Transapical Left Ventricular Bypass
Chest, 1971To the Editor.—Good people often reinvent a procedure that has already been invented, when there is a need for it and when the times are ripe for it. This is true for the procedure described by Dr. John C. Norman,1and also described by Drs. J. Kent Trinkle and Lester R. Bryant.2To the best of our knowledge, Dr.

Transapical neochord implantation
Multimedia Manual of Cardio-Thoracic Surgery, 2011The neo-chord procedure was introduced to facilitate chordal replacement for mitral valve repair using a transapical beating heart off-pump approach. This tutorial describes the concept, the technique, the operative approach, and the procedure in a step-by-step manner.

Transapical Sutures in Dinoflagellate Cysts
Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1972Abstract Several lacustrine species of Pleistocene and Recent peridiniacean cysts form archeopyles by means of a single transapical suture, with or without accessory sutures. Previously published records of closely similar structures in marine Cretaceous peridiniacean cysts are documented and reinterpreted, and a further type is described from the ...

TAVI: transapical - what else?
EuroIntervention, 2013Transcatheter aortic valve implantation is a relatively new technique to treat elderly and high-risk patients with aortic stenosis using a retrograde transfemoral, transsubclavian, transaortic or an antegrade transapical approach. TAVI procedures can be divided into two parts: the access to the cardiovascular system, and valve positioning and ...

Transapical Aortic Cannulation in Pediatric Patients
The Annals of Thoracic Surgery, 1997We describe transapical aortic cannulation in pediatric patients. This technique may help to establish cardiopulmonary bypass in small children in whom aortic root cannulation is undesirable or not feasible.

Transcatheter and Transapical Aortic Valve Replacement
Critical Care Nurse, 2009Minimally invasive valve replacement is limited to bioprosthetic aortic and pulmonary valves for use in very specific populations of patients. Replacement via trans-catheter and transapical techniques should be used only in patients in whom traditional surgical replacement is deemed an unacceptable risk.

Transapical Mitral Valved Stent Implantation
The Annals of Thoracic Surgery, 2008Transcatheter aortic and pulmonary valve replacement is currently being tested in human trials. Efforts to create a valved stent to replace the atrioventricular valves have shown limited success. This is due to their their complex anatomy and function.A self-expanding valved stent was created for transapical replacement of the atrioventricular valve ...

Innovations: Technology and Techniques in Cardiothoracic and Vascular Surgery, 2019
One-third of the patients with severe symptomatic aortic valve stenosis (sAS) present with hemodynamic relevant mitral valve insufficiency (rMI). In patients who undergo conventional surgery, the rMI never would be left untreated; however, in cases of transcatheter aortic valve implantation (TAVI), the impact of rMI is often overlooked and left ...

Transapical approach in transcatheter cardiovascular interventions
General Thoracic and Cardiovascular Surgery, 2018The left ventricular apex has excellent accessibility to the aortic valve, mitral valve, left ventricular outflow tract and thoracic aorta. Although the number of transapical approach in transcatheter aortic valve replacement has been decreasing in recent years, it is still a useful option for patients with very poor peripheral vascular access.

The Annals of Thoracic Surgery, 2013
Transapical transcatheter aortic valve implantation (TA-TAVI) is the method of choice in patients with severe stenosis of the aortic valve, high operative risk, and an adverse peripheral vasculature. The procedure is generally guided by peripheral arterial access angiography.
