An unusual cause of acute mitral regurgitation in TTK Chitra Heart Valve Prosthesis
Indian Journal of Thoracic and Cardiovascular Surgery, 2021Co-Authors: Muthukumar Sundaram, Aayush Poddar, Ancy Robinson, Soundaravalli Balakrishnan, Muralidharan Srinivasan, Chandrasekar PadmanabhanAbstract:Structural failure of mechanical Heart Valve was a known feature when it was evolving in the 1960s and 1970s. With the advent of pyrolytic carbon and a better design, it is a rare entity with present Valves. We report a case of disc fracture leading to acute mitral regurgitation in TTK Chitra Heart Valve Prosthesis (CHVP) (TTK Healthcare Limited, India) Heart Valve, 6 years after its implantation in mitral position.

Hemodynamic performance evaluation of TTK Chitra Heart Valve Prosthesis in the aortic position using Doppler echocardiography.
International journal of cardiology, 2008Co-Authors: Narayanan Namboodiri, Othayoth Shajeem, Jaganmohan Tharakan, R. Sankarkumar, Thomas Titus, Valaparambil K. Ajitkumar, Sivasubramonian Sivasankaran, Kavassery Mahadevan Krishnamoorthy, S. HarikrishnanAbstract:More than 15,000 patients have been implanted with TTK Chitra Heart Valve Prosthesis (CHVP), a tilting disc prosthetic Valve in various institutions in India. Though it has been in use for more than 15 years with a few follow up studies reporting excellent long term clinical results [1–3], there is scarcity of data on the normal echocardiographic parameters of this Valve. This study was planned to establish a reference for the normal Doppler echocardiographic parameters for the CHVP in aortic position with the use of transthoracic echocardiography (TTE), in a large series of patients with normally functioning Valves.

Karl Viktor Hall: From In Situ Vein Bypass to the Tilting Disc Heart Valve Prosthesis
The Annals of thoracic surgery, 2016Co-Authors: John-peder Escobar Kvitting, Odd GeiranAbstract:In 1977, Karl Viktor Hall implanted a novel tilting disc Heart Valve Prosthesis at Rikshospitalet in Oslo, Norway. The Medtronic-Hall Valve was known for its excellent durability and low thrombogenicity. Hall popularized the use of the great saphenous vein in situ as an arterial shunt in the 1960s, made a metal stripper to lyse vein Valves, and introduced electromagnetic flowmeters in vascular surgery. He performed the first coronary artery bypass graft in Scandinavia in 1969. Under his leadership the first Heart transplantation and the first Heart-lung transplantation were performed in Scandinavia by his successor Tor Froysaker in 1983 and 1986, respectively.
