Effects of a 3D segmental prosthetic system for tricuspid valve annulus remodelling on the right coronary artery: a human cadaveric coronary angiography study.

Interact Cardiovasc Thorac Surg 2017 09;25(3):350-355

Legal Medicine Research Center, Legal Medicine Organization, Tehran, Iran.

Objectives: A prosthetic system to repair secondary tricuspid valve regurgitation was developed. The conceptual engineering of the current device is based on 3D segmental remodelling of the tricuspid valve annulus in lieu of reductive annuloplasty. This study was designed to investigate the operational safety of the current prosthetic system with regard to the anatomical integrity of the right coronary artery (RCA) in fresh cadaveric human hearts.

Methods: During the study period, from January to April 2016, the current prosthetic system was implanted on the tricuspid valve annulus in fresh cadaveric human hearts that met the study's inclusion criteria. The prepared specimens were investigated via selective coronary angiography of the RCA in the catheterization laboratory. The RCA angiographic anatomies were categorized as normal, distorted, kinked or occluded.

Results: Sixteen specimens underwent implantation of the current prosthetic system. The mean age of the cadaveric human hearts was 43.24 ± 15.79 years, with vehicle accident being the primary cause of death (59%). A dominant RCA was noticed in 62.5% of the specimens. None of the specimens displayed any injury, distortion, kinking or occlusion in the RCA due to the implantation of the prostheses.

Conclusions: In light of the results of the present study, undertaken on fresh cadaveric human heart specimens, the current segmental prosthetic system for 3D remodelling of the tricuspid valve annulus seems to be safe vis-à-vis the anatomical integrity of the RCA. Further in vivo studies are needed to investigate the functional features of the current prosthetic system with a view to addressing the complex pathophysiology of secondary tricuspid valve regurgitation.

Right-sided reverse T composite arterial grafting to complete revascularization of the right coronary artery.

Rev Bras Cir Cardiovasc 2014 Oct-Dec;29(4):657-62

Mashhad University of Medical Sciences, Mashhad, Iran.

Complete arterial revascularization for the right coronary artery is underused mainly due to technical issues. Herein we report on a new approach for complete arterial revascularization of arterial revascularization for the right coronary artery branches. Complete arterial revascularization for the right coronary artery revascularization was performed in 8 patients using a reverse T composite arterial graft. None of the patients suffered perioperative myocardial infarction. All patients underwent noninvasive coronary imaging, displaying an early patency rate of 100%. Complete arterial arterial revascularization for the right coronary artery revascularization using a reverse T graft offers a new paradigm with enhanced technical flexibility in performing all arterial myocardial complete revascularizations in selected patients.

Right atrial chemodectoma with atypical chest pain: a 6-year surgical follow-up.

Ann Thorac Surg 2008 Sep;86(3):1006-8

Cardiac Surgery Department, Shaheed Rajaei Cardiovascular Medical Center, Iran University of Medical Sciences, Tehran, Iran.

Paragangliomas are rare neoplasms of neural crest origin and arise from the chromaffin (pheochromocytomas) or chemoreceptor (chemodectomas) tissues. Patients with cardiac chemodectomas, hormonally inactive paragangliomas, may have chest pain or various obstructive or compressive symptoms, depending on the location of the tumor. We report the case of a right atrial chemodectoma causing atypical chest pain. The tumor was discovered at transthoracic echocardiography. Coronary angiography showed a vascular tumor fed by a branch of the circumflex artery. En bloc tumor resection was carried out under cardiopulmonary bypass, with an uneventful surgical course. After 6 years of follow-up, the patient remains asymptomatic and disease-free.

Pericardial sewing-cuff: an alternative surgical technique for full-root implantation of aortic allograft and pulmonary autograft.

Eur J Cardiothorac Surg 2005 Apr;27(4):720-1

Teheran University of Medical Science, Iman Khomeini Hospital, Cardiac Surgery and Thoracic Transplantation department, Teheran, Iran.

The following is a description of a modified technique for the reinforcement of proximal anastomosis regarding the process of aortic allograft or pulmonary autograft full root implantation. A double width pericardial strip is used to create a pericardial sewing-cuff to be used as a neo-ring. This technique is said to be best suited for decreasing the operative bleeding, reducing anastomotic pitfalls and concomitant repair of the aortic annulus.
