Different CMR Imaging Modalities for Native and Patch-Repaired Right Ventricular Outflow Tract Sizing: Impact on Percutaneous Pulmonary Valve Replacement Planning

AbstractPercutaneous pulmonary valve replacement (PPVI) in native or patched right ventricular outflow tract (RVOT) has proven to be feasible. The procedure is highly dependent on the size of the RVOT. Several methods exist to evaluate the size of the RVOT by cardiovascular magnetic resonance (CMR). We evaluated different CMR modalities for measuring RVOT diameters. Thirty-one consecutive patients with native or patched RVOT were retrospectively evaluated. CMR was part of follow-up of patients with corrected Tetralogy of Fallot or pulmonary stenosis with significant pulmonary regurgitation (PR). CMR included 3D-SSFP whole-heart in systole, diastole, and contrast-enhanced MR angiography (ceMRA). Diameters of the RVOT were assessed by the three sequences. Additionally, in patients who underwent cardiac catheterization (n = 11) for PPVI, vessel diameters assessed by cine-angiography were compared to CMR. Systolic diameters of RVOT were significantly larger compared to the diameters taken in diastole and ceMRA (median difference 5.0 mm and 3.8 mm). Diastolic and ceMRA diameters did not differ significantly. CMR diameters taken in systole showed no statistical difference to systolic diameters taken by cine-angiography, while diastolic and ceMRA diameters were significantly smaller. PPVI was feasible to a maximal CMR diameter of 31 mm measured by SSFP whole-heart sequence in systole. Absolute diameters of native RVOT differ depending on the CMR sequence...

Abstract Cardiac papillary fibroelastoma are rare, benign cardiac tumors that may lead to lethal complications from embolization or valvular dysfunction if left untreated. When working up symptomatic tumors with concomitant angina, traditional diagnostic studies such as cardiac catheterization may predispose the patient to embolic complications if the mass is located in the path of the catheter. Newer, non-invasive diagnostic testing, such as cardiac magnetic resonance imaging or dynamic computed tomography angiography, may be considered in lieu of invasive approaches to avoid potentially devastating complications. We here...

Perventricular VSD closure  Perventricular VSD closure is a hybrid procedure in which the cardiac surgeon opens the chest and the cardiologist passes a sheath through the right ventricle to achieve a device closure of the ventricular septal defect (VSD). Hybrid procedures are done in hybrid suites with facility for both open heart surgery and radiographic equipment for cardiac catheterization and angiography (hybrid of open heart surgery theatre and cardiac catheterization laboratory or cathlab). Heart is exposed through a lower partial sternotomy. The advantage is that cardiopulmonary bypass is n...

AbstractObjectivesTo evaluate the in vivo feasibility of aortography with one accurately timed diastolic low ‐volume contrast injection for quantitative assessment of aortic regurgitation (AR) post transcatheter aortic valve replacement (TAVR).BackgroundWith the rise of a minimalistic approach for TAVR, aortography (re)emerges as a pragmatic tool for AR assessment. In a mock circulation system, we have validated the accuracy of a single diastolic injection triggered by electrocardiogram (ECG) with low ‐contrast volume.MethodsTwo ‐phase experiment: first, a series of aortograms were performed in a porcine model, with ...

Abstract Experience with cardiac magnetic resonance to evaluate coronary arteries in children and young adult patients is limited. Because noninvasive imaging has advantages over coronary angiography, we compared the effectiveness of these techniques in patients who were being considered for percutaneous pulmonary valve implantation. We retrospectively reviewed the cases of 26 patients (mean age, 12.53 ± 4.85 yr; range, 5-25 yr), all of whom had previous right ventricular-to-pulmonary artery homografts. We studied T2-prepared whole-heart images for coronary anatomy, velocity-encoded cine images for ventricu...

In conclusion, CAD is prevalent in TAVR patients and pre‐TAVR coronary revascularization is typically focused on treating proximal and high‐grade stenosis. A selective pre‐TAVR PCI strategy results in favorable clinical outcomes with very low rates of post‐TAVR coronary revascularization.

Conclusions The number of diagnostic and therapeutic procedures in acute myocardial infarction increased in 2016. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The growing trend observed in previous years continued for the use of transcatheter aortic prosthesis, the MitraClip device, and left atrial appendage closure.

Abstract ObjectivesWe sought to investigate the possible impact of transaortic valve replacement (TAVR) on common femoral artery (CFA) integrity as assessed by angiography. BackgroundCFA represents the most adopted access for TAVR but various degrees of vascular damage may be induced by the procedure. MethodsPatients underwent percutaneous transfemoral TAVR who had both pre‐ and post‐TAVR access‐site angiography were retrospectively selected. Clinical and procedural data (including technique and complications) were prospectively recorded into a structured TAVR database. Pre‐TAVR and post‐TAVR angiograms were anal...
