2 year follow up of the first in human transapical implantation of transcatheter inverted aortic Valve to treat native Mitral Valve Stenosis
Jacc-cardiovascular Interventions, 2015Co-Authors: Vaikom S Mahadevan, Imthiaz Manoly, Ragheb HasanAbstract:After our initial publication of the first in human transapical implantation of an inverted transcatheter (SAPIEN Valve, Edwards Lifesciences, Irvine, California) in the native Mitral position [(1)][1], we now report a 2-year clinical and echocardiographic follow-up with transesophageal

urgent resection of a giant left atrial appendage aneurysm and Mitral Valve replacement in a complex case of hurler scheie syndrome
Case Reports, 2015Co-Authors: Andrew Brazier, Petra Jenkins, Ragheb Hasan, Andreas HoschtitzkyAbstract:Hurler-Scheie syndrome is a rare lysosomal storage disease affecting the cardiovascular system. Besides the cardiac manifestations, it presents with complications from abnormal proteoglycan deposition in soft tissues in many locations, resulting in joint contractures, paraplegia, impaired vision, airway narrowing and restrictive lung function, to name a few. There are very few reports of surgical management of valvular heart disease due to mucopolysaccharidosis (MPS). We describe the successful management of a patient with an extremely challenging case of Mitral Valve Stenosis and a giant left atrial appendage aneurysm due to MPS type 1 (Hurler-Scheie syndrome). The patient underwent Mitral Valve replacement and excision of the giant left atrial appendage aneurysm; a similar case has not been previously reported.

first in human transapical implantation of an inverted transcatheter aortic Valve prosthesis to treat native Mitral Valve Stenosis
Circulation, 2013Co-Authors: Ragheb Hasan, Vaikom S Mahadevan, Heiko Schneider, Bernard ClarkeAbstract:Transcatheter aortic Valve implantation has become well established in the past decade. Its superiority in comparison with conventional surgical aortic Valve replacements in high-risk patients has been demonstrated in the Partner Cohort B trial.1 We report the first case of using an inverted transcatheter Edwards Sapien Valve (Edwards Lifesciences, CA) in the native Mitral Valve position, to treat severe calcific Mitral Stenosis. A 70-year-old woman was admitted to the intensive care unit after having had a cardiorespiratory collapse requiring ventilatory support. She was initially referred for assessment of worsening breathlessness, 7 years after coronary artery bypass grafting and aortic Valve replacement with a 21-mm Top Hat (Sulzer, Carbomedics, Austin, TX) Valve. Investigations in another center revealed patent grafts, severe calcific Mitral Stenosis with a Valve area of 0.9 cm2 and a mean gradient …

simultaneous transapical transcatheter aortic Valve replacement and transcatheter Mitral Valve replacement for native valvular Stenosis
Catheterization and Cardiovascular Interventions, 2016Co-Authors: Ali Elkharbotly, Augustin Delago, Mohammad ElhajjarAbstract:Transcatheter aortic Valve replacement (TAVR) is well established for patients who cannot undergo surgery (Leon et al., N Engl J Med 2010;363:1597) or are high risk for surgery (Smith et al., N Engl J Med 2011;364:2187-2198). Experience with the TAVR procedure has led to recent reports of successful transcatheter Mitral Valve replacement (TMVR) procedures (Cheung et al., J Am Coll Cardiol 2014;64:1814; Seiffert et al., J Am Coll Cardiol Interv 2012;5:341-349) separately or simultaneously with the TAVR. However, these reports were of simultaneous Valve-in-Valve procedures (Cheung Anson, et al. J Am Coll Cardiol 2013;61:1759-1766). A recent report from Portugal also reported simultaneous transpical implantation of an inverted transcatheter aortic Valve-in-ring in the Mitral position and transcatheter aortic Valve (Hasan et al., Circulation 2013;128:e74-e76). There has been an experience of TMVR only in native Mitral Valve for Mitral Valve Stenosis, but none in both aortic and Mitral Valves. We report the first in human case of simultaneous transapical TAVR and TMVR in native Valves secondary to valvular Stenosis. Our patient was not a candidate for percutaneous balloon Mitral valvuloplasty secondary to a high Wilkins Score. Sizing of the aortic Valve was based on the transesophageal echocardiogram (TEE), whereas sizing of the Mitral Valve was based on TEE measurements and balloon inflation during left ventriculography. © 2015 Wiley Periodicals, Inc.

native Mitral Stenosis treated with transcatheter Mitral Valve replacement
The Annals of Thoracic Surgery, 2016Co-Authors: Renuka Jain, Mohamed F Algahim, Tanvir Bajwa, Bijoy K Khandheria, Daniel OhairAbstract:Surgical treatment of Mitral Stenosis with extreme calcification remains a challenge. Recently, the balloon-expandable Valve prosthesis, anchored by radial force, offers a new option for these patients. We present 2 cases of transcatheter Mitral Valve replacement in patients with severe native Mitral Valve Stenosis and annular calcification deemed too extensive for conventional surgical techniques.
