A 73-year-old man with history significant for paroxysmal atrial fibrillation on apixaban underwent percutaneous coronary intervention (PCI) of the left anterior descending artery via transradial access. The patient was discharged on clopidogrel, atorvastatin, carvedilol, isosorbide mononitrate, losartan, and apixaban.

Guidelines promote the use of distal embolic protection devices (EPD) to protect the distal arterial bed during SVG PCI. However, this approach has shown less-than-optimal results in many studies.

We report a case of recurrent ST-segment elevation myocardial infarction (STEMI) due to a previously implanted under-expanded stent with in-stent thrombosis refractory to traditional interventional techniques. We underscore the utility of bail-out shockwave intravascular lithotripsy to tackle previously under-expanded stents in this acute setting.

Only transfemoral access has been shown to have better clinical outcomes than surgical aortic valve replacement. In our patient, severe calcification of the distal abdominal aorta posed difficulty in using transfemoral access for TAVR.

Primary TR is caused by a congenital or acquired abnormality of the tricuspid valve apparatus (leaflets, chordae, papillary muscles, or annulus). Secondary TR is due to insufficient coaptation from dilation of tricuspid valve annulus due to the right ventricle (RV) or right atrium (RA) remodeling and increased RV pressures.

While they play an important role in providing nourishment to the myocardium by maintaining adequate perfusion, they are also responsible for a physiologic right to left shunt in the body's circulation. We present a case report of this rare anatomic finding of extensive Thebesian veins causing acute coronary syndrome and Takostubo cardiomyopathy.

Case Summary: We present a case of 67-year-old man with severely symptomatic post-thrombotic syndrome (PTS) with persistent high-grade femoral DVT despite prior compressive therapy and chronic oral anticoagulation.
High calcification of coronary artery plaque is a frequent cause of suboptimal stent expansion, which can result in stent thrombosis and restenosis. Shockwave intravascular lithotripsy (S-IVL) represents a new frontier in the treatment of highly calcified coronary lesions. It can be an excellent alternative to intracoronary atherectomy in extremely high-risk lesions.

Case Summary: We present successful treatment of a 52-year-old old man presenting with AMICS following cardiac arrest and prolonged CPR via a Bipella approach for biventricular support and restoration of haemodynamic stability.
Discussion: This case demonstrates the importance of understanding the role of MCS in the management of cardiogenic shock; the value of the cardiac power output and pulmonary artery pulsatility index as haemodynamic metrics to assess the cardiac function of a patient with cardiogenic shock; and the importance of a Bipella MCS approach in high inpatient morbidity and mortality AMICS with biventricular failure.
Superior vena cava syndrome (SVCS) is traditionally associated with malignancy. However, approximately one-third of SVCS cases are due to intravascular devices and pacemakers. No specific guidelines exist for managing catheter-associated SVCS.

Methods: We used Nationwide Inpatient Sample (NIS) data to extract data for patients who were hospitalized with a primary/secondary diagnosis of TAVR as specified by International Classification of Disease (ICD-9) codes 35.05 and 35.
May-Thurner syndrome is an underrecognized anatomical variant that can lead to increased propensity for venous thrombosis in the lower extremities. We present a case of a 67-year-old female who presented with transient ischemic attack. Initial workup including CT scan of the head, MRI scan of the head, and magnetic resonance angiogram of the head and neck was unremarkable.

Methods: This study used the data from Nationwide Inpatient Sample database for the years 2002- 2012 to identify patients with vena caval filter placement.
