Meta-Analysis of Ventricular Premature Complexes and Their Relation to Cardiac Mortality in General Populations

Ablating Premature Ventricular Complexes: Justification, Techniques, and Outcomes

“…In general, occasional PVCs in the structurally normal heart are considered benign, 1 though they have been associated with a more than two-fold higher risk of cardiovascular outcomes including stroke 2 and mortality. 3 PVCs commonly arise from the right ventricular (RV) outflow tract (RVOT) and sometimes the left ventricular (LV) outflow tract (LVOT). 4 Other sites for PVCs include the His-Purkinje system, especially the left posterior fascicle (predominantly in young males); endocavitary structures including the papillary muscles, moderator band, and false tendons 5 ; and the annuli of the aortic, pulmonary, and both atrioventricular (AV) valves.…”

Premature ventricular complexes ablation: A trip to the accuracy

“…However, frequent PVC may result in left ventricular systolic dysfunction, a form of PVC-induced cardiomyopathy or PVC-mediated deterioration of pre-existing cardiomyopathy [1]. Frequent PVCs have been associated with a more than 2-fold higher risk of cardiovascular outcomes including stroke and mortality in some reports [2,3]. Radiofrequency ablation (RFA) is increasingly being used in the treatments of symptomatic or frequent PCV.…”

Dual-chamber ICD-CRT implantation in a patient with persistent left superior vena cava: testing skills

“…

A persistent left-superior vena cava (PLSVC) is an uncommon identification with a form of 0.3% to 0.5% of persons in the common population [1][2][3][4][5]. Nevertheless, it is the most common thoracic venous anomaly [6][7][8][9][10].

…”

“…Furthermost of the individuals do not present the symptoms, and the presence of the persistent left superior vena cava is by the way found during or after insertion of a central venous catheter (CVC) or pacemaker electrodes. The correct report of a PLSVC and lack of a right superior vena cava has significant clinical repercussions in definite circumstances, such as oncological therapy, totally implantable vessels catheters, hemodynamic checking in intenive care unit (ICU) or the correct location of pacemakers [1][2][3][4][5][6][7][8][9][10]. The further clinical relevance of the described anomaly could be due to common tachyarrhythmia and conduction disturbances [11][12][13][14][15].…”
