Project description:BackgroundCoronary artery aneurysms (CAAs) of the left main represent a small subset of coronary artery disease and are associated with cardiovascular death. Because of its rare entity, large data are lacking and therefore treatment guidelines are missing.Case summaryWe describe a case of a 56-year-old female with a past medical history of spontaneous dissection of the distal descending left artery (LAD) 6 years before. She presented to our hospital with a non-ST elevation myocardial infarction and a coronary angiogram showed a giant saccular aneurysm of the shaft of the left main coronary artery (LMCA). Given the risk of rupture and distal embolization, the heart team decided to go for a percutaneous approach. Based on a pre-interventional 3D reconstructed CT scan and guided by intravascular ultrasound, the aneurysm was successfully excluded with a 5 mm papyrus-covered stent. At 3-month and 1-year follow-up, the patient is still asymptomatic and repeat angiographies showed full exclusion of the aneurysm and the absence of restenosis in the covered stent.DiscussionWe describe the successful percutaneous IVUS-guided treatment of a giant LMCA shaft coronary aneurysm with a papyrus-covered stent with an excellent 1-year angiographic follow-up showing no residual filling of the aneurysm and no stent restenosis.

Project description:BackgroundLeft main (LM) perforations necessitating a covered stent risk sacrificing the side branch. The lost side branch can be promptly recovered by fenestration of the covered stent, using a stiff wire. However, it is unclear whether subsequent balloon angioplasty of the recovered side branch ostium is sufficient to preserve side branch patency. We report the longer-term patency of the circumflex (LCx) ostium after LM covered stenting.Case summaryA 78-year-old lady, with stable angina, presented for elective angiography. Percutaneous coronary intervention of the left anterior descending (LAD) artery to LM was complicated by a distal LM perforation. A covered stent across the LM sealed the perforation but resulted in acute occlusion of the LCx. The LCx was rescued by fenestration of the covered stent with a stiff wire, followed by balloon angioplasty to the LCx ostium. At follow-up, the angina had resolved. However, follow-up angiography demonstrated a new severe stenosis at the LCx ostium, with remnants of the polyurethane membrane seen protruding into the LCx ostium on optical coherence tomography. Therefore, the LCx ostium was stented, using the reverse Culotte technique.ConclusionThis case demonstrates that stenting the LCx ostium should be considered after covered stent implantation from LM to LAD, because balloon angioplasty of the LCx ostium may not provide a durable result in this scenario.

Project description:Background:The percutaneous treatment of heavily calcified coronary lesions is challenging and presents high rate of complications. Unexpandable stent is one of the most serious complication. Both of these conditions may benefit from the intracoronary lithotripsy (ICL-Shockwave®), a new coronary percutaneous technique. Case summary:This case report describes a man treated with percutaneous coronary intervention (PCI) for a left main (LM) severe calcified lesion. The PCI was complicated by a huge dissection of LM in a not completely expandable lesion. A bail-out stent implantation was performed with residual unexpansion. The ICL permitted to expand acutely the stent and obtain an optimal final result. Discussion:Familiarity with dedicated techniques and devices to treat calcified coronary lesions is fundamental to perform high-risk complex PCI. This case emphasizes the potential usefulness of the new ICL technique to treat calcified lesions or related complications like unexpandable stent.

Project description:A 79-year-old woman developed a hemothorax 2 days after implantation of a permanent pacemaker. Computed tomography angiography revealed active extravasation from the left internal mammary artery. A covered stent was deployed to manage the arterial perforation. This case report explores different venous access techniques to minimize the risk of arterial injuries and describes the use of a covered stent in managing a non-grafted left internal mammary artery injury from a pacemaker implantation procedure.

Project description:Advances in stent design and technology have made stent loss during percutaneous coronary interventions rare. When an undeployed stent dislodges in the left main (LM) artery during percutaneous coronary angioplasty, the risk of life-threatening procedural complications is high. We report a 50-year-old male patient, a smoker, with a history of diabetes mellitus and hypertension with typical chest pain on minimal exertion. Electrocardiogram and echo revealed ischemic changes and regional wall motion abnormality. Culotte technique was used. A new 3 mm × 48 mm stent was inserted in the LM-left circumflex (LM-LCX) followed by stenting of the LM-left anterior descending (LM-LAD) ostia with a 3.5 mm × 18 mm stent. The two balloons were rewired and kissed. Stent slippage and dislodging in the LM artery can be corrected using the culotte technique to crush the undeployed stent behind the LM-LCX and LM-LAD stents.

Project description:BackgroundPericardial effusion is a common complication of percutaneous left atrial appendage (LAA) closure. Acute management is the cornerstone of pericardial effusion treatment and interrupting the intervention is often required.Case summaryA 65-year-old man presented an acute 10 mm pericardial effusion following pigtail contrast appendage injection. A rapid Watchman Flex 24 mm (Boston Scientific) deployment permitted bleeding interruption. A needle pericardiocentesis was achieved in order to prevent any haemodynamical instability.DiscussionThis case report describes an atypical cause of pericardial effusion and a technique for bleeding control with LAA closure device deployment.

Project description:RationaleEmbolization of a deployed stent is a rare complication and its mechanism remains unclear in most cases.Patient concernsA 52-year-old man underwent coronary angiography for effort angina, revealing an 80% stenosis of the proximal left anterior descending (LAD) involving the distal left main (LM). After luminal sizing with intravascular ultrasound two drug-eluting stents were deployed (5.0?×?12?mm and 3.5?×?15?mm) to cover the LM-LAD lesion. After postdilatation, the proximal stent had disappeared from the LM.DiagnosesThe missing stent was found in the right deep femoral artery.InterventionsA new 5.0?×?15?mm stent was deployed onto the LM-LAD ostium, in overlapping with the previously implanted. Then, the stent migrated to the deep femoral artery was successfully retieved through the contralateral femoral artery.OutcomesThe patient was discharged 2 days later, after an uneventful hospital stay.LessonsStent deformation after postdilation is a possible causes of stent migration.

Project description:Right coronary artery perforation extending to the sinus of Valsalva is a rare and potentially fatal complication of percutaneous coronary intervention. There are no definite guidelines on the management strategies for such complications. Treatment modality depends on the patient's haemodynamic stability and the extent of aortic involvement. Polytetrafluoroethylene-covered stents have emerged as a revolutionary strategy, enabling efficient endovascular repair of the entry port of such dissections, particularly the coronary ostia, and obviating the need for high-risk emergent surgical intervention.A 60 year old Bangladeshi gentleman underwent a coronary angiogram following a prior inferior ST elevation myocardial infarction (MI), 1 month previously. Coronary angiography done via right radial approach using 5 FR TIG catheter showed diffuse mid RCA disease with maximum 90% stenosis. Angioplasty of the RCA was planned. The RCA was cannulated with a 6-French JR 3.5 guiding catheter (USA). The lesion was crossed by a 0.014 inch guide wire and stented with a 2.75 × 38 mm novolimus-eluting DESyne stent, after predilatation. Immediately after stenting, a Type II perforation was observed in the ostial RCA, which progressed into the right coronary sinus of Valsalva. As the patient was haemodynamically stable with no ischaemia on ECG, we attempted to seal the ostial RCA with bare metal stents. Two successive bare metal stents failed to seal the aorto-coronary dissection. Ultimately, a 3.0 × 19 mm polytetrafluoroethylene-covered stent was deployed to seal the entry port in the ostial RCA, yielding a satisfactory angiographic result with only minimal contrast staining limited to the right sinus of Valsalva. The patient was closely monitored and discharged on dual antiplatelet therapy comprising of aspirin and prasugrel. He remained asymptomatic and with follow up echocardiograms showing no pericardial effusion nor extension of the dissection.The polytetrafluoroethylene-covered stent provides a safe and effective means of sealing iatrogenic aorto-coronary dissections complicated by Ellis type II or II perforations, thus avoiding emergency surgery. However, as they are associated with increased incidence of stent thrombosis, an efficient and prolonged post-PCI antiplatelet regimen is recommended.

Project description:BackgroundPerforation of the interventricular septum and left ventricular (LV) free wall by a right ventricular (RV) lead is an extremely rare and potentially life-threatening complication. In this case report, we discussed the diagnosis and management of a very unusual complication of pacemaker (PM) implantation, i.e., LV perforation brought on by an RV pacing lead.Case summaryA 92-year-old man was admitted to Xiangyang No.1 People's Hospital due to a complete atrioventricular block. We performed a dual-chamber PM implantation; however, on the second postoperative day (POD), pacemaker failure occurred. Thoracic computed tomography (CT) scan showed that RV lead had pierced the interventricular septum and LV free wall. A transvenous lead extraction of the penetrating lead was performed uneventfully, and RV lead was refixed at the lower RV septum on the 5th POD.DiscussionIdentification of high-risk patients is mandatory to prevent this serious complication, and transvenous lead extraction with cardiac surgery backup may be an option.
