Percutaneous closure of left ventricular pseudoaneurysm using simultaneous transseptal and transapical approach: a case report.

ABSTRACT:

Background

Left ventricular (LV) pseudoaneurysm (PSA), also referred to as contained LV wall rupture, is a clinically uncommon but potentially life-threatening condition that can occur after myocardial infarction or cardiac surgery. If the anatomic characteristics of LV PSA are not eligible for the transfemoral approach, percutaneous closure of LV PSA can be technically difficult and appropriate approach selection may contribute to procedural success.

Case summary

An enlarging LV PSA was discovered in a 65-year-old man with Marfan syndrome and three prior cardiothoracic surgeries. Arterial access was not possible due to invagination of the previously placed surgical graft in the descending thoracic aorta. This was managed with a novel approach of simultaneous transseptal LV access and direct puncture of PSA through the chest wall followed by a vascular plug placement.

Discussion

This case demonstrates that percutaneous LV PSA closure using a hybrid approach of transseptal and direct apical puncture is a feasible and effective alternative for high-risk surgical candidates, although the anatomic characteristics are unsuitable for the transfemoral approach.

Percutaneous closure of an uncommon aortic pseudoaneurysm after arterial switch repair: a case report.

Project description:BackgroundThe development of an aortic pseudoaneurysm is a rather rare but potentially fatal complication after cardiac surgery for aortic valve and aorta disease. If a pseudoaneurysm is left untreated, it carries a substantial risk of rupture, thrombosis with subsequently systemic embolization, and compression of the surrounding structures.Case summaryWe describe a case of a transcatheter repair of a more complex and uncommon pseudoaneurysm following aortic valve replacement in a patient with a history of arterial switch repair for transposition of the great arteries. The pseudoaneurysm originated from the aortic wall and connected to the left ventricular outflow tract (LVOT). The connection to LVOT was closed with a duct occluder, the neck to the aortic wall with an atrial septal defect occluder. After 1 month, the complete pseudoaneurysm was successfully thrombosed.DiscussionPercutaneous closure of a complex pseudoaneurysm after arterial switch repair is feasible and safe. However, lifelong follow-up is needed to determine the late results after transcatheter interventions.

Left ventricular pseudoaneurysm complicating inferior myocardial infarction: a case report.

Project description:Acquired pseudoaneurysm of the left ventricle is a very rare disorder and mostly occurs after large transmural myocardial infarction (MI) with peak creatine phosphokinase-MB levels greater than 150 IU/mL. Patients developing left ventricular (LV) pseudoaneurysm usually present with angina or heart failure symptoms. Although different imaging modalities exist, coronary angiography is the gold standard for diagnosis. Surgery is the treatment of choice for LV pseudoaneurysms detected in the first months after MI. Here we report the case of a 74-year-old woman who presented with a relatively small inferior MI due to right coronary artery occlusion and complicated by LV pseudoaneurysm.

Direct percutaneous left ventricular access and port closure: pre-clinical feasibility.

Project description:OBJECTIVES:This study sought to evaluate feasibility of nonsurgical transthoracic catheter-based left ventricular (LV) access and closure. BACKGROUND:Implanting large devices, such as mitral or aortic valve prostheses, into the heart requires surgical exposure and repair. Reliable percutaneous direct transthoracic LV access and closure would allow new nonsurgical therapeutic procedures. METHODS:Percutaneous direct LV access was performed in 19 swine using real-time magnetic resonance imaging (MRI) and an "active" MRI needle antenna to deliver an 18-F introducer sheath. The LV access ports were closed percutaneously using a commercial ventricular septal defect occluder and an "active" MRI delivery cable for enhanced visibility. We used "permissive pericardial tamponade" (temporary fluid instillation to separate the 2 pericardial layers) to avoid pericardial entrapment by the epicardial disk. Techniques were developed in 8 animals, and 11 more were followed up to 3 months by MRI and histopathology. RESULTS:Imaging guidance allowed 18-F sheath access and closure with appropriate positioning of the occluder inside the transmyocardial tunnel. Of the survival cohort, immediate hemostasis was achieved in 8 of 11 patients. Failure modes included pericardial entrapment by the epicardial occluder disk (n = 2) and a true-apex entry site that prevented hemostatic apposition of the endocardial disk (n = 1). Reactive pericardial effusion (192 ± 118 ml) accumulated 5 ± 1 days after the procedure, requiring 1-time drainage. At 3 months, LV function was preserved, and the device was endothelialized. CONCLUSIONS:Direct percutaneous LV access and closure is feasible using real-time MRI. A commercial occluder achieved hemostasis without evident deleterious effects on the LV. Having established the concept, further clinical development of this approach appears realistic.

Percutaneous closure of accidental left atrium puncture: a case report.

Project description:BackgroundMinimally invasive alternatives to surgical closure of cardiac perforations are a recognized need, especially in critically ill patients in whom predicted surgical mortality is prohibitive. To the best of our knowledge, this is the first reported case of an iatrogenic left atrium (LA) puncture closed with a plug-based vascular closure device (VCD).Case summaryDuring a palliative right-sided thoracentesis on a 73-year-old woman, with end-stage heart failure due to rheumatic valvular heart disease, an accidental puncture and insertion of a central venous catheter into an aneurysmatic LA occurred. This complication was successfully managed percutaneously, under transthoracic echocardiographic guidance, after cardiac computed tomography planning, using a plug-based VCD.DiscussionThis case demonstrates the possible utility of plug-based devices for iatrogenic LA perforation closure, when surgical risk is deemed prohibitive.

Left ventricular pseudoaneurysm: an inadvertent consequence of COVID-19-a case report.

Project description:BackgroundLeft ventricular pseudoaneurysm (LVP) is an uncommon but serious mechanical complication of acute myocardial infarction (AMI). The immediate medical complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are well recognized, but its indirect effect on patients and healthcare systems is potentially less perceivable.Case summaryIn this report, a 72-year-old man who was anxious about attending hospital during the SARS-CoV-2 pandemic was eventually found to have a total right coronary artery occlusion after a delayed emergency department presentation. He ultimately developed severe symptomatic heart failure and cardiac magnetic resonance imaging (CMR) revealed that a large LVP with concomitant severe ischaemic mitral regurgitation had evolved from his infarct. The patient was successfully discharged home after the surgical replacement of his mitral valve and repair of his LVP.DiscussionThis case highlights a salient downstream effect of Coronavirus disease 2019 (COVID-19): the delay in presentation, diagnosis, and management of common treatable conditions such as AMI. It also underscores the importance of non-invasive multimodal imaging on the timely identification of the mechanical complications of AMI. In particular, CMR can play a crucial role in the characterization and management of LVP.

Case Report: Delayed Ventricular Pseudoaneurysm After Radiofrequency Ablation of Left Posteromedial Papillary Muscle Ventricular Tachycardia.

Project description:A 74-year-old woman presented with incessant wide complex tachycardia that was refractory to cardioversions. Successful radiofrequency catheter ablation was performed on the left ventricular posteromedial papillary muscle. An inaudible steam pop has occurred during the procedure, but we confirmed that there were no complications during the procedure and short-term follow-up of echocardiography. Two months after the procedure, an asymptomatic pseudoaneurysm was identified at the ablation site that had not been observed in the short-term follow-up.

Management of ascending aorta perforation during transseptal puncture for left atrial appendage closure: a case report.

Project description:BackgroundAn 82-year-old female with a history of atrial fibrillation and repeated episodes of major bleeding on direct oral anticoagulant therapy, with a high risk for thromboembolism and was referred for left atrial appendage closure.Case summaryDuring the procedure, an unrecognized puncture of the aorta by the transseptal puncture (TSP) needle and inadvertent advancement of the sheath resulted in ascending aorta perforation. This perforation was closed percutaneously using an Amplatzer™ Duct Occluder (ADO). Reversal of heparinization with protamine sulphate was given to avoid intractable bleeding. However, this resulted in thrombus formation and subsequent embolization causing an ST-elevation myocardial infarction. This was treated with balloon dilatation and thrombus aspiration with subsequent Thrombolysis in Myocardial Infarction 3 flow.DiscussionInadvertent ascending aorta perforation is a rare yet serious complication that can occur during TSP. Percutaneous closure using an ADO is a viable management option. The reversal of heparin carries a risk of thrombus formation and should be avoided in cases where there is no evidence of overt bleeding.

Case report: percutaneous closure of residual leak following left atrial appendage occlusion.

Project description:BackgroundTranscatheter left atrial appendage occlusion (LAAO) using Watchman device has been demonstrated to be efficacious in decreasing stroke risk in patients with atrial fibrillation who are not suitable for long-term anticoagulation. Residual leaks are frequently encountered following LAAO procedures and their clinical implications and optimal management remain controversial.Case summaryIn this report, we describe a case of peri-Watchman device leak treated successfully with percutaneous device closure using an Amplatzer Vascular Plug II device.DiscussionThe clinical implications of peri-device leaks remain controversial with general consensus to continue anticoagulation along with serial imaging for larger leaks (>5 mm). As an alternative strategy, percutaneous closure of these leaks has been attempted in hope of avoiding anticoagulation and minimizing the risk of stroke and should be studied further.
