RESUMO

Cardiac tumors are neoplasms involving heart structures at any level, meaning the myocardium, valves, and cardiac chambers. When considering cardiac masses, it is not uncommon for surgeons to be surprised when they diagnose one. The real incidence of this complex group of diseases has been explored only after cardiac diagnostic tools became more appropriate. Despite differential diagnosis being relevant, surgical indication is usually requested for all malignant cardiac tumors and also for many types of benign tumors. The development of cardiac imaging techniques, therefore, has been the key point for a better understanding of the history of cardiac tumors and especially of the relevance of surgical indication in such conditions. Systematic and combined applications of echocardiography, cardiac computed tomography and magnetic resonance allow in the majority of case a clear definition of the nature of a newly discovered cardiac mass. The presence of a Li-Fraumeni syndrome seems to be the trigger aspect in accelerating the propensity of developing a cardiac tumor. Despite the revolutionary usefulness of the cardiac imaging techniques available, it is still considered a hazard to diagnose a malignant cardiac mass just with radiological imaging; the mainstay of the final diagnosis stands in surgical excision of the mass and histopathological report.

RESUMO

BACKGROUND: Abnormal ventricular signals (AVS) are the cornerstone of substrate-based ventricular tachycardia (VT) ablation in sinus rhythm. Signal characterization of AVS in ischemic and nonischemic cardiomyopathies has never been performed. OBJECTIVE: The purpose of this study was to describe ventricular signal abnormalities in 3 different pathologies and examine their association with the diastolic component of VT circuits. METHODS: A total of 45 patients (15 ischemic cardiomyopathy [ICM], 15 arrhythmogenic cardiomyopathy [ACM], 15 dilated cardiomyopathy [DCM]) who had undergone VT ablation with >50% of the diastolic pathway of the VT circuit recorded were studied. AVS were classified into late potentials (LPs) and continuous fractionated ventricular signals (CFVS), and their characteristics and correlation with the diastolic pathway of VT circuits were analyzed. RESULTS: Seventy-five VT circuits were analyzed. Bipolar scars were greatest in ICM endocardially (53 cm2 ICM vs 36 cm2 ACM vs 25 cm2 DCM; P = .010) and in ACM epicardially (98 cm2 ACM vs 25 cm2 ICM vs 24 cm2 DCM; P = .005). Location of the VT diastolic interval coincided with AVS location in 54% of VTs in ICM, 89% in ACM, and 72% in DCM (P = .036). There was a trend toward a greater association of diastolic intervals coinciding with LPs than with CFVS (78% vs 57%; P = .052) (69% diastolic intervals in ICM coincided with LPs, 33% with CFVS; P = .063). All patients (100%) with CFVS in ACM had VT diastolic components arising from CFVS (33% ICM, 64% DCM; P = .049). Positive predictive value for LPs vs CFVS was 77.8% vs 56.7%, and sensitivity was 67.3% vs 32.7%, respectively. CONCLUSION: The nature of abnormal signals in different cardiomyopathies reflects underlying pathology. LPs rather than CFVS seem to be more linked to diastolic components of VT circuits, especially in ICM. LPs have greater sensitivity and specificity for VT; however, CFVS may be of more relevance in ACM.

RESUMO

General Practitioners (GPs) are in a prime location to assess patient health needs, knowing clinical history, living habits and risk factors. GPs can identify in healthy people those in which prevention could be useful, in order to avoid or delay some diseases. For this purpose GPs need to change their care model from a waiting model to a proactive model, in order to identify health needs before the development of diseases.
