by myocardial perfusion imaging (MPI) and an invasive approach are viable diagnostic strategies. We compared the diagnostic performance of quantitative flow ratio (QFR) with single-photon emission computed tomography (SPECT), positron emission tomography (PET), and cardiac magnetic resonance imaging (CMR) in patients with prior CAD [previous percutaneous coronary intervention (PCI) and/or myocardial infarction (MI)].

Methods And Results: This PACIFIC-2 sub-study evaluated 189 CCS patients with prior CAD for inclusion.

Purpose: The present study assesses different left atrial (LA) strain approaches in relation to atrial fibrillation (AF) recurrence after ablation and compares LA feature tracking (FT) strain to novel rapid LA strain approaches in AF patients.

Methods: This retrospective single-center study comprised of 110 prospectively recruited AF patients who underwent cardiac magnetic resonance (CMR) imaging in sinus rhythm prior to their first pulmonary vein isolation ablation. LA rapid strain (long axis strain and atrioventricular (AV)-junction strain), LA FT strain, and LA volumes were derived from 2-chamber and 4-chamber cine images.

Aims: The diagnostic performance of non-invasive imaging in patients with prior coronary artery disease (CAD) has not been tested in prospective head-to-head comparative studies. The aim of this study was to compare the diagnostic performance of qualitative single-photon emission computed tomography (SPECT), quantitative positron emission tomography (PET), and qualitative magnetic resonance imaging (MRI) in patients with a prior myocardial infarction (MI) or percutaneous coronary intervention (PCI).

Methods And Results: In this prospective clinical study, all patients with prior MI and/or PCI and new symptoms of ischaemic CAD underwent 99mTc-tetrofosmin SPECT, [15O]H2O PET, and MRI, followed by invasive coronary angiography with fractional flow reserve (FFR) in all coronary arteries.

Background: Orthostatic hypertension (OHT) is the clinical opposite to orthostatic hypotension and is an under-recognized and poorly understood clinical phenomenon. Patients may experience disabling symptoms such as dizziness, chest pain, and shortness of breath. In addition, OHT is associated with important clinical outcomes such as silent cerebral infarcts and cognitive decline.

Background: Endosonography is being implemented rapidly in pulmonary medicine for the diagnosis and staging of lung cancer, the assessment of sarcoidosis, and the assessment of mediastinal lesions. Although serious adverse events (SAEs) have been described, safety data outside cohort studies are scarce.

Objective: To assess the SAE and mortality rate of EUS-guided FNA (EUS-FNA) and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) for mediastinal and/or hilar analysis.

Background: Endosonography combined with fine needle aspiration (FNA) is a minimally invasive technique for intrathoracic mediastinal nodal sampling. The value of endosonography with FNA for the diagnosis of malignant mediastinal lymphoma is under debate. In this study, the sensitivity and negative predictive value of endosonography for the assessment of primary versus recurrent malignant lymphoma were assessed.

Importance: Tissue verification of noncaseating granulomas is recommended for the diagnosis of sarcoidosis. Bronchoscopy with transbronchial lung biopsies, the current diagnostic standard, has moderate sensitivity in assessing granulomas. Endosonography with intrathoracic nodal aspiration appears to be a promising diagnostic technique.

Introduction: Selected patients with stage III (N2/N3) non-small cell lung cancer (NSCLC) who are downstaged to N0 by chemoradiation therapy might benefit from subsequent surgical resection of the tumor. How mediastinal lymph nodes can be best reevaluated is subject of debate. Transesophageal ultrasound-guided fine-needle aspiration (EUS-FNA) is a minimally invasive technique to sample mediastinal nodes.

Background: Obtaining tissue from a para-aortal lymph node or tumor is a challenge that currently requires invasive surgical procedures. Para-aortic lung tumors can be clearly visualized by EUS. Although the accessibility of lesions adjacent to the esophagus is well documented, the para-aortic region has never been systematically explored.
