Litoplastía iliaco-femoral para implante transcatéter de válvula órtica / Iliac-femoral lithoplasty for a transcatheter aortic valve implantation. Report of one case

Transcatheter aortic valve implantation (TAVI) has a lower perioperative risk than traditional surgery mostly when the transfemoral access is used. Some patients have anatomical conditions that contraindicate the use of this route. Lithoplasty is a novel technique that fractures calcium in coronary and peripheral arteries using pulsatile waves transmitted through an angioplasty balloon. We report an 83 year-old male with an aortic stenosis requiring TAVI, with severe calcification of his femoral and aortic arteries. A balloon lithoplasty of the right iliac-femoral tract was carried out, which allowed the use of the transfemoral route to install the aortic prosthesis. The patient had a good subsequent evolution.

ECMELLA: Uso combinado de dispositivos de asistencia ventricular izquierda en el manejo del shock cardiogénico postinfarto agudo al miocardio / Combined use of left ventricular assist devices in cardiogenic shock. Report of one case

We report a 55-year-old woman with a history of hypothyroidism and type 2 diabetes mellitus who consulted at the emergency room because of intermittent oppressive chest discomfort. At admission, electrocardiogram showed a complete atrioventricular block. A transthoracic echocardiogram disclosed severe left ventricular dysfunction. The patient developed cardiogenic shock that required the installation of the Impella system. An emergency coronary angiography showed an ostial occlusion of the anterior descending artery. Despite successful primary angioplasty, she persisted with refractory shock and progressive hypoxemia. A concomitant connection to the extracorporeal membrane oxygenation system (ECMO) was decided. The support of both devices allowed the stabilization of the patient and the improvement of perfusion parameters.

Implante percutáneo de válvula aórtica transcatéter por vía femoral en paciente joven con obesidad extrema / Trans femoral TAVI in extremely obese patient with severe aortic stenosis

RESUMEN:TAVI transfemoral en una paciente con obesidad extrema y estenosis aórtica severa. Una mujer extremadamente obesa (IMC 62.5 Kg/M2) con estenosis aórtica severa fue descartada para cirugía bariátrica y reemplazo valvular aórtico. Se efectuó una TAVI por vía transfemoral, sin anestesia general. Se describen cuidadosas técnicas para efectuar la punción femoral y su sellado posterior. La paciente se recuperó sin incidentes, la gradiente transvalvular aórtica se redujo significativamente y hubo mínima insuficiencia valvular.

ABSTRACT: An extremely obese woman (BMI 62.5 Kg/M2) with severe symptomatic aortic stenosis was discarded for bariatric surgery or aortic valve replacement. A transfemoral TAVI was performed, without general anesthesia. Careful techniques to perform and seal the transfemoral puncture are described. The patient recovered uneventfully with a significant decrease in aortic valve gradient and minimal aortic insufficiency.

Implante concomitante de MitraClip y cierre de orejuela izquierda: importancia de la puncoón transeptal y sus implicancias técnicas: caso clínico / Concomitant deployment of MitraClip devices and left atrial appendage closure: report of one case

We report a 65-years old woman with a history of permanent atrial fibrillation with high risk for ischemic and bleeding events. She developed a heart failure with severely impaired left ventricular ejection fraction and severe secondary mitral regurgitation. Given her high surgical risk, using transesophageal echocardiography guidance, a concomitant deployment of two MitraClip devices using a high-posterior septal puncture and a left atrial appendage closure with an Amplatzer Amulet occluder were performed through the same access.
