[Resection of a Myxoma Orginating from the Coumadin Ridge with Superior Transseptal Approach:Report of a Case].

A 70-year-old man with a history of lacunar stroke about a year before was incidentally found to have primary cardiac tumor during the work up for orthopedic surgery. It uniquely originated from the coumadin ridge between the left upper pulmonary vein and the left atrial appendage. He underwent tumor resection under cardiopulmonary bypass with superior transseptal approach.

An Unusual Case of Bioprosthetic Mitral Valve Failure.

We report a case of sudden-onset pulmonary edema due to failure of a bioprosthetic mitral valve. Gross inspection revealed a leaflet tear at a stent post without calcification or pannus formation and no evidence of sutures. This case highlights the mechanical failure of a bioprosthetic mitral valve associated with missing sutures.

[Early Clinical Outcomes of Robotic Mitral Valve Repair;Initial Twenty Cases].

We report the early results of our initial 20 consecutive robotic-assisted mitral valve repairs at our institution. A total of 20 patients (aged 55±10 years, 15 males) underwent robotic assisted mitral repairs by using da Vinci system. Successful mitral valve repairs were done in all cases.

Usefulness of F-fluorodeoxyglucose positron emission tomography/computed tomography angiography in a patient with blood culture-negative prosthetic valve endocarditis complicated with perivalvular abscess: a case report.

Background: Prosthetic valve endocarditis (PVE) is a life-threatening systemic infection involving a high mortality rate and severe complications, including perivalvular abscess. Early diagnosis and detection of PVE continue to be challenging in clinical settings.

Case Summary: A 64-year-old man with a history of mechanical aortic valve implantation 12 years prior was referred to our hospital with a major complaint of high fever and was admitted.

[Surgical Treatment of Acute Infective Endocarditis after Transcatheter Aortic Valve Replacement].

Infective endocarditis (IE) after transcatheter aortic valve replacement (TAVR) is a rare complication, but has a high mortality. An 86-year-old female with symptomatic severe aortic stenosis underwent TAVR at our hospital and she was discharged without complication after 10 days. She was readmitted with high fever and acute heart failure 1 month later.
