Multiorgan congestion assessment by venous excess ultrasound score in acute heart failure.

BACKGROUND: This study sought to explore the prevalence and clinical utility of different patterns of multi-organ venous congestion as assessed by the Venous Excess Ultrasound (VExUS) score in hospitalized patients with acute heart failure (HF). METHODS: Consecutive patients admitted for acute HF were prospectively enrolled. Inferior vena cava (IVC) diameter, hepatic vein, portal vein and renal vein Doppler waveforms were assessed at admission and patients were stratified based on VExUS score from 0 to 3, with higher values indicating worse congestion. The clinical score Get With The Guidelines (GWTG)-HF for predicting in-hospital mortality in HF was evaluated. In-hospital mortality was recorded. RESULTS: Two-hundred-ninety patients admitted with acute HF were included and 114 (39%) of them were classified as VExUS score 3 which was the most prevalent group. Patients with VExUS score 3 suffered more frequently from chronic atrial fibrillation, chronic kidney disease and anemia. Parameters independently associated with VExUS score 3 were higher mean E/e' ratio, larger right ventricular size, severe tricuspid regurgitation and impaired right atrial function. VExUS score 3 was associated with in-hospital mortality [OR 8.03, 95% CI (2.25-28.61), p=0.001]. The addition of VExUS score on top of the GWTG-HF score improved the predictability of the model (Δx2=+8.44, p=0.03) for in-hospital mortality, whereas other indices of venous congestion (right atrial function, IVC size) did not. CONCLUSION: Patients admitted with acute HF commonly had severe venous congestion based on VExUS score. VExUS score improved the prediction of in-hospital mortality as compared to other indices of venous congestion.

Multimodality imaging for the global evaluation of aortic stenosis: The valve, the ventricle, the afterload.

Aortic stenosis (AS) is the most common valvular heart disease growing in parallel to the increment of life expectancy. Besides the valve, the degenerative process affects the aorta, impairing its elastic properties and leading to increased systemic resistance. The composite of valvular and systemic afterload mediates ventricular damage. The first step of a thorough evaluation of AS should include a detailed assessment of valvular anatomy and hemodynamics. Subsequently, the ventricle, and the global afterload should be assessed to define disease stage and prognosis. Multimodality imaging is of paramount importance for the comprehensive evaluation of these three elements. Echocardiography is the cornerstone modality whereas Multi-Detector Computed Tomography and Cardiac Magnetic Resonance provide useful complementary information. This review comprehensively examines the merits of these imaging modalities in AS for the evaluation of the valve, the ventricle, and the afterload and ultimately endeavors to integrate them in a holistic assessment of AS.

Low-molecular-weight heparin in radial artery occlusion treatment: the LOW-RAO randomized study.

Radial artery occlusion (RAO) is the commonest complication of transradial catheterization. There is no evidence-based therapy, in the frame of a randomized control study, for the treatment of RAO. The purpose of the LOW-RAO study is to question the hypothesis if low-molecular-weight heparin is effective in the treatment of RAO after transradial coronary catheterization (both angiography and percutaneous coronary intervention). It is a prospective, open label, randomized controlled trial that will randomize 60 patients with RAO, irrespective of symptoms, into two groups, one receiving anticoagulation with low-molecular-weight heparin and the other receiving no treatment. The primary end point is improvement in radial artery patency rate at 4 weeks after the procedure. Clinical trial registration number: NCT04196309 (ClinicalTrials.gov).

Lay abstract Coronary angiogram, a procedure to check if there is any blockage in the heart's blood vessels, is often performed nowadays through a vessel in the wrist, called radial artery. One of the commonest risks of this procedure is the blockage of the radial artery afterward. This could go totally unnoticed; however, it may cause pain, tingling and numbness feeling in the fingers, loss of handgrip power and inability to use the artery for medical reasons in the future. Since there is no definite treatment for this situation up to now, the purpose of the LOW-RAO study is to try to find a solution for this problem. Patients diagnosed with radial artery blockage, will randomly receive for up to 4 weeks an injection that contains a blood-thinner, called low-molecular-weight heparin and is believed to be able to reopen the blocked radial artery. All patients will be regularly followed-up with ultrasounds for a month to check any progress with the blockage.

Intracoronary thrombolysis and stentless primary percutaneous coronary intervention in an ectatic right coronary artery with large thrombus burden.

A 58-year-old man was admitted to our center with an inferior ST-segment elevation myocardial infarction. A coronary angiogram showed an ectatic right coronary artery (RCA) occluded at mid vessel by a significant clot burden quantified by micro-computed tomography. Guide catheter-directed intracoronary thrombolysis with low-dose tenekteplase resulted in regaining RCA flow, when numerous efforts of manual and 'mother-child' thrombectomy had failed to achieve. A stentless strategy was followed with final thrombolysis in myocardial infarction 3 flow and angiographically insignificant stenosis remaining in the RCA. The combination of intracoronary thrombolysis and a stentless strategy is a safe and effective treatment in ST-segment elevation myocardial infarction patients with ectatic arteries and large thrombus burden when repeat manual aspiration thrombectomy fails.
