Recent Techniques in Echocardiography: Two-Dimensional Echocardiography [PDF]

open access: yes, 1979
Conventional M-mode echocardiography is a widely used noninvasive diagnostic technique. It allows bedside assessment of cardiac chamber dimensions, valve motion and left ventricular function.

Glycopolymeric nanoparticles transported by activated platelets protect ischemic myocardium by alleviating PANoptosis through targeting macrophage Dectin‐1

open access: yesBMEMat, EarlyView.
NP‐SF, designed to target macrophage Dectin‐1 and activated platelets, selectively accumulated in ischemic myocardium, where it was taken up by macrophages after platelet hitchhiking. By inhibiting NLRC5‐related PANoptosis, NP‐SF significantly attenuated pathological damage, and effectively preserved cardiac function in a murine ischemia–reperfusion ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Two-dimensional and Doppler echocardiographic findings of congenital coronary artery fistula

open access: yesThe Turkish Journal of Pediatrics, 1992
Three patients with coronary artery fistula confirmed by coronary angiography and surgery were studied using two-dimensional and Doppler echocardiography. Two of these patients had left coronary artery-right ventricle fistula.

Use of speckle-tracking strain in preload-dependent patients, need for cautious interpretation!

open access: yesAnnals of Intensive Care, 2018
Background In critical patients, left ventricular ejection fraction and fractional shortening are used to reflect left ventricular systolic function. An emerging technique, two-dimensional-strain echocardiography, allows assessment of the left ventricle ...

Percutaneous Left Atrial Appendage Closure Using a PFO Occluder After an Incomplete Surgical Ligation

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The case regards a 73‐year‐old male who was referred for consideration of percutaneous left atrial appendage closure. His left atrial appendage was ligated during prior mitral valve surgery, but was noted to be patent on a recent transesophageal echocardiography. An Amulet device was selected based on CT planning.

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.

Diagnosis of Inferior Sinus Venosus Atrial Septal Defects Using Transthoracic Three-Dimensional Echocardiography

open access: yes, 2010
The authors report the cases of 2 patients with symptoms and signs related to severe pulmonary hypertension. Two- dimensional echocardiography demonstrated defects in the posterior portion of the atrial septum.

Comprehensive exploration of unexplained dyspnoea in subjects with normal ejection fraction and low natriuretic peptides

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 879-887, April 2025.
Abstract Background Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF). Aims This study aimed to characterize patients with exertional dyspnoea and normal/near‐to‐normal N‐terminal pro‐brain natriuretic peptide (NT ...

Growth differentiation factor‐15 and N‐terminal pro‐BNP in acute heart failure with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 888-899, April 2025.
Abstract Aims Heart failure with preserved ejection fraction (HFpEF) continues to be an increasingly common health problem associated with a high mortality rate. Elevated levels of Growth differentiation factor‐15 (GDF15) and N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) are reportedly associated with poor clinical outcomes in a broad range of ...
