Rapid and Accurate Registration Method between Intraoperative 2D XA and Preoperative 3D CTA Images for Guidance of Percutaneous Coronary Intervention.

Rapid and Accurate Registration Method between Intraoperative 2D XA and Preoperative 3D CTA Images for Guidance of Percutaneous Coronary Intervention. Comput Math Methods Med. 2019;2019:3253605 Authors: Park T, Koo K, Shin J, Lee J, Kim KW Abstract In this paper, we propose a rapid rigid registration method for the fusion visualization of intraoperative 2D X-ray angiogram (XA) and preoperative 3D computed tomography angiography (CTA) images. First, we perform the cardiac cycle alignment of a patient's 2D XA and 3D CTA images obtained from a different apparatus. Subsequently, we perform the initial registration through alignment of the registration space and optimal boundary box. Finally, the two images are registered where the distance between two vascular structures is minimized by using the local distance map, selective distance measure, and optimization of transformation function. To improve the accuracy and robustness of the registration process, the normalized importance value based on the anatomical information of the coronary arteries is utilized. The experimental results showed fast, robust, and accurate registration using 10 cases, each of the left coronary artery (LCA) and right coronary artery (RCA). Our method can be used as a computer-aided technology for percutaneous coronary intervention (PCI). Our method can be applied to the study of other types of vessels.

Rationale: Transradial access (TRA) is a widely used technique during percutaneous coronary intervention (PCI). However, mediastinal and cervical hematomas, the rare and severe complications of transradial approach, have extremely high mortality rates. To the best of our knowledge, there were no medical literatures about the successful anticoagulation reversal procedure of mediastinal hematoma in PCI till now. Patient concerns: We here present a 54-year-old male Han patient who underwent PCI. Immediately after PCI, he reported an episode of neck and chest discomfort, dyspnea, cough recurrence, and cold sweats. Emergen...

AbstractPurpose of ReviewThe purpose of this review is to evaluate the role of coronary computed tomography angiography (CCTA) in the assessment of patients after coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI).Recent FindingsAdvances in CT technology have resulted in tremendous improvements in diagnostic performance, safety, and ease of performance. CCTA accurately detects graft stenosis or occlusion. However, assessment of native coronary arteries in patients after CABG is challenging due to commonly present severe coronary calcifications. CCTA evaluation of coronary stents using c...

Abstract With more than 800,000 coronary artery bypass grafting (CABG) operations annually worldwide and the saphenous vein being the most common conduit used, there is no question that improving saphenous vein graft patency is one of the most important tasks in CABG. This video describes the no-touch harvesting procedure of the saphenous vein on an 80-year old man with hypertension, hyperlipidemia and a previous myocardial infarction with percutaneous coronary intervention to the right coronary artery. He was complaining of exertional chest pain and was diagnosed with stable angina pectoris. The coronary angiography showe...

CONCLUSION: The lower cost, higher sensitivity and specificity rates, and faster, less burdensome process for detecting CAD patients make Fast-SENC a more capable and economically beneficial stress test than SPECT. The payer model and hospital model demonstrate an alignment between payer and provider economics as Fast-SENC provides monetary savings for patients and resource benefits for hospitals.

Authors: Lee SH, Lee JM, Song YB, Park TK, Yang JH, Hahn JY, Choi SH, Gwon HC, Lee SH, Kim SM, Choe YH, Choi JH Abstract AIMS: Side branch (SB) occlusion is one of the major technical hurdles in the percutaneous coronary intervention (PCI) of bifurcation lesion. We investigated whether preprocedural coronary computed tomography angiography (CCTA) could predict intraprocedural SB occlusion. METHODS AND RESULTS: A total of 260 bifurcation lesions were enrolled from 246 patients who underwent CCTA before elective PCI for bifurcation lesion. Quantitative plaque analysis was done in both main vessel (MV) and SB. Int...

Authors: Arao K, Mase T, Nakai M, Sekiguchi H, Abe Y, Kuroudu N, Oobayashi O Abstract A 71-year-old man presented to our hospital for dyspnea lasting for the past 3 days. Chest X-ray and computed tomography demonstrated right tension pneumothorax, and an electrocardiogram suggested acute inferior myocardial infarction. Despite the relief of tension pneumothorax, the electrocardiographic findings were not completely resolved. Emergency coronary angiography demonstrated an occlusive lesion in the right coronary artery, and percutaneous coronary intervention was performed successfully. Thereafter, the chest tube was r...

Rationale: Coronary perforation leading to fistula directed to the right ventricle is a rare complication of percutaneous coronary intervention (PCI). The reported outcomes vary from a stable state to rapid deterioration. Patient concerns: An 86-year-old man was diagnosed with non-ST elevation myocardial infarction, and arranged to PCI procedure for the chronic total occluded right coronary artery (RCA) after coronary angiography. The guide wire went through the occluded lesion and got to the distal part of the suspected “post lateral artery”, which later proved to be in the right ventricle (RV). After dil...
