degenerative Pulmonary Valve Insufficiency in a patient with a prior bentall procedure
The Annals of Thoracic Surgery, 2021Co-Authors: Austen Hufton, Joshua S Newman, Stevan S Pupovac, Allan Mattia, Alan R HartmanAbstract:Adult Pulmonary Valve regurgitation most commonly presents after congenital cardiac surgery, with limited reports of pure degenerative valvular disease. We present a patient who underwent a Bentall procedure for annuloaortic ectasia with severe aortic Insufficiency 14 years prior now presenting with degenerative, severe, symptomatic Pulmonary Valve regurgitation and normal Pulmonary pressures. The patient underwent successful Valve replacement with a bovine prosthesis. Recovery was unremarkable, and he continues to do well without further cardiac surgical requirements.

The Annals of Thoracic Surgery, 2020Co-Authors: Austen Hufton, Joshua S Newman, Stevan S Pupovac, Allan Mattia, Alan HartmanAbstract:Abstract Adult Pulmonary Valve regurgitation most commonly presents following congenital cardiac surgery, with limited reports of pure degenerative valvular disease. There is to our knowledge, no documented reports of a patient with idiopathic symptomatic degenerative Pulmonary Valve regurgitation and normal Pulmonary arterial pressures. We present a patient who underwent a Bentall procedure for annuloaortic ectasia with severe aortic Insufficiency 14 years prior now presenting with degenerative severe symptomatic Pulmonary Valve regurgitation and normal Pulmonary pressures. The patient underwent successful Valve replacement with a bovine prosthesis. Recovery was unremarkable, and he continues to do well without further cardiac surgical requirements.

relief of branch Pulmonary artery stenosis reduces Pulmonary Valve Insufficiency in a swine model
The Journal of Thoracic and Cardiovascular Surgery, 2009Co-Authors: Christopher J Petit, Matthew A. Harris, Matthew J Gillespie, Travis L Seymour, Timothy Y Liu, Azeem R Khan, William J Gaynor, Jonathan J RomeAbstract:Objective We sought to determine the impact of relieving branch Pulmonary artery stenosis on Pulmonary Valve Insufficiency and right ventricular function. Long-standing Pulmonary Insufficiency causes progressive right ventricular dilatation, leading to decreased right ventricular function. Adults with Pulmonary Insufficiency are at risk of decreased exercise tolerance, arrhythmias, and sudden cardiac death. Branch Pulmonary artery stenosis frequently occurs in these patients, and the presence of branch stenosis may exacerbate Valve Insufficiency. Methods Neonatal piglets (n = 7) underwent surgery to create Pulmonary Insufficiency and left Pulmonary artery stenosis. At 3 months of age, the animals underwent baseline cardiac magnetic resonance imaging followed by stenting of the left Pulmonary artery. A repeat magnetic resonance imaging scan was performed 1 week after intervention. Magnetic resonance imaging evaluation included (1) velocity mapping to assess the forward and reverse flow at the main, left and right Pulmonary arteries, and aorta; and (2) volumetric assessment of the right ventricle. Results Left Pulmonary artery flow increased from 14.5% to 36.3% of total net flow after stenting ( P P P 2 ( P = .01). Conclusion Relief of branch Pulmonary artery stenosis reduces Insufficiency and improves right ventricular systolic function in this animal model. This supports the practice of aggressive intervention in patients with branch Pulmonary artery stenosis and Pulmonary Insufficiency.

left coronary artery occlusion after percutaneous Pulmonary Valve implantation
The Annals of Thoracic Surgery, 2012Co-Authors: D Biermann, Jeanette Schonebeck, Marcus Rebel, Jochen Weil, Ali DodgekhatamiAbstract:Percutaneous Pulmonary Valve implantation (PPVI) is an attractive option for patients with Pulmonary Valve Insufficiency or stenotic right ventricular outflow tracts. We present the case of a 26-year-old patient in which PPVI was used to treat d-transposition of the great arteries, uncommon coronary artery anatomy, and conduit stenosis that resulted from multiple operations on the right outflow. Days after discharge to home, she experienced acute chest discomfort correlating with ischemia noted on an electrocardiogram and elevated troponin levels. Coronary angiography confirmed mechanical compression of the left anterior descending coronary artery. The Valve was removed in an emergency operation and replaced with a biological conduit.

chronic Pulmonary Valve Insufficiency after repaired tetralogy of fallot diagnostics reoperations and reconstruction possibilities
Expert Review of Cardiovascular Therapy, 2007Co-Authors: Alexander Kadner, Igor I Tulevski, Urs Bauersfeld, Rene Pretre, Emanuela R Valsangiacomobuechel, Ali DodgekhatamiAbstract:Complete correction of Tetralogy of Fallot, the most common cyanotic congenital heart defect, has now become routine. However, late residual lesions, primarily chronic Pulmonary Valve Insufficiency, may have a negative impact on right-ventricular function, leading to the need for reoperation to insert a competent Valve at the right-ventricular outflow. The diagnostic modalities pertaining to the failing right ventricle, the timing for eventual reintervention and the various surgical reconstruction possibilities of the right-ventricular outflow tract are still controversial and evolving, and are reviewed with a brief overview on current trends and future outlooks.

comparative long term results of surgery versus balloon valvuloplasty for Pulmonary Valve stenosis in infants and children
The Annals of Thoracic Surgery, 2003Co-Authors: Claire Peterson, Johanneke J Schilthuis, Ali Dodgekhatami, Francois J Hitchcock, Erik J Meijboom, G B W E BenninkAbstract:Abstract Background We compared the long-term results of surgical valvotomy (S) versus balloon valvuloplasty (BV) for Pulmonary Valve stenosis in infants and children. Methods Results after surgical Pulmonary valvotomy (with concomitant ASD/VSD closure) (n = 62, age 2.9 ± 3.5 years) and balloon valvuloplasty (n = 108, age 3.6 ± 3.9 years) were analyzed. Transvalvular mean pressure gradient decrease, freedom from reintervention for restenosis, Pulmonary Valve Insufficiency, and tricuspid Valve Insufficiency were considered. Results Mean pressure gradient decreased significantly more in the surgical group (from 64.8 ± 30.8 mm Hg to 12.8 ± 9.8 mm Hg at a mean follow-up of 9.8 years) than after BV (decreasing from 66.2 ± 21.4 mm Hg to 21.5 ± 15.9 mm Hg after a mean of 5.4 years; p p p Conclusions Surgical relief of Pulmonary Valve stenosis produces lower long-term gradients and results in longer freedom from reintervention. Balloon valvuloplasty may remain, despite these results, the preferred therapy for isolated Pulmonary Valve stenosis, because it is less invasive, less expensive, and requires a shorter hospital stay. Surgery should remain the exclusive form of therapy in the presence of concomitant intracardiac defects, which need to be addressed.
