Conservative approach of ascending aortic dissection after transcatheter aortic valve replacement: A case report.

Transcatheter aortic valve replacement (TAVR) has shown good early and midterm results from high risk to low surgical risk patients with severe symptomatic aortic valve stenosis. Despite low adverse events, TAVR is associated with vascular injury, bleeding, stroke, and conduction system disturbances as the most common adverse events. Aortic dissection is a relatively rare but potentially lethal complication from TAVR.

Early and Mid-Term Outcomes of Femoro-Ilio-Caval Vein Stent Implantation.

Objective: We sought to investigate mid-term clinical outcomes and identify risk factors in one of the largest comprehensive series reported of femoro-ilio-caval (FIC) vein stent placement.

Background: Endovascular intervention with balloon angioplasty and stenting of the iliac and common femoral veins has become first-line treatment for symptomatic deep venous outflow obstruction.

Methods: We conducted a single-center, retrospective analysis of 180 patients who underwent FIC stent implantation between May 2017 and May 2019; 327 procedures were performed.

The Hybrid Coronary Approach for Optimal Revascularization: JACC Review Topic of the Week.

Coronary revascularization is accomplished either by percutaneous coronary intervention (PCI), with low risk of immediate complications, or coronary artery bypass graft (CABG), with improved long-term, event-free survival attributable to use of the left internal mammary artery graft. Hybrid coronary revascularization (HCR) combines both. The left internal mammary artery graft is done by sternal-sparing approaches or by robotic-assisted, endoscopic surgery.

Myocardial Amyloid Quantification with Look-Locker Magnetic Resonance Sequence in Cardiac Amyloidosis. Diagnostic Accuracy in Clinical Practice and Histological Validation.

Background: Cardiac magnetic resonance (CMR) has demonstrated its utility in the noninvasive diagnosis of cardiac amyloidosis (CA). Our aim was to evaluate the ability of standard Look-Locker sequences to quantify amyloid deposition in CA.

Methods And Results: Consecutive patients referred for CMR for possible CA were retrospectively evaluated.

Blood Pool Segmentation Results in Superior Virtual Cardiac Models than Myocardial Segmentation for 3D Printing.

The method of cardiac magnetic resonance (CMR) three-dimensional (3D) image acquisition and post-processing which should be used to create optimal virtual models for 3D printing has not been studied systematically. Patients (n = 19) who had undergone CMR including both 3D balanced steady-state free precession (bSSFP) imaging and contrast-enhanced magnetic resonance angiography (MRA) were retrospectively identified. Post-processing for the creation of virtual 3D models involved using both myocardial (MS) and blood pool (BP) segmentation, resulting in four groups: Group 1-bSSFP/MS, Group 2-bSSFP/BP, Group 3-MRA/MS and Group 4-MRA/BP.

Use of a Three Dimensional Printed Cardiac Model to Assess Suitability for Biventricular Repair.

Three dimensional (3D) printing is rapidly gaining interest in the medical field for use in presurgical planning. We present the case of a seven-year-old boy with double outlet right ventricle who underwent a bidirectional Glenn anastomosis. We used a 3D cardiac model to assess his suitability for a biventricular repair.

Thrombosed cor triatriatum sinistrum mimicking left atrial mass and causing unilateral pulmonary edema.

46 year old female with history of progressive shortness of breath for 3 years associated with recurrent right lung infiltrates and hemoptisis. A computed tomography of the chest showed a left atrial mass suggestive of atrial myxoma confirmed with transesophageal echocardiogram. Contrary with findings from a dedicated EKG gated cardiac computed tomography suggestive of cor triatriatum with associated thrombus and less likely a neoplasm; findings later on confirmed during surgery.

Anomalous hepatic vein drainage into a giant left atrium.

A 56-year-old man with a history of complex atrial-septal defect repair, atrial fibrillation, and severe mitral regurgitation presented with progressive shortness of breath. A cardiac CT examination was done as part of a preoperative protocol before mitral valve replacement and it showed a severely enlarged left atrium and an anomalous hepatic vein draining into the left atrium. These findings were totally unsuspected and changed the patient management, highlighting the benefit of cardiac CT beyond the coronary finding.
