Background: Cancer patients with heart failure (HF) and severe mitral regurgitation (MR) are often considered to be at risk for surgical mitral valve repair/replacement. Severe MR inducing symptomatic HF may prevent delivery of potentially cardiotoxic chemotherapy and complicate fluid management with other cancer treatments.

Objectives: To evaluate the outcome of percutaneous mitral valve repair (PMVR) in oncology patients with HF and significant MR.

Methods: Our study comprised 145 patients who underwent PMVR, MitraClip, at Hadassah Medical Center between August 2015 and September 2019, including 28 patients who had active or history of cancer. Data from 28 cancer patients were compared to 117 no-cancer patients from the cohort.

Results: There was no significant difference in the mean age of cancer patients and no-cancer patients (76 vs. 80 years, P = 0.16); 67% of the patients had secondary (functional) MR. Among cancer patients, 21 had solid tumor and 7 had hematologic malignancies. Nine patients (32%) had active malignancy at the time of PMVR. The mean short-term risk score of the patients was similar in the two groups, as were both 30-day and 1-year mortality rates (7% vs. 4%, P = 0.52) and (29% vs. 16%, P = 0.13), respectively.

Conclusion: PMVR in cancer patients is associated with similar 30-day and 1-year survival rate compared with patients without cancer. PMVR should be considered for cancer patients presenting with HF and severe MR and despite their malignancy. This approach may allow cancer patients to safely receive planned oncological treatment

Background: The prevalence of aortic stenosis increases with advancing age. Once symptoms occur the prognosis in patients with severe aortic stenosis is poor. The current and recommended treatment of choice for these patients is surgical aortic valve replacement. However, many patients, mainly the very elderly and those with major comorbidities, are considered to be at high surgical risk and are therefore denied treatment. Recently, a transcatheter alternative to surgical AVR[1] has emerged.

Objectives: To describe the first year experience and 30 day outcome of transcatheter aortic self-expandable CoreValve implantation in Israel.

Methods: Transcatheter aortic valve implantation using the CoreValve system has been performed in Israel since September 2008. In the following year 55 patients underwent CoreValve TAVI[2] in four Israeli centers.

Results: Patients' mean age was 81.7 ± 7.1 years; there were 35 females and 20 males. The mean valve area by echocardiogram was 0.63 ± 0.16 cm². The calculated mean logistic Euroscore was 19.3 ± 8%. Following TAVI, mean transvalvular gradient decreased from baseline levels of 51 ± 13 to 9 ± 3 mmHg. The rate of procedural success was 98%. One patient died on the first day post-procedure (1.8%) and all-cause 30 day mortality was 5.5% (3 of 55 patients). One patient had a significant post-procedural aortic regurgitation of > grade 2. Symptomatic improvement was evident in most patients, with reduction in functional capacity grade from 3.2 ± 0.6 at baseline to 1.4 ± 0.7. The most common post-procedural complication was complete heart block, which necessitated permanent pacemaker implantation in 37% of patients.

Conclusions: The Israeli first year experience of transcatheter aortic valve implantation using the CoreValve self-expandable system demonstrates an effective and safe procedure for the treatment of severe aortic stenosis in patients at high surgical risk.

Background: Infective endocarditis is a common disease with significant morbidity and mortality.

Objectives: To define clinical and echocardiographic parameters predicting morbidity and in-hospital mortality in patients with infective endocarditis hospitalized in a tertiary hospital from 1991 to 2000.

Methods: All patients with definite IE diagnosed according to the Duke criteria were included. We examined relevant clinical features that might influence outcome.

Results: The study group comprised 100 consecutive patients, 77 with native valve and 23 with prosthetic valve endocarditis. The overall in-hospital mortality rate was 8%. There was a higher mortality in the PVE[1] group compared to the NVE[2] group (13% vs. 7%, P = 0.07). The mortality rate in each group, with or without surgery, was not significantly different. Clinical predictors of mortality were older age and hospital-acquired endocarditis. The presence of vegetations and their size were significant predictors of major embolic events and mortality. Staphylococcus aureus was a predictor of mortality (25% vs. 5%, P < 0.005) and abscess formation. Multivariate logistic analysis identified vegetation size and S. aureus as independent predictors of mortality.

Conclusions: Mortality is higher in older hospitalized patients. S. aureus is associated with a poor outcome. Vegetation size is an independent predictor of embolic events and of a higher mortality.
