Title: Innovations in Cardiac Surgery: The Contributions of Mark M. Dehdashtian

Introduction

Mark M. Dehdashtian, based in Irvine, California, is a prolific inventor with an impressive portfolio of 46 patents. His groundbreaking work in the field of cardiac surgery has led to innovative solutions for delivering prosthetic heart valves, greatly enhancing patient care and outcomes.

Latest Patents

Among Mark's latest innovations are two significant patents that focus on transapical and transaortic delivery systems for prosthetic heart valves. The first patent outlines a method of delivering a prosthetic heart valve to the aortic valve annulus while the patient's heart is still beating. The method involves accessing the left ventricle through an intercostal incision and forming a puncture in the left ventricle. A guidewire is then advanced into the left ventricle and through the native aortic valve, allowing for precise placement of the valve delivery device and ultimately expanding the prosthetic heart valve within the aortic valve annulus.

The second patent describes a delivery system and method for placing a prosthetic heart valve via a transaortic approach. This innovative system includes a balloon catheter designed to deliver a balloon-expandable prosthetic heart valve through an incision in the aorta. The flexible, tapered tip of the catheter aids in positioning the valve accurately within the aortic annulus, even over existing calcified leaflets, ensuring a minimally invasive procedure that can be tailored to patient needs.
