Real-time three-dimensional ultrasound : a valuable new tool in preoperative assessment of complex congenital cardiac disease [PDF]
, 2003 Evaluating complex cardiac defects in small children preoperatively requires multiple diagnostic procedures including echocardiography, and also invasive methods such as cardiac catheterisation, computer-tomography and magnetic resonance imaging.

Shortening of the Short Refractory Periods in Short QT Syndrome. [PDF]
, 2017 BACKGROUND: Diagnosis of short QT syndrome (SQTS) remains difficult in case of borderline QT values as often found in normal populations. Whether some shortening of refractory periods (RP) may help in differentiating SQTS from normal subjects is unknown.

ESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...

A phenomap of TTR amyloidosis to aid diagnostic screening
ESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.

A study of the role of nitric oxide in the mechanism of action of hydroalcoholic extract of saffron (Crocus sativus) on the electrophysiological properties of the rabbit atrioventricular node [PDF]
, 2007 Biologically active substances of plant origin represent an essential branch of modern cardiovascular pharmacotherapy. Furthermore, drugs of plant origin have the advantage of weaker adverse effects and lower prices than synthetic drugs.

ESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

Atrioventricular Reciprocating Tachycardia Mediated by Twin Atrioventricular Nodes
JACC: Clinical Electrophysiology, 2016 A 21-year-old man with univentricular and uniatrial heart came for a third attempt at ablation of recurrent supraventricular tachycardia. He had undergone a previous cardiac surgery of a Blalock–Taussig shunt, and bidirectional Glenn, and the electrophysiological study revealed an ...
