The Yin-Yang Sign of Severe Mitral Regurgitation
J Invasive Cardiol. 2021 Apr;33(4):E314.ABSTRACTIn select patients with severe, eccentric mitral regurgitation, we have observed that the regurgitant jet may entrain blood along the left atrial wall to produce a Chinese yin-yang symbol on color Doppler. This clinical imaging series demonstrates this unique phenomenon in an 81-year-old woman with symptomatic, severe, functional mitral regurgitation secondary to non-ischemic cardiomyopathy who was referred for transcatheter mitral valve repair. The yin-yang symbol resolved on transthoracic echocardiography after placement of 2 MitraClip NTR devices.PMID:33794480 (Source: The...

Successful Mechanical Aspiration of Embolized Vessel Fragment During TAVR With Penumbra Indigo Cat Rx Catheter
J Invasive Cardiol. 2021 Apr;33(4):E315.ABSTRACTAn 81-year-old female with severe aortic valve stenosis underwent TAVR using the right femoral approach. Shortly after successful deployment of a 29 mm Evolut Pro valve (Medtronic), the patient became hypotensive and ST depressions were noted on telemetry. Selective left coronary angiography revealed coronary embolism to the left anterior descending/ first diagonal bifurcation. Mechanical aspiration was performed and a small piece of debris was retrieved. We believe it was a broken-off fragment of the femoral artery that migrated on the tip of the TAVR delivery system. This i...

Mitral Valve Surgery After Failed MitraClip: A Single-Center Experience
CONCLUSION: When performed by an experienced mitral surgeon and within 1 year of failed MitraClip implantation, surgical MV repair is feasible in most patients who were surgical repair candidates before the clip. Having the option for surgical MV repair after failed MitraClip is important to preserve optimal long-term outcomes for patients who undergo transcatheter mitral repair with MitraClip, especially as ongoing trials are shifting to study lower-risk patients who are also candidates for surgical repair.PMID:33794477 (Source: The Journal of Invasive Cardiology)

Evaluation of a Real-World In-Hospital Antiplatelet-Switching Strategy Following Coronary Interventions: The SWITCH Study
CONCLUSIONS: A strategy of using newer, fast-acting, and reliable antiplatelet agents prior to PCI and acutely switching to long-term clopidogrel therapy appears safe and efficacious. Although the superiority of the newer antiplatelet agents for long-term post-PCI dual-antiplatelet therapy in a trial setting is well established, the impact of increased adherence to lower-cost clopidogrel therapy in the real-world setting merits further consideration.PMID:33794478 (Source: The Journal of Invasive Cardiology)

Successful Mechanical Aspiration of Embolized Vessel Fragment During TAVR With Penumbra Indigo Cat Rx Catheter
J Invasive Cardiol. 2021 Apr;33(4):E315.ABSTRACTAn 81-year-old female with severe aortic valve stenosis underwent TAVR using the right femoral approach. Shortly after successful deployment of a 29 mm Evolut Pro valve (Medtronic), the patient became hypotensive and ST depressions were noted on telemetry. Selective left coronary angiography revealed coronary embolism to the left anterior descending/ first diagonal bifurcation. Mechanical aspiration was performed and a small piece of debris was retrieved. We believe it was a broken-off fragment of the femoral artery that migrated on the tip of the TAVR delivery system. This i...

Spontaneous Coronary Artery Dissection Post Partum
J Invasive Cardiol. 2021 Apr;33(4):E316.ABSTRACTA previously healthy 30-year-old woman presented with intensive anterior myocardial infarction at day 6 post partum. Coronary angiogram demonstrated a proximal left anterior descending coronary artery dissection with an intimal flap starting at the ostial segment and extending to the mid segment separating a large false lumen from a narrow true lumen. Percutaneous coronary intervention was successfully performed using a drug-eluting stent with good angiographic result. Optical coherence tomography showed a widely patent vessel with a crescent hypointense image spanning the st...

Microbubbles Mimicking Prosthetic Mitral Valve Thrombosis
J Invasive Cardiol. 2021 Apr;33(4):E317.ABSTRACTA 36-year-old woman with a history of redo mitral valve replacement (bileaflet mechanical mitral valve prosthesis) in 2002 for prosthetic mitral valve endocarditis presented to the emergency department with a history of recurrent palpitations. A transthoracic echocardiogram was performed and falsely indicated a diagnosis of prosthetic mitral valve thrombosis. However, review of the echocardiogram by an experienced echocardiologist revised the diagnosis to microbubbles formation phenomenon with mechanical mitral prosthesis. Frame-by-frame analysis or reducing the frame rate of...

Acute Treatment and 5-Year Follow-up of Longitudinal Deformation of a Bioresorbable Scaffold
J Invasive Cardiol. 2021 Apr;33(4):E318-E319.ABSTRACTA 46-year-old man with type 1 diabetes underwent percutaneous coronary intervention with bioresorbable scaffold implantation for a long segment of physiologically significant left anterior descending coronary artery disease. The procedure was complicated by longitudinal stent deformation (LSD). The images carry several important educational messages for clinicians. First, as with all stents, LSD is possible in extreme circumstances. Second, as the device is not seen angiographically, it is imperative that optical coherence tomography be performed to confirm LSD. When rec...

Mitral Valve Surgery After Failed MitraClip: A Single-Center Experience
CONCLUSION: When performed by an experienced mitral surgeon and within 1 year of failed MitraClip implantation, surgical MV repair is feasible in most patients who were surgical repair candidates before the clip. Having the option for surgical MV repair after failed MitraClip is important to preserve optimal long-term outcomes for patients who undergo transcatheter mitral repair with MitraClip, especially as ongoing trials are shifting to study lower-risk patients who are also candidates for surgical repair.PMID:33794477 (Source: The Journal of Invasive Cardiology)

Evaluation of a Real-World In-Hospital Antiplatelet-Switching Strategy Following Coronary Interventions: The SWITCH Study
CONCLUSIONS: A strategy of using newer, fast-acting, and reliable antiplatelet agents prior to PCI and acutely switching to long-term clopidogrel therapy appears safe and efficacious. Although the superiority of the newer antiplatelet agents for long-term post-PCI dual-antiplatelet therapy in a trial setting is well established, the impact of increased adherence to lower-cost clopidogrel therapy in the real-world setting merits further consideration.PMID:33794478 (Source: The Journal of Invasive Cardiology)

Perforation of an Aortopulmonary Collateral: A Scary Sight in the Lab!
J Invasive Cardiol. 2021 Apr;33(4):E312-E313.ABSTRACTA 12-year-old boy with complex cyanotic congenital heart disease with single-ventricle physiology was planned for univentricular repair. Aortopulmonary collateral occlusion using thrombotic embolization coils was planned, but during the procedure, there was perforation of an aortopulmonary collateral arising from the descending thoracic aorta. The teaching point from this case is that all aortopulmonary collaterals do not necessarily need to be occluded; when occlusion is performed, coils must be appropriately sized.PMID:33794479 (Source: The Journal of Invasive Cardiology)

The Yin-Yang Sign of Severe Mitral Regurgitation
J Invasive Cardiol. 2021 Apr;33(4):E314.ABSTRACTIn select patients with severe, eccentric mitral regurgitation, we have observed that the regurgitant jet may entrain blood along the left atrial wall to produce a Chinese yin-yang symbol on color Doppler. This clinical imaging series demonstrates this unique phenomenon in an 81-year-old woman with symptomatic, severe, functional mitral regurgitation secondary to non-ischemic cardiomyopathy who was referred for transcatheter mitral valve repair. The yin-yang symbol resolved on transthoracic echocardiography after placement of 2 MitraClip NTR devices.PMID:33794480 (Source: The...
