Heterotopic Caval Valve-in-Valve Procedure for Prosthetic Migration: Two Case R...
Grazina, A; Ferreira, A; Ramos, R; Cacela, DBackground: Heterotopic bicaval stenting or caval valve implantation (CAVI) either with non-dedicated balloon-expandable Sapien™ valves (Edwards Lifesciences) or with dedicated TricValve™ (Products + Features) has emerged as a safe and effective percutaneous treatment for high-risk patients with severe tricuspid regurgitation (TR). One technical difficulty of CAVI is the lack of native calcified structures to a...
Coronary Sinus Reducer Device for the Treatment of Refractory Angina: a Multice...
Ferreira Reis, J; Brízido, C; Madeira, S; Ramos, R; Almeida, M; Cacela, DIntroduction: The coronary sinus Reducer (CSR) device has emerged as a complementary therapy in patients with severe angina refractory to optimal medical therapy and not amenable to revascularization. Our aim was to assess the safety and efficacy of the CSR in a real-world setting. Methods: Twenty-six patients with refractory angina (RA) and evidence of myocardial ischemia attributable to the left coronary arte...
Initial Single-Center Experience of a Standardized Protocol for Invasive Assess...
Vaz Ferreira, V; Ramos, R; Castelo, A; Mendonça, T; Almeida-Morais, L; Pereira-da-Silva, T; Oliveira, E; Viegas, J; Garcia Brás, P; Grazina, AIntroduction: Coronary vasomotion disorders (CVDs), including microvascular angina (MVA) and vasospastic angina (VSA), account for significant morbidity among patients with non-obstructive coronary artery disease (NOCAD). However, protocols for CVD assessment in clinical practice are seldom standardized and may be difficult to implement. Purpose: To assess the safety and feasibility of a comprehensive coronary ...
Remote Invasive Monitoring of Pulmonary Artery Pressures in Heart Failure Patie...
Vaz Ferreira, V; Pereira-da-Silva, T; Cacela, D; Cruz Ferreira, RBackground: Decompensated heart failure (HF) is associated with poor short- and long-term prognosis. Remote invasive monitoring of pulmonary artery pressures (PAP) enables early detection of HF decompensation before symptoms occur and may improve clinical outcomes. We aimed to describe our initial experience with the use of the CardioMEMS™ remote monitoring system in patients with HF, including its safety and e...
Transcatheter Aortic Valve Implantation Outcomes in Patients with Low Flow Low ...
Castelo, A; Grazina, A; Mendonça, T; Rodrigues, I; Garcia Brás, P; Ferreira, V; Ramos, R; Fiarresga, A; Cacela, D; Cruz Ferreira, RBackground: Some studies suggest that patients with low flow low gradient (LF-LG) aortic stenosis (AS) may achieve worse results after undergoing transcatheter aortic valve implantation (TAVI). Purpose: To compare outcomes between LF-LG AS and high gradient (HG) AS patients submitted to TAVI. Methods: Inclusion of 480 consecutive patients who underwent TAVI between 2008 and 2020 at a single tertiary center. Pat...
Not All Pseudoaneurysms Are Femoral. A Transcaval Transcatheter Aortic Valve Re...
Mano, T; Ramos, R; Cacela, D; Patrício, LWe report a case of a 73-year-old male with multiple comorbidities, including postpoliomyelitis severe scoliosis, referred to our tertiary center due to a severe symptomatic aortic stenosis, considered high risk for surgical aortic valve replacement (AVR). Due to unsuitable femoral and subclavian accesses, the patient underwent a transcaval transcatheter AVR (TAVR) procedure, complicated by the development of a...
Prevalence and Prognostic Impact of Apical Sparing Contractility Pattern in Pat...
Ferreira, V; Aguiar Rosa, S; Pereira-da-Silva, T; Rodrigues, I; Gonçalves, A; Mendonça, T; Castelo, A; Branco, LM; Galrinho, A; Fiarresga, A; Ramos, RIntroduction: Prolonged afterload increase in aortic stenosis (AS) may alter left ventricular (LV) contractility, irrespective of LV ejection fraction (LVEF). The prevalence and morbimortality associated with the apical sparing strain pattern (ASP), a typical finding of cardiac amyloidosis (CA), are not fully understood in patients with AS. We assessed the prevalence of the ASP in patients with severe AS and it...
Short and long-term clinical impact of transcatheter aortic valve implantation ...
Guerreiro, C; Ferreira, PC; Teles, RC; Braga, P; Canas da Silva, P; Patrício, L; Silva, JC; Baptista, J; de Sousa Almeida, M; Gama Ribeiro, V; Silva, BIntroduction: The Portuguese National Registry of Transcatheter Aortic Valve Implantation records prospectively the characteristics and outcomes of transcatheter aortic valve implantation (TAVI) procedures in Portugal. Objectives: To assess the 30-day and one-year outcomes of TAVI procedures in Portugal. Methods: We compared TAVI results according to the principal access used (transfemoral (TF) vs. non-transfem...

Short- and Long-Term Outcome After Alcohol Septal Ablation in Obstructive Hyper...
Aguiar Rosa, S; Fiarresga, A; Galrinho, A; Cacela, D; Ramos, R; de Sousa, L; Gonçalves, A; Bernardes, L; Patrício, L; Branco, LM; Cruz Ferreira, RIntroduction: In obstructive hypertrophic cardiomyopathy (HCM), alcohol septal ablation (ASA) can lead to gradient reduction and symptom improvement. We aimed to assess the efficacy and safety of ASA in a long-term outcome study. Methods: We analyzed patients who underwent ASA over a seven-year period in a tertiary center. The primary echocardiographic endpoint was >50% reduction in left ventricular outflow tra...
