Meta Analysis
Should the mitral valve be repaired for moderate ischemic mitral regurgitation at the time of revascularization surgery?
Ischemic mitral regurgitation (IMR) is associated with increased mortality and recurrent congestive heart failure following coronary artery bypass graft (CABG) surgery. While mitral surgery should be undertaken for severe MR during CABG, the treatment of moderate IMR remains controversial. We conducted a meta-analysis to determine the outcomes of CABG alone and combine with mitral valve repair (MVr) in moderate IMR. ⋯ Our results show that in the presence of moderate IMR, adding MVr to revascularization reduces MR grade on follow-up echocardiography and promotes ventricular remodeling, with no improvement in long-term survival or functional class.

Acute pulmonary embolism (PE) with preserved hemodynamics but right ventricular dysfunction, classified as submassive PE, carries a high risk of mortality. We report the results for patients who did not qualify for medical therapy and required treatment of submassive PE with surgical pulmonary embolectomy and catheter-directed thrombolysis (CDT). ⋯ Pulmonary embolectomy and CDT are important contemporary advanced treatment options for selected high-risk patients with submassive PE, who do not qualify for medical therapy.

A variety of cardioplegic solutions are being used widely today to arrest the heart during coronary artery bypass grafting (CABG) and other cardiac operations. To minimize interruptions during the surgery for intermittent dosing of the cardioplegia and to facilitate less invasive cardiac procedures, single-shot solutions, including Bretschneider and del Nido solutions, have been introduced. This review examines the evidence regarding the safety and efficacy of Bretschneider and del Nido cardioplegia during CABG. The findings support their use in routine low-risk CABG, but finds insufficient evidence to support their safety in high-risk surgeries.

Circumflex aorta and double aortic arch are two forms of rare vascular rings. We present a case of an infant who was diagnosed with circumflex aorta and double aortic arch, and describe the surgical management of this rare anomaly.
