Three-dimensional-mapping-guided permanent conduction system pacing in paediatric patients with congenitally corrected transposition of the great arteries.

Aims: In congenitally corrected transposition of the great arteries (CCTGA) the right ventricle (RV) is systemic. Atrioventricular block (AVB) and systolic dysfunction are frequently observed. Permanent pacing of the subpulmonary left ventricle (LV) may worsen RV dysfunction.

Long-term follow-up after recanalisation of aortic arch atresia.

Aims: Aortic arch atresia (AAA) is one of the rarest obstructive defects. The presence of this anomaly in adult age is uncommon. The typical anatomic feature consists of a complete occlusion of the membranous obstruction resulting in an acquired atresia without flow continuity between the proximal and distal segments.

Eisenmenger syndrome and other types of pulmonary arterial hypertension related to adult congenital heart disease.

: Eisenmenger syndrome (ES) is the most advanced form of pulmonary arterial hypertension (PAH) in patients with congenital heart disease (CHD). It is characterised by a severe rise in pulmonary vascular resistance resulting in shunt reversal and cyanosis. : In this paper, an overview of ES and other types of PAH related to CHD (PAH-CHD) in adults is provided.

[Anomalous origin of the right coronary artery from the left sinus of Valsalva: essential role of computed tomography to clarify the coronary artery course and literature review on diagnostic and therapeutic management in 215 cases].

Coronary artery anomalies are among the most confusing topics in cardiology. Although the medical community is increasingly aware that coronary anomalies can be fatal, the reasons for a sudden fatal event and the frequency with which it occurs are generally unclear. In addition, coronary anomalies are usually compatible with normal prenatal myocardial development and postnatal growth and function, even permitting intense athletic activity.

Cardiac thrombi mistaken for metastasis in recurrent melanoma.

Intra-cardiac thrombi can be incidentally found in recurrent melanoma and need careful assessment. An 81-year-old woman, with a history of malignant nasopharyngeal melanoma, was evaluated by echocardiography and cardiac magnetic resonance due to the detection of undefined masses localized both in right atrium and ventricle during contrast-enhanced thoraco-abdominal computed tomography.

Mechanisms of diabetic dyslipidemia: relevance for atherogenesis.

Diabetic dyslipidemia is due to a multiple array of metabolic abnormalities determining a typical phenotype characterized by increased plasma triglycerides, reduced HDL and a preponderance of small, dense LDL. This dyslipidemia, defined as atherogenic dyslipidemia, is thought to be highly responsible for the increased cardiovascular risk in diabetes mellitus. Several lines of evidence indicate that the increased liver production of VLDL is the main underlying defect in atherogenic dyslipidemia.
