Abstract
Abstract
Introduction
Cardiac Allograft Vasculopathy (CAV) and Acute Rejection (AR) surveillance after a Heart Transplant (HT) is based on the performance of Coronary Angiography (CAG) that requires arterial access and Endomyocardial Biopsy, normally Ventricular Right (RV-EMB), which requires venous access. Depending on the clinical indication, HT patients are referred to the cath lab to perform both procedures in the same day. We evaluated the effectiveness and safety of performing a Left Ventricular Endomyocardial Biopsy (LV-EMB) and a CAG with a single artery access.
Methods
We retrospectively analyzed HT patients referred to cath lab for surveillance of AR and CAV on the same day between January 2018 and March 2021. We compared the procedures performed with two accesses (Group 1; CAG + RV-EMB) versus procedures made with a single artery access (Group 2; CAG + LV-EMB).
Results
121 Procedures were performed within the indicated period, 96 (79.3%) belong to the double access group and 25 (20.7%) to the single access group. All procedures were successful and without major complications. There were only 2 cases of insufficient sample, one for each group. Baseline characteristics in both groups and AR or CAV presence were similar (table). Total procedure time (52.00±15.30 vs 33.36±18.69min) and fluoroscopic time (10.70±4.89 vs 6.84±1.82 min) were significantly shorter in the single access group (p<0.001 in both). The most used arterial access in group 2 was the right radial artery (15; 60%) followed by the right femoral artery (5; 20%).
Conclusions
Performing an endomyocardial biopsy and coronary angiography through a single arterial access is as effective and safe as with double access, arterial and additional venous. Procedure time and fluoroscopic time is significantly less when it is performed through the same access.

Abstract
Abstract
Introduction
Infective endocarditis (IE) is a potentially serious complication in patients with prosthetic heart valves. The objective of this study is to analyze and describe the incidence, baseline characteristics, risks factors and in-hospital evolution in IE after Transcatheter Aortic Valve Implantation (IE-TAVI).
Methods
All the TAVI implanted in our center since the beginning of the program have been included consecutively. Patients with a confirmed diagnosis of IE according to the “ESC Guidelines for the management of infective endocarditis” are identified and analyzed.
Results
331 TAVI have been implanted in our center from June 2009 to February 2021. IE-TAVI incidence in our series is 2.7% (n=9 cases). In baseline analysis, we observed that insulin dependent diabetes mellitus, Barthel Score and Pulmonary systolic pressure >50mmHg are significantly associated with the appearance of IE-TAVI (TABLE 1).
The most frequently microorganism is Enterococcus faecalis (44.4%; n=4) followed by Staphylococcus aureus (22.2%; n=2), Coagulase-negative staphylococci (22.2%; n=2) and Streptococcus viridans (11.1%; n=1).
77.8% of IE-TAVI (n=7) are Nosocomial IE or non-nosocomial healthcare-associated IE. 2 of them have been related to implantation (1 Enterococcus faecalis and 1 Coagulase-negative staphylococci) and 5 have been related to other interventions (2 after gastroscopy, 1 after percutaneous vascular intervention, 1 hemodialysis catheter infection and 2 unknown focus).
44.4% of IE-TAVI (n=4) were confirmed after performing Positron Emission Tomography (PET) scan. 3 cases (33.3%) were diagnosed with the initial Transthoracic Echocardiogram (TTE) and 2 cases (22.2%) were diagnosed after performing a Transesophageal Echocardiogram (TEE) (TABLE 2)
4 patients had an indication for surgery according to the ESC Guidelines (3 for persistent bacteremia and 1 for severe aortic regurgitation), but all were ruled out due to high surgical risk. Hospital mortality was 44.4% (n=4). The main predictor of hospital mortality was having an indication for surgery (p=0.028), which was present in 3 of the 4 deaths. The other death was due to digestive bleeding during hospitalization.
Conclusions
IE-TAVI is a serious disease with high in-hospital mortality. Insulin dependent diabetes mellitus, Barthel Score and Pulmonary systolic pressure >50mmHg are risk factors for IE-TAVI. PET-scan is the imaging test of choice when there were no echocardiographic findings. The main predictor of mortality is having an indication for surgery according to the ESC Guidelines.

Impact of transcatheter aortic valve replacement on anemia: new approach to Heyde's syndrome. Eur Heart J 2020.

Abstract
Abstract
Background
There is an association between aortic stenosis and anaemia known as Heyde's syndrome. It is caused by an acquired von Willebrand (VW) deficiency related to turbulent flow. Patients with significant paravalvular leak (SPL) remain with VW deficit. The aim of this work is to assess impact on prognosis and anaemia of SPL.
Methods
Observational analytic study developed at two university hospitals, including all consecutive patients who underwent TAVI during a 10-year period (2009 to 2018). A logistic regression model was created to determine independent predictors of anaemia at 3 months. Time to event outcomes were analysed with Cox regression. Median follow-up was 21.3±21.9 months.
Results
5.3% of 788 patients had SPL, with no differences on their basal characteristics compared to the rest of the cohort. SPL was an independent predictor of anaemia 3 months after TAVI (Odds Ratio: 8.31, Confidence Interval 95% [CI]: 2.06–33.50).
SPL had negative impact on mortality: Hazard Ratio (HR): 1.85, CI 1.2–2.9; but not on cardiovascular mortality (CV): HR 1.13, CI 0.4–3.1. Patients who had anaemia three months after TAVI had an increased mortality. (HR 2.17, CI 1.5–3.3)
Conclusion
SPL after TAVI increases mortality with no impact on CV mortality. SPL is independent predictor of anaemia 3 months after TAVI, a condition that doubles the mortality. The impact of SPL on mortality could be explained by the increase in anaemia that SPL causes. More aggressive approach to SPL could have a benefit on prognosis.
