Abstract Background We present a complex case of a failing tricuspid mechanical valve prosthesis in a patient with refractory cardiogenic shock at prohibitive risk for surgery in whom balloon ‘valvuloplasty’ resulted in immediate haemodynamic improvement in valve function. Case summary A 67-year-old woman with remote history of endocarditis s/p tricuspid valve repair and mechanical aortic valve replacement was referred for second opinion and management of new severe symptomatic tricuspid valve stenosis resulting in progressive debilitating congestive heart failure (HF). The patient was approved by the heart team to undergo redo open heart for surgical repair of the tricuspid valve. Intraoperative technical challenges were met to repair the tricuspid valve. In turn, the native valve was resected and a 33 mm On-X mechanical valve prosthesis. The patient’s post-operative course was complicated by recurrent haemoptysis, prolonged mechanical respiratory support, acute kidney injury, and cardiogenic shock. Surgical re-exploration to address the dysfunctional mechanical tricuspid valve was felt to be prohibitive. Structural heart team was consulted. Cardiac catheterization was recommended to ascertain and confirm findings. The patient was transferred to the cardiac catheterization laboratory. Initial fluoroscopic examination of the heart confirmed the echocardiographic results of an immobile septal leaflet of the recently implanted mechanical tricuspid valve. An 8 × 40 mm Mustang OTW angioplasty balloon was then advanced across the mechanical valve and inflated gradually at nominal pressure. A single inflation resulted in successful restoration of valve leaflet function. Discussion To the best of our knowledge, this is the first balloon ‘valvuloplasty’ on a mechanical On-X valve in the tricuspid position.

The article presents the results of the assessment of 52 patients' quality of life that had tricuspid valve prosthesis at the age from 1 to 16 years. Quality of life was evaluated by using a Nottingham Health Profile questionnaire. The data obtained suggests that quality of life in patients with tricuspid valve prosthesis is lower; it depends on the type of the operation performed, functional classes of cardiac decompensation and exercise tolerance. Besides, it is directly correlated with the right heart and BNP level.

Abstract Background Tricuspid valve (TV) stenosis is a very rare condition and the aetiology is primarily due to rheumatic disease, carcinoid disease, congenital heart disease, endocarditis, and following degeneration of biological valve prosthesis. Case summary We present a 45-year-old man with a rare case of symptomatic TV stenosis (TS) in a previously isolated TV repair. A meticulous multimodality diagnostic approach is presented in order to determine the severity of the TS and to evaluate the right ventricular function. Discussion This case report presents an integrated multimodality imaging and haemodynamic approach to evaluate and document the suspicion of development of a symptomatic significant stenosis in a previous TV repair. The initial TV repair was done without ring annuloplasty, because only the anterior leaflet was affected and bicuspidalization of the valve made it patent. In addition, minimizing the amount of implanted material was intended to minimize the risk of reinfection. The final treatment was performed as a TV replacement with insertion of a bioprosthesis.

Background In patients with remarkably enlarged cardiac chambers and history of implantation of older types of mitral valve prosthesis, the considerations for reoperative tricuspid valve surgery are not limited to the risks of sternal reentry but also include the dilemma of whether to carry out prophylactic replacement of the normal functioning but outdated prosthesis or leave it in situ. Methods We reviewed our surgical strategy and postoperative 5-year follow-up findings in two patients who underwent redo tricuspid surgery 3 to 4 decades after mechanical mitral valve replacement. Both patients presented with significant symptoms of progressive right heart failure due to severe tricuspid regurgitation, despite optimal medical therapy. Results We found the beating-heart approach to be an effective and safe method for redo tricuspid surgery. Both first-generation mitral mechanical prostheses were not replaced and have remained well functional upon the patients’ postoperative 5-year follow-up, respectively. Conclusion For patients with normal functioning first-generation mechanical mitral prostheses, whether to prophylactically replace the prosthesis should be based on an individualized risk-benefit analysis.
