Drospirenone-containing oral contraceptives and risk of adverse outcomes after myocardial infarction.

The association between oral contraceptives (OC) and myocardial infarction remains controversial. The new generation contraceptive Yasmin (30 µg ethinyl estradiol and 3 mg drospirenone) has a lower estrogen and newer progestin component. To date, there are no data available for the myocardial infarction risk and outcome for drospirenone. We aimed to investigate the effect of Yasmin use on cardiovascular outcomes in patients with acute ST segment elevation myocardial infarction (STEMI) undergoing primary angioplasty.

In-hospital prognostic value of admission plasma B-type natriuretic peptide levels in patients undergoing primary angioplasty for acute ST-elevation myocardial infarction.

OBJECTIVES We assessed in-hospital prognostic value of admission plasma B-type natriuretic peptide (BNP) levels in patients undergoing primary percutaneous coronary intervention (p-PCI) for acute ST-elevation myocardial infarction (STEMI). STUDY DESIGN In a retrospective design, we evaluated 992 patients (801 males, 191 females; mean age 56 ± 12 years) treated with p-PCI for STEMI. The patients were divided into two groups according to the admission BNP levels, taking the cut-off value of BNP as 100 pg/ml; i.e, ≥ 100 pg/ml (n=334, 33.7%) and <100 pg/ml (n=658, 66.3%). Postprocedural angiographic and clinical in-hospital results were recorded. RESULTS No-reflow (24% vs. 9%), heart failure (32.3% vs. 5.5%) and death (15.6% vs. 1.7%) were significantly more common in patients with BNP ≥ 100 pg/ml (p<0.001). In multivariate analysis, elevated baseline BNP level was identified as an independent predictor of no-reflow (OR=1.83; 95% CI 1.22-2.74, p=0.003), acute heart failure (OR=2.67; 95% CI 1.55-4.58, p<0.001), and in-hospital mortality (OR=3.28; 95% CI 1.51-7.14, p=0.003). In receiver operating characteristic curve analysis, the area under the curve and sensitivity/specificity of the cut-off value of BNP (100 pg/ml) for prediction of clinical endpoints were 0.741 and 58.6%/70.3% for no-reflow, 0.822 and 75%/73.3% for heart failure, and 0.833 and 82.5%/69.4% for death, respectively (p<0.001 for all). CONCLUSION Elevated admission BNP level is an independent predictor of angiographic no-reflow, acute heart failure, and mortality in STEMI patients during in-hospital period, suggesting that it might be incorporated into traditional risk scoring systems to improve early risk stratification.

Mitral valve with a single leaflet

Congenital anomalies of the mitral valve apparatus are rare. Of such cases, congenital mitral stenosis, atresia, accessory valvular tissue, and cleft mitral valve are more common. Descriptions of unileaflet mitral valves (either partial or complete leaflet agenesis/hypoplasia) are extremely rare and largely limited to a few case reports. We report herein a 45-year-old nulliparous woman presenting to our outpatient clinic with chest discomfort and dyspnea on minimal exertion. Mitral valve with a single leaflet leading to a significant obstruction in left ventricular outflow was seen on transthoracic echocardiography and confirmed with transesophageal two- (2D) and three-dimensional (3D) echocardiography. Metoprolol was prescribed to relieve obstruction and symptoms.

Double-orifice mitral valve associated with bicuspid aortic valve: a rare case of incomplete form of Shone's complex

Double-orifice mitral valve (DOMV) is a rare congenital malformation characterized by two separate valve orifices of varying sizes in association with the abnormalities of the subvalvular apparatus. It has been reported to be associated with a variety of other congenital malformations. We report a rare case of incomplete form of Shones complex composed of a complete bridge-type DOMV and bicuspid aortic valve, well demonstrated by both transthoracic and transoesophageal echocardiography and cardiac magnetic resonance imaging.

Relationship between angiotensin I-converting enzyme insertion/deletion gene polymorphism and retinal vein occlusion

To evaluate the association between angiotensin I-converting enzyme insertion/deletion (ACE I/D) gene polymorphism and retinal vein occlusion (RVO). A total of 80 patients with retinal vein occlusion who was admitted to the Eye Department of Kartal Training and Research Hospital between 2008 and 2011, and 80 subjects were enrolled in this retrospective case–control study. Patients who experienced RVO within one week to six months of study enrolment were included, and those with coronary artery diseases, prior myocardial infarction history and coagulation disturbances were excluded from the study. The diagnosis was made by ophthalmoscopic fundus examination and fluorescein angiography. The ACE gene I/D polymorphism was determined by polymerase chain reaction, and the ACE gene was classified into three types: I/I, I/D and D/D. In multivariate logistic regression analysis, ACE D/D genotype (p = 0.035), diabetes-mellitus (p = 0.019) and hypertension (p = 0.001) were found to be independent predictive factors for RVO. The results of the present study reveal that ACE D/D polymorphism is an independent predictive factor for RVO. However, one cannot definitely conclude that ACE gene polymorphism is a risk factor for retinal vein occlusion.

Acute ST-elevation myocardial infarction in early puerperium due to severe left main coronary stenosis in a woman with familial hyperlipidaemia : online article - case report

Acute myocardial infarction (AMI) is a rare but often catastrophic event during pregnancy, delivery or puerperium, leading to a high mortality rate. It has different pathogenic mechanisms, such as atherosclerosis, vasospasm, thrombosis and coronary dissection. Although MI has been reported in pregnant women at all stages of pregnancy and postpartum, it occurs more commonly in the third trimester and most commonly involves the anterior wall. Evidence suggests that pregnancy itself is an independent risk factor for MI, conferring a three- to four-fold higher risk than that of nonpregnant women matched for age, possibly due to the unique physiological changes required to meet the demands of a growing foetus. We report a case of a 27-year-old woman with familial hyperlipidaemia presenting with myocardial infarction six days after caesarean delivery, secondary to severe left main coronary stenosis (LMCA), who was treated with emergency coronary artery bypass grafting (CABG).

Acute aortic dissection with a dangerous duo in an adolescent boy.

Acute type II aortic dissection and aortic coarctation are rare combined disorders. This report is of a patient with coarctation, a bicuspid aortic valve and type II dissection, who underwent emergency repair for the dissection, with aortic valve preservation. Repair of the coarctation was planned for a future occasion. The optimal sequence and timing of the repair, the best surgical technique, adequacy of blood perfusion, and the most appropriate arterial cannulation site are important issues in the repair of aortic dissection secondary to aortic coarctation.

Intracardiac fistula in a patient with prosthetic valve endocarditis.

A 44-year-old female patient presented with fever, dyspnea, and pretibial edema 18 months after prosthetic aortic and mitral valve replacement. Transthoracic echocardiography (TTE) showed vegetations on the aortic and mitral valves and moderate paravalvular aortic regurgitation between the right and noncoronary cusps, but no abscess formation. A probable pannus formation was also noted around the prosthetic mitral valve, along with moderate mitral stenosis. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus, and antibiotherapy (vancomycin 30 mg/ kg/day and gentamicin 3 mg/kg/day) was started. On the third day of treatment, the patient developed pulmonary edema and bedside TTE revealed severe aortic regurgitation. Thus, emergency redo aortic and mitral valve replacement was performed. She was extubated on the first postoperative day, and her hemodynamic status was stable. Echocardiographic examination showed both prosthetic valves functioning normally. However, her clinical status deteriorated suddenly on the sixth postoperative day, resulting in cardiogenic shock. On TTE, a flow jet resembling Ahmet Güler Soe Moe Aung Ali Karagöz Cevat Kırma
