Percutaneous treatment of a splenorenal shunt with an atrial septal closure device.

We present the case of a 70-year-old female who underwent liver transplantation in 2011 due to enolic cirrhosis with a normofunction graft and no portal hypertension. During the last months, recurrent hospitalization was needed due to hepatic encephalopathy, in spite of treatment with lactulose and rifaximin. An abdominal computed tomography (CT) showed a large varicose dilatation of the splenic vein up to 14-16 mm, descending by the left abdominal side, communicating with the renal vein with direct drainage into inferior cava vein (ICV).

Percutaneous treatment of an early complication after endocarditis surgery with Cabrol type repair.

We present a 70-year-old man with rheumatic mitral valve disease who had undergone 3 previous open-heart surgeries, the last of which was a new mitral valve replacement for a mechanical prosthesis due to early bioprosthetic endocarditis.

Early clinical outcomes after transaxillary versus transfemoral TAVI. Data from the Spanish TAVI registry.

INTRODUCTION AND OBJECTIVES: Transaxillary access (TXA) has become the most widely used alternative to transfemoral access (TFA) in patients undergoing transcatheter aortic valve implantation (TAVI). The aim of this study was to compare total in-hospital and 30-day mortality in patients included in the Spanish TAVI registry who were treated by TXA or TFA access. METHODS: We analyzed data from patients treated with TXA or TFA and who were included in the TAVI Spanish registry. In-hospital and 30-day events were defined according to the recommendations of the Valve Academic Research Consortium. The impact of the access route was evaluated by propensity score matching according to clinical and echocardiogram characteristics. RESULTS: A total of 6603 patients were included; 191 (2.9%) were treated via TXA and 6412 via TFA access. After adjustment (n=113 TXA group and n=3035 TFA group) device success was similar between the 2 groups (94%, TXA vs 95%, TFA; P=.95). However, compared with the TFA group, the TXA group showed a higher rate of acute myocardial infarction (OR, 5.3; 95%CI, 2.0-13.8); P=.001), renal complications (OR, 2.3; 95%CI, 1.3-4.1; P=.003), and pacemaker implantation (OR, 1.6; 95%CI, 1.01-2.6; P=.03). The TXA group also had higher in-hospital and 30-day mortality rates (OR, 2.2; 95%CI, 1.04-4.6; P=.039 and OR, 2.3; 95%CI, 1.2-4.5; P=.01, respectively). CONCLUSIONS: Compared with ATF, TXA is associated with higher total mortality, both in-hospital and at 30 days. Given these results, we believe that TXA should be considered only in those patients who are not suitable candidates for TFA.

Spanish registry of percutaneous VSD closure with NitOcclud Lê VSD Coil device: lessons learned after more than a hundred implants.

INTRODUCTION AND OBJECTIVES: The NitOcclud Lê VSD Coil was specifically designed for transcatheter occlusion of ventricular septal defects (VSD) and became available for this purpose in August 2010. Our objective was to describe the Spanish experience of this technique and analyze its reliability and short- to mid-term efficacy. METHODS: National multicenter observational study, which retrospectively recruited all patients (of any age) with VSD (of any location or type) who underwent percutaneous NitOcclud occlusion, using an intention-to-treat analysis, until January 2019. RESULTS: A total of 117 attempts were made to implant at least 1 NitOcclud in 116 patients in 13 institutions. The median [range] age and weight was 8.6 [0.4-69] years and 27 [5.8-97] kg, respectively. In 99 patients (85%), the VSD was an isolated congenital defect. The location was perimembranous in 95 (81%), and 74 (63%) of them were aneurysmatic. The mean fluoroscopy time was 34 [11.4-124] minutes. Of the 117 attempts, 104 were successful (89%) with a follow-up of 31.4 [0.6-59] months. At the last review, final complete occlusion of the defect without residual shunt or with only a minimal shunt was achieved in 92.3% (no shunt, n=73; trivial shunt, n=23). Four patients required a second procedure for residual shunt occlusion. Two devices had to be surgically explanted due to severe hemolysis. There were no deaths or other major complications. CONCLUSIONS: The NitOcclud device can be used successfully for a wide anatomical spectrum of VSD. The main issue is residual shunt, but its incidence decreases over time. The incidence of hemolysis was very low and no permanent changes were detected in atrioventricular conduction.

Experiencia en angioplastia percutánea de recoartación de aorta en un solo centro. Resultados a corto, medio y largo plazo / Experience in percutaneous angioplasty of aortic recoartation in a single centre. Short, medium and long-term outcomes

Resumen Introducción: La angioplastia con balón es una técnica que ofrece buenos resultados, especialmente en los casos de recoartación tras cirugía correctora. Objetivo: Analizar los resultados de un centro hospitalario a partir de la introducción de la técnica. Método: Se analizaron 73 pacientes con una edad media de 3.3 años; el 74% eran menores de 1 año y el 72.6% estaban por debajo de 10 kg de peso. Todos los pacientes incluidos fueron casos de recoartación tras cirugía correctora. Resultados: Se observó un resultado efectivo en el 93.1% de los casos, con gradiente residual < 20 mmHg. Durante el seguimiento, el 20.5% precisaron reintervención, la cual fue más frecuente en caso de angioplastia sobre el arco, lesiones asociadas y menores de 1 año. Solo se objetivó una complicación grave relacionada con el procedimiento, que correspondió a una rotura aórtica que no pudo ser solventada con implante de stent cubierto. Conclusiones: La angioplastia percutánea de recoartación de aorta es una técnica segura y efectiva, en especial en los casos de recoartación tras cirugía correctora de lesiones circunscritas al istmo.

Abstract Introduction: Balloon angioplasty is a technique with good outcomes, specially in cases aortic recoartation after correcting surgery. Objective: To analyze our centre results since the introduction of the technique. Method: We analyzed 73 patients with medium age of 3,3 years; 74% were under 1 years old and 72,6% under 10 kg weight. All patients included were cases of recoartation after surgery. Results: Effective results was achieved in 93,1%, obtaining residual gradient less than 20 mmHg. During the following up 20,5% of patients required reintervention, being more frequent in case of aortic arch hypoplasia, associated lesions or patients under 1 year. Only a severe complication was referred, a case of aortic rupture that couldn’t be solved with a covered stent. Conclusions: Percutaneous angioplasty of aortic recoartation is a safe and effective technique, specially in discrete istmic lesions after correcting surgery.

Transcatheter aortic valve implantation in patients with small aortic annuli using a 20†mm balloon-expanding valve.

BACKGROUND: While transcatheter aortic valve implantation (TAVI) is established for treating high-operative risk surgical aortic valve replacement candidates, until recently the smallest transcatheter heart valve (THV) measured 23 mm, posing greater risk for annular rupture and THV failure in patients with aortic stenosis (AS) with small aortic annuli (≤20 mm). OBJECTIVES: In the setting of a multicentre registry, we report on the safety, efficacy and early clinical outcomes of the SAPIEN XT 20 mm balloon-expanding THV. RESULTS: Among TAVI 55 recipients (n=30 for native AS, n=25 for a valve-in-valve procedure (V-in-V)), median age and Society of Thoracic Surgeons score were 85 (81 to 87) years and 7.8 (4.7 to 12.4)%, respectively. Mean and minimum annular diameters were 19±1 and 17±2 mm, respectively, in native patients with AS, and 17±1 mm (internal diameter) in V-in-V recipients. Successful device implantation rate was 96%, with no procedural-related death. Overall in-hospital-30-day death, stroke and major bleeding rates were 5%, 2% and 9%, respectively. In native AS TAVI recipients, mean transaortic gradient decreased from 54±20 to 12±5 mm Hg (p<0.001), and from 45±17 to 24±8 mm Hg (p<0.001) in V-in-V recipients. Severe prosthesis-patient mismatch (PPM) rates were 10% and 48% in native AS and V-in-V TAVI recipients, respectively (p=0.03). Post-TAVI, the rate of moderate aortic regurgitation was 7% and 0% in native AS and V-in-V TAVI recipients, respectively. CONCLUSIONS: TAVI with the 20 mm SAPIEN XT THV appears safe and technically feasible, with acceptable short-term clinical outcomes and low rates of severe PPM in those with native AS.
