An isolated anterior mitral leaflet cleft: a case report.

INTRODUCTION: The anterior mitral leaflet cleft is an unusual congenital lesion most often encountered in association with other congenital heart defects. The isolated anterior leaflet cleft is quite a rare anomaly and is usually cause of mitral valve regurgitation. The importance of the lesion is that it is often correctable. When feasible, cleft suture and, eventually, annuloplasty are preferable to valve replacement. Echocardiography is the first choice technique in the evaluation of mitral valve disease, providing useful information about valve anatomy and hemodynamic parameters. CASE PRESENTATION: We present a case of an isolated anterior mitral leaflet cleft producing moderate-severe mitral regurgitation correctly identified by echocardiography and successfully surgically corrected. CONCLUSION: Isolated cleft is a rare aberration, that has to be known in order to be diagnosed. Transthoracic and transesophageal echocardiography is the most useful non invasive technique for cleft diagnosis and to indicate the right surgical correction.

Influence of cardiac-resynchronization therapy on heart rate and blood pressure variability: 1-year follow-up.

BACKGROUND: Several studies have shown that cardiac-resynchronization therapy (CRT) improves haemodynamic function, cardiac symptoms, and heart rate variability (HRV) and reduces the risk of mortality and sudden death in subjects with chronic heart failure (CHF). In subjects with CHF, power spectral values for the low-frequency (LF) component of RR variability < or =13 ms2, are associated with an increased risk of sudden death. AIMS AND METHODS: To assess whether spectral indexes obtained by power spectral analysis of HRV and systolic blood pressure (SBP) variability could predict malignant ventricular arrhythmias in patients with severe CHF treated with an implantable cardioverter-defibrillator (ICD) alone or with ICD+CRT. In addition, changes in non-invasive spectral indices using short-term power spectral analysis of HRV and SBP variability during controlled breathing in 15 patients with CHF treated with an ICD alone and 16 patients receiving ICD+CRT, were assessed pre-treatment and at 1 year. RESULTS: Arrhythmias necessitating an appropriate ICD shock were more frequent in subjects who had low LF power. CRT improved all spectral components, including LF power. CONCLUSIONS: Low LF power values predict an increased risk of malignant ventricular arrhythmias; after 1 year of CRT most non-spectral and spectral data, including LF power, improved. Whether these improvements lead to better long-term survival in patients with CHF remains unclear.

Long-term outcome of sirolimus-eluting vs bare-metal stent in the setting of acute myocardial infarction: 5-year results of the SESAMI trial.

BACKGROUND: few long-term randomized data on safety and effectiveness of sirolimus-eluting stent (SES) in the ST-segment elevation myocardial infarction (STEMI) setting are available. The aim of the present investigation was to evaluate the 5-year clinical outcome of SES vs bare-metal stent (BMS) implantation in patients with STEMI. METHODS: 320 STEMI patients were randomized to receive SES or BMS. The primary end-point was the incidence of target vessel failure (TVF) at 5-year follow-up. The secondary end-points were the rate of target lesion revascularization (TLR), major adverse cardiovascular events (MACE), death or non-fatal MI and stent thrombosis (ST). Event rates from 1 to 5 years in patients undergoing TLR and those TLR free at 1 year were also investigated. RESULTS: The 5-year survival rate free from TVF and TLR was significantly higher in the SES than in the BMS group (85% vs 76% p=0.038; 92% vs 85% p=0.045, respectively). The lower incidence of adverse events was achieved in the first year of follow-up. The cumulative incidence of MACE, death or non-fatal MI and ST was comparable in the 2 groups at 5-year follow-up. Moreover death or MI incidence was 5% in the patients who did not experience TLR within 1-year and 16% in those who experience TLR in the same period (p=0.033). Predictors of death or MI during 5-year follow-up were TLR within 1 year (OR 3.4, 95% CI 1.1-10.1; p=0.04) and small vessels treatment (OR 4.8 95% CI 1.7-13.0; p=0.002). CONCLUSIONS: The clinical benefits of SES are maintained up to 5years without safety concerns.

Gore Helex septal occluder for percutaneous closure of patent foramen ovale associated with atrial septal aneurysm: short- and mid-term clinical and echocardiographic outcomes.

OBJECTIVES: To evaluate the short- and mid-term clinical and echocardiographic outcome of HELEX Septal Occluder (HSO) implantation in patients with patent foramen ovale (PFO) and atrial septal aneurysm (ASA). BACKGROUND: Percutaneous closure of PFO and ASA with HSO device has not been systematically studied. METHODS: We studied 90 patients with PFO and ASA with documented paradoxical embolic events. The procedural and clinical results of 30 consecutive patients treated with HSO were compared with those obtained in 30 consecutive patients treated with the Amplatzer PFO (APO) and with those of a further 30 consecutive patients treated with the Amplatzer Cribriform (AMF). Primary endpoint was the persistence of moderate to severe residual right-to-left shunting (rRLS) at 6-month follow-up. The incidence of death or recurrent embolic events (REE) at 1-year follow-up were also investigated. RESULTS: The procedure was successfully completed in all patients. There was one HSO device embolization. Immediate moderate RLS was significantly higher in the HSO group compared to APO and AMF groups (20% vs 3% vs 0%, respectively; P=.008). The incidence of moderate rRLS decreased but was still significant at 6-month follow-up (17% in the HSO group vs 3% in the APO group; P=.02). At 1-year follow-up, moderate rRLS persisted only in the HSO group (7%). No deaths or REE were observed during hospitalization or at 1-year follow-up. CONCLUSION: HSO device seems to be a second-line device as compared to Amplatzer occluders for the treatment of PFO and ASA.

Translation and validation of the Italian version of the European Heart Failure Self-care Behaviour Scale.

BACKGROUND: Heart failure (HF) patients can benefit from management programmes that include education, discharge planning and structured follow-up. Therefore, it is important to evaluate the improvement of self-care as a result of these interventions. The European Heart Failure Self-care Behaviour Scale (EHFScBS) was developed as a reliable and valid instrument for self-care evaluation. OBJECTIVES: The aims were to translate and validate the Italian version of the EHFScBS and to evaluate factors related to self-care. METHODS: The translation and validation were performed as follows: translation and back-translation; evaluation by four bilingual cardiologists; administration to healthy individuals of different ages and education to test language comprehension; final correction by cardiologists experienced in cognitive assessment; and administration in HF patients to test validity and internal consistency. RESULTS: A sample of 93 HF patients (mean age 77 +/- 6 years, 53% women) was considered for the validation procedure. Fifty-four (58%) patients were already followed in the HF clinic (HFC), with previous HF education, and 39 (42%) were evaluated at baseline. The reliability analysis showed a Cronbach's alpha of 0.82. At multivariate analysis, age, not already followed in HFC and female sex were associated to worse self-care behaviour. When HFC patients were considered separately, an association between self-care and cognitive dysfunction was observed. CONCLUSION: The EHFScBS appears to be a valid and reliable instrument in the Italian version also. Self-care behaviour appears to depend on age and sex and a previous HF education. Mild to moderately impaired cognitive function seems to influence self-care in patients who have already received HF education.
