Ruptured Sinus of Valsalva Aneurysm in a Patient with a Ventricular Septal Defect Who Dropped Out of Lifelong Medical Follow-up.

Ruptured sinus of Valsalva aneurysm (RSOVA) is a rare cardiac condition associated with high morbidity and mortality rates. We herein report a 35-year-old man with a history of ventricular septal defect (VSD). He had a history of interrupted hospital visits and presented to the emergency department with dyspnea, palpitations, and dizziness for a few days. Auscultation detected a continuous murmur. Transthoracic echocardiography followed by transesophageal echocardiography demonstrated RSOVA in the right ventricle with an aorto-right ventricular fistula. The fistula was resected, and the aneurysm was surgically repaired. The patient made a good recovery.

Purulent pericarditis-induced intracardiac perforation and infective endocarditis due to Parvimonas micra: a case report.

BACKGROUND: Purulent pericarditis, a rare disease with a high associated mortality rate in patients without adequate treatment, can cause serious complications, such as perforation of the surrounding tissue and organs. Parvimonas micra is a very rare cause of purulent pericarditis. CASE SUMMARY: A 70-year-old male patient presented to our emergency room with chest pain of 10 days' duration. An electrocardiogram showed ST-segment elevation and PR-segment depression on multiple leads. A transthoracic echocardiogram showed normal left ventricular function and a large amount of pericardial effusion. Acute pericarditis was diagnosed, and anti-inflammatory drug therapy was initiated. Due to the lack of improvement in the symptoms, pericardiocentesis was performed on Day 8 and revealed about 800 cc of the bloody fluid. Parvimonas micra was detected in a culture of the pericardial effusion and blood. Although intravenous antibiotic therapy was initiated for purulent pericarditis, his fever persisted. Computed tomography of the chest performed on Day 14 showed an abscess cavity in the pericardial space around the right atrium (RA). Furthermore, transoesophageal echocardiography revealed vegetation in the RA. Emergency surgery confirmed the presence of vegetation and minor perforation of the RA with communication to the abscess cavity. After surgical therapy, the patient clinically improved and was discharged on Day 51. DISCUSSION: In cases of acute pericarditis, purulent pericarditis should be considered if clinical improvement is not observed after initial treatment with anti-inflammatory drugs. Once the diagnosis of purulent pericarditis is made, aggressive source control is necessary for improved clinical outcomes.

Safety and Efficacy of Simultaneous Inoculations of Pneumococcal and Influenza Vaccines in Patients with Coronary Artery Disease.

AIM: Pneumococcal and influenza infections can cause serious morbidity and mortality in patients with cardiovascular diseases. The purpose of this study was to investigate the safety and efficacy of simultaneous inoculations of 23-valent pneumococcal polysaccharide vaccine (PPSV23) and trivalent influenza vaccine (TIV) in patients with coronary artery disease (CAD). METHODS: This was a prospective, randomized, single-blind, placebo-controlled study. A total of 40 patients with CAD were randomly assigned to the TIV＋PPSV23 (simultaneous inoculations of TIV and PPSV23) and TIV＋Placebo (inoculations of TIV and placebo) groups. Primary outcomes were the safety of simultaneous vaccinations and the changing of circulating cardiovascular biomarkers before, at 4-, and at 12-weeks after vaccinations. RESULTS: The baseline characteristics between the two groups were identical. The prevalence of injection-site pain, swelling, and reddening were 47%, 37%, and 37% in the TIV＋PPSV23 group, and 10%, 5%, and 0% in the TIV＋Placebo group, respectively. All reactions were self-limited. Body temperature ＞37.0℃ or serious injection-related reaction was not observed. The levels of white blood cells, high-sensitivity C-reactive protein, N-terminal pro-B-type natriuretic peptide, pentraxin-3, and malondialdehide-modified low-density lipoprotein (LDL), were not significantly different between the two groups before and after vaccinations. The levels of anti-oxidized LDL were significantly and step-wisely decreased from baseline, to 4-, and 12-weeks vaccinations in the both groups. No significant changes of other markers were observed in both groups at each time point. CONCLUSION: Simultaneous inoculations of TIV and PPSV23 were safety in patients with CAD, suggesting that dual vaccinations can be considered even in patients with CAD.

Ischemic Cardiomyopathy with a Rapid Progression from Thrombotic Thrombocytopenic Purpura.

An 83-year-old woman who complained of dizziness and nausea visited our hospital. An electrocardiogram showed ST-segment elevation in multiple leads and an echocardiogram showed severe hypokinesis of the anteroseptal wall of the left ventricle. However, emergency coronary angiography showed no stenotic lesions in any coronary arteries. A laboratory examination showed thrombocytopenia, renal dysfunction, and hemolysis. We therefore diagnosed the patient with thrombotic thrombocytopenic purpura (TTP). While we were preparing to initiate plasma exchange therapy, she suddenly developed cardiopulmonary arrest. A postmortem examination revealed microthrombi in the small vessels of the myocardium. We herein report a case of ischemic cardiomyopathy with a rapid progression from TTP.

New Bisabolane-Type Sesquiterpenes from the Aerial Parts of Lippia dulcis.

Two new bisabolane-type sesquiterpenes, lippidulcine A (3) and epilippidulcine A (4), have been isolated from the aerial parts of Lippia dulcis TREV. along with five known flavonoids, cirsimaritin (5), salvigenin (6), eupatorin (7), 5-hydroxy-6,7,3',4'-tetramethoxyflavone (8) and 5,3'-dihydroxy-6,7,4',5'-tetramethoxyflavone (9), three known phenylethanoid glycosides, decaffeoylverbascoside (10), acteoside (11) and isoacteoside (12), and two known iridoid glucosides, 8-epiloganin (13) and lamiide (14). Their chemical structures have been determined on the basis of spectroscopic data. Among them, 5, 7, and 9 exhibited almost the same activity as that of alpha-tocopherol, and 10-12 were identified as stronger antioxidants than alpha-tocopherol using the ferric thiocyanate method.
