Hemodynamic outcomes after valve-in-valve transcatheter aortic valve replacement: a single-center experience.

BACKGROUND: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) has emerged as a safe, effective alternative to redo aortic valve surgery in high-risk patients with degenerated surgical bioprosthetic valves. However, ViV-TAVR has been associated high postprocedural valvular gradients, compared with TAVR for native-valve aortic stenosis. METHODS: We performed a retrospective study of all patients who underwent ViV-TAVR for a degenerated aortic valve bioprosthesis between January 1, 2013 and March 31, 2019 at our center. The primary outcome was postprocedural mean aortic valve gradient. Outcomes were compared across surgical valve type (stented versus stentless), surgical valve internal diameter (≤19 versus >19 mm), and transcatheter aortic valve type (self-expanding vs. balloon-expandable). RESULTS: Overall, 89 patients underwent ViV-TAVR. Mean age was 69.0±12.6 years, 61% were male, and median Society of Thoracic Surgeons Predicted Risk of Mortality score was 5.4 [interquartile range, 3.2-8.5]. Bioprosthesis mode of failure was stenotic (58% of patients), regurgitant (24%), or mixed (18%). The surgical valve was stented in 75% of patients and stentless in 25%. The surgical valve's internal diameter was ≤19 mm in 45% of cases. A balloon-expandable transcatheter valve was used in 53% of procedures. Baseline aortic valve area and mean gradients were 0.87±0.31 cm2 and 36±18 mmHg, respectively. These improved after ViV-TAVR to 1.38±0.55 cm2 and 18±11 mmHg at a median outpatient follow-up of 331 [67-394] days. Higher postprocedural mean gradients were associated with surgical valves having an internal diameter ≤19 mm (24±13 versus 16±8, P=0.002) and with stented surgical valves (22±11 versus 12±6, P<0.001). CONCLUSIONS: ViV-TAVR is an effective option for treating degenerated surgical aortic bioprostheses, with acceptable hemodynamic outcomes. Small surgical valves and stented surgical valves are associated with higher postprocedural gradients.

The cancer patient and cardiology.

Advances in cancer treatments have improved clinical outcomes, leading to an increasing population of cancer survivors. However, this success is associated with high rates of short- and long-term cardiovascular (CV) toxicities. The number and variety of cancer drugs and CV toxicity types make long-term care a complex undertaking. This requires a multidisciplinary approach that includes expertise in oncology, cardiology and other related specialties, and has led to the development of the cardio-oncology subspecialty. This paper aims to provide an overview of the main adverse events, risk assessment and risk mitigation strategies, early diagnosis, medical and complementary strategies for prevention and management, and long-term follow-up strategies for patients at risk of cancer therapy-related cardiotoxicities. Research to better define strategies for early identification, follow-up and management is highly necessary. Although the academic cardio-oncology community may be the best vehicle to foster awareness and research in this field, additional stakeholders (industry, government agencies and patient organizations) must be involved to facilitate cross-discipline interactions and help in the design and funding of cardio-oncology trials. The overarching goals of cardio-oncology are to assist clinicians in providing optimal care for patients with cancer and cancer survivors, to provide insight into future areas of research and to search for collaborations with industry, funding bodies and patient advocates. However, many unmet needs remain. This document is the product of brainstorming presentations and active discussions held at the Cardiovascular Round Table workshop organized in January 2020 by the European Society of Cardiology.

Contemporary impacts of a cancer diagnosis on survival following in-hospital cardiac arrest.

AIM: The objective of this study was to determine whether survival and post-arrest procedural utilization following in-hospital cardiac arrest (IHCA) differ in patients with and without comorbid cancer. METHODS: We retrospectively reviewed all adult (age ≥18 years old) hospital admissions complicated by IHCA from 2003 to 2014 using the National Inpatient Sample (NIS) dataset. Utilizing propensity score matching using age, gender, race, insurance, all hospital level variables, HCUP mortality score, diabetes, hypertension and cardiopulmonary resuscitation use, rates of survival to hospital discharge and post-arrest procedural utilization were compared. RESULTS: From 2003 to 2014, there were a total of 1,893,768 hospitalizations complicated by IHCA, of which 112,926 occurred in patients with history of cancer. In a propensity matched cohort from 2012 to 2014, those with cancer were less likely to survive the hospitalization (31% vs. 46%, p < 0.0001). Following an IHCA, rates of procedural utilization in patients with cancer were significantly less when compared to those without a concurrent malignancy: coronary angiography (4.0% vs. 13.0%), percutaneous coronary intervention (2.2% and 8.0%), targeted temperature management (0.8% vs. 6.0%); p < 0.0001 for all comparisons. This patient population was less likely to have acute coronary syndrome (12.6% vs. 27.0%) or congestive heart failure (24.5% vs. 38.2%); p < 0.0001 for both comparisons. Survival improved in both groups over the study period (p < 0.0001). CONCLUSIONS: Patients with a history of cancer who sustain IHCA are less likely to receive post-arrest procedures and survive to hospital discharge. Given the expected rise in the rates of cancer survivorship, these findings highlight the need for broader application of potentially life-saving interventions to lower risk cancer patients who have sustained a cardiac arrest.

Cardio-Onco-Hematología en la práctica clínica. Documento de consenso y recomendaciones / Cardio-Onco-Hematology in clinical practice. Position paper and recommendations

Los avances en la detección precoz y el tratamiento del cáncer han reducido de manera significativa la mortalidad de los pacientes. Sin embargo, mejorar el pronóstico no es solo curar el tumor, sino prevenir, diagnosticar y tratar eficazmente las complicaciones derivadas de las terapias onco-hematológicas. La toxicidad cardiovascular es un problema ampliamente reconocido con múltiples esquemas terapéuticos; sin embargo, la evidencia científica en el manejo de las complicaciones cardiovasculares de pacientes onco-hematológicos es escasa, pues sistemáticamente se ha excluido de los ensayos clínicos a estos enfermos y las recomendaciones actuales están basadas en consensos de expertos. Es imprescindible crear equipos multidisciplinarios locales para optimizar los resultados en salud de los supervivientes al cáncer. Una preocupación excesiva por la aparición de toxicidad cardiovascular puede impedir terapias potencialmente curativas, mientras que la subestimación de este riesgo compromete el pronóstico vital a largo plazo. El objetivo de este documento, elaborado en colaboración con la Sociedad Española de Cardiología, la Sociedad Española de Oncología Médica, la Sociedad Española de Oncología Radioterápica y la Sociedad Española de Hematología, es actualizar los conocimientos aplicables a la práctica clínica diaria de la cardio-onco-hematología y promover el desarrollo de equipos multidisciplinarios locales que mejoren la salud cardiovascular de los pacientes con cáncer (AU)

Improvements in early detection and treatment have markedly reduced cancer-related mortality. However survival not only depends on effectively cure cancer, but prevention, diagnosis and treatment of cancer-related complications is also needed. Cardiovascular toxicity is a widespread problem across many classes of therapeutic schemes, however scientific evidence in the management of cardiovascular complications of onco-hematological patients is scarce, as these patients have been systematically excluded from clinical trials and current recommendations are based on expert consensus. Multidisciplinary teams are mandatory to decrease morbidity and mortality from both cardiotoxicity and cancer itself. An excessive concern for the occurrence of cardiovascular toxicity, can avoid potentially curative therapies, while underestimating this risk, increases long-term mortality of cancer survivors. The objective of this consensus document, developed in collaboration of the Spanish Society of Cardiology, the Spanish Society of Medical Oncology, the Spanish Society of Radiation Oncology and the Spanish Society of Hematology, is to update the necessary concepts and expertise on cardio-onco-hematology that enable its application in daily clinical practice and to promote the development of local multidisciplinary teams, to improve the cardiovascular health of patients with cancer (AU)
