The Conquest Pro 12 Sharpened Tip (CP12ST) is a novel guidewire used in intervention for coronary chronic total occlusion, with strong penetration force for hard plaques. Antegrade dissection and reentry techniques using the CP12ST have been reported, and their success and safety have been established. This report describes successful retrograde dissection and reentry using the CP12ST under intravascular ultrasound guidance in a situation in which reverse controlled antegrade and retrograde tracking was difficult to perform.

Conquest Pro 12 磨尖导丝(CP12ST)是一种用于冠状动脉慢性全闭塞介入治疗的新型导丝,对硬斑块具有很强的穿透力。使用 CP12ST 的前行剥离和再入技术已有报道,其成功性和安全性已得到证实。本报告描述了在血管内超声引导下使用 CP12ST 成功进行逆行剥离和再通的情况,在这种情况下很难进行反向控制的逆行和顺行追踪。

A 78-year-old man with angina and ischemic cardiomyopathy presented for LAD CTO PCI. After several failed techniques, the LAD was recanalized with subintimal tracking and reentry (STAR) with subsequent balloon angioplasty of the false lumen. No stent was deployed and the patient did not follow-up for 10-months for definitive PCI. On follow-up, IVUS findings suggested the presence of a new external elastic lamina in the false lumen (side-by-side to the true lumen), indicating favorable healing. PCI was performed with an excellent angiographic result. Our case highlights a mechanism of vascular healing following dissection and re-entry-based recanalization of an LAD CTO.

一名 78 岁的男性患有心绞痛和缺血性心肌病,前来接受 LAD CTO PCI 治疗。经过数次失败后,使用内膜下追踪和再入(STAR)术对 LAD 进行了再通路,随后对假管腔进行了球囊成形术。患者没有植入支架,10 个月后没有进行明确的 PCI 随访。随访时,IVUS检查结果显示假腔(与真腔并排)出现了新的外弹力层,表明愈合良好。PCI术后血管造影效果极佳。我们的病例强调了LAD CTO剥离后血管愈合的机制,以及基于再入口的再封堵。

We describe a case of sub-adventitial hematoma of the ascending aorta at the level of the crown of supra-annular TAVR presenting 4 months post procedure. Acute aortic syndromes following TAVR portend grave prognosis and warrant emergent reconstructive surgery. However, the less known, chronic aortic complications may have an indolent presentation. Our patient underwent aortic reconstructive surgery with TAVR explant and bio-prosthetic AVR implantation and had a favorable outcome.

我们描述了一例术后 4 个月出现在环上 TAVR 冠状动脉水平的升主动脉室内下血肿病例。TAVR 术后急性主动脉综合征预示着严重的预后,需要紧急进行重建手术。然而,较少为人所知的慢性主动脉并发症的表现可能并不明显。我们的患者接受了主动脉重建手术,进行了 TAVR 移植和生物假体 AVR 植入,结果良好。

Rotational atherectomy (RA) is a necessary procedure for severely calcified lesions. We describe for the first time a case of RA through the left upper limb into LIMA to LAD in a last remaining vessel.

旋转动脉粥样硬化切除术(RA)是严重钙化病变的必要手术。我们首次描述了一例通过左上肢进入 LIMA 至 LAD 的最后一根残存血管的 RA 病例。

A 38-year-old male presented with recurrent myocardial infarction (MI). Subsequent investigations led to the diagnosis of essential thrombocytosis (ET) with a positive JAK2-V617F mutation. ET should be ruled out in young patients presenting with MI, even in the presence of typical cardiac risk factors.

Rheumatic mitral stenosis has a large patient base and a certain incidence in developing countries. Percutaneous balloon valvuloplasty is one of the main treatments for such patients, but this method is limited by the degree of mitral regurgitation. Here, we describe a 74-year-old patient with rheumatic mitral stenosis without calcification observed by transthoracic echocardiography and computed cardiac tomography, and no calcification was found in the mitral annulus. The score of Society of Thoracic Surgeons was 14.2%, with Wilkins score of 12. Under the guidance of 3-dimensional printing technology, transcatheter mitral valve replacement was successfully performed. Before discharge, the stability and function of the bioprosthesis were confirmed.

风湿性二尖瓣狭窄患者人数众多,在发展中国家也有一定的发病率。经皮球囊瓣膜成形术是此类患者的主要治疗方法之一,但这种方法受到二尖瓣反流程度的限制。在此,我们描述了一名 74 岁的风湿性二尖瓣狭窄患者,经胸超声心动图和计算机心脏断层扫描观察,二尖瓣环内未发现钙化。胸外科医师协会评分为 14.2%,Wilkins 评分为 12 分。在三维打印技术的指导下,成功实施了经导管二尖瓣置换术。出院前,确认了生物瓣膜的稳定性和功能。

We present a case of symptomatic left anterior descending (LAD) artery to right ventricle fistula formation, following orthotopic heart transplant. Closure of the shunt with a covered stent in the LAD was a satisfactory initial management strategy, however long-term is limited by recurrent severe in-stent restenosis. The etiology, as well as the best long-term management strategy for this unusual complication is not well defined.

我们介绍了一例心脏移植后出现症状性左前降支(LAD)动脉至右心室瘘形成的病例。在左心室前降支动脉上使用有盖支架关闭分流是一种令人满意的初步治疗策略,但由于支架内反复出现严重的再狭窄,长期治疗受到限制。这种不寻常并发症的病因和最佳长期治疗策略尚未明确。
