Resolution of thrombus in left ventricular outflow tract pseudoaneurysm mimicking periaortic abscess.

ABSTRACT: Prosthetic valve complications are not uncommon after valve replacement. In this paper we report a female patient who presented with aortic prosthetic valve endocarditis and echocardiographic appearance of periaortic abscess. After 6 weeks of antibiotic therapy, echocardiographic examination revealed resolution of abscess cavity and replacement with a clear blood-filled anechoic sac. Diagnosis was made by cardiac computed tomography, which showed a left ventricular outflow tract (LVOT) pseudoaneurysm rather than an abscess, located just below the sewing ring of the prosthetic aortic valve. We assumed that either resolution of thrombus in LVOT pseudoaneurysm following effective warfarin therapy or clearance of infective content in pseudoaneurysm after co-administered antibiotics gave rise to change in echocardiographic characteristics in the perivalvular area.

Left Ventricular Outflow Tract Pseudoaneurysm Formation Following Three Aortic Valve Replacement Surgeries.

Project description:We present a case of a pseudoaneurysm arising from the left ventricular outflow tract/aortic root as a complication of aortic valve surgery. A 45-year-old Nigerian female presented to our institution's emergency department with chest discomfort. She had three bioprosthetic aortic valve replacements in the preceding year at an outside institution for aortic regurgitation and wanted a second opinion on remaining surgical options. The learning points relevant to this case are as follows: (1) Recognizing potential complications postmultiple valve surgeries, (2) screening patients for chronic infections and rheumatologic conditions that can contribute to failed valve surgeries.

Pseudoaneurysm in the left ventricular outflow tract after prosthetic aortic valve implantation: evaluation upon multidetector-row computed tomography.

Project description:The high accuracy of multidetector-row computed tomography (MDCT) in evaluating prosthetic valve disorders has been confirmed. This, we believe, is the 1st report of the use of MDCT to detect and evaluate left ventricular outflow tract (LVOT) pseudoaneurysms in patients who have undergone aortic valve replacement with prosthetic valves. We used MDCT to scan 21 such patients, 3 of whom had a small pseudoaneurysm in the LVOT. Each pseudoaneurysm projected away from the LVOT and had a narrow neck that was located just below the sewing ring of the prosthetic aortic valve. One pseudoaneurysm was not thrombotic, 1 was partially thrombotic, and 1 was completely thrombotic. One of these had gone undetected earlier on transthoracic echocardiography.We consider MDCT to be superior to echocardiography in the detection of LVOT pseudoaneurysms in patients who have undergone aortic valve replacement with prosthetic valves. We publicize our results in the hope that larger studies will be undertaken in order to investigate the prevalence and clinical implications of our findings.

Left ventricular outflow tract thrombus in a patient with COVID-19-a ticking time bomb: a case report.

Project description:BackgroundCoronavirus disease 2019 (COVID-19) is a manifestation of severe acute respiratory syndrome coronavirus 2, which results in many different complications including left ventricular (LV) thrombi.Case summaryWe present a 30-year-old female presenting with chest pain and shortness of breath. Patient had an extensive history including heart failure with an ejection fraction 15-20% and COVID-19 2 months ago. Echocardiogram revealed a 3.3 cm × 1.7 cm LV thrombus which was not present 4 months ago before her diagnosis of COVID-19. The LV thrombus embolized resulting in an embolus extending from the distal infrarenal abdominal aorta to the common iliac arteries bilaterally. Repeat COVID pre-procedure was positive. She underwent bilateral femoral artery cutdown, bilateral iliac artery embolectomy, superficial femoral artery embolectomy, and bilateral lower extremity fasciotomy. An extensive workup for the aetiology of the LV thrombus turned out to be negative and COVID-19 was deemed to be the aetiology of the thrombus. The patient was bridged from apixaban to warfarin and was successfully discharged within a few weeks.DiscussionHypercoagulability is a known complication of COVID-19 causing thrombi in various parts of the body including the LV. Early recognition with echocardiography, especially in patients with heart failure, and prompt treatment is key to avoid further complications such as embolization.

Innocent left ventricular outflow tract membrane masquerading as vegetation.

Project description:Innocent left ventricular outflow tract (LVOT) membranes are a rare entity and found incidentally on echocardiography. The authors report a case of innocent LVOT membrane in a patient who was admitted with ischaemic stroke. Initial transthoracic echocardiography showed a possible valvular vegetation which was thought to be the cause of embolic stroke. Anticoagulation with coumadin and antibiotics were started. Subsequent Transesophageal echocardiography showed that it was more consistent with innocent LVOT membrane and not vegetation. Anticoagulation and antibiotics were discontinued, and on a follow-up over 5 years later, the membrane was stable in size and location without any complications.

Transcatheter Closure of Left Ventricular Outflow Tract-to-Left Atrium Fistula.

Project description:Surgical and rarely transcatheter aortic valve replacement can be complicated by intracardiac fistula. Transcatheter closure of those shunts has been previously reported with favorable results. We describe a case of percutaneous closure of left ventricular outflow tract-to-left atrium fistula after surgical aortic valve replacement using an Amplatzer Vascular Plug II. (Level of Difficulty: Advanced.).

Transcatheter Exclusion of a Large Pseudoaneurysm of a Systemic Right Ventricular Outflow Tract.

Project description:We describe a rare patient with a large pseudoaneurysm of the right ventricular outflow tract that had developed after placement of a right ventricle-pulmonary artery conduit. A 7-mm Amplatzer Septal Occluder device was used to exclude the pseudoaneurysm, allowing for safer subsequent surgical repair. (Level of Difficulty: Advanced.).

An unusual cause of left ventricular outflow tract obstruction.

Project description:Left ventricular outflow tract obstruction (LVOTO) has been reported with bio-prosthetic and mechanical mitral valves (MV), though it is more common with the former. The obstruction can be dynamic or fixed. We hereby report a case of fixed LVOTO following bio-prosthetic MV replacement (MVR).
