23 patients with mitral stenosid with or without mild mitral open, ages of 23-50 (male: 10) received an operation. As the results of direct measurement of pulmonary arterial pressure and left atrial pressure in an operation have shown that the pulmonary arterial pressure was direct correlated before and after operation(r= 0.572 before operation; r=0.65 after operation).These parameters were reduced significantly and rapidly after operation when comparing with these before operation.

A study was carried out on the 23 patients (male:10, female: 13) with the mitral stenosid with merely close or combination with the mild mitral open (grade III), ages of 23-50 indicated an operation for seperation of close valve in the Army Central hospital 108 during 1/1998 to 10/1999 in which there were 5 patients with the mitral stenosid, 18 patients with the mitral stenosid in combination with the mitral open grade I, II, 14 patients with the atrial rhythm, 9 patients with atrial fibrillation. The atrial pressure reduced from 15-67 mmHg to 15-45 mmHg. There was a direct proportional between the left atrial and right ventricular pressures

OBJECTIVETo investigate the value of transesophageal echocardiography to guide the implantation of 2 pieces of MitraClip during transcatheter mitral valve repair operation.

METHODSFrom October 2013 to June 2014, 6 transcatheter mitral valve repair operations were performed in our hospital for symptomatic patients with severe functional mitral regurgitation (MR), transesophageal echocardiography was applied to guide the implantation of 2 pieces of MitraClip. Clinical data are retrospectively analyzed to evaluate implantation timing and approach of the 2nd piece of MitraClip, as well as the immediate effect of the interventional therapy.

RESULTSAfter implantation of 1st piece of MitraClip, transesophageal echocardiography evidenced MR ≥ grade 2 with central regurgitation and immediate mitral average transvalvular pressure gradient < 3 mmHg (1 mmHg = 0.133 kPa) in these 6 patients and 2nd piece of MitraClip was implanted in these patients. After implantation of 2nd piece of MitraClip, it is observed via transesophageal echocardiography that mitral regurgitations were reduced by ≥ 2 grades for all 6 patients. For 3 patients, MR was reduced to grade 1. For the other 3 patients, MR is reduced to grade 2. Among the 3 patients whose MR was reduced to grade 2, 2 operations were stopped because immediate mitral average transvalvular pressure gradient equaled to 3 mmHg, and the rest 1 operation was stopped because MR was too diverse and not able to select proper position to implant the next MitraClip. All 6 operations are completed successfully.There were no myocardial infarction, death or complications requiring mitral valve surgery after the MitraClip procedure. There were also no MitraClip detachment, thrombus embolism, mitral valve apparatus injuries, mitral stenosis, pericardial tamponade post procedure.

CONCLUSIONSTransesophageal echocardiography plays an important role to guide the implantation of 2 pieces of MitraClip in transcatheter mitral valve repair operation. Mitral average transvalvular pressure gradient and initial position of regurgitation after implantation of the previous MitraClip are critical determinants for decision making if the next piece of MitraClip can be implanted or not.

Transcatheter aortic valve implantation (TAVI) has shown favorable outcomes in patients with severe symptomatic aortic valve stenosis who are at high surgical risk or are unsuitable candidates for open heart surgery. However, concerns exist over treating patients who have previously undergone mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and the TAVI device. In this case report, we present a patient with symptomatic severe aortic stenosis and previous mechanical mitral valve replacement who was successfully treated with TAVI using a CoreValve.

A 45-year-old woman was diagnosed as having chylothorax after a mitral valve replacement for mitral stenosis. direct injury of lymphatics in thymus a ramification of thoracic duct was presumed to be responsibe for this complication. Four weeks of conservative treatment failed and surgical treatment was performed, We report a case of surgical treatment for chlyothorax after and open heart surgery.

We experienced a case of pedunculated left atrial primary fibrosarcoma, which obstructed the mitral orifice and produced symptoms and manifestations of mitral stenosis clinically. There was no evidence of metastasis to adjacent tissue or distant organs. It was treated by open heart surgery.

We have experienced a case of deflation failure of Inoue balloon in the left atrium during mitral balloon valvuloplasty in a 44 year old male patient with tight mitral stenosis, who died just after emergency open heart surgery for removal of undeflated Inoue balloon and mitral valve replacement because of associated acute hemorrhagic myocardial infarction.
