Myxoma Involving the Pulmonary Valve - A Case Report of an Atypical Cardiac Tumor, Treated Using an Unusual Approach.

Background: Atypical myxoma has been reported in various locations in the heart, however, myxoma involving the pulmonary valve is rare. Here we present a case of pulmonic valve myxoma which was resected via a percutaneous approach.

Case Report: A 66-year-old female with known metastatic adenocarcinoma of the lung, and chronic obstructive pulmonary disease presented with acute onset shortness of breath for two days.

Impact of magnetic resonance imaging on functional integrity of non-conditional cardiovascular implantable electronic devices.

Background: Cardiovascular implantable electronic devices (CIEDs) have historically restricted the use of magnetic resonance imaging (MRI) due to the potential clinical and configurational risks associated with electromagnetic interference. In this study, the authors investigated the impact of MRI on the functional integrity of non-conditional CIEDs and their clinical correlates.

Methods: In this prospective, observational single-center study, we enrolled patients undergoing MRI over a 5-year period.

Where do we go from here? Beyond the MagnaSafe trial: A focus beyond a 'safety-first' notion. An MRI study in 500 consecutive patients.

Background: In patients with conventional pacemakers or ICD's, MRI is infrequently performed due to safety concerns. Recent reports have allayed many of these concerns. However, the additive clinical value of scanning patients with cardiac implants has not been established.

Redefining the fluoroscopic landmarks for common femoral arterial puncture during cardiac catheterization: Femoral angiogram and computed tomography angiogram (FACT) study of common femoral artery anatomy.

Background: The mid-femoral head (F ) is a common fluoroscopic target for common femoral artery (CFA) puncture during cardiac catheterization. Punctures above the inguinal ligament (marking the proximal end of CFA) increase the risk of retroperitoneal hemorrhage and are classified as high punctures.

Methods: We retrospectively analyzed 114 CT angiograms for the anatomic relationship of the inguinal ligament to the femoral head (FH) and inferior epigastric artery (IEA).

Diagnostic Value of MRI in Patients With Implanted Pacemakers and Implantable Cardioverter-Defibrillators Across a Cross Population: Does the Benefit Justify the Risk? A Proof of Concept Study.

Objectives: The objective of this study was to assess the diagnostic usefulness of thoracic and nonthoracic magnetic resonance imaging (MRI) imaging in patients with implantable cardiac devices (permanent pacemaker or implantable cardioverter-defibrillators [ICDs]) to determine if there was a substantial benefit to patients with regard to diagnosis and/or management.

Background: MRI is infrequently performed on patients with conventional pacemakers or ICDs. Multiple studies have documented the safety of MRI scans in patients with implanted devices, yet the diagnostic value of this approach has not been established.

Echocardiography and cardiovascular MRI entwined within the imaging domain; uniting the two. A compendium for the echocardiographer.

A review of the unique and complementary roles echocardiography and cardiovascular MRI provide to the clinician. A focus on the physics of each modality as well as imaging of the left ventricle.

Cardio-hepatic risk assessment by CMR imaging in liver transplant candidates.

Background: The preoperative workup of orthotopic liver transplantation (OLT) patients is practically complex given the need for multiple imaging modalities. We recently demonstrated in our proof-of-concept study the value of a one-stop-shop approach using cardiovascular MRI (CMR) to address this complex problem. However, this approach requires further validation in a larger cohort, as detection of hepatocellular carcinoma (HCC) as well as cardiovascular risk assessment is critically important in these patients.

Type I Kounis syndrome variant: A case report and literature review.

Kounis syndrome defined as the occurrence of acute coronary syndrome in the setting of allergic reaction due to mast cells activation and inflammatory mediators release that induces coronary vasospasm, plaque erosion, or even stent thrombosis. A 25-year-old postpartum female with asthma and recurrent episodes of chest pain was admitted with ST-segment elevation myocardial infarction in the setting of coronary artery spasms. The patient was started on calcium channel blockers and nitrite-based medication with no improvement.

Does Late Gadolinium Enhancement still have Value? Right Ventricular Internal Mechanical Work, E/E and Late Gadolinium Enhancement as Prognostic Markers in Patients with Advanced Pulmonary Hypertension via Cardiac MRI.

Objectives: Investigate the impact of Right Ventricular (RV) Internal Work (IW), ratio of arterial to ventricular end-systolic elastance (E/E), and RV Insertion Point (IP) Late Gadolinium Enhancement (LGE) on outcome in Pulmonary Hypertension (PH) patients.

Background: LGE is well known to be present within the RVIPs and Inter Ventricular Septum (IVS) in PH patients, but its prognostic role remains complex and potentially overestimated via 2D qualitative relative to the 3D quantitative measures now available. However, E/E, a measure of ventricular-arterial coupling and IW, when added to external cardiac work i.

Mid wall fibrosis on CMR with late gadolinium enhancement may predict prognosis for LVAD and transplantation risk in patients with newly diagnosed dilated cardiomyopathy-preliminary observations from a high-volume transplant centre.

Background: Patients with newly diagnosed dilated cardiomyopathy (DCM) and advanced heart failure have a very high morbidity and mortality with an unpredictable clinical course. We investigated the role of cardiovascular magnetic resonance (CMR) imaging using late gadolinium enhancement (LGE) in this cohort of high-risk patients. We hypothesized that LGE has high prognostic value in primary DCM patients referred for possible transplantation/left ventricular assist device (LVAD) consideration.

Incidental left atrial blood cyst in a patient undergoing transcatheter aortic valve replacement.

Blood cysts of the heart are benign cardiovascular tumors found incidentally in approximately 50% of infants who undergo autopsy at less than 2 months of age. These congenital cysts, frequently present on the atrioventricular valves of infants, are exceedingly rare in adults. Nonetheless, in adults, cardiac blood cysts have been found on the mitral valve, papillary muscles, right atrium, right ventricle, left ventricle, and aortic, pulmonic, and tricuspid valves.

Evaluation of cardiac valvular regurgitant lesions by cardiac MRI sequences: comparison of a four-valve semi-quantitative versus quantitative approach.

Background And Aim Of The Study: Cardiac magnetic resonance (CMR) imaging generally allows a more accurate and valid quantification of cardiac function, mass and regurgitant volumes than echocardiography. Although recent technological advancements in CMR have made the evaluation of cardiac valves more reliable, no studies have yet been conducted to compare semi-quantitative grading (SQG) using CMR steady-state free precession (SSFP) sequences with quantitative grading (QG) based on stroke volumes and phase-velocity mapping (PVM). It is proposed that the SQG of cardiac valvular regurgitations based on CMR SSFP sequences is feasible, and highly correlative with standard CMR QG methods.

Exploratory use of cardiovascular magnetic resonance imaging in liver transplantation: a one-stop shop for preoperative cardiohepatic evaluation.

Background: Preoperative cardiovascular risk stratification in orthotopic liver transplantation candidates has proven challenging due to limitations of current noninvasive modalities. Additionally, the preoperative workup is logistically cumbersome and expensive given the need for separate cardiac, vascular, and abdominal imaging. We evaluated the feasibility of a "one-stop shop" in a magnetic resonance suite, performing assessment of cardiac structure, function, and viability, along with simultaneous evaluation of thoracoabdominal vasculature and liver anatomy.

Mitral regurgitation recovery and atrial reverse remodeling following pulmonary vein isolation procedure in patients with atrial fibrillation: a clinical observation proof-of-concept cardiac MRI study.

Background: Reverse remodeling of the left atrium (LA) following successful pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF) has been well documented. However, mitral regurgitation (MR) recovery after successful PVI has never been demonstrated systematically. The objective of our study was to retrospectively analyze the effectiveness of PVI in patients with AF on recovery of MR using cardiac magnetic resonance (CMR) imaging.

Pericardial effusion masquerading as an aortic dissection.

A 24-year-old woman with a history of recurrent syncope underwent an echocardiogram that was suspicious for an ascending aortic dissection. Cardiac magnetic resonance imaging was performed which showed no evidence of aortic dissection. However, it did demonstrate a pericardial effusion that extended to the aortic arch.
