Objectives: To investigate current smoking trends among Israeli physicians.

Methods: All practicing physicians at a tertiary university-affiliated medical center in central Israel were invited to complete a Web-based questionnaire on smoking habits and smoking-related issues via the institutional email. Findings were compared to those in the general population and between subgroups.

Results: Of the 90 responders (53 male, 88 Jewish), 54 (60%) had never smoked, 21 (23.3%) were past smokers, and 15 (16.7%) were current smokers. The rate of current smokers was lower than in the general population. The proportion of current smokers was higher among residents than attending physicians and among physicians in surgical compared to medical specialties. Past smokers accounted for 17.9% of the residents (average age at quitting 26.2 years) and 28.1% of the attending physicians (average age at quitting 33.0 years). Non-smokers more frequently supported harsh anti-smoking legislation.

Conclusions: The rate of smoking is lower in physicians than in the general population but has not changed over the last 15 years. Anti-smoking programs should particularly target physicians in surgical specialties. 

Background: During the last decade new surgical techniques for mitral valve repair were developed. We have been using those techniques in order to widen the spectrum of patients eligible for MV[1] repair.

Objectives: To assess the operative and mid-term results a wide variety of surgical techniques.

Methods: From January 2004 through December 2006, 213 patients underwent MV repair in our institution. Valve pathology was degenerative in 123 patients (58%), ischemic in 37 (17%), showed annular dilatation in 25 (12%), endocarditis in 16 (8%), was rheumatic in 13 (6%), and due to other causes in 14 (7%). Preoperative New York Heart Association score was 2.35 ± 0.85 and ejection fraction 53 ± 12%. Isolated MV repair was performed in 90 patients (42%) and 158 concomitant procedures were done in 123 patients (58%). A wide variety of surgical techniques was used in order to increase the number of repairs compared to valve replacement.

Results: There were 7 in-hospital deaths (3.3%). NYHA[2] class improved from 2.19 ± 0.85 to 1.4 ± 0.6, and freedom from reoperation was 100%. Echocardiography follow-up of patients with degenerative MV revealed that 93% of the patients (115/123) were free of mitral regurgitation greater than 2+ grade. In patients operated by a minimal invasive approach there were no conversions to sternotomy, no late deaths, none required reoperation, and 96% were free of MR[3] greater than 2+ grade. The use of multiple surgical techniques enabled the repair of more than 80% of pure MR cases.

Conclusions: MV repair provides good perioperative and mid-term results, and supports the preference for MV repair over replacement, when feasible. Multiple valve repair techniques tailored to different pathologies increases the feasibility of mitral repair.

Background: Reports from Europe and North America indicate that significant changes have occurred in the practice of cardiac surgery in the last two decades.

Objectives: To examine the trends and case-mix in cardiac surgery in Israel and their relationship with changes in invasive cardiology.

Methods: We analysed data collected by the Ministry of Health from all cardiac centers in Israel from 1985 to 2002.

Results: Three periods were identified: the 1980s, when a relatively small number of operations were performed; 1990–1994, characterized by a dramatic rise in the number of operations; and 1994–present, characterized by a small decline and stabilization in the rate of operations. The percentage of valve procedures increased significantly from 15% of all cardiac surgeries in 1991 to 21% in 2002 (P = 0.002). In addition, the chance of a diagnostic coronary angiography being followed, in the same patient, by an interventional procedure such as percutaneous transluminal coronary angioplasty or by a coronary artery bypass graft increased dramatically from 42% in 1991 to 69% in 2002. At Rabin Medical Center, there was a constant decline in the percent of repeated CABGs[1] out of the total CABGs performed, from 6.7% in 1996 to 1.3% in 2002.

Conclusions: Despite the rise in the rate of percutaneous coronary interventions since 1991, there has been no significant decline in the rate of CABGs performed. However, there is a significant shift to more complex operations. The number of repeated CABG operations has significantly decreased and, in view of the growing use of arterial grafts and further improvements in invasive cardiology techniques, we expect this decline to continue.

Background:  After the introduction of endoscopic techniques to other surgical fields, like general surgery, gynecology and thoracic surgery, cardiac surgeons sought their own methods of using minimally invasive techniques.

Objectives:  To examine whether this approach is less invasive and yields better results, more desirable cosmetic results, and a more rapid and complete rehabilitation, maintaining safety, efficacy, and outcome equivalent to those of more established procedures, such as median sternotomy.

Methods:  From January 2000 to July 2001, 22 patients underwent video-assisted port-access mitral or aortic valve repair or replacement with the Heartport system in our department, and one underwent closure of atrial septal defect.

Results:  Intraoperative transesophageal echocardiography revealed excellent functional results. Total operating room time, perfusion time, and cross-clamp time in this technique decreased with our growing experience, and remains stable. There were no intraoperative reversals to mid-steronomy, no mortalities, and only one complication 24 hours after surgery.

Conclusions:  Thoracoscopic assisted cardiac surgery (via port access) provides all the advantages of minimally invasive surgery, accelerates recovery, decreases pain, and maintains overall surgical efficacy, while avoiding the complications and pathology of mid-sternotomy.  For appropriate patients, this is the method of choice in our department.
