Ramtin Cardiovascular Research and Treatment Center
Ramtin cardio-vascular research and treatment center, is a specialist cardio-vascular hospital located in Velenjak, northern Tehran, Iran. Professor Alireza Esmat, cardiovascular and cardiothoracic surgeon, has been performing open heart heart surgery at Ramtin since the hospital opened in 1995. With 80 beds, including 15 ICU beds and three operating theatres, the private hospital also runs a transplant research unit.
Owner and lead heart surgeon at Ramtin Hospital, Alireza Esmat is known for having performed the first tracheal stenosis operation in Iran, saving the life of the patient, a 27-year old female, and the only survivor of a car accident.
The surgical team, led by Professor Alireza Esmat, succeeded in employing a cartilage graft to enhance the tracheal luminal diameter where earlier investigators had revealed aggregation of fibrotic and granulation tissue at posterior aspect of the trachea at a length of 8-10cm.
Due to the linear extension of fibrosis, neither stenotic area resection nor end-end anastomosis were feasible while the implementation of synthetic material or metallic stent was also not possible. So, the surgical team innovated a new technique, employing a cartilage graft to enhance the tracheal luminal diameter. A 10cm length of the floating 12th rib was extracted, implemented at the anterior aspect of the trachea with interrupted nylon suturing to reconstruct the stenotic area.
Professor Alireza Esmat, who studied in Tehran and the United States, has already received several plaques and awards from the United Nations and the Iran’s Khwarizmi Scientific Foundation, performed this operation for the first time ever in 2007. He
