We report an extremely rare case of spontaneous closure of grade 1 coronary perforation by the snowplow phenomenon during the revascularization of a subtotal occlusion in the left anterior descending coronary artery. Coronary artery perforation is usually a nightmare during coronary intervention in the cardiac catheterization laboratory. While large coronary perforation requires the deployment of a covered stent, small perforations require heparin reversal, prolonged balloon inflation, deployment of small coils, or gel foam closure. The coronary segment with a small perforation was stented with a drug-eluting stent (DES), which might have resulted in the shifting of the fatty plaque toward the perforation and subsequently sealing the coronary perforation.

Surgical Bailout in Patients Undergoing Transfemoral Transcatheter Aortic Valve Replacement: Incidence, Trends, and Clinical Outcomes.

Background: Transcatheter aortic valve replacement (TAVR) harbors the risk of periprocedural complications that require emergent cardiac surgery, or "surgical bailout." Surgical bailout intends to be lifesaving but is associated with high mortality. This has given rise to discussion on the necessity of surgical backup during TAVR.

Coronary artery calcification is an impediment to percutaneous coronary interventions by obstructing the device pathway or stent deployment. To facilitate percutaneous coronary intervention in such complex lesions, high-pressure balloon dilations, atherectomy procedures, and specialty balloons are used but they all come with considerable limitations and periprocedural complications like dissection and perforation. To surpass these disadvantages, intravascular lithotripsy was introduced which acts by delivering high-pressure pulsatile sonic waves circumferentially thereby destroying the calcium deposits.

Background: Transvenous pacemakers (TVP) and leadless pacemakers (LP) are two reliable permanent modalities for the treatment of heart rhythm disorders. Several observational studies explored the safety and efficacy of the two devices. The aim of this meta-analysis study is to present a comparative analysis of the safety of leadless versus transvenous pacemakers.

Introduction: The super high-pressure NC balloon (OPN NC; SIS Medical AG, Winterthur, Switzerland) is increasingly used in percutaneous coronary intervention (PCI). We performed a systematic review and meta-analysis of its efficacy and safety.
Methods: A systematic review was conducted using PubMed and the Cochrane Library to identify studies using the OPN NC balloon in PCI.

Perforation of the duodenum after trauma has a low incidence and its coincidence with BTAI is very rare. The clinical condition of the patient is very important for deciding the treatment priority. In this patient, considering the stable condition and degree of aorta injury, we chose TEVAR before laparotomy.
