Background: Technological development has offered laparoscopic colorectal surgeons new video systems to improve depth perception and perform difficult task in limited space. The aim of this study was to assess the cognitive burden and motion sickness for surgeons during 3D, 2D-4 K or 3D-4 K laparoscopic colorectal procedures and to report post-operative data with the different video systems employed.

Methods: Patients were assigned to either 3D, 2D-4 K or 3D-4 K video and two questionnaires (Simulator Sickness Questionnaire-SSQ- and NASA Task Load Index -TLX) were used during elective laparoscopic colorectal resections (October 2020-August 2022) from two operating surgeons.

Article Synopsis
  • * This problem often stems from a lack of knowledge about guidelines, a defensive medicine mindset, or repeated requests from patients and families.
  • * A collaborative effort among cardiologists in the Veneto Region of Italy has produced guidelines for follow-up on common cardiovascular diseases, focusing on appropriate strategies and scientific evidence to help address issues of test inappropriateness and economic viability.

Background: Patients with asymptomatic left ventricular systolic dysfunction (ALVSD) have an increased risk of heart failure (HF) and a worse life expectancy. Since valuable therapies may prevent such dismal evolution, screening programs for ALVSD have recently been advocated to detect as early as possible such ominous condition. Echocardiography represents the gold standard for the assessment of ALVSD but its indiscriminate use in screening programs is impractical.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heart muscle disease characterized by myocardial necrosis followed by fibrous-fatty replacement. The pathologic process constitutes the basis for ventricular arrhythmias due to re-entrant circuits. Even if this genetic disease is transmitted in the majority of cases with autosomal dominant trait, in all reported series ARVC is prevalent in men.

Aims: To describe a patient showing monomorphic ventricular tachycardia, ECG aspect of Brugada syndrome, and structural heart abnormalities due to a homozygous missense mutation in SCN5A.

Methods And Results: Thirteen subjects (six males, seven females, mean age 46 +/- 22 years) belonging to the same family underwent physical examination, basal biochemical marker detection, 12-lead ECG, Holter ECG, signal-averaged ECG, echocardiogram and genetic analysis. The proband underwent a stress test together with left and right ventricular angiography and electrophysiological study.

Aims: The aims of our study were to evaluate late potential changes during long-term follow-up in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and to correlate these results with echocardiographic findings and sustained ventricular tachycardia (VT) occurrence.

Methods And Results: We studied 31 patients (22 males and 9 females; mean age 29+/-16) during 8 years of follow-up by signal-averaged ECG (SAECG) and echocardiography. Ten subjects experienced episodes of sustained VT.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a primary myocardial pathology usually diagnosed at a young age. Although ARVC is characterized by well-known clinical and instrumental features, the diagnosis in older patients can sometimes be difficult, due to the frequent left ventricular involvement and possible concomitant coronary artery disease. In the present study, we describe two female patients in whom morphological and kinetic abnormalities of the right ventricle, in keeping with the diagnosis of ARVC, appeared when they were aged in their fifties.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy characterized by progressive myocardial atrophy with fibrofatty replacement. The recent identification of causative mutations in plakoglobin, desmoplakin (DSP), and plakophilin-2 (PKP2) genes led to the hypothesis that ARVC is due to desmosomal defects. Therefore, desmoglein-2 (DSG2), the only desmoglein isoform expressed in cardiac myocytes, was screened in subjects with ARVC.

Objectives: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a cardiac disease characterised by myocardial necrosis followed by fibro-fatty substitution leading to the onset of ventricular arrhythmias. The aim of the present study was to analyse pregnancy in women affected by this condition.

Study Design: Six women affected by ARVC/D who underwent a pregnancy were studied with a follow-up programme, consisting of 12-lead ECG, signal-averaged ECG, 24-h ECG and two-dimensional and Doppler echocardiogram performed before the beginning of the pregnancy, at 3rd and 7th month of gestation and after the delivery.

Aims: To characterize the clinical profile of patients belonging to families affected with autosomal dominant arrhythmogenic right ventricular cardiomyopathy (ARVC) due to mutations of the gene encoding for the cell-to-cell adhesion protein desmoplakin (DSP).

Methods And Results: Thirty-eight subjects belonging to four families showing different DSP mutations (three missense and one in the intron-exon splicing region) underwent clinical and genetic investigation, including annual 12-lead ECG, signal averaged ECG, 24 h Holter ECG, and two-dimensional echocardiography. Twenty-six family members (11 males and 15 females) were found to carry a DSP mutation.

Background: Three-dimensional electroanatomic voltage mapping offers the potential to identify low-voltage areas that correspond to regions of right ventricular (RV) myocardial loss and fibrofatty replacement in patients with arrhythmogenic RV cardiomyopathy/dysplasia (ARVC/D).

Methods And Results: Thirty-one consecutive patients (22 men and 9 women; mean age, 30.8+/-7 years) who fulfilled the criteria of the Task Force of the European Society of Cardiology and International Society and Federation of Cardiology (ESC/ISFC) for ARVC/D diagnosis after noninvasive clinical evaluation underwent further invasive study including RV electroanatomic voltage mapping and endomyocardial biopsy (EMB) to validate the diagnosis.

Arrhythmogenic right ventricular cardiomyopathy type 1 (ARVD1) is an autosomal dominant disorder characterised by progressive degeneration of right ventricular myocardium, arrhythmias and risk of sudden death. By linkage analysis, we previously mapped the involved gene to chromosome 14q24.3.

Objective: Left ventricular hypertrophy (LVH) is associated with an increased risk for cardiovascular morbidity and mortality. Epidemiological studies suggest that LVH may be influenced by genetic factors. However, the evidence associating individual genes with left ventricular (LV) mass is inconsistent and contradictory.
