目的:回顾两种二尖瓣成形术治疗合并主动脉根部瘤的二尖瓣反流,探讨此手术的临床效果。方法:2010年7月至2015年5月,北京安贞医院收治的33例合并主动脉根部瘤的二尖瓣反流的患者进行回顾性分析,男性28例,女性5例,平均年龄(53.2±15.5)岁。其中25例患者置入二尖瓣成形环(成形环植入组),所置入的二尖瓣人工瓣环平均直径为(29.5±1.5)mm,8例患者行交界环缩术(交界环缩组)。术前超声心动图显示:所有患者二尖瓣病变均为中度或重度关闭不全,成形环植入组反流面积为(8.5±4.1)cm2,交界环缩组反流面积为(5.7±1.3)cm2。成形环植入组患者平均体外循环时间(164.2±29.3)min,平均主动脉阻断时间(118.2±23.4)min,交界环缩组患者平均体外循环时间(111.9±28.4)min,平均主动脉阻断时间(77.8±22.2)min。结果:术后无死亡,无恶性心律失常及其他严重并发症。成形环植入组术后平均ICU停留时间为(23.0±12.5)h,交界环缩组术后平均ICU停留时间为(23.0±8.8)h。复查超声心动图显示:成形环植入组少量反流8例,无或微量反流17例;交界环缩组少量反流4例,无或微量反流4例。结论:二尖瓣反流合并主动脉根部瘤时可以经房间隔切口或房间沟切口行成形环植入术和经主动脉切口行交界环缩术。上述两种二尖瓣成形术治疗主动脉根部瘤合并二尖瓣反流的效果确切,对于二尖瓣反流程度较轻的患者可以采用经主动脉切口行交界环缩术,以减少体外循环和阻断的时间。  相似文献

Opinion statement  
–  It is well recognized that the floppy mitral valve (FMV) complex is the central issue in the FMV, mitral valve prolapse (MVP), and mitral valvular regurgitation (MVR) story. MVP associated with the FMV results from the systolic movement of portions or segments of the FMV complex into the left atrium (LA). Prolapse of the FMV results in unique forms of mitral valvular dysfunction and MVR. When the FMV is recognized as the basic point of reference, diagnostic and nosologic characterizations are simplified. Each of the consequences of FMV dysfunction—MVP, MVR, and FMV surface phenomena—are dynamic entities and contribute to the symptoms and clinical course in this patient population.
–  Although MVP may occur in the absence of a FMV in individuals with small left ventricular (LV) volume, hyperdynamic, or hypercontractile LV, we do not consider this phenomenon as part of FMV/MVP/MVR.
–  The natural history of the FMV/MVP/MVR is long, and understanding the life history requires long-term follow-up with serial evaluations.
–  Identification of those individuals with FMV/MVP whose symptoms are related to, or associated with, autonomic nervous system dysfunction (ie, the FMV/MVP syndrome) is important, as this distinction has diagnostic and therapeutic implications.
–  In general, patients with FMV/MVP should receive antibiotic prophylaxis for infective endocarditis.
–  Data suggest that therapy with angiotensin-converting enzyme inhibitors for FMV/MVP and significant MVR may slow the natural regression of the disease.
–  Surgical therapy should be considered in patients with significant MVR and symptoms related to MVR.
–  Explanation for the nature of these symptoms, reassurance, avoidance of volume depletion, catecholamines or other cycle-AMP stimulants and a regular exercise program constitute the basic principles of management for patients with FMV/MVP syndrome.

One hundred and twenty-six patients of rheumatic mitral stenosis (MS), aged 10-30 (mean 19.5 +/- 5.9) years underwent balloon mitral valvuloplasty (BMV). All valvuloplasties were done by the anterograde transvenous, transatrial route. The procedure was successful in 120 (95%) cases. Single balloon was used in 10 patients early in the series and double balloon was used in the other 110 patients. BMV resulted in a significant increase in the mitral valve area (MVA) from 0.96 +/- 0.35 to 2.3 +/- 0.8 cm2 (p less than 0.0001) and a significant fall in the transmitral pressure gradient (TMG) from 28.2 +/- 3.2 to 7.4 +/- 4.8 mmHg (p less than 0.001). The MVA achieved by BMV was found to have a significant positive correlation with the balloon diameter to body surface area ratio (BD/BSA) (r = 0.69, p less than 0.001). New mitral regurgitation (MR) developed in 15 patients--trivial in 11, 2+ in 2 and 3+ in 2. One patient required emergency mitral valve replacement. Procedure induced MR did not have a significant relation to the balloon size, degree of mitral sub-valvular pathology or the severity of mitral stenosis. Iatrogenic atrial septal defect was detected by oximetry in none, by angiography in one patient, and by Doppler color flow imaging in 5 patients. Cardiac tamponade was the most frequent serious complication, occurring in 6 patients, 4 of whom died following emergency surgery. Sixty-five patients have been followed up for at least 6 months (range 6-30, mean 16.3 +/- 6.3 months) following BMV.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

We report 7 symptomatic patients with stenotic double-orifice mitral valve of incomplete bridge type. In each patient, the fibrous bridge tissue between the valve leaflets was successfully split using an Inoue balloon valvuloplasty technique with stepwise dilations applied only to the posteromedial orifice.  相似文献

Percutaneous mitral valve repair for mitral regurgitation   总被引:5,自引:0,他引:5  
Mitral regurgitation (MR) associated with, ischemic, and degenerative (prolapse) disease, contributes to left ventricular (LV) dysfunction due to remodeling, and LV dilation, resulting in worsening of MR. Mitral valve (MV) surgical repair has provided improvement in survival, LV function and symptoms, especially when performed early. Surgical repair is complex, due to diverse etiologies and has significant complications. The Society for Thoracic Surgery database shows that operative mortality for a 1st repair is 2% and for re-do repair is 4 times that. Cardiopulmonary bypass and cardiac arrest are required. The attendant morbidity prolongs hospitalization and recovery. Alfieri simplified mitral repair using an edge-to-edge technique which subsequently has been shown to be effective for multiple etiologies of MR. The MV leaflers are typically brought together by a central suture producing a double orifice MV without stenosis. Umana reported that MR decreased from grade 3.6 +/- 0.5 to 0.8 +/- 0.4 (P < 0.0001) and LV ejection fraction increased from 33 +/- 13% to 45 +/- 11% (P = 0.0156). In 121 patients, Maisano reported freedom from re-operation of 95 +/- 4.8% with up to 6 year follow-up. Oz developed a MV "grasper" that is directly placed via a left ventriculotomy and coapts both leaflets which are then fastened by a graduated spiral screw. An in-vitro model using explanted human valves showed significant reduction in MR and in canine studies, animals followed by serial echo had persistent MV coaptation. At 12 weeks the device was endothelialized. These promising results have paved the way for a percutaneous or minimally invasive-off pump mitral repair. Evalve has developed catheter-based technology, which, by apposing the edges of a regurgitant MV, results in edge-to-edge repair. Release of the device is done after echo and fluoroscopic evaluation under normal loading conditions. If the desired effect is not produced the device can be repositioned or retrieved. Animal studies show excellent healing, with incorporation of the device into the leaflets at 6-10 weeks with persistent coaptation. Another percutaneous approach has been to utilize the proximity of the coronary sinus (CS) to the mitral annulus (MA). Placement of a self-compressing device in the CS along the region of the posterior MA has, in canine models, reduced MR and addresses the issues of MA dilation and its contribution to MR. Ongoing studies are underway for both techniques.  相似文献

分级次二尖瓣球囊扩张预防二尖瓣反流的初步研究   总被引:9,自引:0,他引:9  
目的为探讨经皮穿刺球囊导管二尖瓣扩张术(PBMV)引起二尖瓣反流(MR)的原因及其预防方法。方法我们采用分级次扩张法和改良Inone法对人体病变二尖瓣和硅胶二尖瓣模型进行体外球囊导管扩张实验,并对132例风湿性心脏病重度二尖瓣狭窄患者,其中分别以分级次扩张法96例,Inone法36例进行PBMV的前瞻性对比研究。结果(1)PBMV引起二尖瓣反流的原因除与瓣膜钙化程度重、瓣下结构紊乱有关以外,瓣口面积小、交界粘连处夹角小是一个重要原因。(2)分级次扩张可使交界粘合处夹角呈渐进性扩大,扩张时不易引起瓣膜撕裂和二尖瓣反流。两组比较Inone法扩张组二尖瓣反流发生率为16.7%,分级次扩张组无二尖瓣反流病例,并且术中其他并发症及术后再狭窄发生率后者也明显低于前者。结论球囊导管分级次扩张可有效地预防二尖瓣反流,是治疗二尖瓣狭窄较理想的方法。  相似文献
