Left Bundle Branch Block after Transcatheter Aortic Valve Implantation with Edwards Sapien 3 Valve: Influence of the Valve Depth Implantation.

Cardiovasc Revasc Med 2019 Nov 9;20(11):949-955. Epub 2019 Jan 9.

Clinical Cardiology, Hospital Universitario HM Montepríncipe, Spain.

Objectives: The aim of this study is to determine the relation between the valve depth implantation and the new-onset left bundle branch block (LBBB) in patients treated with transcatheter aortic valve implantation (TAVI) using Edwards Sapien 3 (S3) prosthesis.

Background: LBBB is the most common conduction disturbance after TAVI. The S3 has been associated with a higher incidence of LBBB. A deep valve implant could be related to new-onset LBBB with S3.

Methods: Seventy-six consecutive patients treated with transfemoral TAVI with S3 were included. Electrocardiogram (ECG) registries were recorded at baseline, after the procedure, and before discharge. Valve depth implantation was determined in 40 patients by off-line analysis of the two/three-dimensional transeophageal echocardiogram (TEE) images, with measure of the valve stent percentage under the aortic annulus. Previous and new conduction anomalies were documented; and patient, anatomic and procedural characteristics were retrospectively analyzed.

Results: Complete atrioventricular block (AVB) incidence was 2.9%. LBBB after TAVI appeared in 39% of patients, being transient in almost half of the cases (permanent LBBB rate 20%). Patients with new-onset LBBB after TAVI were older, with a higher STS Score and a wider basal QRS. A deep valve position was associated with new-onset LBBB, with a ROC curve establishing a cut-off point of 34% of depth implant as risk factor for new-onset LBBB (sensitivity and specificity 0.8).

Conclusions: In transfemoral TAVI with S3 prosthesis, a higher valve implantation (<34% of valve stent introduced into the ventricle) may minimize the new-onset LBBB, especially in old and high-risk patients with a wide basal QRS.

Electrocardiographic changes and conduction disturbances after transfemoral aortic valve implantation with Edwards Sapien 3 prosthesis.

J Electrocardiol 2018 May - Jun;51(3):416-421. Epub 2018 Feb 20.

Clinical Cardiology Department, Hospital Universitario HM Montepríncipe, Madrid, Spain.

Objectives: The aim of this study is to describe electrocardiographic changes and conduction abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI).

Methods: 76 patients who underwent TAVI using Edwards Sapien 3 prosthesis were included, comparing electrocardiographic registries at admission, post-procedure and before discharge.

Results: Patients after TAVI presented a longer PR interval, a wider QRS, and a longer corrected QT, with a left deviation of QRS axis and T waves; reversible changes that tended to correct in the following days after TAVI. Complete atrioventricular block incidence was 2.9%. New-onset left bundle branch block (LBBB) incidence was 39%, although solved in almost half of patients before discharge.

Conclusions: TAVI was associated with different reversible electrocardiographic changes that suggest a transient impact on the conduction system. One of every five patients presented permanent LBBB after valve implant.

Placement of a single Axxess stent as new treatment strategy for Medina 1,0,0 left main stem bifurcation lesion.

J Invasive Cardiol 2014 Apr;26(4):E45-7

Hospital Universitario Madrid Montepríncipe, Madrid, Spain.

A left main stem bifurcation lesion (Medina 1,0,0) treated with a single Axxess stent through radial access is presented. Although the use of this stent in left main stenosis is off label, in selected cases it may simplify the technique, avoiding the use of additional overlapping stents and ensuring the bifurcation coverage with minimal amount of metal at the carina.

Coronary lesions quantification with dual-axis rotational coronary angiography.

Cardiovasc Revasc Med 2013 Jan-Feb;14(1):37-40. Epub 2012 Dec 5.

Hospital Universitario Madrid Montepríncipe, Avda. de Montepríncipe 25, 28660 Boadilla del Monte, Madrid, España.

Background: Coronary angiography (CA) has been the gold standard technique for studying coronary artery disease. It is based on the analysis of bidimensional orthogonal projections that may not be optimal to estimate determinate coronary segments. Rotational angiography "Xperswing" (DARCA) is a new technique that allows the visualization of the coronary arteries from multiple views, with a single contrast injection. The aim of this study is to evaluate the coronary lesions quantification with DARCA.

Methods: Quantitative coronary analysis of significant coronary stenosis (>50%) was performed. Every lesion was measured in two different projections: the "optimal projection", obtained by DARCA and defined by the operator as the one with a better lesion qualification, and the "standard projection", corresponding to the usual projection closer to the optimal one in obliquity and angulation. Measures were performed twice and by two independent operators. Intra- and inter-observer correlation was estimated by Kappa index and variables were compared with t Student test (SPSS 14.0).

Results: 205 lesions in 147 patients were analyzed. Kappa coefficient intra-observer was 0.80 and 0.86 respectively with an inter-observer correlation index of 0.72. Lesion length and maximal diameter of the vessel were significantly greater in the group of RA. In the segments analysis, calculated length was longer for the first diagonal branch, first marginal obtuse artery, middle circumflex, middle and distal RCA and posterior descending artery, with greater reference diameters for proximal LAD and distal RCA. There were no significant differences for coronary stenosis grade.

Conclusions: RA XperSwing provides a better visualization of coronary arteries improving lesions characterization, with longer measured lesions length and greater vessel diameters, especially in coronary segments with more angulation.
