Left ventricular mass: A tumor or a thrombus diagnostic dilemma.

Project description:Left ventricular (LV) mass is a rare condition, of which the most common is thrombus. Echocardiography is a very useful modality of investigation to evaluate the LV mass. We are reporting a case of LV mass presenting with neurological symptom. The diagnosis of this mass was dilemma as the echocardiographic features were favoring tumor as well as thrombi. Mass (a) measuring 3.8 cm × 1.9 cm attached to the left ventricle apex appeared to be pedunculated tumor and mass (b) measuring 2.4 cm × 1.8 cm attached to the chordae of anterior mitral leaflet resembled a thrombus or an embolized tumor entangled in the chordae. A differential diagnosis for the LV mass is thrombus, tumors such as fibroma, and vegetation. Preoperative detection of a thrombus leads to an alteration in surgical steps. A large and mobile thrombus with or without a hemodynamic alteration is an indication for surgical removal to prevent stroke, myocardial infarction, mesenteric ischemia, renal infarction, gangrene of the limbs, and mortality.

Intracardiac Echocardiogram: Feasibility, Efficacy, and Safety for Guidance of Transcatheter Multiple Atrial Septal Defects Closure.

Project description:We aimed to determine the feasibility, efficacy, success, and safety of intracardiac echocardiography (ICE) in transcatheter multiple atrial septal defect (ASD) closure. Of 185 patients with multiple ASDs who underwent transcatheter closure, 140 (76%) patients who weighed <30kg with a narrow distance between defects or in whom single device closure was anticipated were guided by ICE and 45 patients were guided by three-dimensional (3D) transesophageal echocardiography (TEE) with or without ICE. Patients in the ICE group were relatively younger and weighed less than those in the 3D TEE group (p < 0.0001). The ratio of the distance between defects >7 mm was high, and more cases required ≥2 devices in the 3D TEE group than those in the ICE group (p < 0.0001). All patients in the 3D TEE group and seven patients (5%) in the ICE group were operated on under general anesthesia (p < 0.0001). The fluoroscopic time was shorter in the ICE group (13.98 ± 6.24 min vs. 24.86 ± 16.47 min, p = 0.0005). No difference in the complete closure rate and complications was observed. ICE-guided transcatheter and 3D TEE were feasible, safe, and effective in successful multiple ASD device closures, especially for young children and patients at high risk under general anesthesia.

Mobile Intracardiac Mass after Inguinal Hernia Repair: An Unresolved Treatment Dilemma.

Project description:Right heart thrombi (RHT) are rare but well-described entity in literature. Their isolation has been considered as confirmatory for the diagnosis of venous thromboembolism (VTE). Even though their isolation aids the diagnosis, physicians are faced with a difficult management dilemma giving the paucity of data to support any treatment decision. We present a case of RHT in an 81-year-old man who presented to hospital with a large mobile right heart thrombus in transit seen on transthoracic echocardiogram (TTE). He was successfully treated with anticoagulation alone. This case highlights the importance of TTE in establishing the diagnosis and describes the interplay of factors influencing treatment decision.

Diagnostic challenges of recurrent left atrial mass: a case report

Project description:Abstract Background Differential diagnosis of left atrial (LA) masses is challenging because there is a significant overlap in the epidemiological, clinical, and imaging characteristics. Even some histological features can be similar across different types of cardiac masses. Therefore, continuous case discussion between the clinician and the pathologist is essential for a correct diagnosis. Case summary We present a case of a patient with a history of cardiac surgery for LA tumour. Histology was compatible with thrombus, although no predisposing causes nor genetic or acquired thrombophilia were identified. After 14 years, the recurrence of LA mass was diagnosed with a routine echocardiography. A review of histological preparations from 2007 with immunohistochemistry techniques not available at that time (calretinin) was consistent with a myxoma. The patient underwent cardiac reoperation with LA mass and interatrial septum excision. Final diagnosis was compatible with a myxoma recurrence. Discussion Myxoma is the second most frequent benign primary cardiac tumour. Left atrial thrombi can occasionally mimic the typical echocardiographic appearance of a myxoma, and pathological features can sometimes overlap generating diagnostic confusion. Calretinin fixation is useful for differential diagnosis once it is only identified in myxomas but not in thrombi. Any discrepancy between clinical findings and histology should always mandate a review of histological preparations.

Large Cystic Intracardiac Mass Overlying Left Atrial Appendage Occlusion Device: A Case Report and Literature Review

Project description:Graphical abstract Highlights • The Watchman device is a possibility for patients with an elevated risk of stroke or bleeding.• Device-related infection is extremely uncommon.• Patient screening and selection prior to Watchman implantation are of vital importance.• Device-related infection is related to peri-implantation bacteremia or inadequate sterility.

Left atrial appendage closure with the Watchman device using intracardiac vs transesophageal echocardiography: Procedural and cost considerations.

Project description:BackgroundImaging guidance for left atrial appendage (LAA) closure (LAAC) conventionally consists of transesophageal echocardiography (TEE) and fluoroscopy under general anesthesia (GA). Intracardiac echocardiography (ICE) can eliminate the need for GA, expedite procedural logistics, and reduce the patient experience to a simple venous puncture.ObjectiveThe purpose of this study was to define optimal ICE views and compare procedural parameters and cost of ICE vs TEE during LAAC with the Watchman device.MethodsOptimal ICE views of the LAA for Watchman implant were delineated using Carto-Sound and 3-dimensional rendition of the LAA in 6 patients. Procedural and financial parameters of 104 consecutive patients with standard indications for LAAC undergoing Watchman implant using ICE guidance through a single transseptal puncture (n = 53 [51%]) were compared with those of TEE-guided implants (n = 51 [49%]) in 3 centers.ResultsClinical characteristics were similar between the 2 groups. Total in-room, turnaround, and fluoroscopy times all were shorter using ICE (P <.05) under local anesthesia compared to the TEE group. Implant success was 100% in both groups without peri-device leaks or procedural complications. Follow-up TEE showed no significant peri-device leak in both groups. Total hospital charges for ICE with local anesthesia vs TEE were similar, as were total hospital direct and indirect costs. Professional fees were significantly lower with ICE and local anesthesia than with TEE because the charge of anesthesia staff was avoided.ConclusionICE-guided Watchman implant is safe, feasible, and comparable in cost to TEE during LAAC with a Watchman device but avoids GA and expedites procedure turnaround.
