Clinical significance of corrected relative flow reserve derived from N-ammonia positron emission tomography combined with coronary computed tomography angiography.

Background: This study evaluated corrected relative flow reserve (RFR) derived from N-ammonia positron emission tomography (PET) combined with coronary computed tomography angiography (CTA).

Methods: We analyzed 61 patients who underwent coronary CTA, N-ammonia PET, and invasive coronary angiography. Triple-vessel disease were excluded.

A unique case of ST-elevation myocardial infarction related to very late stent thrombosis.

A 67-year-old man was transferred to our hospital because of anterior ST elevation myocardial infarction (STEMI). He had a history of a sirolimus-eluting stent implantation from the left main to the left anterior descending coronary artery (LAD) 9 years before and had undergone laparoscopic prostatectomy 8 days before in the setting of discontinuation of dual antiplatelet therapy. Emergent coronary angiography showed total occlusion in the distal LAD that was successfully treated by aspiration alone.

Beneficial effects of adaptive servo-ventilation therapy on readmission and medical costs in patients with chronic heart failure.

Adaptive servo-ventilation (ASV) therapy is a novel modality of noninvasive positive pressure ventilation and is now widely utilized to treat patients with chronic heart failure (CHF). However, there has been no clinical study of the effect of ASV therapy on readmission and cost-effectiveness for the treatment of CHF. The present study was conducted to evaluate the clinical efficacy and cost-effectiveness of home ASV therapy in 45 patients with a history of two or more admissions a year for worsening CHF.

Isolated Left Atrial Infective Mural Endocarditis.

A 52-year-old man presented with a fever and malaise. Transthoracic echocardiogram was performed because of a holosystolic murmur, which showed mitral valve prolapse and a regurgitation jet toward the posterior wall of the left atrium. There was no apparent vegetation at any valves.
