Coronary Artery Obstruction After Transcatheter Aortic Valve Implantation: Past, Present, and Future.

Coronary obstruction (CO) is a rare but critical complication of transcatheter aortic valve implantation. It is associated with significant morbidity and mortality. This comprehensive review elucidates the evolving landscape of CO risk assessment and management strategies in the contemporary era of transcatheter aortic valve implantation.

The Current State of Coronary Revascularization: Percutaneous Coronary Intervention versus Coronary Artery Bypass Graft Surgery.

The question of percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) surgery remains among the most important questions in the treatment of coronary artery disease. The leading North American and European societies largely agree on the current guidelines for the revascularization of unprotected left-main disease (ULMD) and multivessel disease (MVD) which are largely supported by the outcomes of several large randomized trials including SYNTAX, PRECOMBAT, NOBLE, and EXCEL. While these trials are of the highest quality, currently available, they suffer several limitations, including the use of bare metal and/or first-generation drug-eluting stents in early trials and lack of updated surgical outcomes data.

Early Mitral Valve Repair Failure in the Setting of Endocarditis: When to Reoperate?

Surgery is recommended for endocarditis complicated by annular abscess or destruction of the native valve. Guidelines also recommend valvular repair over replacement for endocarditis when feasible. Guidance on management of early repair failure is not well described.

Multimodality Imaging Involving Magnetic Resonance Facilitates Giant Symptomatic Myxoma Resection.

Myxoma, the most common adult primary cardiac tumor, can manifest with profound symptoms. The preferred treatment of symptomatic myxoma is surgical resection, which can be curative. Preoperatively, multimodality imaging provides crucial information on the number, size, location, and proximity of myxoma or myxomas to adjacent structures, thereby facilitating an optimal operative approach.

A Case of an Epithelioid Hemangioendothelioma Arising from the Innominate Vein Mimicking Cervical Metastatic Lymphadenopathy.

Epithelioid hemangioendothelioma (EHE) is a rare tumor usually presenting in soft tissue. EHE is a vascular malignancy of intermediate clinical behavior, with a histologic appearance of endothelial cells growing in nests or cords. Although EHE often originates from a vessel, it is relatively rare for a primary vascular EHE to originate from a large vein or artery.
