Problems solved by technology

Although the transapical approach has the advantage of avoiding cardiopulmonary bypass and also permits a shorter, straighter path to the mitral valve than an endovascular approach, it has been found that access through the left ventricle detracts from this critical function of the heart. severe trauma to the left atrium muscle compartment and can lead to long-term damage to the ejection fraction and / or can lead to the formation of scar tissue in the myocardium
Furthermore, controlling transapical bleeding during and after surgery is challenging due to hypertension in the left atrium, and the rate of bleeding-related complications is too high
Also, this approach requires pericardial access, which increases risk and complexity

Abstract

The invention provides systems, devices, and methods for performing catheter-based procedures in the heart. In specific embodiments a procedural catheter is introduced into the mediastinum from a suprasternal access site. The procedural catheter is passed through a wall of the heart, preferably at an extrapericardial location on the atrial dome. The procedural catheter is used to perform a procedure in the heart such as mitral valve repair or replacement, using remote catheter visualization techniques.

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 791,510, filed January 11, 2019, which is incorporated herein by reference. technical field [0003] The present invention generally relates to devices, systems and methods for performing catheter-based procedures on or in the heart, including but not limited to devices, systems and methods for performing catheter-based procedures on the left atrium and internal structures of the heart method. Background technique [0004] Heart disease has become the leading cause of death worldwide. Heart procedures such as cardiac surgery, cardiovascular surgery, and cardiothoracic surgery are important (and sometimes the only available) treatment options for many heart conditions. [0005] Traditionally, for heart surgery, open heart surgery is performed. Such procedures typically involve cutting and opening the patient's chest (eg, via a median sternotomy or thoracotomy, etc.)....
