[Early cardiovascular complications post lung transplantation].

OBJECTIVE

To observe the early cardiovascular complications of patients underwent lung transplantation.

METHODS

The clinical records of 73 patients who underwent lung transplantation in Wuxi People's Hospital from September 2002 to September of 2010 were retrospectively analyzed. All patients were transferred to intensive care unit (ICU) after lung transplantation, received invasive monitoring (PICCO), mechanical ventilation, immunosuppressive therapy and measures to prevent ischemic reperfusion injury. The early cardiovascular complications after lung transplantation up to discharge from hospital were observed.

RESULTS

The postoperative mortality was 20.5% (15/73) within 30 days after surgery. Five patients died of cardiovascular reasons including 2 cases of pulmonary embolism and 3 cases of ventricular fibrillation. Cardiovascular complications during the early post-operation period included: paroxysmal atrial fibrillation (19 cases, 26.0%) and persist atrial fibrillation (1 case, 1.4%); atrial fibrillation and atrial flutter in 3 cases and persistent atrial flutter in 1 patient; ventricular fibrillation (3 cases, 4.1%); paroxysmal supraventricular tachycardia (3 cases, 4.1%); ventricular tachycardia (2 cases, 2.7%); bundle branch block (8 cases, 11.0%); intraventricular block(4 cases, 5.5%); left ventricular heart failure(4 cases, 5.5%), right heart failure(6 cases, 8.2%); pulmonary embolism (2 cases, 2.7%), deep venous thrombosis (1 case, 1.4%).

CONCLUSIONS

Atrial fibrillation is the most common cardiovascular complication post lung transplantation. Pulmonary embolism and ventricular fibrillation are not common but related with high mortality rate post lung transplantation.
