The objective was to describe the management and risk factors for complications of antiphospholipid syndrome (APS) patients who underwent a surgical procedure in a single center. We reviewed medical records of all patients with primary or secondary APS who underwent an elective surgery during a 6-year period. Demographical data, management of anticoagulation and complications were recorded. We identified 43 patients, mean age 37.9 ± 8.9 years, who underwent a total of 48 elective surgeries. All patients had history of at least one thrombotic event and were under vitamin K antagonists. Before surgery, all patients received bridging therapy with intravenous infusion of heparin or low molecular weight heparin (LMWH). Among the LMWH group, 36 had a full anticoagulation regimen and nine prophylactic doses. In 62% of the surgeries, we identified an optimal management of periprocedural anticoagulation according to guidelines. Overall six patients had severe bleeding and three thrombotic complications (full anticoagulation regimen n = 2 and prophylactic dose group n = 1). Patients with optimal management of anticoagulation experienced less thrombotic and hemorrhagic complications (7 vs. 33%; OR 0.14, 95% CI 0.02-0.81; p = 0.040) and patients with INR ≤1.5 at surgery had fewer episodes of major bleeding (6 vs. 29%; OR 0.19, 95% CI 0.02-0.98; p = 0.050). All three thrombotic events occurred in patients with INR ≤1.5. Proper management of anticoagulation based on guidelines is associated with less complications in patients with APS. Notwithstanding the proper use of bridging therapy, some patients may develop thrombotic complications.

The antioxidants as polyphenols, especially flavanols present in cocoa, exert a favorable effect on endothelium vasodilation, modulate inflammatory markers, and decrease platelet aggregation, lipid oxidation and insulin resistance. Recent nutritional intervention trials and molecular studies demonstrate that consumption of cocoa, particularly rich in flavanols, is beneficial to promote cardiovascular health. This review describes the cardiovascular effects of chocolate.

An asymptomatic 30-year-old male was referred for a transthoracic echocardiogram because of a systolic murmur that was noted on a pre-employment physical exam. Transthoracic imaging demonstrated a single papillary muscle from which the chordae of both mitral valve leaflets were attached. The mitral valve was seen to have a parachute-like configuration. Given the benign nature of the presentation, the patient did not seek further investigation.

Left ventricular assist devices (LVADs) are being increasingly implanted given the increasing prevalence of patients with advanced heart failure stages. However, they are not exempt from device malfunctions. A PubMed search for the key words (left ventricular assist device malfunction) (ventricular assist system malfunction) was performed. We identified 28 publications in the US Food and Drug Administration (FDA) website database that addressed LVAD malfunction. Twenty-nine FDA recalls were identified regarding LVAD malfunctions: 17 regarding HeartWare ventricular assist device, six for HeartMate II, three for HeartMate 3, and three for total artificial heart. Mechanisms involved in LVAD malfunction include battery malfunction, loose driveline connector, malfunction of the system controller, loose power supply connector ports, malfunction of the driveline splice kit, problems with the percutaneous lead connection, disconnection of the bend relief and outflow graft and outflow graft occlusion among others. Multiple mechanisms could be linked to LVAD malfunction. However, multiple device modifications have been developed over the past decade to avoid recurrent malfunctions. Constant improvements and research in biotechnology are needed to prevent these complications. It remains to be seen if newer generation devices will lead to improved patient outcomes over the long term.
