ABSTRACT

Objective:To evaluate the early effects of combined transaortic and transapical approach to septal myectomy in patients with complex hypertrophic obstructive cardiomyopathy(HOCM).Methods:We consecutively enrolled 20 complex HOCM patients who received transaortic and transapical myectomy in fuwai hospital from January 2019 to October 2019. Echocardiography was performed to compare left atrial size, left ventricular end diastolic diameter, peak left ventricular outflow gradient, ventricular septal thickness, mitral systolic anterior motion and mitral regurgitation grade before and after operation. Furthermore, pre-operative and post-operative electrocardiogram were also analyzed to determine the incidence of bundle branch block. Functional status was evaluated by New York Heart Association functional class.Results:Of the 20 complex hypertrophic cardiomyopathy patients, 7(35%) HOCM patients with long-segment septal hypertrophy more than 7cm, 4(20%) patients had both mid-ventricular obstruction and left ventricular outflow obstruction. Apical hypertrophic cardiomyopathy with LOVT obstruction was observed in 5 patients(25%) and aneurysm was found in 4(20%) HOCM patients. Postoperative thickness of ventricular septum was significantly decreased compared with that of preoperation[(21.1±3.6)mm vs.(13.4±3.1)mm]. Peak LOVT gradient or mid-ventricular gradient also significantly reduced after operation[(77.0±21.0) mmHg vs.(9.2±3.4) mmHg] or [(71.0±23.0) mmHg vs. 0 mmHg, 1 mmHg=0.133 kPa]; After surgery, mitral systolic anterior motion disappeared, mitral regurgitation degree reduced from (1.9±1.5) to (0.2±0.4); NYHA class improved from(2.1±0.2) to(1.3±0.5). New incidence of left bundle branch block occurred in 9 patients, and 1 patient developed complete bundle branch block and implanted permanent pacemaker. The 30-day survival was 100%.Conclusion:Combined transaortic and transapical septal myectomy is an effective and reasonably safe procedure for patients with complex hypertrophic obstructive cardiomyopathy.

ABSTRACT

Objective@#To investigate the clinical features and surgical treatment effect of patients with cardiac cavernous hemangioma.@*Methods@#Clinical data of 9 patients (5 male, aged from 4 to 53 years old) with cardiac cavernous hemangioma, who underwent surgical treatment from November 2002 to March 2015 and the diagnosis of cardiac cavernous hemangioma was confirmed by postoperative histological examination, were retrospectively analyzed. Effects of surgical treatment were analyzed.@*Results@#Four patients were asymptomatic (heart murmur presented in 3 patients during physical examination). Three patients presented with palpitation, chest distress, and short of breath. One patient presented with epigastric discomfort and another patient presented with intermittent fever for more than 10 months. ST and T wave changes of electrocardiogram were found in 2 patients, cardiac mass was detected in the right heart chamber in 5 patients by echocardiography, and no cardiac mass was detected the rest 4 patients. Cardiac masses were resected en bloc, then the adjacent tissues were repaired in 7 patients, and mass was partially resected due to the involvement with adjacent heart structure. No cardiac mass was found during operation in 1 case, impaired mitral valve structure was excised and postoperative pathologically confirmed as cardiac valve cavernous angioma on the excised mitral valve structure. No signs of recurrence or enlargement of cardiac cavernous hemangioma were found during the 11(10, 11)years follow up.@*Conclusions@#There is no specific clinical feature for patients with cardiac cavernous hemangioma. It is difficult to detect the cardiac valve cavernous angioma by echocardiography before surgery. Individualized surgical treatment is associated with good clinical outcome in this patient cohort. However, the clinical features and surgical treatment effect of patients with cardiac cavernous hemangioma still need to investigate in large sample trial.

ABSTRACT

Objective To detect the expression of hypoxia-inducible factor 1α (HIF-1α) and bcl-2 ovarian serous carcinoma and their clinical significances. Methods Paraffin specimens including 61 cases of ovarian serous carcinoma and 50 normal ovarian tissues were selected. The expressions of HIF-1α and bcl-2 proteins were detected by immunohistochemical EnVision method and their relationship between them was analyzed. Results The positive rate of HIF-1α and bcl-2 proteins expression in 61 ovarian serous carcinoma was 68.9%and 54.1%, respectively. There was a significant difference between the two groups (χ2=55.381, P0.05). HIF-1αpositive expression was correlated with tumor grades, the state of lymph node metastasis and FIGO stages (χ2=4.931, 25.008, 5.610, P0.05). The expression of bcl-2 was positively correlated with HIF-1α in ovarian serous carcinoma (r= 0.304, P= 0.017). Conclusions The expressions of HIF-1α and bcl-2 play a synergic role in the progression of ovarian serous carcinoma. The combined detection of HIF-1αand bcl-2 is effective for patients'prognosis judgment.

ABSTRACT

Objective: To summarize the major post-operative complication of modiifed extended Morrow procedure in patients with hypertrophic obstructive cardiomyopathy (HOCM) and to explore the major factors affecting its prognosis. Methods: We retrospectively analyzed 139 consecutive HOCM patients who received the procedure by same surgeon in our hospital from 2012-06 to 2014-07. There were 87 male and 52 female patients with the age of (10-67) years, body weightof (26-105) kg and pre-operative left ventricular outlfow tract peak gradient (LVOTPG) of (84.48 ± 44.75) mmHg. Concomitant operations were performed with known cardiac disease as necessary. Pre- and post-operative echocardiography, ECG and chest X-ray were examined to assess the adequacy of resection and mitral valve structure and function. Results: There was no peri-operative death. 73/139 (53%) patients received simple modiifed expanded Morrow procedure, the other 66 (47%) patients received concomitant surgery including 21 patients with coronary artery bypass grafting, 15 mitral valve plasty, 7 mitral valve replacement, 10 tricuspid valve plasty, 2 aortic valve replacement, 3 modiifed Maze procedure, 2 unblock of right ventricular outlfow tract, 2 sub aortic membrane resection, 1 ventricular aneurysm resection. The mechanical ventilation time was (24.05±36.74) hours, post-operative ICU and in-hospital stays were (2.85±3.18) days and (10.11±4.57) days; the complications included arrhythmia in 108 cases, pleural effusion in 25 cases, secondary intubation in 1 case, tracheotomy in 1 case, hemoifltration in 1 case, intra-aortic balloon pump in 1 case, back into ICU in 3 cases; no pneumothorax, secondary thoracotomy/operation. The post-operative left atrial diameter, LVOTPG, inter-ventricular septal thickness and LVEF were all decreased; mitral valve closed well or with mild regurgitation, systolic anterior motion (SAM) basically disappeared. The major factors for delayed ICU stay included age≥55 years, female, CPB time≥120 min, AOC time≥90 min, the patients combining with arrhythmia and right ventricular dysfunction. Late follow-up presented that the patients were almost without the symptoms, NYHA classiifcation at (I-II), no late death, complication or re-operation. Conclusion: Modified expand Morrow procedure has good surgical and short/late post-operative effects, concomitant operation does not increase the complication and mortality; correction of arrhythmia and improving right ventricular function at peri-operative period are important for treating the relevant patients.
