- Interventional cardiology in cancer patients: a position paper from the Portuguese Cardiovascular Intervention Association and the Portuguese Cardio-Oncology Study Group of the Portuguese Society of CardiologyPublication . Menezes, Miguel Nobre; Tavares da Silva, Marta; Magalhaes, Andreia; Melica, Bruno; Toste, Júlia Cristina; Calé, Rita; Almeida, Manuel; Fiuza, Manuela; Infante de Oliveira, EduardoThe field of Cardio-Oncology has grown significantly, especially during the last decade. While awareness of cardiotoxicity due to cancer disease and/or therapies has greatly increased, much of the attention has focused on myocardial systolic disfunction and heart failure. However, coronary and structural heart disease are also a common issue in cancer patients and encompass the full spectrum of cardiotoxicity. While invasive percutaneous or surgical intervention, either is often needed or considered in cancer patients, limited evidence or guidelines are available for dealing with coronary or structural heart disease. The Society for Cardiovascular Angiography and Interventions consensus document published in 2016 is the most comprehensive document regarding this particular issue, but relevant evidence has emerged since, which render some of its considerations outdated. In addition to that, the recent 2022 ESC Guidelines on Cardio-Oncology only briefly discuss this topic. As a result, the Portuguese Association of Cardiovascular Intervention and the Cardio-Oncology Study Group of the Portuguese Society of Cardiology have partnered to produce a position paper to address the issue of cardiac intervention in cancer patients, focusing on percutaneous techniques. A brief review of available evidence is provided, followed by practical considerations. These are based both on the literature as well as accumulated experience with these types of patients, as the authors are either interventional cardiologists, cardiologists with experience in the field of Cardio-Oncology, or both.
- Clinical experience of a cardio-oncology consultation at a tertiary university hospital in Portugal: an observational studyPublication . Fiuza, Manuela; Magalhaes, Andreia; Menezes, Miguel Nobre; Costa, Paula; Ribeiro, Maria Leonor; Marques, Catarina; Brás, Raquel; Vieira, Joana; Afonso, Ana I.; Morais, Pedro; Valente Silva, Beatriz; Costa, Luis; Pinto, Fausto J.Introduction: Heart disease and cancer are the two leading causes of morbidity and mortality worldwide. Advances in cancer screening and management have led to longer survival and better quality of life. Despite this progress, many cancer patients experience cardiovascular complications during and after cancer treatment. This study describes the experience of a cardio-oncology program at tertiary academic hospital. Methods: In this retrospective observational study, cancer patients referred to the CHULN cardio-oncology consultation (COC) between January 2016 and December of 2019 were included. Data collected included: patient demographics, cancer type, reason for referral, cardiovascular risk factors, cardiac and oncologic treatments and clinical outcomes. Results: A total of 520 patients (mean age: 65 ± 14 years; 65% women) were referred to the COC. The main reasons for referral were suspected heart failure (26%), pre-high risk chemotherapy assessment (20%) and decreased LVEF (15%). Pre-existing cardiovascular risk factors were common (79%) and 309 (59%) were taking cardiac medications. The most common type of malignancy was breast cancer (216, 41%) followed by gastrointestinal (139, 27%). More than half received anthracycline-based regimens (303, 58%). Most patients (401; 77%) successfully completed cancer therapy. At the time of last data collection, the majority of patients were alive (430, 83%). Cardiac-related mortality was observed in 16%. Conclusions: The close collaboration between cardiology and oncology teams and timely cardiac monitoring was the key to the majority of patients to completing their prescribed cancer therapy.
- Triple-site pacing for cardiac resynchronization in permanent atrial fibrillation : acute phase results from a prospective observational studyPublication . Marques, Pedro; Menezes, Miguel Nobre; Lima da Silva, Gustavo; Bernardes, Ana; Magalhaes, Andreia; Cortez-Dias, Nuno; Carpinteiro, Luis A.; Sousa, João Carvalho de; Pinto, Fausto J.Introduction and Aim: Multi-site pacing is emerging as a new method for improving response to cardiac resynchronization therapy (CRT), but has been little studied, especially in patients with atrial fibrillation. We aimed to assess the effects of triple-site (Tri-V) vs. biventricular (Bi-V) pacing on hemodynamics and QRS duration. Methods: This was a prospective observational study of patients with permanent atrial fibrillation and ejection fraction <40% undergoing CRT implantation (n=40). One right ventricular (RV) lead was implanted in the apex and another in the right ventricular outflow tract (RVOT) septal wall. A left ventricular (LV) lead was implanted in a conventional venous epicardial position. Cardiac output (using the FloTracTM VigileoTM system), mean QRS and ejection fraction were calculated. Results: Mean cardiac output was 4.81±0.97 l/min with Tri-V, 4.68±0.94 l/min with RVOT septal and LV pacing, and 4.68±0.94 l/min with RV apical and LV pacing (p<0.001 for Tri-V vs. both BiV). Mean pre-implantation QRS was 170±25 ms, 123±18 ms with Tri-V, 141±25 ms with RVOT septal pacing and LV pacing and 145±19 with RV apical and LV pacing (p<0.001 for Tri-V vs. both BiV and pre-implantation). Mean ejection fraction was significantly higher with Tri-V (30±11%) vs. Bi-V pacing (28±12% with RVOT septal and LV pacing and 28±11 with RV apical and LV pacing) and pre-implantation (25±8%). Conclusion: Tri-V pacing produced higher cardiac output and shorter QRS duration than Bi-V pacing. This may have a significant impact on the future of CRT.
