Objective To investigate the valuable echocardiographic parameters and to evaluate theright heart function of patients with pulmonary hypertension in ICU. Methods From March 2015 to February 2016,30 patients with pulmonary hypertension in the intensive care unit(ICU) of Dongzhimen hospital were enrolled in the experimental group,and another 33 patients without pulmonary hypertension in ICU were enrolled in the control group. All of the patients were given bedside echocardiography examination. Results Significant differences in the right atrial diameter and area ,the base diameter of the right ventricle ,the intermediate diameter portion ,the distal inner diameter of the proximal end of the right ventricular outflow tract ,the main pulmonary artery diameter ,the Tei index and the E/A were observed between the two groups. However ,no significant differences in the right ventricular free wall thickness,TAPSE,RVFAC,VREF and DT were foundbetween the two groups. Conclusion Tei index,the diameter of the right heart and the main pulmonary artery diameter are proposed to be the promising echocardiographic parameters to evaluate the right heart function of patients with pulmonary hypertension in ICU.

Objective To evaluate the effect of novel modified bipolar radiofrequency(RF) ablation for preoperative atrial fibrillation(AF) combined with off-pump coronary artery bypass grafting(OPCABG) for patients with AF and coronary artery disease(CAD).Methods From January 2007 to January 2014, 49 patients with AF, and CAD underwent the novel modified bipolar RF ablation combined with OPCABG in our department, 29 males and 20 females(11 paroxysmal, 19 persistent and 19 long-standing persistent).The patients were followed up with 24 hours Holter monitoring and echocardiography for (37.89 ± 18.1) months after the procedure.Results There were no perioperative death, serve low cardiac output syndrome or permanent pacemaker implantation.Mean AF ablation time was(33.2 ± 5.2) min, and the mean OPCABG time was(90.3 ± 16.6) min.Mean ICU stay time was(4.7 ± 2.5) days, and mean postoperative time was(14.5 ± 6.1) days.The maintenance of sinus rhythm was 93.9％ (46/49) at discharge, while the rate was 83.7 ％ (41/49) one year later.Follow-up echocardiography data at 6 months postoperatively showed that left atrial diameter was significantly reduced and left ventricular ejection fraction was significantly increased.Conclusion The novel modified bipolar RF ablation combined with OPCABG procedure was safe, feasible and effective.It may be useful in selecting the best ablation approaches for patients with AF and CAD.

Objective Objectives: To introduce the technique of performing minimally invasive concomitant Cox Maze Ⅳ ablation procedure entirely by bipolar clamp through right lateral minithoracotomy for patients with atrial fibrillation(AF) associated with mitral valve diseases.Methods Sixty nine patients with mitral valve disease and long-standing persistent AF received minimally invasive Cox Maze Ⅳ ablation procedure combined with mitral valve surgery from June 2012 to January 2015.The etiology of mitral valve disease was rheumatic(41 cases) and degenerative(28 cases).Age at operation ranged from 52 to 71 years.There were 43 males and 26 females.AF duration ranged from 1.5 years to 13 years.Diameter of the left atrium ranged from 42 to 60 mm.Diameter of the left ventricle ranged from 43 to 66 mm.Left ventricle ejection fraction (LVEF) ranged from 0.45 to 0.67.Concomitant Maze Ⅳ ablation procedure was performed through right lateral minithoracotomy entirely by bipolar radiofrequency clamp.Results All patients successfully underwent this minimally invasive concomitant Maze Ⅳ ablation procedure and mitral valve surgery.The mean cardiopulmonary bypass time was(130.3 ± 17.7) minutes.The mean aortic crossclamp time was(91.8 ± 12.7) minutes.No patient needed conversion to sternotomy during the surgery.There was no early death or pacemaker implantation in the perioperation.The average length of hospital stay was(9.8 ± 3.3) days.At discharge, 65 patients(65/69, 94.2％) maintained sinus rhythm.At a mean follow-up time of(21.0 ± 8.6) months, sinus rhythm was restored in 62 patients(62/69, 89.9％).Cumulative maintenance of normal sinus rhythm without AF recurrence at 2 years postoperatively was(85.1 ± 5.8)％.Conclusion The minimally invasive concomitant Maze Ⅳ ablation procedure performed entirely by bipolar clamp through right lateral minithoracotomy was a safe, feasible, and effective technique for patients with AF associated with mitral valve diseases.

Objective To study the diagnosis, treatment and prognosis of the rupture of breast implant. Methods Physical examination, X-ray fluoroscopy, high frequency and color the Doppler ultrasonography were helpful to make a clear diagnosis, in exploring and removing the fiber envelope by inframammary or periareolar incision, repairing the anatomy structure of the breasts and performing augmentation mammaplasty again. Results In 32 patients, the breast shape was basically symmetrical, most of the incisions were healed by first intention except 2 cases with complication of subcutaneous fluid collection. A satisfactory therapeautic result could be achieved by taking out the breast implant which was rupture, exploring and removing the fiber envelope, and extending the lacuna. Conclusion A satisfactory therapeautic result can be achieved by extending the lacuna.
