Abstract
Objective: To examine minimally invasive tricuspid valve operations applied in tricuspid valve insufficiency patients with previous left-sided valve surgery. Methods: Between September 2017 and June 2019, thirty-six consecutive patients received minimally invasive totally thoracoscopic tricuspid surgery through right thoracotomy at Department of Cardiovascular Surgery, Fisrt Medical Center, People's Liberation Army General Hospital. There were 13 males and 23 females, aging (56±11) years (range: 43 to 79 years). All the patients had isolated significant tricuspid regurgitation after previous left-sided cardiac surgeries. A right anterolateral thoracotomy incision about 4 cm was made from the fourth intercostal space as main operating port. The arterial cannula was placed in femoral artery. The venous cannula was placed in femoral vein using Seldingger technique. Tricuspid valve operation was performed on beating heart by assist of vena vacuum. Results: Tricuspid valve repair was performed in 7 patients. Tricuspid valve replacement with bioprosthesis was performed in 29 patients. The operation time was (2.9±0.3) hours (range:2.5 to 3.6 hours). There was no conversion to sternotomy during operation. There was no severe complications during operation period. There were no complications related to this cannulation technique. The time of cardiopulmonary bypass establishment was (22±5) minutes (range: 12 to 24 minutes) and pump time was (82±16) minutes (range: 62 to 93 minutes). The length of hospital stay was (9±3) days after operation (range: 5 to 13 days). There was no early death in hospital. All patients were followed up for 3 to 22 months. No patient died. Conclusions: One single port-based minimally invasive approach seems to be safe, feasible, and reproducible in case of redo tricuspid valve operations. Only cannulation of inferior vena cava significantly simplified the complexity of isolated redo tricuspid surgery.
