Real-time MRI guided percutaneous transthoracic left ventricular access and closure
Methods Sixteen Yorkshire swine underwent percutaneous transthoracic LV access and followed up to three months (n=8). All procedures were guided by real-time bSSFP MRI (Espree, Siemens) using two slices along the needle trajectory and a short-axis slice for cardiac monitoring. Transthoracic ventricular puncture was performed using a customized 18G active needle with integrated loop coil. Punctu...
متن کاملPercutaneous closure of left ventricular pseudoaneurysm.
The risk of rupture of a left ventricular (LV) pseudoaneurysm ranges from 30% to 45% in the first year. Open surgical repair carries high mortality related to anatomic complexity and patient comorbidities. Percutaneous closure may offer a viable alternative to surgical intervention in this cohort. Herein, we describe 3 unique cases of transcatheter LV pseudoaneurysm closure.
متن کاملPercutaneous Closure of Left Ventricular Pseudoaneurysm
Background—Left ventricular pseudoaneurysm is a rare but serious complication from myocardial infarction and cardiac surgery. Although standard treatment is surgical intervention, percutaneous closure of left ventricular pseudoaneurysm has become an option for high-risk surgical candidates. Experience with percutaneous treatment is limited to a few single case reports. This is the first series ...
متن کاملDirect percutaneous left ventricular access and port closure: pre-clinical feasibility.
OBJECTIVES This study sought to evaluate feasibility of nonsurgical transthoracic catheter-based left ventricular (LV) access and closure. BACKGROUND Implanting large devices, such as mitral or aortic valve prostheses, into the heart requires surgical exposure and repair. Reliable percutaneous direct transthoracic LV access and closure would allow new nonsurgical therapeutic procedures. MET...
متن کاملFully percutaneous transthoracic left atrial entry and closure as a potential access route for transcatheter mitral valve interventions.
BACKGROUND Percutaneous access for mitral interventions is currently limited to transapical and transseptal routes, both of which have shortcomings. We hypothesized that the left atrium could be accessed directly through the posterior chest wall under imaging guidance. METHODS AND RESULTS We tested percutaneous transthoracic left atrial access in 12 animals (10 pigs and 2 sheep) under real-ti...
