Validation of a Heart Failure Risk Score in a Cohort of Cardiac Resynchronizati...
Cardoso, I; Cunha, P; Laranjo, S; Grazina, A; Viegas, J; Portugal, G; Valente, B; Lousinha, A; Brás, P; Brás, M; Cruz Ferreira, R; Oliveira, MThe heart failure risk status (HFRS) is a validated dynamic tool for risk score prediction, based on the TriageHF™ algorithm (Medtronic, Minneapolis, MN, USA), for the occurrence of a heart failure (HF) event in the 30 days following a remote monitoring (RM) transmission. The aim of this study was to evaluate the accuracy of the HFRS in predicting an unplanned hospital admission due to HF decompensation in a re...
Long-Term Outcomes of Non-Contact Multi-Electrode Balloon Catheter Mapping-Guid...
Almeida, I; Lousinha, A; Silva Cunha, P; Valente, B; Paulo, M; Delgado, AS; Cruz Ferreira, R; Oliveira, MMIntroduction: The outflow tract (OT) regions of the ventricles are a common location of origin for idiopathic ventricular arrhythmias (VA). Non-contact mapping (NCM) with a multi-electrode balloon catheter Ensite-Array enables three-dimensional reconstruction of the geometry of the cardiac chambers and accurate mapping of the propagation map, based on a single beat analysis, facilitating the ablation and contri...
Impact of Substrate-Based Ablation for Ventricular Tachycardia in Patients with...
Oliveira, MM; Cunha, PS; Valente, B; Portugal, G; Lousinha, A; Pereira, M; Braz, M; Delgado, A; Cruz Ferreira, RIntroduction: Recurrent ventricular tachycardia (VT) episodes have a negative impact on the clinical outcome of implantable cardioverter-defibrillator (ICD) patients. Modification of the arrhythmogenic substrate has been used as a promising approach for treating recurrent VTs. However, there are limited data on long-term follow-up. Aim: To analyze long-term results of VT substrate-based ablation using high-dens...
Importance of Monitoring Zones in the Detection of Arrhythmias in Patients with...
Aguiar Rosa, S; Silva Cunha, P; Lousinha, A; Valente, B; Delgado, AS; Pimenta, R; Brás, M; Coutinho Cruz, M; Portugal, G; Viveiros Monteiro, AINTRODUCTION: Implantable cardioverter-defibrillator (ICD) monitoring zones (MZ) provide passive features that do not interfere with the functioning of active treatment zones. However, it is not known for certain whether programming an MZ affects arrhythmia detection by the ICD. The aim of the present study is to assess the clinical relevance of MZ in a population of patients with ICDs. METHODS: In this retrosp...
Impact on Long-Term Cardiovascular Outcomes of Different Cardiac Resynchronizat...
Rodrigues, I; Abreu, A; Oliveira, MM; Silva Cunha, P; Santa Clara, H; Osório, P; Lousinha, A; Valente, B; Portugal, G; Rio, P; Morais, L; Santos, VINTRODUCTION: There is a lack of consensus on the definition of response to cardiac resynchronization therapy (CRT), and it is not clear which response criteria have most influence on cardiac event-free survival. OBJECTIVES: To assess the predictive value of various response criteria in patients undergoing CRT and the agreement between them. METHODS: We performed a secondary analysis of the BETTER-HF trial. Pat...
A Link to Better Care: The Effect of Remote Monitoring on Long-Term Adverse Car...
Portugal, G; Cunha, PS; Valente, B; Feliciano, J; Lousinha, A; Alves, S; Braz, M; Pimenta, R; Delgado, AS; Oliveira, MM; Cruz Ferreira, RAIMS: There are conflicting data regarding the clinical benefits of device-based remote monitoring (RM). We sought to assess the effect of device-based RM on long-term clinical outcomes in recipients of implantable cardioverter-defibrillators (ICDs). METHODS: We assessed the incidence of adverse cardiac events, overall mortality and device therapy efficacy and safety in a propensity score-matched cohort of pati...
Influence of Remote Monitoring on Long-Term Cardiovascular Outcomes after Cardi...
Portugal, G; Cunha, PS; Valente, B; Feliciano, J; Lousinha, A; Alves, S; Braz, M; Pimenta, R; Delgado, AS; Oliveira, MM; Cruz Ferreira, RAIMS: Device-based remote monitoring (RM) has been linked to improved clinical outcomes at short to medium-term follow-up. Whether this benefit extends to long-term follow-up is unknown. We sought to assess the effect of device-based RM on long-term clinical outcomes in recipients of implantable cardioverter-defibrillators (ICD). METHODS: We performed a retrospective cohort study of consecutive patients who und...
Predictive Impact on Medium-Term Mortality of Hematological Parameters in Acute...
Timóteo, AT; Papoila, AL; Lousinha, A; Alves, M; Miranda, F; Ferreira, ML; Cruz Ferreira, RBACKGROUND: Red Cell Distribution Width (RDW) prognostic value in patients with Acute Coronary Syndrome (ACS) has been well validated whereas that of Platelet Distribution Width (PDW) is less well known. OBJECTIVES: Investigate the incremental prognostic value, on top of GRACE risk score, of a new variable resulting from the combination of RDW and PDW. METHODS: Consecutive patients with ACS. Complete blood coun...
Short QT Syndrome Presenting As Syncope: How Short Is Too Short?
Portugal, G; Oliveira, MM; Silva Cunha, P; Filipa, F; Lousinha, A; Fiarresga, A; Nogueira da Silva, M; Cruz Ferreira, RWe report the case of a 52-year-old man who presented to our emergency department (ED) after three episodes of syncope in the seven hours before admission. During his stay in the ED he had recurrent ventricular tachycardia (VT) requiring external electrical cardioversion. A 12-lead electrocardiogram (ECG) showed a short QT (SQT) interval (270 ms, QTc 327 ms), with frequent R-on-T extrasystoles triggering sustai...
Femoral Approach: an Exceptional Alternative for Permanent Pacemaker Implantation
Valente, B; Conceição, JM; Nogueira da Silva, M; Oliveira, MM; Silva Cunha, P; Lousinha, A; Galrinho, A; Cruz Ferreira, RThe classic transvenous implantation of a permanent pacemaker in a pectoral location may be precluded by obstruction of venous access through the superior vena cava or recent infection at the implant site. When these barriers to the procedure are bilateral and there are also contraindications or technical difficulties to performing a thoracotomy for an epicardial approach, the femoral vein, although rarely used...
