Abstract

BACKGROUND AND AIM OF THE STUDY:In 2009 our group described a new surgical technique for patients with severe mitral valve calcification undergoing mitral valve surgery. This technique creates a new mitral annulus with plication of the mitral leaflet and the atrial wall. Our objective is to report the long-term results of the experience at our institution. MATERIALS, METHODS, AND RESULTS:From 2007 to 2016, a total of 18 patients (mean age 70.5 ± 7.8 years) underwent mitral valve replacement at our institution with this technique. One patient died on the second postoperative day. Clinical and echocardiographic in-hospital and long-term follow-up (55.5 ± 40.4 months) were performed on all the remaining 17 patients. Functional improvement was achieved in all patients. Two patients died 6 and 8 years after surgery (cancer and hemorrhagic stroke). No prosthetic dysfunction, periprosthetic leak, or annular dehiscence were detected in the long-term echocardiographic examinations. CONCLUSIONS:The reconstruction of the mitral annulus by using our technique in patients with severe calcification of the mitral annulus has low long-term mortality, good functional results, and a lack of prosthetic complications.

摘要

研究背景和目的: 在2009中,我们的小组描述了一种新的外科技术,用于严重二尖瓣钙化的患者接受二尖瓣手术。这种技术创造了一个新的二尖瓣环,二尖瓣小叶和心房壁的折叠。我们的目标是报告我们机构经验的长期结果。 材料、方法和结果: 从2007至2016年,共有18例患者 (平均年龄70.5 ± 7.8岁) 在我们机构接受了二尖瓣置换术。一名患者在术后第二天死亡。对其余17例患者进行临床和超声心动图检查,并进行长期随访 (55.5 ± 40.4个月)。所有患者的功能均得到改善。两名患者在手术后6年和8年死亡 (癌症和出血性中风)。长期超声心动图检查未发现假体功能障碍、假体周围渗漏或环形裂开。 结论: 二尖瓣环重度钙化患者应用本技术重建二尖瓣环,远期死亡率低,功能恢复好,无假体并发症。

METHODS::We present the case of a 61-year-old woman with a large tumoral infiltration extending from the pelvis throughout the inferior vena cava inferior to the right atrium, protruding into the right ventricle and right ventricular outflow tract. She had been treated 10 years before for low-grade endometrial stromal sarcoma by hysterectomy and adnexectomy followed by hormone- and radio-therapy. Due to cancer recurrence, she underwent peritonectomy, appendectomy, and resection of terminal ileum.

METHODS:AIMS:Significant platelet activation after long stented coronary segments has been associated with periprocedural microvascular impairment and myonecrosis. In long lesions treated either with an everolimus-eluting bioresorbable vascular scaffold (BVS) or an everolimus-eluting stent (EES), we aimed to investigate (a) procedure-related microvascular impairment, and (b) the relationship of platelet activation with microvascular function and related myonecrosis. METHODS AND RESULTS:Patients (n=66) undergoing elective percutaneous coronary intervention (PCI) in long lesions were randomised 1:1 to either BVS or EES. The primary endpoint was the difference between groups in changes of pressure-derived corrected index of microvascular resistance (cIMR) after PCI. Periprocedural myonecrosis was assessed by high-sensitivity cardiac troponin T (hs-cTnT), platelet reactivity by high-sensitivity adenosine diphosphate (hs-ADP)-induced platelet reactivity with the Multiplate Analyzer. Post-dilatation was more frequent in the BVS group, with consequent longer procedure time. A significant difference was observed between the two groups in the primary endpoint of ΔcIMR (p=0.04). hs-ADP was not different between the groups at different time points. hs-cTnT significantly increased after PCI, without difference between the groups. CONCLUSIONS:In long lesions, BVS implantation is associated with significant acute reduction in IMR as compared with EES, with no significant interaction with platelet reactivity or periprocedural myonecrosis.

METHODS:BACKGROUND:Aortopulmonary window is an uncommon congenital heart disease, with untreated cases not surviving beyond childhood. However, very rarely it can present in adult patients with features of pulmonary hypertension. Clinically these patients cannot be differentiated from other more common conditions with left to right shunt. Transthoracic echocardiography if performed meticulously, can depict the defect in aortopulmonary septum. RESULTS:We report a case of large unrepaired aortopulmonary window in a 23 years old patient, diagnosed on transthoracic echocardiography.
