Bacterial Infective Endocarditis Associated with Gerbode Ventricular Septal Defect: A Case Report.

A 61-year-old male presented to emergency department with symptoms of shortness of breath, palpitations, and night sweats. We performed bedside transthoracic echocardiography which showed shunt from the left ventricle to the right atrium in systole with color Doppler examination. Gerbode-type ventricular septal defect and an image of a fibrillar, mobile mass compatible with vegetation was observed just above the tricuspid valve. We performed transesophageal echocardiography which showed vegetations on the aortic valve noncoronary cusp. Two sets of blood cultures were positive for Streptococcus sanguinis. The patient was evaluated by the heart team and an operation decision was made for the patient. The patient underwent surgery after 2 weeks of antibiotic theraphy. In the surgery, the Gerbode-type ventricular septal defect was closed with a polytetrafluoroethylene patch. Tricuspid annuloplasty was performed with De Vega technique. Mechanical aortic valve was implanted. Postoperative transthoracic echocardiography showed no residual shunt.

Long-term follow-up of patients with drug-related atrioventricular block without a need of permanent pacemaker during index hospitalization.

BACKGROUND: Most of the patients hospitalized due to drug-related atrioventricular (AV) block do not require permanent pacemaker implantation (PPI) since AV block regresses following cessation of the responsible drug. However, AV block requiring PPI may relapse in long-term follow-up. In this study, we retrospectively evaluated the factors predicting the need for a PPI in the long-term follow-up in patients admitted to our hospital with drug-related AV block but did not require PPI in index hospitalization. RESULTS: We evaluated 177 patients who had been hospitalized with drug-related AV block between January 2012 and July 2020 and who had not required PPI during hospital follow-up. The patients were divided into two groups according to whether PPI was performed or not. The independent predictors of long-term PPI were evaluated and the effect of glomerular filtration rate (GFR) of the patients during the index hospitalization on the long-term outcome was compared. A GFR above 60 ml/min is an independent significant risk factor in predicting long-term permanent pacemaker implantation in drug-related AV blocks. It is found that the need for PPI was 2.64 times higher without adjusted and 1.9 times higher with adjusted for all covariates in patients with GFR above 60 ml/min during hospitalization compared to those with GFR below 30 ml/min. CONCLUSIONS: GFR may be considered as an indicator of the PPI need in patients with drug-related atrioventricular AV block.
